Electric Car Battery Cooling System

This demo shows an electric vehicle ev battery cooling system.

Electric car battery cooling system.

While changing phase the material can absorb large amounts of heat with little change in temperature. The heating cooling unit consists of three branches to switch operating modes to cool and heat the battery. A high voltage battery is connected to two electric motors. 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 developed battery thermal management system is a combination of thermoelectric cooling forced air cooling and liquid cooling. The liquid coolant has indirect contact with the battery and acts as the medium to remove the heat generated from the battery during operation. Electric cars in europe ca engine ban ev100 pledge new battery cooling. Phase change material absorbs heat energy by changing state from solid to liquid.

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. Detailed experiments are carried out on a simulated electric vehicle battery system. 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 heat absorbed by the cooling liquid is transported to the heating cooling unit. 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.
