EVs are taking over ICE vehicles. However, with the advent of EVs, there was a confusion with regards to their systems. Today, with all the other doubts slowly fading out, the problem that persists is the thermal management. 

In conventional automobiles, thermal management is needed for cooling the engine. The coolant, thermostat, and radiator system eliminate heat from the engine. In EVs, thermal management includes the cooling of power electronic systems, batteries and the motor.

Thermal Management in EVs

The EV thermal management is important, because it affects the reliability, performance, and sturdiness of these vehicles. EVs require optimal temperatures for efficient function. 

When upheld at an ideal temperature, the health, battery charge, and capacity are kept intact. 

Thermal Management of the Battery

The life, performance and cost of EVs are directly dependent on thermal management. The obtainability of discharge power for starting and speeding up, charge acceptance throughout regenerative braking, and battery health are best at optimum temperatures. 

With the increase in temperature, the life of the battery, EV driveability, and fuel efficiency reduce. Bearing in mind the thermal effect of the battery on EVs, battery thermal management is considerably important.

Cooling Loop in Electric Vehicles

For high efficiency in EVs, maintaining optimal temperature is the need of the hour. The ideal temperature is controlled by the cooling system of the EV. 

Frequently, the cooling system controls the temperature of the EV, including the temperature of battery and motor. In the cooling loop, a coolant is dispersed with the use of an electric pump for cooling of the batteries, motor, electronics, and related systems. 

In EVs, radiators are put to use in the cooling loop for releasing heat to the ambient air. The AC is used in EVs for cooling down the systems in the cooling loop and evaporators are combined for removing heat from the loop.

Summing Up the Scene

The thermal management in EVs adjusts to temperature conditions and controls ideal temperatures in battery, power electronics drives, and motors.  It is important, as it impacts an EVs safety and driveability.

For these reasons, the demand for the automotive thermal management system will continue to grow in the near future.
