In addition, the chemical reaction and the ohmic resistance of electric automobile battery can be continuous in the operation in-process generate heat, the power of group battery to a great extent depends on the temperature of battery, the normal performance of group battery will be influenced to the high temperature, moreover, under some adverse circumstances operating mode, electric automobile need be continuous output high power, and power battery will arouse the sharp rising of the inside temperature of group battery under the continuous output of long-time high power, if the heat dissipation untimely also can cause the thermal runaway of power battery or even can cause electric automobile's the accident of catching a fire. Therefore, an efficient cooling system is of great importance for protecting the safety of the battery. Common types of heat dissipation systems of electric automobiles include air cooling, liquid cooling, phase change materials and the like, and the air cooling is limited by air flow rate and has poor heat dissipation effect; although the phase-change material has an excellent heat dissipation effect, the phase-change material has poor heat dissipation efficiency and is difficult to quickly respond when the local temperature sharply increases, the uniformity of the internal temperature of the battery pack is slightly poor, various comprehensive factors are considered, the conventional electric automobile mainly adopts a liquid cooling mode, but liquid has serious potential safety hazards, and if the cooling liquid leaks, the battery is extremely easy to short and catch fire.
