Do pure electric vehicles have a radiator?
2 Answers
Pure electric vehicles have a radiator. Heat dissipation: The cooling water absorbs heat in the water jacket, dissipates the heat when flowing to the radiator, and then returns to the water jacket for circulation, achieving temperature regulation and maintaining the engine's appropriate working temperature. Self-cooling implementation: Water has a relatively large specific heat capacity. Only electric vehicles with particularly high power density require water cooling and thus need a radiator. Cleaning the radiator: After removing the radiator, it can be cleaned. The exterior is easy to clean; simply rinse to remove impurities and dirt. However, internal descaling is more troublesome, but a scale remover can also be used.
I've been driving a pure electric vehicle for several years and noticed that it indeed doesn't have the traditional car's radiator tank, which is used to cool the internal combustion engine. Since EVs don't have an engine, they don't need it. However, they do have a thermal management system that typically uses coolant to regulate the temperature of the battery, motor, and power electronics. This system somewhat resembles the piping in a refrigerator, not an exposed design like a radiator tank. The battery tends to generate heat during high-speed driving or fast charging, and without proper cooling, its performance could degrade or even shorten its lifespan. I recommend owners regularly check the coolant level and system sealing. Although it eliminates the step of refilling the radiator tank, making maintenance simpler, this is where EVs shine—cleaner design, fewer failure points, and no engine-related cooling issues. But don't ignore the cooling system warning light to prevent potential safety risks from battery overheating. Overall, the absence of a radiator tank represents significant progress in EV technology, delivering a quieter and more efficient driving experience.
