There are many types of heating artifacts for new energy vehicles, such as on-board heaters, and the most common one is the equipment that uses electricity as energy to warm up. However, it is recommended not to use it for a long time in the flameout state, otherwise it will damage the battery. Because if the car heater is used in the flameout state, the power consumed is the power of the car battery, and long-term use will lead to the loss of battery power, further damaging the battery.
