Alarms & troubleshooting

BATT_TERMINAL_OVERTEMP (Front Terminal Post Overheating & Melt Hazard)
BMS thermal lug probe triggers overtemp alarm (>70°C); thermal camera shows bright white-hot busbar hotspot
Under 170Ah heavy current, terminal bolt loosened due to thermal cycling/vibration, creating focal contact resistance heating
1. Immediately throttle rectifier current output and allow terminal connections to cool down; 2. Unbolt busbars, polish blackened terminal pads with fine emery cloth, and apply thin film of antioxidant electrical grease; 3. Install new stainless bolts torqued to precise 11 N*m; verify contact resistance is restored to <50 micro-ohms.
BATT_CASE_LEAKAGE (Pressure Safety Vent Valve Acid Seepage/Rupture)
Battery tray fluid presence sensor trips; white crystalline sulfate deposits visible around rubber vent plug
Hardened one-way EPDM pressure vent cap failing to reseal under overcharge pressure, releasing acid mist
1. Wear acid-resistant gloves, neutralize crystalline deposits with 5% sodium bicarbonate solution and wipe dry; 2. Check if one-way vent valve reseals firmly and ensure battery rack exhaust ventilation is unhindered; 3. If plastic case is cracked or leaking continuously, decommission block immediately; never attempt glue repair.
BATT_FLOAT_RIPPLE_HIGH (Excessive AC Ripple Voltage on Float Line)
AC ripple monitor alerts ripple component exceeds 200mV RMS limit; battery experiences micro-heating
Aged DC output filter capacitors in rectifiers injecting high-frequency ripple into battery string, eroding plate grids
1. Measure AC ripple across battery terminals with oscilloscope or True-RMS meter (Vpp must be <500mV); 2. Switch off rectifiers sequentially to pinpoint the module with degraded output filter stage; 3. Replace faulty rectifier to eliminate parasitic AC harmonics degrading the 170Ah chemical system.
