- Fig. 4 is a schematic flowchart of a charging control method provided by an embodiment of the present invention, the method is applied to a charging device, and the charging device is used to charge an electric vehicle.
- This method can be carried out by the charging device shown in Figure 1, Figure 2 or Figure 3, as shown in Figure 4, the method includes:
- Step 401 Obtain the charging current of the battery of the electric vehicle during the charging process.
- the charging device as shown in Figure 2 or Figure 3 includes a CP detection module 201, before obtaining the charging current of the battery of the electric vehicle during the charging process, the CP detection module 201 can be used to detect whether There is a charging cable plugged into the charging port of the electric vehicle.
- step 401 does not need to be performed, and only when the CP detection module 201 detects that the charging gun has been inserted into the charging interface of the electric vehicle does step 401 start to be executed, which can Improve the accuracy of detection.
- Step 402 Based on the charging current of the battery and the corresponding relationship between the charging current and the data value of the battery's power, the data value of the battery's power is acquired.
- the corresponding relationship between the charging current and the battery power data value can be obtained in the following manner. First, the data information of the electric vehicle is obtained, and then, the correspondence between the charging current and the battery power data value can be obtained according to the data signal relation.
- the data information of the electric vehicle may include the model and production year of the electric vehicle; the power data value may be the SOC value, or the remaining power value of the battery.
- the corresponding relationship between the charging current and the SOC value can also be called the mapping relationship between the charging current and the SOC value, that is, there is a one-to-one correspondence between the charging current and the SOC value. Then, for the data For an electric vehicle with the same information, its charging current and SOC value can be fitted into a curve.
- mapping data can be collected according to the mapping data between the charging current and the SOC value of batteries of different car series and years of electric vehicles, and then data fitting can be carried out according to the batteries of different car series and years to fit a

- the database is stored in the charging device in advance.
- the charging device only needs to obtain the charging current and the data information of the electric vehicle, then it can find the charging current-SOC value mapping table corresponding to the battery of the electric vehicle, and then substitute the charging current into the charging current-SOC value mapping table , the SOC value of the current battery can be obtained directly.
- the charging device includes a display module 210 as shown in FIG.
- the battery has been charged to a specific power level, and the approximate time point at which the charging process ends can be known, which is helpful for the user to better arrange his own time, that is, it provides convenience for the user.
- Step 403 Control the charging process of the battery based on the power data value.
- the power data value mainly refers to the current power value of the battery, which can be reflected by the SOC value or the remaining power of the battery. If the charging device can know the power data value of the battery of the electric vehicle, then the electric vehicle can know how much power the battery has been charged according to the power data value obtained in real time, and then, the charging process can be ended in time when the battery power is full, so as to prevent The service life of the battery is affected by overcharging.

- the power data value as an SOC value as an example.
- the charging mode is the healthy mode
- the charging process of the battery is ended.
- the first preset threshold is less than 1. Since the SOC value is a ratio less than or equal to 1, that is to say, the maximum value of the SOC value is 1, at this time, setting the first preset threshold value to be less than 1 is to control the SOC value of the battery from reaching 1 during the charging process, that is, The battery will not reach full charge. This is because the rechargeable battery is usually a lithium battery, and the physical characteristics of the lithium battery determine that shallow charging and shallow discharging (that is, full charging) can get a longer battery life, so the control stops when the SOC value is less than 1.

为了便于理解本申请,首先介绍下本申请可以适用的应用场景,请参照图1。图1为本申请实施例提供的充电控制方法的一种应用场景,在该场景中包括电动车辆10与充电桩20。
如图1所示,在电动汽车10中设置有BMS11(BMS全称为电池管理***)与动力电池12(例如,锂电池),其中,BMS11为一套保护动力电池12使用安全的控制***,时刻监控动力电池12的使用状态。充电桩20用于对锂电池12进行充电,该充电过程需要受到BMS11的控制。因此,在充电过程中,BMS11能够控制充电桩20对动力电池12进行充电的方式,比如,恒流充电方式或变电流充电方式。同时,BMS11还能够控制充电桩11对动力电池12进行充电的充电电流大小以及读取动力电池12的参数变化情况。

示例性的,请参照图2,为一种可能的充电装置的硬件结构示意图,该充电装置可用于执行本申请实施例提供的充电控制方法。
如图2所示,该充电装置包括CP检测模块201与控制模块202,其中,在充电装置中,控制导引(Control Pilot,CP)信号为检测充电装置是否与电动车辆连接的信号,所以CP检测模块201可用于检测是否有充电枪***电动车辆的充电接口,其中,若检测到未有充电器***电动车辆的充电接口,此时可能是充电器从充电接口上拔出,也可以是还未***充电接口。
控制模块202与CP检测模块201连接,在CP检测模块201检测到有充电枪***电动车辆的充电接口时,控制模块202能够通过CP检测模块201得知有充电枪***充电接口,从而,控制模块202可进一步控制电动车辆的电池的充电过程,例如,在控制模块202得知有充电器***电动车辆的充电接口,即控制电池的充电过程开始。
其中,控制模块202可以采用微控制单元(Microcontroller Unit,MCU)或者数字信号处理(Digital Signal Processing,DSP)控制器等。
控制模块202包括至少一个处理器2021以及存储器2022,其中,存储器2022可以内置在控制模块202中,也可以外置在控制模块202外部,存储器2022还可以是远程设置的存储器,通过网络连接所述控制模块202。

处理器2021可以为一个或多个,图1中以一个处理器2021为例。处理器2021和存储器2022可以通过总线或者其他方式连接。处理器2021可包括中央处理单元(CPU)、数字信号处理器(DSP)、专用集成电路(ASIC)、控制器、现场可编程门阵列(FPGA)设备等。处理器2021还可以被实现为计算设备的组合,例如,DSP与微处理器的组合、多个微处理器、结合DSP核心的一个或多个微处理器、或者任何其它此类配置。
需要说明的是,如图2所示的充电装置的硬件结构仅是一个示例,并且,充电装置可以具有比图中所示出的更多的或者更少的部件,可以组合两个或更多的部件,或者可以具有不同的部件配置,图中所示出的各种部件可以在包括一个或多个信号处理和/或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。

其中,控制模块202通过通信模块203以通过WIFI、蓝牙、4G或CAN等通信方式与服务器、智能终端(例如手机)或电动汽车等进行数据通信。例如,控制模块202通过通信模块203与手机通信,则手机可从控制模块207接收到当前电池的充电电流等数据。
电能计量及计费模块204根据所检测到的电池的充电电流,并采用安时积分法,即在预设时长内对充电电流进行积分,可获得预设时长内对充入电动车辆的电能的计量。进而,该电能计量及计费模块204可根据收费标准与充入电动车辆的电能的计量,确定应收取的费用。
存储模块205能够对充电过程中的相关数据(例如充电电流)等进行存储,还能够存储预设设置的充电电流与电量数据值(例如SOC值(State of Charge),电池荷电状态值,又称为剩余电量)之间的映射关系等。

因此,充电装置既可实现与外部设备进行数据的通信与交互,也可实现对充电过程的参数的控制,还可实现对电动车辆的电池相关数据的显示,并能够实现对电量的计费与收费。
在一实施例中,充电装置为充电桩,在充电桩上设置有充电枪,通过将充电枪***电动车辆的充电接口中,可为电动车辆的电池进行充电,同时,充电桩可控制电池的控制过程。
图4为本发明实施例提供的充电控制方法的流程示意图,该方法应用于充电装置,充电装置用于为电动车辆充电。该方法可以由图1、图2或图3所示的充电装置执行,如图4所示,该方法包括:
步骤401:获取电动车辆的电池在充电过程中的充电电流。
在一实施例中,若充电装置如图2或图3所示,包括CP检测模块201,则在获取电动车辆的电池在充电过程中的充电电流之前,可先用过CP检测模块201检测是否有充电枪***电动车辆的充电接口。
继而,如果CP检测模块201未检测到有充电枪***电动车辆的充电接口,则无需执行步骤401,只有在CP检测模块201检测到充电枪已***电动车辆的充电接口才开始执行步骤401,能够提高检测的准确度。
步骤402:基于电池的充电电流、以及充电电流与电池的电量数据值的对应关系,获取电池的电量数据值。
在一实施例中,可通过以下方式获得充电电流与电池的电量数据值的对应关系,首先,获得电动车辆的数据信息,继而,根据该数据信号可获得充电电流与电池的电量数据值的对应关系。其中,电动车辆的数据信息可以包括电动车辆的车系与生产年份;电量数据值可以为SOC值,也可以为电池的剩余电量值。
以电量数据值为SOC值为例,充电电流与SOC值的对应关系也可以称之为充电电流与SOC值之间的映射关系,即充电电流与SOC值之间一一对应,那么,对于数据信息相同的电动车辆,其充电电流与SOC值可以拟合为一条曲线。
具体地,可先按照不同车系和不同年份电动车的电池的充电电流与SOC值之间的映射数据进行大量搜集,然后根据不同车系、不同年份的电池进行数据拟合,拟合出一条动力电池的充电电流-SOC值曲线,保证该曲线符合该车系与该年份的电池的整体充电电流-SOC值变化曲线。如此一来,针对不同车系,不同年份的动力电池都存在一条充电电流-SOC值曲线即电流-SOC值映射 表,从而,可形成了一个充电电流-SOC值映射数据库。最后,再将该数据库提前存入充电装置中。
可见,充电装置只需获取到充电电流与电动车辆的数据信息,那么就能够找到与该电动车辆的电池对应的充电电流-SOC值映射表,再将充电电流代入充电电流-SOC值映射表中,则可以直接得到当前电池的SOC值。
进一步地,如果充电装置包括如图3所示的显示模块210,那么在获取到电池的电量数据值之后,可将电量数据值显示于显示模块210上,从而,用户能够通过显示模块210得知电池具体已充电至多少电量值,且也就能够知道充电过程结束的大概时间点,有利于用户更好的安排好自己的时间,即为用户提供了便利。
步骤403:基于电量数据值控制电池的充电过程。
其中,电量数据值主要指电池当前的电量值,其可以通过SOC值或至电池剩余电量体现。如果充电装置能够获知电动车辆的电池的电量数据值,那么电动车辆就能够根据实时获得的电量数据值得知电池已充入多少电量,继而,可在电池的电量充满时及时结束充电过程,以防止电池因过充而影响其使用寿命。
在一实施例中,还进一步获取电动车辆所需的充电模式,并结合电动车辆的充电模式与电量数据值控制电池的充电过程,其中,电动车辆的充电模式可包括健康模式与普通模式。
具体地,以电量数据值为SOC值为例进行说明。
如果充电模式为健康模式,那么当SOC值大于或等于第一预设阈值的时候就结束电池的充电过程。其中,第一预设阈值小于1。由于SOC值为一个小于或等于1的比值,也就是说SOC值最大值为1,此时,设置第一预设阈值小于1是为了控制电池在充电过程中SOC值不会达到1,也就是电池不会达到满充状态。这是因为,通常充电电池为锂电池,而锂电池的物理特性决定了电量浅充浅放(即不满放满充)能够得到更长的电池寿命,所以控制在SOC值不到1时即停止充电过程,能够延长电池的使用寿命。例如,将第一预设阈值设置为80%,则在健康模式下,当充电装置检测到电池的SOC值已经为大于或等于80%了,即断开电池的充电过程,不再为电池充电。
如果充电模式为普通模式,则当电池的SOC值大于或等于1时,才结束电池的充电过程。在该种模式下,只有当充电装置检测到电池的SOC值为100%了,才会断开电池的充电过程,停止为电池充电。此时,电池的电量为满电量,能够满足用户更长时间的使用。
因此,当用户需要在一段较长的时间内连续使用电动车辆,可设置充电模式为普通模式以满足需求,而在日常的使用过程中,例如该电动车辆用于短途的上下班,则可将充电模式设置为健康模式,以延长电池的使用寿命。
综上,在本申请中,首先,利用大量搜集的充电电流与SOC的对应关系数据拟合出充电电流与电量数据值的映射表。继而,可根据检测到的充电电流与 电动车辆的数据信息,从充电电流与电量数据值的映射表找到对应的电量数据值,并将该电量数据值通过充电装置的显示模块进行显示,以为用户带来便利,提升用户体验。最后,再根据电量数据值控制电池的充电过程,不仅能够及时停止电池的充电过程,以防止过充对电池造成的损害,还能够通过采用健康模式进行充电,以延长电池的使用寿命。
图5是本发明实施例提供一种充电控制装置的结构示意图。如图5所示,充电控制装置500包括第一获取单元501、第二获取单元502与充电过程控制单元503。
第一获取单元501用于获取电动车辆的电池在充电过程中的充电电流。第二获取单元502用于基于电池的充电电流、以及充电电流与电池的电量数据值的对应关系,获取电池的电量数据值。充电过程控制单元503用于基于电量数据值控制电池的充电过程。
