图1是本发明一个实施例的电动汽车动力电池温度控制方法的流程示意图。1 is a schematic flow chart of a method for controlling a temperature of a power battery of an electric vehicle according to an embodiment of the present invention.
如图1所示，该电动汽车动力电池温度控制方法包括：As shown in FIG. 1, the electric vehicle power battery temperature control method includes:
步骤101，在确定电动汽车处于静置状态时，获取电动汽车中动力电池单体电芯当前的温度值。In step 101, when it is determined that the electric vehicle is in a stationary state, the current temperature value of the battery cells of the power battery in the electric vehicle is obtained.
其中，本发明实施例提供的电动汽车动力电池温度控制方法，可以由本发明实施例提供的电动汽车动力电池温度控制装置，以下简称温度控制装置执行。其中，温度控制装置可以被配置在任意终端中，用于对电动汽车中动力电池的温度进行控制。其中，终端的类型有很多，比如可以是手机、电脑、电动汽车等。The electric vehicle power battery temperature control method provided by the embodiment of the present invention can be performed by the electric vehicle power battery temperature control device provided by the embodiment of the present invention, hereinafter referred to as the temperature control device. Wherein, the temperature control device can be configured in any terminal for controlling the temperature of the power battery in the electric vehicle. Among them, there are many types of terminals, such as mobile phones, computers, electric cars, and the like.
可以理解的是，在电动汽车处于上电状态时，动力电池在对外供电过程中，会发生化学反应而自动散热，使动力电池升温。因此，本发明实施例中，可以仅对电动汽车处于静置状态时，动力电池的温度进行控制。It can be understood that when the electric vehicle is in the power-on state, the power battery will spontaneously dissipate heat during the external power supply process, and the power battery will heat up. Therefore, in the embodiment of the present invention, the temperature of the power battery can be controlled only when the electric vehicle is in a resting state.
具体的，在确定电动汽车处于静置状态时，可以通过电动汽车中动力电池上安装的温度传感器，获取动力电池单体电芯当前的温度值。Specifically, when it is determined that the electric vehicle is in a stationary state, the current temperature value of the battery cells of the power battery can be obtained by using a temperature sensor installed on the power battery in the electric vehicle.
步骤102，在确定动力电池单体电芯当前的最低温度值低于加热温度阈值时，启动加热系统为动力电池进行加热处理。Step 102: When determining that the current minimum temperature value of the power battery cell is lower than the heating temperature threshold, the heating system is started to heat the power battery.
其中，动力电池的加热温度阈值，是根据动力电池的类型、属性等来确定。The heating temperature threshold of the power battery is determined according to the type, attribute, and the like of the power battery.
具体的，可以通过图2所示的动力电池加热电路，为动力电池进行加热处理。Specifically, the power battery can be heat-treated by the power battery heating circuit shown in FIG. 2.
具体实现时，若动力电池U单体电芯当前的最低温度值低于加热温度阈值，则温度控制装置可以控制定时开关K闭合，从而通过动力电池U内部的正温度系数热敏电阻(Positive  Temperature Coefficient，简称PTC)，对动力电池U进行加热，并在动力电池U的单体电芯最低温度上升到加热温度阈值时，控制定时开关K断开，从而实现对动力电池U的温度的控制。In the specific implementation, if the current minimum temperature value of the single cell of the power battery U is lower than the heating temperature threshold, the temperature control device can control the time switch K to be closed, thereby passing the positive temperature coefficient thermistor inside the power battery U (Positive Temperature) Coefficient (referred to as PTC) heats the power battery U, and when the minimum temperature of the single cell of the power battery U rises to the heating temperature threshold, the control timing switch K is turned off, thereby achieving control of the temperature of the power battery U.
可以理解的是，在实际运用中，温度控制装置可以配置在电脑或手机的远程监控平台中。若动力电池单体电芯当前的温度低于加热温度阈值，则远程监控平台可以向电动汽车中的车载信息终端(TelematicsBOX，简称TBOX)或远程监控系统(Remote Monitoring System，简称RMS)发送动力电池加热指令。TBOX或RMS接收到加热指令后，可以通过CAN网络，将加热指令发送给整车控制器(Vehicle Control Unit，简称VCU)，然后由VCU通过CAN网络发送给电池管理系统(Battery Management System，简称BMS)，从而由BMS控制对动力电池的加热处理。It can be understood that in actual use, the temperature control device can be configured in a remote monitoring platform of a computer or a mobile phone. If the current temperature of the power battery cell is lower than the heating temperature threshold, the remote monitoring platform can send the power battery to the telematics terminal (TBOX) or the remote monitoring system (RMS) in the electric vehicle. Heating instruction. After the TBOX or RMS receives the heating command, the heating command can be sent to the vehicle control unit (VCU) through the CAN network, and then sent by the VCU to the battery management system (Battery Management System, BMS for short) through the CAN network. ), whereby the heat treatment of the power battery is controlled by the BMS.
本发明实施例提供的电动汽车动力电池温度控制方法，首先在确定电动汽车处于静置状态时，获取电动汽车中动力电池单体电芯当前的温度值，然后在确定动力电池单体电芯当前的最低温度值低于加热温度阈值时，启动加热系统为动力电池进行加热处理。由此，实现了在电动汽车处于静置状态时，对电动汽车中动力电池的温度进行控制，解决了电动汽车在长时间处于静置状态下，动力电池单体电芯的最低温度低于加热温度阈值时，无法及时进入慢充充电阶段，也无法启动快充充电的问题，避免了环境温度较低对动力电池的影响，延长了动力电池的使用寿命，改善了用户体验。The method for controlling the temperature of a power battery of an electric vehicle according to an embodiment of the present invention firstly obtains a current temperature value of a battery cell of a power battery in an electric vehicle when determining that the electric vehicle is in a stationary state, and then determines a current battery cell of the power battery. When the lowest temperature value is lower than the heating temperature threshold, the heating system is activated to heat the power battery. Therefore, when the electric vehicle is in a static state, the temperature of the power battery in the electric vehicle is controlled, and the minimum temperature of the power battery cell is lower than the heating when the electric vehicle is in a standing state for a long time. When the temperature threshold is reached, it is impossible to enter the slow charging and charging phase in time, and the problem of fast charging and charging cannot be started, and the influence of low ambient temperature on the power battery is avoided, the service life of the power battery is prolonged, and the user experience is improved.
通过上述分析可知，在确定电动汽车处于静置状态时，可以在动力电池单体电芯当前的最低温度值低于加热温度阈值时，启动加热系统为动力电池进行加热处理。在实际运用中，动力电池当前的剩余电量值可能很低，为避免电量的过快消耗，在本发明一种可能的实现形式中，还可以结合动力电池当前的剩余电量值，对动力电池的温度进行控制，下面结合图3，对本发明实施例提供的电动汽车动力电池温度控制方法进行进一步说明。According to the above analysis, when it is determined that the electric vehicle is in a stationary state, the heating system can be started to heat the power battery when the current minimum temperature value of the power battery cell is lower than the heating temperature threshold. In actual use, the current residual power value of the power battery may be very low. In order to avoid excessive consumption of power, in a possible implementation form of the present invention, the current remaining power value of the power battery may also be combined with the power battery. The temperature is controlled. The method for controlling the temperature of the electric vehicle power battery provided by the embodiment of the present invention is further described below with reference to FIG. 3 .
图3是本发明另一个实施例的电动汽车动力电池温度控制方法的流程示意图。3 is a flow chart showing a method for controlling a temperature of a power battery of an electric vehicle according to another embodiment of the present invention.
如图3所示，该电动汽车动力电池温度控制方法包括：As shown in FIG. 3, the electric vehicle power battery temperature control method includes:
步骤201，在确定电动汽车处于静置状态时，获取电动汽车中动力电池单体电芯当前的温度值。In step 201, when it is determined that the electric vehicle is in a stationary state, the current temperature value of the battery cells of the power battery in the electric vehicle is obtained.
步骤202，在确定动力电池单体电芯当前的最低温度值低于加热温度阈值时，确定动力电池当前的剩余电量值是否大于第一阈值，若是，则执行步骤203，否则，执行步骤204。Step 202: Determine whether the current remaining battery value of the power battery is greater than the first threshold when determining that the current minimum temperature value of the power battery cell is lower than the heating temperature threshold. If yes, execute step 203; otherwise, perform step 204.
步骤203，启动加热系统为动力电池进行加热处理。In step 203, the heating system is activated to heat the power battery.
步骤204，停止执行获取动力电池单体电芯当前的温度值的操作。In step 204, the operation of acquiring the current temperature value of the power battery cell is stopped.
其中，第一阈值，可以根据需要确定，比如，可以根据经验确定，也可以根据动力电 池的类型、属性等确定，等等。The first threshold may be determined according to requirements, for example, may be determined according to experience, may be determined according to the type and attribute of the power battery, and the like.
具体的，若动力电池当前的剩余电量值大于第一阈值，则可以启动加热系统为动力电池进行加热处理；若动力电池当前的剩余电量值小于或等于第一阈值，可以停止执行获取电动汽车中动力电池单体电芯当前的温度值的操作，以避免动力电池电量的过快消耗。Specifically, if the current remaining power value of the power battery is greater than the first threshold, the heating system may be started to perform heating processing on the power battery; if the current remaining power value of the power battery is less than or equal to the first threshold, the execution of the electric vehicle may be stopped. The operation of the current temperature value of the battery cell of the power battery to avoid excessive consumption of the power battery.
可以理解的是，在本发明实施例中，对电动汽车的动力电池进行加热处理后，若动力电池仍然处于静置状态，则动力电池单体电芯的最低温度可能会再次降低至低于加热温度阈值。在本发明实施例中，可以以一定的时间间隔，获取电动汽车中动力电池单体电芯当前的温度值，从而在确定动力电池单体电芯当前的最低温度值低于加热温度阈值时，启动加热系统为动力电池进行加热处理。即，步骤201中，获取电动汽车中动力电池单体电芯当前的温度值，可以包括：It can be understood that, in the embodiment of the present invention, after the power battery of the electric vehicle is heated, if the power battery is still in a resting state, the lowest temperature of the battery cells of the power battery may be lowered again to be lower than the heating. Temperature threshold. In the embodiment of the present invention, the current temperature value of the power battery cell in the electric vehicle can be obtained at a certain time interval, so that when the current minimum temperature value of the power battery cell is determined to be lower than the heating temperature threshold, The heating system is activated to heat the power battery. That is, in step 201, obtaining the current temperature value of the power battery cell in the electric vehicle may include:
获取动力电池当前的剩余电量值；Obtaining the current remaining battery value of the power battery;
根据当前的剩余电量值，确定检测动力电池单体电芯当前的温度值的时间间隔；Determining, according to the current remaining power value, a time interval for detecting a current temperature value of the battery cells of the power battery;
以时间间隔为触发条件，触发执行获取动力电池单体电芯的温度值的操作。The operation of acquiring the temperature value of the battery cell of the power battery is triggered by the time interval being the trigger condition.
具体的，可以预先设置动力电池当前的剩余电量值，与检测动力电池单体电芯当前的温度值的时间间隔的对应关系，从而在获取动力电池当前的剩余电量值后，可以根据预设的对应关系，确定检测动力电池单体电芯当前的温度值的时间间隔，从而以时间间隔为触发条件，触发执行获取动力电池单体电芯的温度值的操作。Specifically, the corresponding relationship between the current remaining power value of the power battery and the time interval for detecting the current temperature value of the power battery cells may be preset, so that after obtaining the current remaining power value of the power battery, the preset Corresponding relationship, determining a time interval for detecting a current temperature value of the battery cell of the power battery, thereby triggering an operation of acquiring a temperature value of the battery cell of the power battery with the time interval as a trigger condition.
举例来说，假设第一阈值为动力电池容量值的20％，可以预先设置动力电池的剩余电量值SOC为20％<SOC<30％时，检测动力电池单体电芯当前的温度值的时间间隔为5小时；动力电池的剩余电量值SOC为SOC>＝30％时，检测动力电池单体电芯当前的温度值的时间间隔为3小时。若获取到动力电池当前的剩余电量值为动力电池容量值的25％，则可以以5小时的时间间隔，检测电动汽车中动力电池单体电芯当前的温度值，进而根据动力电池单体电芯当前的温度值，对动力电池进行温度控制。For example, if the first threshold is 20% of the power battery capacity value, the time when the current battery value of the power battery cell is detected may be preset when the remaining battery power value SOC of the power battery is 20% < SOC < 30%. The interval is 5 hours; when the remaining battery value SOC of the power battery is SOC>=30%, the time interval for detecting the current temperature value of the battery cells of the power battery is 3 hours. If the current remaining battery value of the power battery is 25% of the power battery capacity value, the current temperature value of the power battery cell in the electric vehicle can be detected at a time interval of 5 hours, and then according to the power battery unit The current temperature value of the core controls the temperature of the power battery.
需要说明的是，在本发明实施例中，还可以结合动力电池箱的保温效果、电动汽车所处的环境温度等因素，确定检测动力电池单体电芯当前的温度值的时间间隔，从而以时间间隔为触发条件，触发执行获取动力电池单体电芯的温度值的操作，进而根据动力电池单体电芯当前的温度值，对动力电池进行温度控制。It should be noted that, in the embodiment of the present invention, the time interval between detecting the current temperature value of the battery cells of the power battery may be determined by combining the thermal insulation effect of the power battery box and the ambient temperature of the electric vehicle, thereby The time interval is a trigger condition, triggering an operation of acquiring a temperature value of the power battery cell, and then controlling the temperature of the power battery according to the current temperature value of the battery cell.
值得注意的是，在本发明实施例中，电动汽车处于静置状态时，是否执行获取动力电池单体电芯当前的温度值的操作，还可以由用户控制。即，在本发明实施例中，还可以包括：It should be noted that, in the embodiment of the present invention, when the electric vehicle is in a resting state, whether to perform the operation of acquiring the current temperature value of the battery cells of the power battery is also controlled by the user. That is, in the embodiment of the present invention, the method may further include:
根据用户的操作，停止执行获取动力电池单体电芯当前的温度值的操作。According to the user's operation, the operation of acquiring the current temperature value of the power battery cell is stopped.
其中，用户的操作，可以是用户通过点击、滑动或长按具有控制获取动力电池单体电 芯当前的温度值功能的按钮触发的，此处不作限制。The user's operation may be triggered by the user clicking, sliding or long pressing a button having the function of controlling the current temperature value of the power battery cell, which is not limited herein.
