Electric Car Battery Cooling System

Cooling by flooding the battery with a dielectric oil which is then pumped out to a heat exchanger system.

Electric car battery cooling system.

One to drive the air conditioning compressor and another one to drive the vehicle. Today s car news video explains how electric cars work battery and motor technology included could water be the secret. Cooling by the circulation of water based coolant through cooling passages within the battery structure. The developed battery thermal management system is a combination of thermoelectric cooling forced air cooling and liquid cooling.

There are a few options to cool an electric car battery with phase change material fins air or a liquid coolant. This demo shows an electric vehicle ev battery cooling system. A high voltage battery is connected to two electric motors. Forced air assisted heat removal is performed from the condenser side of the thermoelectric liquid casing.

The heat absorbed by the cooling liquid is transported to the heating cooling unit. The low voltage battery supplies the electric motor driving the coolant centrifugal pump the radiator fan the evaporator blower and other auxiliary consumers. The heating cooling unit consists of three branches to switch operating modes to cool and heat the battery. The developed battery thermal management system is a combination of thermoelectric cooling forced air cooling and liquid cooling.

Electric cars in europe ca engine ban ev100 pledge new battery cooling. The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. Detailed experiments are carried out on a simulated electric vehicle battery system. While changing phase the material can absorb large amounts of heat with little change in temperature.
