KREISEL BATTERY PACK KBP63-A
The KREISEL BATTERY PACK KBP63-A is a high‑power lithium‑ion battery system designed to provide emergency power on board ships, delivering instant start‑up and zero‑emission backup for critical loads.
Inspector Detail
▸
Common issues
- Cell imbalance developing over charge cycles, reducing usable capacity
- Battery Management System (BMS) communication faults with the vessel's power management system
- Cooling/thermal management faults leading to temperature-related derating
- Capacity fade (state of health decline) with cycle count and calendar age
- Connector/busbar corrosion at high-current terminals
- Insulation resistance degradation in the battery compartment
- Ventilation system fouling reducing effectiveness of off-gas extraction
Inspection checklist
- Check the BMS status/alarm log for cell voltage or temperature deviations
- Verify insulation resistance of the battery system per class requirement
- Inspect the battery room/enclosure ventilation and gas detection system
- Check the fire suppression/detection system dedicated to the battery space
- Verify state of health (SOH) and state of charge (SOC) readings against baseline
- Inspect high-current connections/busbars for corrosion or loose torque
- Confirm the emergency disconnect/isolation switch operates correctly
- Check thermal management (cooling) system operation
- Review the charge/discharge cycle log against the maker's operating envelope
Service intervals
| BMS diagnostic/software check | annually, per maker schedule |
| Insulation resistance test | annually, per class requirement |
| Ventilation/gas detection system test | annually, per class/SOLAS battery installation rules |
| High-current connection torque check | annually |
| Full capacity/SOH verification test | every 1-2 years, per maker recommendation |
Critical spares
- BMS communication fuses
- Ventilation fan units
- Gas detection sensor heads
- Main contactor/isolation switch
- Cooling system components (pump/fan) for the battery thermal management circuit, where fitted
Safety
- Thermal runaway risk - a lithium-ion cell fire requires specific extinguishing procedures, not simply water or CO2 in all cases
- High DC voltage/arc flash hazard at battery terminals and busbars
- Off-gas release risk (flammable/toxic) in the event of cell failure - ventilation integrity is safety-critical
- Risk of stranded energy after a fault - isolation procedures must be followed before any intervention
Class survey
Battery-based emergency power installations are surveyed against the applicable class battery notation, covering ventilation, dedicated fire detection/suppression, BMS functionality, isolation arrangements, and verification that the installation matches the approved battery safety documentation on file.
