As shown in fig. 6, the working system of the present invention has the following working principle:

the heat management system provides circulating power for the refrigerant circuit by compressing the refrigerant through the compressor, and provides circulating power for the anti-freezing solution circuit through the water pump. High-temperature high-pressure gas discharged by the compressor is converted into high-pressure low-temperature liquid by radiating heat outwards through the condenser, high-pressure low-temperature liquid refrigerant is throttled and depressurized through the thermal expansion valve, then enters the condenser to be evaporated and exchanges heat with high-temperature cooling liquid in a battery pack loop, and therefore the cooling of the battery pack is achieved. The heating of the battery pack in winter is completed by the water heating PTC connected in series on an external water path, the battery supplies power, the internal controller of the unit adjusts the heating power, and the maximum heating value can reach 30KW.

The dynamic working process is as follows:

a refrigeration mode: the compressor is started, the water pump in the water path is started, and the PTC heater is not started. The high-temperature and high-pressure refrigerant is discharged from the compressor, enters the condenser for condensation, releases heat and cools, is throttled and depressurized through the thermal expansion valve, then enters the beller for evaporation and exchanges heat with the antifreeze, and flows back to the air suction port of the compressor after absorbing heat and evaporating in the plate evaporator to complete a refrigeration cycle. The antifreeze enters a power battery radiator after being cooled in the plate-type evaporator, cools the battery, and brings heat out, so that the purpose of cooling the battery is achieved. The working frequency of the compressor is adjusted by taking the temperature change rate as a judgment condition, so that the refrigerating capacity and the heat productivity of the battery form dynamic balance, the temperature of the cooling liquid is maintained at 15 +/-1 ℃, the battery is ensured to stably run at the temperature with the optimal performance all the time, and the service life of the battery is ensured.

Heating mode: the compressor is in a closed state, the water pump and the PTC heater are started, the cooling liquid enters the power battery radiator after being heated by the PTC heater, the battery is heated, and the heating power of the PTC is adjusted by the controller. This mode is suitable for the case that when the battery temperature is too low, the battery needs to be heated.

Self-circulation mode: the compressor, the fan and the PTC heater are in a closed state, the water pump is started, so that cooling liquid circularly flows in the power battery radiator and the unit, heat in the battery pack is taken out, and the mode is suitable for the condition that the load is small when the battery is charged and discharged, such as spring and autumn.

Failure mode: all parts of the system are in a closed state, at the moment, the battery stops working, a power battery thermal management unit is not needed, and the system can work in a proper temperature range.

Certainly, the utility model discloses also can be a heavy mechanical wall-hanging battery thermal management system, can be used for new forms of energy heavy truck or other forms large-scale machines.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
