24KW Battery PTC Coolant Heater

PTC is the abbrevjazzjoni of Positive Temperature Coefficient, li means positive temperature coefficient, and generally refers to semiconductor materials or components with a large positive temperature coefficient. The PTC we reference to refers to refers to the positive temperature coefficient thermistor, or PTC thermistor for short. The PTC thermistor for short. The PTC thermistor is a tipiku sensittiv għat-temperatura semikondutturi reżistor.

The battery pack heating system of new energy pure electric vehicles mainly adopts the following two methods: preheating and fuel water heating. By installing a water heating heater on the new energy electric vehicle, the battery pack is heated by heat transfer to reach the normal operating temperature. New energy high-voltage electric heaters can transfer heat to the electric vehicle battery pack to preheat it and keep it at normal operating temperature by installing PTC heaters on new energy electric vehicles.

New energy pure electric vehicle battery pack heating system solution In winter, the range of new energy electric vehicles will generally be greatly reduced, mainly because at low temperatures, the viscosity of the electrolyte in the battery pack increases and the charge and discharge performance of the battery pack decreases. Theoretically: It is forbidden to charge lithium batteries in an environment of minus 20 degrees Celsius (it will cause damage to the battery). Electric vehicles can solve the problem of reduced battery life of new energy electric vehicles in low-temperature environments in winter by installing a parking heater to preheat the new energy vehicle battery pack and bring it to normal operating temperature, and avoid damage to the battery pack caused by low-temperature charging. 

Nota: Jekk hemm mhu le refriġerant fluss in il heater, the heater will enter the high temperature protection state. When the coolant is not drained properly, it will affect the heating capacity of the heater and the accuracy of water outlet temperature collection. Long-termy operation will reduce the liability of the heater.
