Alarms & troubleshooting

BATT_THERMAL_RUNAWAY (Battery Enclosure Bulging & Thermal Runaway Risk)
Power cabinet controller red alarm, temperature sensor triggers high temperature (>50°C) with acid smell
Float voltage temperature compensation unconfigured (-3mV/°C/cell); high ambient heat causes uncontrolled current surge
1. Immediately lower float voltage setting from -53.5V to -51.0V on DC power system and terminate boost charging; 2. Wear safety gloves, trip battery disconnect breaker to isolate bank, and ventilate enclosure; 3. Inspect plastic case for bulging once cooled down; deformed blocks must be permanently decommissioned and replaced.
BATT_INTER_RES_HIGH (Excessive Internal Resistance on Battery Unit)
Monitoring system triggers premature low-voltage drop alert on this specific unit during load discharge
Internal plate grid corrosion, terminal strap micro-fracture, or loose terminal busbar bolt (>6.5 mOhm)
1. Torque all front terminal copper inter-connectors to manufacturer spec (M6 bolt: 11 N*m); 2. Measure internal conductance with calibrated micro-ohmmeter, comparing with baseline (<=4.5 mOhm); 3. If resistance remains >40% above baseline, isolate and replace degraded block with spare unit.
BATT_FLOAT_VOLT_UNBALANCE (Float Charge Voltage Imbalance Across String)
Yellow OBSERVATION LED lit on controller; Battery Monitoring System logs cell voltage delta alarm
Self-discharge variance accumulation across 4S 48V bank, causing some blocks to overcharge (>13.8V) and others to undercharge (<13.2V)
1. Measure open-circuit and float voltage on all 4 blocks, record delta between highest and lowest (norm <= 0.15V); 2. Initiate manual boost equalizing charge cycle (2.35V/cell = 14.1V/block) for 10-12 hours to balance plates; 3. If delta remains >0.3V after equalization, install active Battery Balancer or reorder blocks in series string.
