Description

确定高压发生器最大输出功率的方法和装置Method and apparatus for determining maximum output power of a high voltage generator

技术领域Technical field

本发明涉及高压设备技术领域，具体涉及确定高压发生器最大输出功率的方法和装置。The invention relates to the technical field of high voltage equipment, in particular to a method and a device for determining the maximum output power of a high voltage generator.

背景技术Background technique

高压设备一般包括：高压供电单元以及高压装置。其中，高压供电单元一般包括蓄电池组，电容器组以及高压发生器。高压设备都具有一定的尺寸限制，在蓄电池组的体积满足高压设备所能提供的体积内，其放电能力不足以使得高压发生器正常工作；因此，在蓄电池组与高压发生器之间增加电容器组，以提升蓄电池组的放电能力。该供电***具体在工作时，蓄电池组首先向电容器组充电；充电完成后，断开蓄电池组；通过电容器组的放电，向高压发生器提供电能；高压发生器利用电容器组提供的电能向高压装置输出功率，以便高压设备实现相应的功能。High voltage equipment generally includes: a high voltage power supply unit and a high voltage device. The high voltage power supply unit generally includes a battery pack, a capacitor bank and a high voltage generator. High-voltage equipment has a certain size limit. When the volume of the battery pack meets the volume that the high-voltage equipment can provide, its discharge capacity is not enough to make the high-voltage generator work normally; therefore, a capacitor bank is added between the battery pack and the high-voltage generator. To improve the discharge capacity of the battery pack. When the power supply system is in operation, the battery pack first charges the capacitor bank; after the charging is completed, the battery pack is disconnected; the electric energy is supplied to the high voltage generator through the discharge of the capacitor bank; the high voltage generator uses the electric energy provided by the capacitor bank to the high voltage device The output power is such that the high voltage device achieves the corresponding function.

高压设备在实际使用之前，用户按照需要实现的功能在该高压设备的操作界面上设置高压发生器的输出功率。然而，高压设备是通过高压供电单元中的蓄电池存储的电能进行工作的，随着不断的使用，蓄电池内存储的电能在不断减小，会导致高压发生器的实际输出功率在不断减小。因此，会出现用户所设置的高压发生器的输出功率，大于高压发生器实际能够输出的功率的情况，而该情况会导致该高压设备的使用效果不佳。Before the actual use of the high voltage device, the user sets the output power of the high voltage generator on the operation interface of the high voltage device according to the function required. However, the high-voltage equipment works by the electric energy stored in the battery in the high-voltage power supply unit. With continuous use, the electric energy stored in the battery is continuously reduced, and the actual output power of the high-voltage generator is continuously reduced. Therefore, there is a case where the output power of the high voltage generator set by the user is greater than the power that the high voltage generator can actually output, and this situation may result in poor use of the high voltage device.

具体实施方式detailed description

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

本领域技术人员应当理解的是，额定电量，用于表示蓄电池完全充电状态的容量；剩余电量(State of Charge，简称为SOC)，用于表示电池使用一段时间或长期搁置不用后的剩余容量与其完全充电状态的容量的比值，常用百分数表示。It should be understood by those skilled in the art that the rated power is used to indicate the capacity of the battery to fully charge state; the state of charge (SOC) is used to indicate the remaining capacity of the battery after using it for a period of time or for a long period of time. The ratio of the capacity of the fully charged state, expressed as a percentage.

本发明实施例提供了一种确定高压发生器最大输出功率的方法，可用于确定高压发生器最大输出功率的装置中，如图1所示，该方法包括以下步骤：Embodiments of the present invention provide a method for determining a maximum output power of a high voltage generator, which can be used in an apparatus for determining a maximum output power of a high voltage generator. As shown in FIG. 1, the method includes the following steps:

S11，获取高压供电单元中的至少一个蓄电池的剩余电量。S11. Acquire a remaining power of at least one battery in the high voltage power supply unit.

本实施例中的高压供电单元包括至少一个蓄电池，以及高压发生器，其中，蓄电池用于向高压发生器提供电能，蓄电池可以直接向高压发生器提供电能，也可以经过其他储能装置或其他电路向高压发生器提供电能。不论蓄电池与高压发生器具体的电路连接如何，该高压发生器是基于蓄电池提供的电能工作的。其中，高压供电单元中蓄电池的数量以及蓄电池之间的电连接方式可以根据具体情况进行具体设置。The high voltage power supply unit in this embodiment includes at least one battery, and a high voltage generator, wherein the battery is used to supply power to the high voltage generator, and the battery can directly supply power to the high voltage generator, or can pass other energy storage devices or other circuits. Power is supplied to the high voltage generator. Regardless of the specific circuit connection of the battery to the high voltage generator, the high voltage generator operates based on the electrical energy provided by the battery. Among them, the number of batteries in the high-voltage power supply unit and the electrical connection between the batteries can be specifically set according to specific conditions.

因此，蓄电池的剩余电量与高压发生器的输出功率直接相关。本实施例中，可以通过电池管理***(Battery Management System，简称为BMS)检测至少一个蓄电池的剩余电量，也可以通过其他检测装置进行剩余电量的检测。具体测量剩余电量的方法或装置可以根据实际情况进行调整，只需保证用于确定高压发生器最大输出功率的装置能够获取到高压供电单元中的至少一个蓄电池的剩余电量即可。Therefore, the remaining capacity of the battery is directly related to the output power of the high voltage generator. In this embodiment, the remaining power of at least one battery may be detected by a battery management system (Battery Management System, BMS for short), or the remaining power may be detected by other detecting devices. The method or device for measuring the remaining power can be adjusted according to the actual situation, and only the device for determining the maximum output power of the high voltage generator can obtain the remaining power of at least one of the high voltage power supply units.

S12，根据所获取的剩余电量所处的范围，确定高压发生器的最大输出功率。S12. Determine a maximum output power of the high voltage generator according to the range of the obtained remaining power.

确定高压发生器最大输出功率的装置根据获取到的剩余电量的所处的范围，确定当剩余电量处于不同范围时，对应的高压发生器的最大输出功率。The device for determining the maximum output power of the high voltage generator determines the maximum output power of the corresponding high voltage generator when the remaining power is in a different range according to the range of the obtained remaining power.

其中，对剩余电量对应的范围的划分越细，对应地，高压发生器相邻两个最大输出功率之间的差值越小，所确定出的高压发神器的最大输出功率的精度越高。Wherein, the finer the division of the range corresponding to the remaining power, correspondingly, the smaller the difference between the two adjacent maximum output powers of the high voltage generator, the higher the accuracy of the determined maximum output power of the high-voltage artifact.

本实施例中的至少一个蓄电池用于向高压发生器提供电能，通过蓄电池的实际能够向高压发生器提供电能的能力(蓄电池的剩余电量)，确定高压发生器的最大输出功率；即根据确定的最大输出功率，用户能够获知高压发生器当前的工作状态，从而避免了用户设置的高压发生器的输出功率高于该高压发生器实际能够提供的输出功率，提高了高压发生器的使用效果。At least one battery in this embodiment is used to supply electric energy to the high voltage generator, and the maximum output power of the high voltage generator is determined by the ability of the battery to actually supply electric energy to the high voltage generator (remaining power of the battery); The maximum output power, the user can know the current working state of the high voltage generator, thereby avoiding the output power of the high voltage generator set by the user is higher than the actual output power of the high voltage generator, and improving the use effect of the high voltage generator.

在本发明实施例的一些可选实施方式中，如图2所示，高压供电单元例如可以由至少一个蓄电池与高压发生器组成。其中，至少一个蓄电池直接与高压发生器连接，并且蓄电池的内阻小于预设值。In some optional embodiments of the embodiments of the present invention, as shown in FIG. 2, the high voltage power supply unit may be composed of, for example, at least one battery and a high voltage generator. Wherein at least one battery is directly connected to the high voltage generator, and the internal resistance of the battery is less than a preset value.

蓄电池11内阻的大小与制备蓄电池11的电池磁芯，蓄电池内电源线的长度，以及电源线内径有关。因此，可以通过选择内阻小的电池磁芯，缩短电源线的长度，或增加电源线的内径中的至少一种方法，制备内阻小于预设值的蓄电池11。The internal resistance of the battery 11 is related to the battery core of the battery 11 to be prepared, the length of the power supply line in the battery, and the inner diameter of the power supply line. Therefore, the battery 11 having an internal resistance smaller than a preset value can be prepared by selecting at least one of a battery core having a small internal resistance, shortening the length of the power supply line, or increasing the inner diameter of the power supply line.

此外，蓄电池11可以为锂电池，铅酸蓄电池，镍碱蓄电池，或其他类型可以充放电的电池中的一种。Further, the battery 11 may be one of a lithium battery, a lead acid battery, a nickel alkali battery, or another type of battery that can be charged and discharged.

在实际应用中，蓄电池11的数量以及各蓄电池11之间的串并联方式并不限于图2中所示，可以根据实际高压发生器20所需输出的功率进行具体设置。由于高压发生器20所需输出的功率越大，其所需的电能就越大，蓄电池11所需提供的电能的就越大。In practical applications, the number of the batteries 11 and the series-parallel connection between the batteries 11 are not limited to those shown in Fig. 2, and can be specifically set according to the power required by the actual high-voltage generator 20. The greater the power required by the high voltage generator 20, the greater the power required, and the greater the electrical energy that the battery 11 needs to provide.

为下文描述方便，将与高压发生器20直接连接的至少一个蓄电池11称之为电池模块，该电池模块可以包括彼此连接的多个蓄电池11。例如，可以包括700个蓄电池11，即，以70个蓄电池11的串联连接为一组模块，依次并联10组模块。电池模块10直接与高压发生器20连接，即电池模块10直接向高压发生器放电，以供给高压发生器20的工作。For convenience of the following description, at least one battery 11 directly connected to the high voltage generator 20 is referred to as a battery module, and the battery module may include a plurality of batteries 11 connected to each other. For example, 700 batteries 11 may be included, that is, a series connection of 70 batteries 11 is a group of modules, and 10 groups of modules are sequentially connected in parallel. The battery module 10 is directly connected to the high voltage generator 20, that is, the battery module 10 is directly discharged to the high voltage generator to supply the operation of the high voltage generator 20.

本申请发明人经过多次实验得出，蓄电池单独向高压发生器放电的能力不足的原因在于蓄电池使用过程中的压降过大，并不在于蓄电池的具体数量，而在于蓄电池的内阻过大。因此，在本实施例中，通过在供电单元内设置内阻小于预设值的蓄电池，使得本实施例中的供电单元即使在没有电容器组的情况下，也能够提供高压发生器工作所需的电能。本实施例提供的用于向高压设备供电的供电单元省却了现有技术中的供电单元所必需的电容器组，同时高压设备仍能够正常工作，从而避免了现有技术中电容器组内剩余电量的释放而导致的蓄电池电量损失，提升了高压设备的续航时间。The inventor of the present application has obtained many experiments that the reason for the insufficient capacity of the battery to discharge to the high voltage generator alone is that the voltage drop during the use of the battery is too large, not the specific number of the battery, but the internal resistance of the battery is too large. . Therefore, in the embodiment, by providing a battery having an internal resistance smaller than a preset value in the power supply unit, the power supply unit in the embodiment can provide the high voltage generator for operation even in the absence of the capacitor bank. Electrical energy. The power supply unit for supplying power to the high voltage device provided by the embodiment saves the capacitor group necessary for the power supply unit in the prior art, and the high voltage device can still work normally, thereby avoiding the remaining power in the capacitor bank in the prior art. The loss of battery power caused by the release increases the life time of the high voltage equipment.

其中，可选地，预设值为25毫欧，即蓄电池11的内阻小于25毫欧。例如，按照上文中的电池模块10的连接方式，该电池模块10的内阻小于175毫欧，即25×70÷10＝175毫欧。Optionally, the preset value is 25 milliohms, that is, the internal resistance of the battery 11 is less than 25 milliohms. For example, in accordance with the manner in which the battery module 10 is connected above, the internal resistance of the battery module 10 is less than 175 milliohms, that is, 25 x 70 ÷ 10 = 175 milliohms.

发明人在经过多次实验证明，在蓄电池内阻小于25毫欧的情况下，其内阻所消耗的电压就会降低。其中，测试环境如下所述：测试采用上文所述的电池模块，(包括700个蓄电池11，即，以70个蓄电池11的串联连接为一组模块，依次并联10组模块)，电池模块的电压为265V左右，用户所需求的放电电流为175A，放电时间1S。具体测试数据如表1所示：The inventor has proved through many experiments that the voltage consumed by the internal resistance is reduced when the internal resistance of the battery is less than 25 milliohms. The test environment is as follows: the test adopts the battery module described above, (including 700 batteries 11 , that is, a series connection of 70 batteries 11 as a group of modules, sequentially paralleling 10 groups of modules), the battery module The voltage is about 265V, the discharge current required by the user is 175A, and the discharge time is 1S. The specific test data is shown in Table 1:

表1测试数据Table 1 test data

其中，在放电20ms之后(即在电池模块的放电电压稳定之后)，测量高压发生器的输入电压。从上表数据可以看出，在供电单元的内阻小于240毫欧时，电池模块的放电电流能够达到200A；在供电单元的内阻小于250毫欧时，电池模块的放电电流能够达到150A。Here, the input voltage of the high voltage generator is measured after 20 ms of discharge (that is, after the discharge voltage of the battery module is stabilized). As can be seen from the above table data, when the internal resistance of the power supply unit is less than 240 milliohms, the discharge current of the battery module can reach 200A; when the internal resistance of the power supply unit is less than 250 milliohms, the discharge current of the battery module can reach 150A.

由上表中的数据，除去电池模块与高压发生器之间相关连接电缆的电阻，按照电池模块内各蓄电池组的串并联关系，能够反向计算推导出，当蓄电池的内阻小于25毫欧时，本实施例中的蓄电池11具有足够大的放电能力，能够满足高压设备大电流放电的要求。From the data in the above table, the resistance of the relevant connecting cable between the battery module and the high voltage generator is removed, and according to the series-parallel relationship of the battery packs in the battery module, the reverse calculation can be derived, when the internal resistance of the battery is less than 25 milliohms. When the battery 11 in this embodiment has a sufficiently large discharge capacity, it can meet the requirements of high-current discharge of a high-voltage device.

因此，与高压发生器20直接连接的至少一个蓄电池11的总内阻加上连接电缆的内阻总和小于200毫欧，在使用过程中，至少一个蓄电池11以及连接电缆上的电压降较小，一方面能够保证蓄电池的放电能力；另一方面，蓄电池的放电能力提升，在同样的放电需求的情况下，通过本发明中较少数量的蓄电池即可实现，即高压供电单元所占的体积较小，能够实现高压设备的小型化。Therefore, the total internal resistance of the at least one battery 11 directly connected to the high voltage generator 20 plus the internal resistance of the connecting cable is less than 200 milliohms, and the voltage drop on at least one of the batteries 11 and the connecting cable is small during use. On the one hand, the discharge capacity of the battery can be ensured; on the other hand, the discharge capacity of the battery is improved, and in the case of the same discharge demand, the battery can be realized by a small number of batteries in the invention, that is, the volume occupied by the high-voltage power supply unit is relatively small. Small, it can realize the miniaturization of high-voltage equipment.

在蓄电池11的内阻小于预设值的情况下，蓄电池11在放电过程中，由于其内阻所消耗的电压就会降低，即蓄电池11两端的压降就会减小，从而使得蓄电池11具有足够大的放电能力；此外，将电池模块10直接与高压发生器20连接，即通过电池模块10直接向高压发生器20提供电源。在蓄电池的内阻小于预设值的前提条件下，通过至少一个蓄电池11直接与高压发生器20连接，能够避免使用电容器组提升蓄电池的放电能力，提高了高压供电单元的利用率，进而提高应用该高压供电单元供电的高压设备的续航能力。In the case where the internal resistance of the battery 11 is less than the preset value, the voltage consumed by the internal resistance of the battery 11 during the discharge of the battery 11 is lowered, that is, the voltage drop across the battery 11 is reduced, so that the battery 11 has The discharge capacity is large enough; in addition, the battery module 10 is directly connected to the high voltage generator 20, that is, the power is directly supplied to the high voltage generator 20 through the battery module 10. Under the premise that the internal resistance of the battery is less than the preset value, the at least one battery 11 is directly connected to the high voltage generator 20, which can avoid the use of the capacitor bank to improve the discharge capacity of the battery, improve the utilization rate of the high voltage power supply unit, and further improve the application. The endurance of the high voltage equipment powered by the high voltage power supply unit.

可选地，如图3所示，应用该高压供电单元的高压设备，还包括与至少一个蓄电池11并联的预充电电路30。该预充电电路30的具体结构如图 4所示，包括串联连接的控制支路31和电容C1。其中，控制支路31包括：并联连接的第一支路和第二支路；第一支路包括串联连接的第一开关K1和电阻；第二支路包括第二开关K2。Optionally, as shown in FIG. 3, the high voltage device to which the high voltage power supply unit is applied further includes a precharge circuit 30 in parallel with at least one battery 11. The specific structure of the precharge circuit 30 is as shown in FIG. 4, and includes a control branch 31 and a capacitor C1 connected in series. The control branch 31 includes: a first branch and a second branch connected in parallel; the first branch includes a first switch K1 and a resistor connected in series; and the second branch includes a second switch K2.

该预充电电路30的具体工作过程如下：The specific working process of the pre-charging circuit 30 is as follows:

(1)蓄电池11开始放电时，K1闭合，K2断开，此时预充电电路30为电阻R1以及电容C1的串联，形成一阶电路。蓄电池11向电容C1充电，在充电过程中实施测量电容C1两端的电压。当电容C1两端的电压达到预先设定的电压值后，断开第一开关K1，闭合第二开关K2。(1) When the battery 11 starts to discharge, K1 is closed and K2 is turned off. At this time, the precharge circuit 30 is a series connection of the resistor R1 and the capacitor C1 to form a first-order circuit. The battery 11 charges the capacitor C1, and the voltage across the capacitor C1 is measured during charging. When the voltage across the capacitor C1 reaches a predetermined voltage value, the first switch K1 is turned off, and the second switch K2 is closed.

(2)第二开关K2闭合，第一开关K1断开，此时电容C1与蓄电池11并联，实现蓄电池11向高压发生器20放电的过渡。(2) The second switch K2 is closed, and the first switch K1 is turned off. At this time, the capacitor C1 is connected in parallel with the battery 11 to realize the transition of the battery 11 to the high voltage generator 20.

通过控制支路31控制预充电电路30的工作状态，一方面能够避免冲击电流对高压发生器20的损害；另一方面，在过渡完成之后，将第一支路中的电阻R1从预充电电路30中断开，能够减小电阻R1上的压降对蓄电池放电的影响。By controlling the operating state of the pre-charging circuit 30 by the control branch 31, on the one hand, the damage of the high-voltage generator 20 by the inrush current can be avoided; on the other hand, after the transition is completed, the resistor R1 in the first branch is taken from the pre-charging circuit. The disconnection in 30 can reduce the effect of the voltage drop across the resistor R1 on the discharge of the battery.

在本发明的一些可选实施方式中，高压设备包括移动DR设备(Digital Radiography，简称为DR)，又称为移动数字化直接成像设备。In some alternative embodiments of the invention, the high voltage device comprises a Digital Radiography (DR), also known as a mobile digital direct imaging device.

具体地，移动DR设备，是用来对一些不能移动(如正在使用生命支持设备)、移动困难(如骨折患者)或移动过程可导致生命危险的患者(如心梗、肺栓塞等患者)进行床边数字成像。Specifically, the mobile DR device is used for patients who are unable to move (such as using a life support device), who have difficulty moving (such as a fractured patient), or who are at risk of life during a moving procedure (such as a myocardial infarction, a pulmonary embolism, etc.). Bedside digital imaging.

移动DR设备包括上述实施例中的高压供电单元以及射线球管，其中，高压发生器20为将输入其的电压转换成高压后，向射线球管提供的电能，使得射线球管的阴、阳极之间具有高电压差(高达上千伏)，产生射线；并利用射线球管产生的射线对人体进行照射；对透过人体的射线进行采集、转换，并使之成为可见的影像，即为人体数字化成像。The mobile DR device includes the high voltage power supply unit and the ray tube in the above embodiment, wherein the high voltage generator 20 converts the voltage input thereto into a high voltage, and supplies the electric energy to the ray tube, so that the anode and the anode of the ray tube There is a high voltage difference (up to thousands of volts) to generate radiation; and the radiation generated by the ray tube is used to illuminate the human body; the ray passing through the human body is collected, converted, and made visible, which is Digital imaging of the human body.

由于射线的能量不同，其所能够穿透人体的组织不同，即对于不同的人体组织，对于射线的能量需求不同，而射线的能量取决于高压发生器的输出功率。由于高压发生器的输出功率不同，对应地，射线球管的阴、阳极之间的高电压差不同，从而所产生的射线的能量不同。因此，在移动DR 设备使用前，用户需要在该设备的操作界面上设置高压发生器的输出功率。Due to the different energy of the ray, the tissue that can penetrate the human body is different, that is, for different human tissues, the energy demand for the ray is different, and the energy of the ray depends on the output power of the high voltage generator. Since the output power of the high voltage generator is different, correspondingly, the high voltage difference between the cathode and the anode of the ray tube is different, so that the energy of the generated rays is different. Therefore, before using the mobile DR device, the user needs to set the output power of the high voltage generator on the operation interface of the device.

然而，移动DR设备是通过供电***中存储的电能进行工作的，随着不断的使用，供电***内存储的电能在不断减小，会导致高压发生器的实际输出功率在不断减小。因此，通过本发明实施例中的方法确定出高压发生器的最大输出功率，会避免用户所设置的高压发生器的输出功率，大于高压发生器实际能够输出的功率的情况，从而能够提高该移动DR设备的成像效果。However, the mobile DR device works by the electrical energy stored in the power supply system. As the power is continuously used, the power stored in the power supply system is continuously reduced, which causes the actual output power of the high voltage generator to be continuously reduced. Therefore, determining the maximum output power of the high voltage generator by the method in the embodiment of the present invention avoids the output power of the high voltage generator set by the user, which is greater than the actual power output of the high voltage generator, thereby improving the movement. The imaging effect of the DR device.

图5示出了根据本发明另一实施例的确定高压发生器最大输出功率的方法，该方法包括以下步骤：FIG. 5 illustrates a method of determining a maximum output power of a high voltage generator in accordance with another embodiment of the present invention, the method comprising the steps of:

S21，获取高压供电单元中的至少一个蓄电池的剩余电量。详细内容请参照步骤S11所述。S21. Acquire a remaining power of at least one battery in the high voltage power supply unit. For details, please refer to step S11.

S22，确定剩余电量所处的范围。S22, determining a range in which the remaining power is located.

本实施例中将剩余电量所处的范围划分为3个等级，即对应地，高压发生器的最大输出功率分为3个等级。当剩余电量大于或等于第一电量阈值时，执行步骤S23；当剩余电量小于第一电量阈值且大于第二电量阈值时，执行步骤S24；当剩余电量小于或等于第二电量阈值时，执行步骤S25。In this embodiment, the range in which the remaining power is located is divided into three levels, that is, correspondingly, the maximum output power of the high voltage generator is divided into three levels. When the remaining power is greater than or equal to the first power threshold, step S23 is performed; when the remaining power is less than the first power threshold and greater than the second power threshold, step S24 is performed; when the remaining power is less than or equal to the second power threshold, performing steps S25.

S25，确定高压发生器的最大输出功率为第二功率，第二功率小于第一功率。S25. Determine that the maximum output power of the high voltage generator is the second power, and the second power is less than the first power.

随着蓄电池的不断使用，高压发生器的最大输出功率依次减小，即额定功率大于第一功率大于第二功率。其中，具体的第一电量阈值，第二电量阈值的数值以及对应的最大输出功率，可以是根据多次实验得出，也可以是根据蓄电池的内阻大小进行具体设置。With the continuous use of the battery, the maximum output power of the high voltage generator is sequentially reduced, that is, the rated power is greater than the first power is greater than the second power. The specific first power threshold, the second power threshold, and the corresponding maximum output power may be determined according to multiple experiments, or may be specifically set according to the internal resistance of the battery.

与图1所示的方法相比，本实施例中利用剩余电量所处的具体范围，将高压发生器能够输出的最大功率划分为三个等级；即依据蓄电池在使用过程中的不同状态，确定高压发生器的最大输出功率，使得用户在使用高压发生器的过程中，能够实时获知高压发生器所能够输出的最大功率，便于用户及时调整对高压发生器输出功率的需求；此外，还能够保证剩余电量较低时，高压发生器可以输出功率，增加了蓄电池的利用率。Compared with the method shown in FIG. 1 , in the embodiment, the maximum power that the high-voltage generator can output is divided into three levels by using the specific range of the remaining power; that is, according to different states of the battery during use, The maximum output power of the high-voltage generator enables the user to know the maximum power that the high-voltage generator can output in real time during the process of using the high-voltage generator, so that the user can timely adjust the output power of the high-voltage generator; in addition, it can guarantee When the remaining power is low, the high voltage generator can output power, which increases the utilization of the battery.

作为本实施例的一种可选实施方式，第一电量阈值为20％，第二电量阈值为10％，具体剩余电量与高压发生器的最大输出功率之间的对应关系，如表2所示：As an optional implementation manner of this embodiment, the first power threshold is 20%, the second power threshold is 10%, and the correspondence between the specific remaining power and the maximum output power of the high voltage generator is as shown in Table 2. :

表2剩余电量与高压发生器的最大输出功率之间的对应关系Correspondence between the remaining power of Table 2 and the maximum output power of the high voltage generator

剩余电量remaining battery	最大输出功率Maximum output power

(10％，20％)(10%, 20%)	第一功率First power
(0，10％](0,10%)	第二功率Second power

其中，第一功率为0.3-0.5倍的额定功率；第二功率为小于0.3倍的额定功率。Wherein, the first power is 0.3-0.5 times the rated power; the second power is less than 0.3 times the rated power.

例如，对应于表1，高压发生器的额定功率为50KW，第一功率为20KW，第二功率为12KW。For example, corresponding to Table 1, the rated power of the high voltage generator is 50 KW, the first power is 20 KW, and the second power is 12 KW.

In theory, the output voltage of the battery pack and the input voltage of the high voltage generator should be the same. However, in the actual working process of the battery pack and the high voltage generator, unequal conditions may occur. When the difference between the output voltage and the input voltage exceeds a preset value, it is necessary to stop the battery pack from discharging, and stop the shutdown. To ensure the safety of the battery pack discharge.

其中，可以通过同一检测装置分别测量至少一个蓄电池的输出电压，以及高压发生器的输入电压；也可以通过不同的检测装置分别检测，例如，对蓄电池组可以采用BMS检测，对高压发生器可以采用其自身的母线检测电路进行实时的电压检测。Wherein, the output voltage of the at least one battery and the input voltage of the high voltage generator can be respectively measured by the same detecting device; or can be separately detected by different detecting devices, for example, the battery pack can be detected by BMS, and the high voltage generator can be used.

When the difference is greater than the preset value, step S34 is performed; otherwise, step S35 is performed.

S34，确定剩余电量异常。S34, determining that the remaining power is abnormal.

当S33中判断出输出电压与输入电压的差值大于预设值时，能够确定剩余电量异常，即蓄电池组放电异常，此时需要立即停机检查，以保证蓄电池的放电安全。When it is determined in S33 that the difference between the output voltage and the input voltage is greater than a preset value, it can be determined that the remaining power is abnormal, that is, the battery pack is abnormally discharged, and an immediate shutdown check is required to ensure the discharge safety of the battery.

S35，根据所获取的剩余电量所处的范围，确定高压发生器的最大输出功率。S35. Determine a maximum output power of the high voltage generator according to the range of the obtained remaining power.

For details, please refer to the description of step S22 to step S25 of the embodiment shown in FIG. 5, and details are not described herein again.

作为本实施例的一种可选实施方式，可以根据高压发生器自身的母线检测电路监测出的高压发生器的输入电压，确定高压发生器的最大输出功率。具体地，As an optional implementation manner of this embodiment, the maximum output power of the high voltage generator may be determined according to the input voltage of the high voltage generator monitored by the bus detection circuit of the high voltage generator itself. specifically,

当输入电压大于等于电压阈值时，最大输出功率为额定功率；When the input voltage is greater than or equal to the voltage threshold, the maximum output power is the rated power;

当输入电压小于电压阈值时，最大输出功率小于额定功率。When the input voltage is less than the voltage threshold, the maximum output power is less than the rated power.

与图1或图5所示的方法相比，本实施例中蓄电池的输出与高压发生器的输入直接连接，通过判断蓄电池组的输出电压与输入电压之间差值是否超出预设值，进行蓄电池组剩余电量是否异常的判断，保证了蓄电池组放电的安全性。Compared with the method shown in FIG. 1 or FIG. 5, the output of the battery in the embodiment is directly connected to the input of the high voltage generator, and it is determined whether the difference between the output voltage of the battery pack and the input voltage exceeds a preset value. The judgment of whether the remaining capacity of the battery pack is abnormal ensures the safety of the discharge of the battery pack.

例如，高压发生器以第一功率作为最大输出功率，那么，每次高压发生器工作时，持续以第一功率输出的时间，为输出最大功率的持续时间。For example, the high voltage generator uses the first power as the maximum output power, and then, each time the high voltage generator operates, the time at which the first power is output is the duration of the output maximum power.

本实施例中，持续时间与蓄电池的剩余电量，高压发生器的最大输出功率，输出最大功率的次数，以及蓄电池的输出电压相关。具体地，可以采用如下公式计算高压发生器每次输出最大功率的持续时间：In this embodiment, the duration is related to the remaining capacity of the battery, the maximum output power of the high voltage generator, the number of times the maximum power is output, and the output voltage of the battery.
