Electric Car Battery Cooling System

This demo shows an electric vehicle ev battery cooling system.

Electric car battery cooling system.

Today s car news video explains how electric cars work battery and motor technology included could water be the secret. The heating cooling unit consists of three branches to switch operating modes to cool and heat the battery. There are a few options to cool an electric car battery with phase change material fins air or a liquid coolant. Cooling by flooding the battery with a dielectric oil which is then pumped out to a heat exchanger system.

The developed battery thermal management system is a combination of thermoelectric cooling forced air cooling and liquid cooling. Cooling by the circulation of water based coolant through cooling passages within the battery structure. Phase change material absorbs heat energy by changing state from solid to liquid. One to drive the air conditioning compressor and another one to drive the vehicle.

The heat absorbed by the cooling liquid is transported to the heating cooling unit. The liquid coolant has indirect contact with the battery and acts. Forced air assisted heat removal is performed from the condenser side of the thermoelectric liquid casing. The liquid coolant has indirect contact with the battery and acts as the medium to remove the heat generated from the battery during operation.

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. The low voltage battery supplies the electric motor driving the coolant centrifugal pump the radiator fan the evaporator blower and other auxiliary consumers. While changing phase the material can absorb large amounts of heat with little change in temperature. A high voltage battery is connected to two electric motors.
