Abstract
A fire suppressing apparatus for a battery unit is provided, the apparatus comprising an aerosol generator (2) and a sensor (3) arranged to detect measurable characteristics and/or effects resulting from battery thermal runaway and to trigger the aerosol generator (2) when said characteristics and/or effects are detected.
Claims (14)
1. A system comprising a fire suppressing apparatus (1) and a battery unit com- prising at least one battery cell (10), the system comprising:
2. - an aerosol generator (2)
3. - a sensor (3) comprising a membrane (4),
4. š.~\\\. 0 “\ \R,.\ *MMA \ fi ul ~ \ “M mm: czïwvšàšš: EQ :Sa *mmm
5. fire suppressing apparatus (1) is mounted to the battery unit (5) such that the aerosol generator (2) and the battery unit (5) share a common continuous volume (8),
6. wherein the membrane (4) is configured to deform in response to a pressure increase in the common continuous volume (8) due to thermal runway of one of the at least one battery cell (10), and
7. wherein the deformation of the membrane is configured to apply a force on a power transmission unit (15) connected to a trigger mechanism (18) of the aerosol generator (2) to trigger the aerosol generator (2).
8. The system according to any one of claims 1, wherein the pressure sensor (3) is configured to trigger the aerosol generator (2) at a detected differential pressure of approximately 0.2 - 0.8 bar, more preferred 0.4 - 0.6 bar and most preferred 0.5 bar compared to a reference pressure.
9. The system according to any one of the preceding claims, wherein the bat- tery unit (5) comprises a housing (9), and wherein the fire suppressing appa- ratus (1) is mountable to an outer surface of the housing (9) or enclosed within the housing (9) of the battery unit (5).
10. The system according to any one of the preceding claims, wherein the aero- sol generator (2) comprises a solid compound, wherein the solid compound preferably is potassium nitrate.
11. The system according to any one of the preceding claims, further comprising a pressure relief valve (6) configured to open and release gas from the com-
12. mon continuous volume (8) to an ambient (7) when pressure in the common
13. continuous volume (8) exceeds a predetermined differential pressure thresh- old value.
14. 14 Amendment copyThe system according to claim 5, wherein the pressure relief valve (6) is con- figured to open at a differential pressure compared to ambient being 0.1-0.5 bar above a threshold value for triggering the aerosol generator (2).The system according to claims 5-6, wherein when the pressure relief valve (6) is open, the pressure relief valve (6) is configured to close when pressure in the common continuous volume (8) falls below a predetermined threshold value, which pressure difference preferably is approximately 0.2 - 0.8 bar, more preferred 0.4 - 0.6 bar and most preferred 0.5 bar compared to the ambient (7).The system according to claims 5-7, wherein the pressure relief valve (6) comprises a non-flammable material.A method for suppressing a fire in a system according to any one of the pre- ceding claims, the method comprising the steps of- deforming, by means of a pressure increase due to battery thermal runa- way, the membrane- applying, by means of the deformed membrane a force on the power transmission unit (15) connected to the trigger mechanism (18) of the aerosol generator (2),- triggering, by means of the trigger mechanism (18), the aerosol genera- tor (2).The method for suppressing a fire according to claim 9, further comprising a step of opening a pressure relief valve (6) when a pressure difference be- tween the common continuous volume (8) and the ambient volume (7) ex- ceeds a predetermined threshold value, and a step of at least partially closing the opened pressure relief valve (6) when the pressure difference between the common continuous volume and the ambient volume (7) is reduced, preferably when the pressure difference is 0.2 - 0.8 bar, more preferred 0.4 - 0.6 bar and most preferred 0.5 bar.
