Learn MoreBattery packs can be cooled using either air cooling, where heat is dissipated into the surrounding air, or liquid cooling, which involves circulating a coolant through the battery pack to facilitate efficient heat transfer. Why is battery cooling important?
Typically, it is integrated with one or more other cooling techniques . Luo et al. achieved the ideal operating temperature of lithium-ion batteries by integrating thermoelectric cooling with water and air cooling systems. A hydraulic-thermal-electric multiphysics model was developed to evaluate the system's thermal performance.
The most efficient technique of a battery cooling system is a liquid cooling loop, particularly designed to dissipate heat from the battery packs into the air. The cooling system's heavyweight affects the EV range as it has to work more to neutralize the payoff load. It also leaves less room for other systems and materials.
EV battery cooling primarily relies on two major techniques: air cooling and liquid cooling. Air cooling is a way to control the battery's temperature using the air around it. There are two types: passive and active. Passive air cooling uses natural air from outside or inside the car to cool or warm the battery.
The battery is cooled by one or more cooling plates through which the coolant flows. The coolant heats up and transfers the heat to another fluid in a heat exchanger. At low ambient temperatures and low cooling capacity, the heat can be transferred to the ambient air via an ambient heat exchanger in the front end of the vehicle.
Battery cooling is part of the vehicle's Battery Thermal Management System (BTMS). The BTMS includes the cooling and heating module, as well as the operating strategy, control system and thermal management software.
