🔥 Provides heating with much less energy in cold weather.

Summary: To heat the cold cabin and battery faster in winter, to collect the waste heat generated in different parts of the vehicle, to reduce the effect of DC charging on the battery in hot weather and keep the charging speed higher, to create different thermal system modes for different heat needs and climate conditions and to perform adaptive heat management.

🔋The heat pump ensures that the battery can be heated as quickly as possible in cold weather, and that the heat generated during hot weather and DC charging can be transferred most effectively, thus extending the battery life and increasing the average charging speed in hot weather.

✅Unlike the PTC heater, the heat pump, which is not a heat generator but a heat transfer system, can collect heat from the air or the vehicle’s battery, engine, and inverter systems and produce 4 kWh of heat by consuming 1 kWh of energy. While the PTC heater system requires more than 1 kW of power at 0 degrees, this falls below 0.5 kW on average in the heat pump system.

🟢Thanks to the use of propane in new-generation heat pumps, system size decreases, weight decreases, and thanks to the 50% higher heat storage capacity of propane, energy consumption also decreases, and the efficiency of the thermal system increases. Chinese companies have developed heat pump systems that reduce energy consumption even at -40 degrees.
