Warm up function is exclusively available in warm-up versions. All batteries must be warm-up versions; otherwise the Warming up function will not operate. Heating control is based on internal cell temperature rather than ambient temperature. Battery can only discharge when internal temperature is above -10°C and only charge above 0°C. These internal-cell limits are separate from root-reviewed warm-up model-table operating ambient ranges. Self-heating state: SOC >= 10%, MinCell Temperature < Start Temperature, not in low-temperature protection, within set heating time. Resistor is powered by battery; inverter power control not affected. Inverter-controlled heating: SOC < 10% or in low-temperature protection, and MinCell Temperature < StartTemperature within set heating time. Resistor powered by inverter; inverter can only provide heating power and cannot respond to other charging/discharging requests. Page 11 app controls print heating start temperature 1~9℃ optional, stop 10~15℃ optional, and three time periods. Values are control settings, not battery charge/discharge operating limits.
