For traditional electric car, the operating temperature of the battery pack of electric car needs to maintain certain range
It is interior, such as lithium battery is generally 10 DEG C -50 DEG C.This is because the too high service life that can reduce battery of temperature, or even occur quick-fried
The safety problems such as fried.Temperature is too low, can reduce the working performance of battery, and low temperature is also possible to destroy the electrolyte of battery and lead
Send a telegraph the discarded of pond.
In the related technology, cooling generally by air for the heat management device of stroke-increasing electric automobile at present.Air
Disadvantage of both cooling presence: first, cooling air is usually that coolant liquid is connected with air-inlet grille, is being travelled by vehicle

Or when under the conditions of microthermal climate (temperature is less than 0 DEG C), air cooling is then unable to satisfy the needs that battery cools and heats.
In addition, the battery of common electric automobile probably accounts for the 50%-60% of battery pack at present, frame probably accounts for 15%-
20%, control system probably accounts for 5%-10%, and remainder is coolant liquid, and (the above accounting number is equal by general accounting 20%-30%
Refer to mass fraction).The structure of majority is heat dissipation wing plate in frame.Most of coolant liquid main component of common electric automobile
For water, because the specific heat capacity of water is maximum, and the electric car of high power discharge such for such as tesla, the matter of coolant liquid
Amount number can even account for 40% of battery pack or more.In this way battery capacity is reduced, while being also unfavorable for electric car
Lightweight.In addition, cooling water when temperature is lower, is easy frosting, freezes, this not only will affect the performance of system, also will affect
The safety of driver.
Furthermore for traditional electric car, there is no extra waste heat in winter heating to supply the system of crew module
Heat uses, then electric car must consume the electric energy of battery to meet the comfort requirement of crew module.In very arctic weather
Under the conditions of, electric energy required for the electric energy and power propulsion system for crew module's heating is almost same size, electronic at this time
The load of automobile batteries greatly increases, and greatly reduces to the course continuation mileage of automobile.In the hot summer, electric car crew module
