| titleOfInvention | Automotive battery active safety valve and lithium battery based on shape memory alloy ring |
| abstract | The present invention provides an active safety valve device in the field of lithium battery safety. Technical Field An active safety valve for an automobile battery based on a shape memory alloy ring and a lithium battery include a battery shell, a valve cover of the safety valve and a shape memory alloy ring. The valve cover is fixed on the battery case, one end of the shape memory alloy ring is fixed on the battery case, and the other end of the shape memory alloy ring is fixed on the safety valve cover; the safety valve cover includes an upper end and a The lower end, the upper end and the lower end are connected and arranged, a weak groove is opened at the connection between the upper end and the lower end, the shape memory alloy ring has a shape memory effect through temperature changes, and the upper end and the lower end are transformed by the length of the shape memory alloy ring And tear to form vents. The present invention responds more directly and quickly, can release internal gas and heat in advance, and effectively reduces the risk of thermal runaway. Part of the components of the device can be reused to improve service life and reduce maintenance costs. |
