Electric vehicle coolant usage

As we all know, fuel vehicles are driven by fuel engines, while electric vehicles are driven by battery packs and electric motors, so the latter do not need to replace the oil filter and are easier to maintain. The coolant in fuel vehicles is to help the engine dissipate heat and maintain normal working temperature, but it must be controlled between 87℃ and 105℃. In electric vehicles, the coolant is used to cool the core components such as motors, batteries, and battery management systems.
When the battery is charged and discharged, a lot of heat is generated, which requires timely temperature control, otherwise it will affect the consistency of the battery and greatly shorten the battery life. Therefore, the coolant not only provides cooling protection when the vehicle is driving, but also protects the safety of the vehicle when it is parked and charged.
The battery has very precise requirements for temperature control, and the temperature difference is required to be around 5℃. Because of the special structure of the battery, the cooling water channel structure is forced to be more complex and narrow than that of fuel vehicles, so the quality of the coolant is required to be higher.
The harm of ignoring the maintenance of the cooling system
During the driving and charging process of electric vehicles, if the coolant is insufficient, the battery cannot be cooled in time, which will cause considerable damage to the battery and may even cause an explosion. The increase in motor temperature causes the motor to short-circuit or even burn out;

If the antifreeze is not replaced for a long time, it will not only deteriorate, but also cause scale corrosion, damage the radiator and pipes, and once it leaks, it will cause a battery short circuit and fire, which will endanger personnel safety.
Therefore, it is essential to replace high-quality antifreeze coolant in time. It can not only solve the above hazards, but also reduce worries.
Warm reminder: Under normal circumstances, it is recommended to replace the antifreeze coolant after 2 years or 40,000 kilometers of driving.
