Abstract
The present invention relates to a fire suppression arrangement (8) for suppressing a fire in a battery pack, such as a lithium-ion battery pack (7), said arrangement (8) comprising said battery pack (7), and a thermal management system (5) comprising a liquid circuit (13) for circulating a liquid to control the temperature of said battery pack (7). The liquid circuit (13) comprises at least one opening (25) which is closed by a sealing member (35) comprising a fusible portion (43), wherein said fusible portion (43) is configured to melt when exposed to a temperature above a predetermined activation temperature, thereby allowing liquid to be discharged from said liquid circuit (13) through said opening (25) to cool a portion of said battery pack (7) in the event of an abnormal temperature rise near said opening (25).
Claims12
A thermal management and fire suppression system, comprising:
- a battery pack;
- and
- a liquid circuit for circulating a liquid to control a temperature of the battery pack;
- wherein said liquid circuit comprises at least one opening that is sealed by a mist spraying nozzle, the mist spraying nozzle having a discharge opening, wherein the discharge opening of the mist spraying nozzle is sealed by a fusible portion that covers the discharge opening;
- and
- wherein the fusible portion is configured to melt when exposed to a temperature above a predetermined activation temperature, thereby allowing the circulating liquid to be discharged from said liquid circuit through the discharge opening of the mist spraying nozzle to cool a portion of said battery pack.
