Why thermal management so important in electric vehicles
Why is thermal management so important in electric vehicles? In order to be able to operate electric vehicles with particularly high efficiency, the optimal temperature range of motors, power electronic equipment and batteries must be maintained. This requires a complex thermal management system.
The thermal management system of traditional vehicles is mainly divided into two parts, one is the thermal management of the engine, and the other is the thermal management of the interior. For new energy vehicles, especially electric vehicles, the thermal management system has three main parts:
The first part is the thermal management of motor and electronic control, mainly the function of cooling;
The second part is battery thermal management; The third part is air conditioning thermal management.
The three core components of motor, electric control and battery have very high requirements for temperature control.
Compared with fuel vehicles, electric drive has many advantages. For example, it can provide maximum torque from zero speed and can operate up to three times the nominal torque in a short time. This enables very high acceleration and makes the transmission obsolete. In addition, the motor recovers the driving energy during braking, which further improves the overall efficiency. In addition, they have a small number of vulnerable parts, so the maintenance cost is low.
Compared with fuel vehicles, electric motors have one disadvantage. The temperature control of battery module is more complex and requires higher requirements. If it is not well controlled, it is very easy to lead to vehicle spontaneous combustion, which requires effective thermal management of electric vehicles.
With the advent of the era of electrification, in addition to the automotive industry, other industries, such as mobile phones, computers, servers, medical equipment, etc., are facing the problem of heat dissipation that can not be ignored.
Therefore , thermal solution design is very important in every industry. Sinda Thermal can provide varieties heatsinks and coolers which inlcuding aluminum extruded heatsink, high performance heatsink, copper heatsink, skived fin heatsink, and heat pipe heatsink widely used in many application fields. please contact us if you have any questions about thermal solution.
