本发明属于对车辆供电的电池领域,尤其涉及一种车辆用电池加热控制系统及其控制方法。The invention belongs to the field of batteries for powering vehicles, and in particular relates to a vehicle battery heating control system and a control method thereof.
背景技术Background technique
目前,混合动力车和电动车的能量来源主要是车上的动力电池组,动力电池组一般采用的是锂电池,锂电池已经成为便携式电子设备及电动车所使用的理想电源。考虑到汽车需要在复杂的路况和环境条件下行驶,或者有些电子设备需要在较差的环境条件中使用,所以作为电动车或电子设备电源的电池就需要适应这些复杂的状况,尤其是当电动车或电子设备处于低温环境中时,更需要电池具有优异的低温充放电性能和较高的输出、输入功率性能。电池在低温环境下时,电池的活性降低,无法正常工作。目前通常做法是利用这些电池内部的电化学反应来改善电池低温性能或者在电池外部设置加热装置来提高电池整体温度而使电池在适宜的温度下工作。At present, the energy source of hybrid vehicles and electric vehicles is mainly the power battery pack on the vehicle. The power battery pack generally uses lithium batteries. Lithium batteries have become ideal power sources for portable electronic devices and electric vehicles. Considering that the car needs to drive under complex road conditions and environmental conditions, or some electronic equipment needs to be used in poor environmental conditions, the battery used as the power supply of electric vehicles or electronic equipment needs to adapt to these complex conditions, especially when electric When the vehicle or electronic equipment is in a low-temperature environment, the battery needs to have excellent low-temperature charge and discharge performance and high output and input power performance. When the battery is in a low temperature environment, the activity of the battery is reduced and it cannot work normally. The current common practice is to use the electrochemical reactions inside these batteries to improve the low-temperature performance of the batteries or to install a heating device outside the batteries to increase the overall temperature of the batteries so that the batteries can work at a suitable temperature.
就在电池外部设置加热装置的方式来说,现有的方案大多是通过检测电池的温度来启动或停止对电池的加热,一般来说,当温度低于某一预定温度时开始对电池进行加热,并当温度达到另一预定温度时停止对电池进行加热。As far as the heating device is installed outside the battery, most of the existing solutions start or stop heating the battery by detecting the temperature of the battery. Generally speaking, when the temperature is lower than a predetermined temperature, the battery starts to be heated. , and stop heating the battery when the temperature reaches another predetermined temperature.
例如,现有中的一种电池包温控系统,运用于一便携式电子装置内,该系统包括:一温度感测单元,设置于一电池包之内,用以持续感测该电池包的一内部温度;一温度控制单元,设置于该便携式电子装置中,用以设定一低温加热温度,并接收该内部温度,确认该内部温度小于该低温加热温度时,产生一低温加热信号;及一热能产生单元,设置于该电池包之内,用以接收该低温加热信号,并产生一热能至该电池包之中。For example, an existing temperature control system for a battery pack is used in a portable electronic device. The system includes: a temperature sensing unit disposed in a battery pack for continuously sensing a temperature of the battery pack. Internal temperature; a temperature control unit, installed in the portable electronic device, is used to set a low-temperature heating temperature, and receive the internal temperature, and generate a low-temperature heating signal when the internal temperature is confirmed to be lower than the low-temperature heating temperature; and a The thermal energy generating unit is arranged in the battery pack to receive the low-temperature heating signal and generate heat energy into the battery pack.
现有的电池加热控制系统都是通过在电池组外部增设一个加热装置来改善电池组的温度,通过检测电池的温度来启动或停止对电池的加热,一般来说,当电池的温度低于某一预定温度时开始对电池进行加热,并当温度达到另一预定温度时停止对电池进行加热。由于电池的温度是从内部集流体扩展至其他部位,温度在短时间内很难趋于平稳,这种仅利用单一的电池温度条件来控制何时启动和停止加热并不十分符合实际需要,对于实际运用而言并不能够很好的保护电池。The existing battery heating control system improves the temperature of the battery pack by adding a heating device outside the battery pack, and starts or stops heating the battery by detecting the temperature of the battery. Generally speaking, when the temperature of the battery is lower than a certain Heating the battery starts at a predetermined temperature and stops heating the battery when the temperature reaches another predetermined temperature. Since the temperature of the battery extends from the internal current collector to other parts, it is difficult to stabilize the temperature in a short period of time. It is not very practical to use only a single battery temperature condition to control when to start and stop heating. For In actual use, it can't protect the battery very well.

Compared with the single battery temperature judgment method used in the prior art to start heating, more factors are considered for diversification. Since the heating of the battery is started only when the ambient temperature of the system, the battery temperature and the battery capacity are satisfied at the same time, the battery in the low-temperature environment can be effectively heated up, and at the same time, the entire system can be kept from being falsely triggered. The charging and discharging performance of the battery is improved, and it will not cause damage to the battery, prolonging the life of the battery and reducing the power consumption of the system.

所述加热控制模块1,根据所述环境温度比较单元3的比较信号控制其自身的上电或断电。The heating control module 1 controls its own power-on or power-off according to the comparison signal of the ambient temperature comparison unit 3 .
只有在加热控制模块1上电的情况下,加热控制模块1内部的单元才能正常运行,才能根据相应的条件控制电池加热单元2对电池进行加热。Only when the heating control module 1 is powered on, the units inside the heating control module 1 can operate normally, and the battery heating unit 2 can be controlled to heat the battery according to corresponding conditions.
其中,图3为本发明中一种实施例环境温度比较单元3的电路图,所述环境温度比较单元3包括比较器U19A,比较器U19A的同相输入端分别与电阻R69和电阻R68的一端连接,电阻R69的另一端与12V电源连接,电阻R68的另一端和比较器U19A电源负极分别与地连接,电阻R69与电阻R68的阻值相等作为比较的基准电阻,比较器U19A的反相输入端分别与恒温电阻R77和热敏电阻R76的一端连接,恒温电阻R77的另一端和比较器U19A电源正极分别与12V电源连接,热敏电阻R76的另一端与地连接,比较器U19A的输出端输出一个电平信号,作为驱动加热控制模块1的上电或断电的信号。Wherein, Fig. 3 is a circuit diagram of an embodiment of the ambient temperature comparison unit 3 in the present invention, the ambient temperature comparison unit 3 includes a comparator U19A, and the non-inverting input terminal of the comparator U19A is respectively connected to one end of a resistor R69 and a resistor R68, The other end of the resistor R69 is connected to the 12V power supply, the other end of the resistor R68 and the negative pole of the comparator U19A power supply are respectively connected to the ground, the resistance values of the resistor R69 and the resistor R68 are equal to each other as a reference resistor for comparison, and the inverting input terminals of the comparator U19A are respectively Connect with one end of the constant temperature resistor R77 and thermistor R76, the other end of the constant temperature resistor R77 and the positive pole of the comparator U19A power supply are respectively connected with the 12V power supply, the other end of the thermistor R76 is connected with the ground, and the output terminal of the comparator U19A outputs a The level signal is used as a signal to drive the heating control module 1 to power on or off.
所述环境温度比较单元3的工作原理如下:当系统上电后,环境温度监控单元的基准电压为正极电压U19A+,环境温度监控单元的比较电压为负极电压U19A-。当环境温度等于温度设定值K1时,恒温电阻R77的阻值与热敏电阻R76的阻值相等,(U19A+)=(U19A-),比较器U19A输出低电平信号,即输出供电允许信号T-OFF给加热控制模块1,热控制模块1上电,系统进入工作模式。当环境温度大于温度设定值K1时,(U19A+)>(U19A-),U19A输出高电平,即输出供电非允许信号T-OFF给加热控制模块1,使热控制模块1断电,系统进入休眠模式。当环境温度低于温度设定值K1时,(U19A+)<(U19A-),比较器U19A输出低电平信号,即输出供电允许信号T-OFF给加热控制模块1,使热控制模块1上电,系统进入工作模式。通过环境温度比较单元3保证系统在环境温度高于温度设定值K1时,加热控制模块1被断电,不会被误触发而使电池加热单元2工作,同时降低系统的功耗,也不会在环境温度高时,对电池加热以致于使电池损坏。The operating principle of the ambient temperature comparison unit 3 is as follows: when the system is powered on, the reference voltage of the ambient temperature monitoring unit is the positive voltage U19A+, and the comparison voltage of the ambient temperature monitoring unit is the negative voltage U19A-. When the ambient temperature is equal to the temperature setting value K1, the resistance value of the constant temperature resistor R77 is equal to the resistance value of the thermistor R76, (U19A+)=(U19A-), the comparator U19A outputs a low level signal, that is, the output power supply permission signal T-OFF powers the heating control module 1, powers on the heating control module 1, and the system enters the working mode. When the ambient temperature is higher than the temperature setting value K1, (U19A+)>(U19A-), U19A outputs a high level, that is, outputs a power supply non-permission signal T-OFF to the heating control module 1, so that the thermal control module 1 is powered off, and the system Enter hibernation mode. When the ambient temperature is lower than the temperature setting value K1, (U19A+)<(U19A-), the comparator U19A outputs a low-level signal, that is, outputs the power supply permission signal T-OFF to the heating control module 1, so that the heating control module 1 Power on, the system enters the working mode. The ambient temperature comparison unit 3 ensures that when the ambient temperature of the system is higher than the temperature setting value K1, the heating control module 1 is powered off, and the battery heating unit 2 will not be triggered by mistake, and the power consumption of the system will be reduced at the same time. When the ambient temperature is high, the battery will be heated to damage the battery.
作为进一步改进,所述加热控制系统还包括用于对系统运行时间进行计时的第一计时单元4,所述第一计时单元4与所述加热控制模块1电连接。加热控制模块1启动时,第一计时单元4开始工作,对系统运行时间进行计时使系统的最大运行时间不超过一定值T1,以防止系统运行紊乱时进入死循环而发送持续有效的加热信号给电池加热单元2,在第一计时单元4的计时时间达到一定值T1时,能使加热控制模块1断电,系统进入休眠模式。As a further improvement, the heating control system further includes a first timing unit 4 for timing the running time of the system, and the first timing unit 4 is electrically connected to the heating control module 1 . When the heating control module 1 starts, the first timing unit 4 starts to work, timing the system running time so that the maximum running time of the system does not exceed a certain value T1, so as to prevent the system from entering an endless loop when the system is running in disorder and sending a continuous and effective heating signal to The battery heating unit 2 can power off the heating control module 1 when the timing time of the first timing unit 4 reaches a certain value T1, and the system enters a sleep mode.

Preferably, an IGBT module with a withstand voltage of more than 1000V, more preferably 1200V is usually selected.

在本发明中,脉冲发生器根据控制单元11的控制信号生成脉冲序列并输出到开关模块的控制端来控制开关模块的启动和停止。同样,为了避免长时间短路对电池造成不必要的损害,需要对开关模块的导通和断开的时间有一定的限制。优选情况下,脉冲发生器生成的脉冲序列的脉宽一般为1-3ms,优选为1-2ms,占空比为5-30%,优选为5-10%,持续时间为30-最大加热时间T2max,优选为60-360s。In the present invention, the pulse generator generates a pulse sequence according to the control signal of the control unit 11 and outputs it to the control terminal of the switch module to control the start and stop of the switch module.

步骤S08,电池加热时间T电是否大于时间设定值T2,如果是,则进入步骤S09,如果判断结果为否,则系统进入步骤S07,继续计时;Step S08, whether thebattery heating time T is greater than the time setting value T2, if yes, then enter step S09, if the judgment result is no, then the system enters step S07, and continues timing;
步骤S09,控制单元11控制电池加热单元2停止对电池进行加热,系统进入步骤S02,程序结束。In step S09, the control unit 11 controls the battery heating unit 2 to stop heating the battery, the system enters step S02, and the program ends.
对于步骤S01中,所述温度设定值K1的取值范围为:-10℃到10℃。For step S01, the temperature setting value K1 ranges from -10°C to 10°C.
对于步骤S05和步骤S08,系统运行时间的设定值T1的取值范围为:T2<T1<300s,保证满足加热控制模块1控制电池加热单元2对电池的加热时间,同时防止加热控制模块1进入死循环时超时运行,电池加热时间的设定值T2的取值范围为:10s到240s。For steps S05 and S08, the value range of the set value T1 of the system running time is: T2<T1<300s, ensuring that the heating control module 1 controls the heating time of the battery heating unit 2 for the battery, and at the same time prevents the heating control module 1 When it enters an infinite loop, it runs overtime, and the set value T2 of the battery heating time ranges from 10s to 240s.

The SOC of the battery refers to the ratio of the actual power of the battery to the power when it is fully charged, which is a percentage and is estimated by various conventional methods in actual operation. When the battery state of charge SOC is too low, the system controls battery short-circuit heating to have a great impact on the service life of the battery, so the value range of the battery state of charge set value SOC1 is: 30% to 50%.
