Why LFP
LFP chemistry has a higher thermal runaway onset temperature than NMC and does not release oxygen from the cathode. This is the primary reason why stationary storage systems use LFP exclusively.
Layers of protection
- Battery management system (BMS) monitoring voltage and temperature of every cell
- Combustible gas and carbon monoxide detection at module level
- Zoned suppression system and emergency ventilation
- Partitions and spacing between containers per the approved design
- Remote shutdown and signaling to the facility's central system
Formal approvals
The design requires sign-off by a certified fire protection expert, and before commissioning, notification to and acceptance by the district commander of the State Fire Service (PSP). For large installations we also prepare a fire scenario and instructions for emergency services.
