How does the battery heating function work during the set heating period?

During the heating period:

 

• If the cell temperature is between -30℃ and 0℃, the battery will be heated until it reaches 10℃ (heating stops then). If the cell temperature drops below 0℃ again, heating restarts.
• The system prioritizes using PV energy for heating. If PV power is insufficient:
  • It draws energy from the battery if the actual SOC (State of Charge) is above 35%.

  • It draws energy from the grid if the actual SOC is below 35%.
