Embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Fig. 1 shows the functional-block diagram of battery thermal management control system described in the utility model, as shown in Figure 1, described battery thermal management control system comprises entire car controller 1(VCU, Vehicle Control Unit), battery manager 2(BMS, Battery Management System), evaporator electromagnetically operated valve 6 and evaporator using for air electromagnetically operated valve 7 for air-conditioner controller 3, battery blower fan 9, heating module, the first Temperature Detector 41, the second Temperature Detector 42, battery.
Particularly, entire car controller 1 is electrically connected with battery manager 2 and air-conditioner controller 3 respectively by CAN bus.Battery blower fan 9, the first Temperature Detector 41, the second Temperature Detector 42 and heating module are all electrically connected with battery manager 2.For battery, evaporator electromagnetically operated valve 6, evaporator using for air electromagnetically operated valve 7 and compressor of air conditioner 8 are electrically connected with air-conditioner controller 3 respectively.The output of described compressor of air conditioner 8 is sequentially connected by evaporator and evaporator using for air with battery by pipeline, and battery is with evaporator for cooling power battery pack, and evaporator using for air is for cooling automobile passenger cabin.
Heating module is used for heating power battery pack, and in a preferred embodiment of the present utility model, described heating module is preferably ptc heater 5.The first Temperature Detector 41 is for detection of the temperature of cell in power battery pack, and the second Temperature Detector 42 is the temperature with evaporator for detection of battery.Described the first Temperature Detector 41 is arranged on the outer surface of cell in described power battery pack, and described the second Temperature Detector 42 is arranged on the exit of described battery evaporator
The operation principle of battery thermal management control system described in the utility model is:
When car load is in charge mode (when charging plug connects power supply and onboard charger, entire car controller can receive charging wake-up signal, car load is in charge mode,) or discharge mode (when ignition switch is opened and charging plug does not connect power supply and onboard charger, car load is in discharge mode) under, the first Temperature Detector 41 and the second Temperature Detector 42 offer battery manager 2 by the temperature of cell in the power battery pack detecting and battery by the temperature of evaporator in real time respectively, entire car controller 1 by and battery manager 2 between CAN communication obtain the temperature of cell in power battery pack, when the temperature of at least two cells is during simultaneously for example, higher than first threshold (40 ℃), system enters heat management pattern and freezes to power battery pack: first entire car controller 1 is opened battery blower fan 9 by battery manager 2, then for example, after very first time section (30s), entire car controller 1 is opened battery evaporator electromagnetically operated valve 6 by air-conditioner controller 3, so that battery is in running order with evaporator.Meanwhile, the temperature of cell in the power battery pack that between 1 of entire car controller and battery manager 2, CAN communication obtains, the temperature of evaporator for battery, by CAN communication, pass to air-conditioner controller 3 with the battery cryogenic temperature of setting by calculating, air-conditioner controller 3 calculates the rotating speed (air-conditioner controller 3 also can with reference to conventional control strategy, by calculating the rotating speed of compressor of air conditioner 8) of compressor of air conditioner 8 by these three kinds of factors.
Especially, under above-mentioned refrigeration mode, air-conditioner controller 3 preferentially regulates the rotating speed of compressor of air conditioner 8 according to the temperature of cell in power battery pack: when the temperature of cell in power battery pack reaches default warning value, now the rotating speed of compressor of air conditioner 8 should meet, and the refrigerant gas amount that compressor of air conditioner 8 is exported can meet the refrigeration demand of power battery pack.And when the temperature of cell in power battery pack is in allowed limits time, now the rotating speed of compressor of air conditioner 8 should meet, the refrigerant gas amount that compressor of air conditioner 8 is exported can meet the refrigeration demand in automobile passenger storehouse.
When car load is under charge mode or discharge mode, the first Temperature Detector 41 and the second Temperature Detector 42 will detect that the temperature of cell in power battery pack and the temperature of battery evaporator offer battery manager 2 in real time respectively, entire car controller 1 by and battery manager 2 between CAN communication obtain the temperature of cell in power battery pack, when the temperature of at least two cells is during simultaneously for example, lower than Second Threshold (0 ℃), entering heat management pattern heats to battery power battery pack: entire car controller 1 by and battery manager 2 between CAN communication, first entire car controller 1 sends instructions and allows battery blower fan 9 work to battery manager 2, then for example, entire car controller 1 is given the battery manager 2 adhesive PTC relay that sends instructions after the second time period (30s), thereby ptc heater 5 is worked, to power battery pack, heat.When the temperature of at least two cells is during simultaneously for example, higher than the 3rd threshold value (10 ℃), exit heat management pattern, now entire car controller 1 by and battery manager 2 between CAN communication, send instructions to battery manager 2 and disconnect PTC relay, thereby stop the work of ptc heater 5, then for example, after the 3rd time period (60s), entire car controller 1 sends instructions and allows battery blower fan 9 quit work to battery manager 2.
