Description

Technical Field

[0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a new energy vehicle battery pack heater. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] In the northern high-cold areas, the existing technology is to heat the new energy vehicle itself through the battery power of the new energy vehicle itself. The battery can only be used normally after it is preheated to a certain temperature. The technical disadvantage is that when the temperature is too low, the new energy vehicle battery cannot work normally or even cannot be charged due to low temperature protection. For this reason, it is necessary to use a special heater to heat the battery. In the existing technology, new energy vehicles are equipped with hydroelectric heaters, which heat the vehicle's air-conditioning system or the entire vehicle through hydroelectric heating. However, this technology has not been combined with the battery heating technology of new energy vehicles, resulting in the existing technology often using a single electric heating method to increase the temperature of the battery. However, the electricity consumed by this battery preheating causes the new energy vehicle to use electricity at low temperatures, further aggravating the energy consumption. The technical difficulty of combining direct electric heating with a hydroelectric heater is that during the long-term use of the hydroelectric heater, impurities are inevitably mixed in the water body. Once the hydroelectric heater is used to heat the battery, it is necessary to frequently clean the heat exchange structure fitted to the battery, which increases the workload of the car owner.
