0x8023Battery cluster thermal runaway alarm.Critical— level 3
Thermal runaway detected by any of: 1) Vmin<0.5V & Tmax>65°C; 2) Vmin<0.5V & Tmax-Tmin>30°C; 3) Vmin<0.5V & dT/dt>1°C/s; 4) Voltage sampling disconnection fault & Tmax>65°C; 5) Voltage sampling disconnection fault & Tmax-Tmin>30°C; 6) Voltage sampling disconnection fault & dT/dt>1°C/s; Vmin<0.5V & NTC sampling break or short circuit; Aerosol operation (AI1>9V on any BMU as judged by SBCU) & Tmax>65°C; Any BMU air pressure change rate ≥ 0.1 kPa/s.
Send faults externally, limit power, request lower high voltage; if command not received within 5s, cut off the main circuit relay. Latch - manual troubleshooting is required.
