Electric Car Battery Cooling System

One to drive the air conditioning compressor and another one to drive the vehicle.

Electric car battery cooling system.

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. Cooling by flooding the battery with a dielectric oil which is then pumped out to a heat exchanger system. Today s car news video explains how electric cars work battery and motor technology included could water be the secret. The liquid coolant has indirect contact with the battery and acts.

A high voltage battery is connected to two electric motors. Detailed experiments are carried out on a simulated electric vehicle battery system. Electric cars in europe ca engine ban ev100 pledge new battery cooling. This demo shows an electric vehicle ev battery cooling system.

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. 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 low voltage battery supplies the electric motor driving the coolant centrifugal pump the radiator fan the evaporator blower and other auxiliary consumers. Phase change material absorbs heat energy by changing state from solid to liquid. The heating cooling unit consists of three branches to switch operating modes to cool and heat the battery. The heat absorbed by the cooling liquid is transported to the heating cooling unit.
