Chery New Energy eq has no heater, which is caused by internal switching. It may be caused by the engine cooling system; it may also be caused by poor working of the heater control mechanism. When repairing, first determine which cause is the cause, and then perform corresponding repairs. The method of identification is very simple. Look at the temperature of the two water inlet pipes of the small heater water tank. If both pipes are hot enough, it means there is a problem with the air volume control mechanism. On the other hand, if both water pipes are cold, or one is hot and the other is cold, it indicates a problem with the cooling system.
Causes
On the one hand, the heater control mechanism is not working properly and the car heater is not hot. It is recommended to replace it; on the other hand, there is a problem with the air conditioning heat pump of the electric vehicle. Replacement is recommended. Electric vehicles are realized using PTC or air-conditioning heat pumps. Currently, PTC heating is the main method. The air conditioning compressor of electric vehicles is driven by electricity to run continuously.
New energy vehicles use heating pipes to replace the heater water tanks of gasoline vehicles, and the effect is the same. Heating the car will not lose gasoline, because the gasoline car itself must dissipate heat through the water tank, and the heat cannot be used to do work, so heat energy loss is inevitable. The warm air can only use this heat energy, so the fuel consumption does not increase, but the heating The tube consumes electricity.
