PTC coolant heaters are mainly used in new energy vehicle power battery heating and automotive air conditioning heating. Compared with the traditional automotive thermal management system, the new energy vehicle thermal management system has the following differences: First, the management object extends from the cockpit to the battery, motor electronic control and other fields. The second is that its function extends from simple cooling to heat preservation and heating functions.
Therefore, compared with traditional vehicles, the thermal management system of new energy vehicles has added electronic water pump, electric compressor, electronic expansion valve or four-way valve, cooling plate and heating system
(heat pump or PTC system), etc.
