In order to solve the embarrassment of turning on the heating and air conditioning in winter, Tesla is equipped with an electric heat pump system for model 3 / y. compared with direct resistance heating, the heating efficiency of the heat pump is more efficient.

It is understood that the heat pump can not generate heat, but through the system to deliver hot air to a specific area. The compressor uses electricity to deliver the refrigerant to all parts of the system, capture heat from the outside, and then deliver the heat to the interior of the vehicle.

Moreover, this kind of heat pump can generate 3KW of heat energy with only 1kW of electric energy, and the heating efficiency is very high. Compared with direct heating PTC resistor, heat pump heating effect is better, and it will not consume too much vehicle battery power.

Tesla Model y heat pump

However, the heat pump air conditioner that Tesla has just loaded into the car is just about to show off its muscles in winter, when it has trouble.

Recently, some media reported that Tesla Model y and model 3 are prone to heat pump failure in cold climate. It is reported that the fault may be caused by a loophole in the vehicle software configuration.

It is reported that the Tesla models with this problem only involve model y and model 3 models equipped with new heat pump system.

After the introduction and replacement of the heat pump system in these two models, the problem that the heat pump system can not work normally often occurs in severe cold climate.

According to the feedback of some car owners, the heat pump problem can be solved through Tesla remote diagnosis and software update. So foreign media speculated that Tesla software may be equipped with loopholes.

Tesla has not yet made an explanation, and we will keep an eye on it.
