SYSTEM AND METHOD FOR FIRE PROTECTION

摘要

The invention relates to a system for fire protection of a battery storage comprising at least one battery module, which battery module in turn comprises one or more battery cells. In accordance with the invention, the battery storage comprises a housing connected to an inlet arrangement for injection of a fire extinguishing means into the housing. By means of the invention fire-extinguishing means is injected into the housing containing the failing battery cell. The injected gas sweeps away gases released from the failing cell and also cools down the one or more battery cell(s), thereby preventing avalanche effects of the failing battery cell heating adjacent battery cells and thereby regressing the arising fire before actually catching fire. By transporting away the highly inflammable gases the risk of fire is greatly reduced. The system thus provides means for preventing fire and for quickly extinguishing a fire that still has occurred.
