请参阅图1,图1示出了本申请实施例提供的一种电池充电方法的实现流程图,该方法包括如下步骤:Please refer to FIG. 1. FIG. 1 shows a flowchart for implementing a battery charging method provided by an embodiment of the present application. The method includes the following steps:
S101、采样电池在充电时的充电数据,所述充电数据包括温度、电池剩余容量以及单体电压。S101. Sampling charging data of the battery during charging, where the charging data includes temperature, remaining capacity of the battery, and cell voltage.
在应用中,上述电池可以为锂离子电池、蓄电池等充电电池。上述采样可以为实时对电池进行数据采样,也可以为每隔预设时间对电池进行一次采样,对此不作限定。上述电池在充电时将改变电池的温度、电池剩余容量以及电池充电时的单体电压。其中,对电池温度进行采样,可以由温度传感器进行采样,也可在电池的表面设置热敏电阻(Negative Temperature Coefficient,NTC)进行采样。因热敏电阻可随温度上升电阻呈指数关系减小,因此,可通过实时监测热敏电阻的阻值,并根据阻值确定对应的温度。对于电池剩余容量可以由电量计负责采样,电量计可监测电池在放电时的放电量,以及监测电池在充电时的充电量,并以此进行计算电池的剩余容量。对于单体电压,可以由电池的模拟前端(Active Front End,AFE)进行采样,模拟前端作为电池的输入端,可对模拟信号进行处理,适用于采集电压、电流等数据。In applications, the above-mentioned batteries may be rechargeable batteries such as lithium-ion batteries, accumulators, and the like. The foregoing sampling may be data sampling of the battery in real time, or may be sampling of the battery once every preset time, which is not limited. The above-mentioned battery will change the temperature of the battery, the remaining capacity of the battery and the cell voltage when the battery is charged when the battery is charged. Among them, the battery temperature can be sampled by a temperature sensor, or a thermistor (Negative Temperature Coefficient, NTC) can be set on the surface of the battery for sampling. Because the resistance of the thermistor can decrease exponentially with the rise of temperature, the resistance value of the thermistor can be monitored in real time, and the corresponding temperature can be determined according to the resistance value. The remaining capacity of the battery can be sampled by the fuel gauge, and the fuel gauge can monitor the discharge capacity of the battery during discharge and monitor the charge capacity of the battery during charging, and use this to calculate the remaining capacity of the battery. For the cell voltage, it can be sampled by the analog front end (Active Front End, AFE) of the battery. The analog front end acts as the input end of the battery and can process the analog signal, which is suitable for collecting data such as voltage and current.
在应用中,终端设备在对电池进行一次数据采样时,可对应将采样得到的充电数据分别存储至寄存器的指定位置中,而后由终端设备根据预先设置的获取路径,从指定位置处获取充电数据。然而,在对电池进行采样时,可能发生采样断线导致采样数据不准确的情况,并产生充电隐患。因此,若未采样得到电池在充电时的充电数据,和/或,采样得到的任一充电数据为无效数据,则将电池的安全充电电压设定为预设电压,并设定电池的安全充电电流为预设电流。In the application, when the terminal device samples the battery once, it can correspondingly store the sampled charging data in the specified location of the register, and then the terminal device acquires the charging data from the specified location according to the preset acquisition path. . However, when sampling the battery, the sampling disconnection may occur, resulting in inaccurate sampling data and hidden dangers of charging. Therefore, if the charging data of the battery during charging is not sampled, and/or any charging data obtained by sampling is invalid data, the safe charging voltage of the battery is set to the preset voltage, and the safe charging of the battery is set The current is the preset current.
在具体应用中,上述无效数据包括任一充电数据采样失败,以及采样得到的任一充电数据不准确,则该充电数据即为无效数据。上述预设电压和预设电流均为采样得到的充电数据为无效数据时,为保证充电安全而进行设置的安全数值。该安全数值可根据实际情况进行设置,例如,可设置预设电压为0V,预设电流为0A。示例性的,对于充电数据为无效数据,可以为电池发生温度采样断线、电压采样断线、电量计与终端设备通信故障等情况。具体的,可通过电池的模拟前端对采样的充电数据进行处理,判断充电数据是否为无效数据。例如,电池若发生电压采样断线的情况,则发生电压采样线断线的该点电压将会被采样线的上下两个内阻分压,进而得到错误的采样值。因此,若不及时改变充电电压和充电电流,则可能会造成电池过充的故障。In a specific application, if the above invalid data includes any charging data sampling failure, and any charging data obtained by sampling is inaccurate, the charging data is invalid data. The above preset voltage and preset current are both safe values set to ensure charging safety when the sampled charging data is invalid data. The safety value can be set according to the actual situation. For example, the preset voltage can be set to 0V and the preset current can be set to 0A. Exemplarily, for the charging data to be invalid data, it may be that the temperature sampling disconnection, the voltage sampling disconnection, or the communication failure between the fuel gauge and the terminal device occurs in the battery. Specifically, the sampled charging data can be processed by the analog front end of the battery to determine whether the charging data is invalid data. For example, if the voltage sampling disconnection occurs in the battery, the voltage at the point where the disconnection of the voltage sampling line occurs will be divided by the upper and lower internal resistances of the sampling line, thereby obtaining an incorrect sampling value. Therefore, if the charging voltage and charging current are not changed in time, the battery may be overcharged.

The terminal device can pre-store the corresponding table of each cell voltage and the maximum charging rate of the battery at different temperatures, and the corresponding table of the remaining capacity of each battery and the maximum charging rate of the battery at different temperatures, and then can determine the first charging rate according to the charging data. and the second charging rate. Wherein, any of the above maximum charging rates are the maximum safe charging rates recorded in the battery charging specification and/or test report.
在应用中,对于上述不同温度下的单体电压与最大充电倍率对应表,其电池温度需处于电池的充电规格书允许的使用温度范围内。若确定电池的温度超过温度范围时,则可认为采样的温度数据属于无效数据,并将电池的安全充电电压设定为预设电压,并设定电池的安全充电电流为预设电流。其中,电池的单体电压也不能超过电池的充电规格书允许的最大充电电压,否则也将单体电压判定为无效数据,对此不再进行说明。In the application, for the above-mentioned correspondence table between the cell voltage and the maximum charging rate at different temperatures, the battery temperature should be within the operating temperature range allowed by the battery's charging specification. If it is determined that the temperature of the battery exceeds the temperature range, it may be considered that the sampled temperature data is invalid data, the safe charging voltage of the battery is set to the preset voltage, and the safe charging current of the battery is set to the preset current. Among them, the cell voltage of the battery cannot exceed the maximum charging voltage allowed by the charging specification of the battery, otherwise, the cell voltage will also be determined as invalid data, which will not be described again.

在应用中,上述目标充电倍率可以为第一充电倍率,或第二充电倍率,或第一充电倍率与第二充电倍率的平均值,对此不作限定。然而,上述第一充电倍率与第二充电倍率是由不同充电数据进行确定的。因此,为了使电池可以在安全充电的同时且可提高充电效率,可设定目标充电倍率为第一充电倍率与第二充电倍率中的最小值。进而,可确保电池在充电时的安全,不会产生电池过充或电池高温失控的风险。In application, the target charging rate may be the first charging rate, the second charging rate, or the average value of the first charging rate and the second charging rate, which is not limited. However, the above-mentioned first charging rate and second charging rate are determined by different charging data. Therefore, in order to allow the battery to be safely charged and at the same time to improve the charging efficiency, the target charging rate may be set to be the minimum value between the first charging rate and the second charging rate. Furthermore, the safety of the battery during charging can be ensured, and there is no risk of overcharging the battery or running out of control of the battery at high temperature.
S104、获取所述电池的安全充电电压,并根据所述目标充电倍率计算安全充电电流。S104. Acquire a safe charging voltage of the battery, and calculate a safe charging current according to the target charging rate.
在应用中,上述安全充电电压可以为电池的充电规格书和/或测试报告上记载的最大充电电压,且该充电电压预先存储在终端设备的指定路径下由终端设备进行获取,也可以为终端设备根据当前充电数据以及充电电压进行计算得到的最大允许充电电压,对此不作限定。其中,安全充电电流可以为根据当前充电数据以及目标充电倍率进行计算得到的最大允许充电电流。In application, the above safe charging voltage can be the maximum charging voltage recorded in the battery charging specification and/or test report, and the charging voltage is pre-stored in the designated path of the terminal device for acquisition by the terminal device, or it can be the terminal device. The maximum allowable charging voltage calculated by the device according to the current charging data and the charging voltage is not limited. The safe charging current may be the maximum allowable charging current calculated according to the current charging data and the target charging rate.
在应用中,上述安全充电电流为根据目标充电倍率进行计算得到的,然而,目标充电倍率与采样电池在充电时的充电数据有关。电池在充电时电池剩余容量必定会发生改变,且温度以及单体电压可能也会发生改变,进而确定的目标充电倍率将会改变。因此,计算得到的安全充电电流将随采样电池的充电数据的进行变化,使电池在充电时的充电电流一直处于合理范围内。In the application, the above safe charging current is calculated according to the target charging rate, however, the target charging rate is related to the charging data of the sampled battery during charging. When the battery is being charged, the remaining capacity of the battery will definitely change, and the temperature and cell voltage may also change, so the determined target charging rate will change. Therefore, the calculated safe charging current will change with the charging data of the sampled battery, so that the charging current of the battery during charging is always within a reasonable range.
S105、按照所述安全充电电压和所述安全充电电流,对所述电池进行充电。S105. Charge the battery according to the safe charging voltage and the safe charging current.
在应用中,根据S104内容可知上述安全充电电压只与最大充电电压有关,该数值在充电期间可认为属于固定值。因此,可保持输入的安全充电电压不变,使输入的充电电压不会发生电压过大的情况。另外,可根据采样得到的充电数据改变安全充电电流,实现电池在充电时的恒压限流充电的效果,进而可在保证充电安全的情况下,根据目标充电倍率改变充电电流,提高电池的充电效率。In application, according to the content of S104, it can be known that the above-mentioned safe charging voltage is only related to the maximum charging voltage, and this value can be regarded as a fixed value during the charging period. Therefore, the input safe charging voltage can be kept unchanged, so that the input charging voltage will not be too large. In addition, the safe charging current can be changed according to the sampled charging data, so as to realize the effect of constant voltage and current limiting charging when the battery is charging, and then the charging current can be changed according to the target charging rate while ensuring the charging safety, so as to improve the charging of the battery. effectiveness.

在应用中,在电池具有多个时,可认为充电对象为电池包,此时电池剩余容量即为电池包剩余容量。若电池包内每个电池的剩余容量均不一致,则可获取每个电池的剩余容量,并将最低剩余容量作为电池包剩余容量,或者,将最高电池剩余容量作为电池包剩余容量,或者,将多个电池的平均电池剩余容量作为电池包剩余容量,对此不作限定。In the application, when there are multiple batteries, the charging object can be considered as the battery pack, and the remaining capacity of the battery at this time is the remaining capacity of the battery pack.

Therefore, in order to determine the first charging rate when charging multiple batteries, the minimum charging temperature and the maximum charging temperature among the multiple batteries can be determined by comparing the temperatures of the multiple batteries. within the scope of the person. Therefore, it can be considered that when the remaining capacities of the battery packs are the same, the charging rate determined according to the temperature of the remaining batteries is between the third charging rate determined according to the minimum charging temperature and the fourth charging rate determined according to the maximum charging temperature. Therefore, it is only necessary to determine the third charging rate and the fourth charging rate, and the steps for the terminal device to query the remaining charging rates are reduced.

在应用中,在对电池包进行充电时,因每个电池包的规格可能不一致,因此,在充电时的单体电压可能也各不相同。为使电池包在充电时各个电池的均处于安全充电电流的范围内,可根据电池包中充电温度以及单体电压的极限值确定第二充电倍率,忽略查询其余充电温度以及单体电压对应的充电倍率,减少终端设备查询其余充电倍率的步骤。具体的,获取电池包中每个电池在充电时的温度,确定最小充电温度和最大充电温度,并确定每个电池在充电时的单体电压,确定最大单体电压和最小单体电压。并根据温度-单体电压-最大充电倍率的对应表,确定最小充电温度和最小单体电压对应的第五充电倍率,确定最小充电温度和最大单体电压对应的第六充电倍率,确定最大充电温度和最小单体电压对应的第七充电倍率,以及确定最大充电温度和最大单体电压对应的第八充电倍率。In applications, when charging battery packs, the specifications of each battery pack may be inconsistent, so the cell voltages during charging may also be different. In order to make each battery within the safe charging current range when the battery pack is being charged, the second charging rate can be determined according to the charging temperature in the battery pack and the limit value of the cell voltage. The charging rate reduces the steps for the terminal device to query the remaining charging rates. Specifically, the temperature of each battery in the battery pack during charging is obtained, the minimum charging temperature and the maximum charging temperature are determined, the cell voltage of each battery during charging is determined, and the maximum cell voltage and the minimum cell voltage are determined.

在应用中,上述单个电池的充电截止电压可根据电池的充电规格书进行确定。其中,充电截止电压为在规定的恒流充电期间,蓄电池到达完全充电状态时的电压,到达充电截止电压后若仍继续充电,即为过充电,将会损害电池性能和使用寿命。一般来说,一个电池包内的多个电池,都是属于同一型号的电池,其单个电池的充电截止电压都是相同的。即可认为对于多个电池,其最大允许充电电压可认为与单个充电截止电压有关。具体的,最大允许充电电压的计算公式可为:V’=V*N;其中,V’为最大允许充电电压,V为电池包中单个电池的充电截止电压,N为电池包中多个电池的数量。通过计算多个电池在充电时的安全充电电压,可有效控制电池在充电时的输入电压均处于安全充电电压内,保证电池的充电安全和降低对电池性能的损害,延迟电池的使用寿命。In application, the cut-off voltage of the above single battery can be determined according to the charging specification of the battery. Among them, the charging cut-off voltage is the voltage when the battery reaches a fully charged state during the specified constant current charging period. If the battery continues to charge after reaching the charging cut-off voltage, it is overcharged, which will damage the performance and service life of the battery. Generally speaking, multiple batteries in a battery pack belong to the same type of batteries, and the charge cut-off voltages of individual batteries are the same. That is to say, for multiple batteries, the maximum allowable charging voltage can be considered to be related to a single charging cut-off voltage. Specifically, the calculation formula of the maximum allowable charging voltage can be: V'=V*N; where V' is the maximum allowable charging voltage, V is the charging cut-off voltage of a single battery in the battery pack, and N is the multiple batteries in the battery pack. quantity. By calculating the safe charging voltage of multiple batteries during charging, the input voltage of the battery during charging can be effectively controlled to be within the safe charging voltage, ensuring the charging safety of the battery, reducing the damage to the battery performance, and delaying the service life of the battery.

Battery state of health (SOH, State Of Health) is the value calculated according to the capacity and rated capacity of the battery when it is fully charged, which is the battery health state. Under normal circumstances, when the battery is used for a period of time, the capacity of the battery when fully charged will be lower than the rated capacity of the battery. Among them, the nominal capacity can be obtained according to the charging specification of the battery, and the state of health of the battery can be calculated from the ratio between the capacity when the battery is fully charged by the fuel gauge and the rated capacity set in the charging specification of the battery. For the battery state of health of a battery, capacity decay usually occurs after multiple charges and discharges. Therefore, the battery health state of the battery can be set to be sampled every preset time period, and updated and stored. When the battery is charging, obtain the last collected battery health state to participate in the calculation.

By calculating the state of health of the battery at the current moment, the degree of capacity attenuation of the battery after multiple cycles is determined, and then the safe charging current of the battery at the current moment can be determined according to the degree of capacity attenuation and the target charging rate. Realize the intelligent control of the charging current of the battery according to the actual situation of the battery to ensure the safety of the battery during charging.

If it is detected that the safe charging voltage is less than the input voltage, and/or, it is detected that the safe charging current is less than the input current, count the first duration that the safe charging voltage is less than the input voltage, and/or count the The safe charging current is less than the input current for a second duration.
在应用中,在确定安全充电电压与安全充电电流后,为保证电池的充电安全,终端设备可实时监测电池的输入电压与输入电流。具体的,对于终端设备为充电柜,充电柜可根据安全充电电压与安全充电电流,调整对电池进行充电的输入电压与输入电流。并在安全充电电压小于输入电压时,统计安全充电电压小于输入电压的第一持续时间,以及在安全充电电压小于输入电压时,统计安全充电电压小于输入电压的第二持续时间。在其他示例中,终端设备也可以为具有电池管理***的电池,对此不作限定。In the application, after determining the safe charging voltage and safe charging current, in order to ensure the charging safety of the battery, the terminal equipment can monitor the input voltage and input current of the battery in real time. Specifically, if the terminal device is a charging cabinet, the charging cabinet can adjust the input voltage and input current for charging the battery according to the safe charging voltage and safe charging current. When the safe charging voltage is less than the input voltage, count the first duration when the safe charging voltage is less than the input voltage, and count the second duration when the safe charging voltage is less than the input voltage when the safe charging voltage is less than the input voltage. In other examples, the terminal device may also be a battery with a battery management system, which is not limited.
S602、当所述第一持续时间和/或所述第二持续时间大于预设时间时,停止对所述电池进行充电。S602. When the first duration and/or the second duration is greater than a preset duration, stop charging the battery.
在应用中,上述预设时间可以为用户根据实际情况进行设定的时长,若第一持续时间和/或第二持续时间大于预设时间,则可确定输入电压持续高于安全充电电压,和/或,输入电流持续高于安全充电电流。然而,长时间的高输入电压或高输入电流将导致电池处于过充状态,造成电池温度的升高和电池内部的损坏。若终端设备为电池,则电池可进入自保护状态,主动断开与充电柜电路连接,并通过无线通信方式向充电柜提示充电过流报警,使其关闭电流和电压的输出。In an application, the above-mentioned preset time may be a time period set by the user according to the actual situation. If the first duration and/or the second duration are greater than the preset time, it may be determined that the input voltage is continuously higher than the safe charging voltage, and /or, the input current is continuously higher than the safe charging current. However, a high input voltage or high input current for a long time will cause the battery to be in an overcharged state, resulting in an increase in battery temperature and internal damage to the battery. If the terminal device is a battery, the battery can enter the self-protection state, actively disconnect the circuit connection with the charging cabinet, and prompt the charging overcurrent alarm to the charging cabinet through wireless communication, so that it can turn off the output of current and voltage.
