An event is added to the log whenever the BMS detects a fault. Up to 24 events may be recorded, after which the oldest event is overwritten with the new event.

To scan the log, press the '<' or '>' or Enter keys.

For the selected event, this screen displays the following:

• The event number
• The cause of this event:
  • Driving off while plugged in
  • Interlock is tripped
  • Communication fault with a bank or cell
  • Charge overcurrent
  • Discharge overcurrent
  • Over-temperature fault
  • Under voltage
  • Over voltage
  • No battery voltage
  • High voltage B- leak to chassis
  • High voltage B+ leak to chassis
  • Contactor K1 shorted
  • Contactor K2 is shorted
  • Contactor K3 shorted
  • No precharge
  • Open K2
  • Excessive precharge time
  • EEPROM stack overflow

• The number of the power-up cycle (how may times the BMS was powered up, since its manufacture)
• The power up time in this power cycle, in seconds, when the fault occurred

• Source current at the time, in A, including direction
• Load current at the time, in A, including direction
• Whether the BMS was powered through its SOURCE input
• Whether the BMS was powered through its LOAD input
• Whether the interlock input was abnormal at the time
• Whether the Contactor Request input line was active at the time
• Whether there was a Contactor Request on the CAN bus at the time

• Whether the HLIM (High Limit) logic output was active at the time
• Whether the LLIM (Low Limit) logic output was active at the time
• Whether the FAN output was driven on at the time
• The CCL (Charge Current Limit) level at the time, from 0% (no charging allowed) to 100 % (full charging allowed)
• The DCL (Discharge Current Limit) level at the time, from 0% (no discharging allowed) to 100 % (full discharging allowed)
• The state of the relay (contactor) drive at the time

• The pack's SOC (State Of Charge) at the time, 0% (Empty) to 100 % (full)
• The pack's voltage at the time, in Volts
• The number of banks that were not reporting at the time, and the number of one of the missing banks
• The number of cells that were not reporting at the time, and the number of one of the missing cells

• The range of cell voltages at the time, and the number of the most discharged and most charged cells, in Volts
• The range of cell-board temperatures at the time, and the number of the coldest and hottest cell-boards, in Degrees Celsius
• The numbers of loads that were on at the time
