Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and detailed description of the invention this utility model is described in further detail.
As shown in fig. 1, this utility model provides a kind of electric powered motor battery pack heat management system, and it mainly wraps
Including liquid-way system, liquid-way system includes the cold battery case of liquid for holding liquid (i.e. liquid working substance) and battery, the cold battery case of liquid
The mode using liquid circulation is battery heating and heat radiation.Specifically, liquid is sent into heating by pipeline by the cold battery case of liquid
Device, the liquid working substance through heater enters into three-way solenoid valve by pipeline, and liquid working substance is divided into two-way by three-way solenoid valve
Being respectively fed to heat radiator assembly and water pump, the liquid after heat radiation is sent into water by its internal radiator fan by heat radiator assembly
Pump, the liquid in the three-way solenoid valve of reception and heat radiator assembly will be pumped into the cold battery case of liquid by fluid path by water pump.
Above-mentioned liquid-way system also includes the expansion tank for shunting the liquid in heat radiator assembly.If through heating
The temperature of the liquid working substance of device heating is higher, then liquid working substance volume can expand change greatly, and now, partially liq can be by pipe
Road is flowed into expansion tank and shunts, after fall volume recovers at temperature, again in pipeline inflow radiator assembly, and then
Enter in water pump, be pumped in the cold battery case of liquid.
This utility model also includes the control system that the operation of opposite heat tube reason system is controlled, and this control system includes control
Device processed and the temperature sensor being arranged in the cold battery case of liquid, controller battery case cold with liquid, heater, water pump, radiator are total
Become, three-way solenoid valve electrically connects.By controller to the opening and closing of heater, the commutation of three-way solenoid valve, the wind of heat radiator assembly
The opening and closing of fan is controlled.This controller can be the BMS control system being connected with car load.
The temperature of the battery core in the cold battery case of liquid is measured in temperature sensor in real time, and temperature signal is passed to BMS,
BMS presets the various temperature thresholds of needs, BMS according to the temperature threshold set and the temperature signal of reception to each device
Automatically control.This utility model is as follows to the concrete control process of battery pack heat management device by BMS:
(1) when battery core temperature is less than m DEG C (preferably 0 °), battery core temperature is too low, and now BMS controls heater, water pump
Work, the liquid working substance after heater via heating flows through three-way solenoid valve, water pump, enters the heat exchange unit device in the cold battery case of liquid
Part, heats to battery；
