Cooling system in an electric car: What is it and how does it work?

In any working system where the temperature is likely to rise, COOLING became a critical factor. We often associate the need for cooling with combustion engines, but electric vehicles also need efficient cooling systems to control the temperature of their components.

she cooling system of an electric car It plays a fundamental role in keeping the temperature of the battery and the electric motor under control. Unlike traditional gasoline-powered vehicles that rely on liquid cooling systems to prevent engine overheating, electric cars require more complex systems that can handle the unique demands of their powertrain.

Typically, an electric car cooling system consists of several key components, including a radiator, pump, and heat exchanger. The radiator is responsible for dissipating the heat generated by the battery and engine, while the pump circulates the coolant in the system to control the temperature. A heat exchanger, usually located in the air conditioning unit, helps remove excess heat from the refrigerant before it is recirculated through the system.

One of the most important challenges when designing a cooling system for an electric vehicle is managing the heat produced by battery and motor. These vehicles generate a lot of heat during operation, which can lead to faster battery degradation if not properly controlled.

To address this issue, many electric vehicles use liquid-cooled batteries, which are designed to dissipate heat more efficiently than air-cooled batteries.

Another important challenge is to ensure that the cooling system is efficient enough to meet the powertrain needs. Electric vehicles require a lot of energy to accelerate quickly and maintain high speeds, which can put a strain on the cooling system.

Cooling of electric vehicles: air or liquid cooling

There are two main methods of cooling electric vehicles: air cooling and liquid cooling. the air cooling takes advantage of the flow of fresh air from the environment to cool the battery pack, while the liquid cooling It uses a cooling fluid similar to the cooling system of an internal combustion vehicle to cool the battery, with the help of an electric pump and radiator.

It is important to note that the optimal operating range of a lithium-ion battery is between 59°F and 104°F, and exceeding these temperature limits can lead to deterioration. Therefore, the choice between air or liquid cooling systems is important to maintain the performance and life of the batteries in electric vehicles.
