Patent Pending
- The invention is a cost-efficient device made of a SMA that is shaped to maintain the electrical connection between a lithium-ion battery and a conductive plate. At a manufacturer specified temperature (higher than the operating temperature), the SMA returns to its original remembered shape, therefore breaking the electrical connection.
- The invention prevents electrical overheating to prevent fires and save battery cells, making the battery repairable. It is widely applicable to any electrical device that has the potential to overheat, such as electric vehicles, computers, and battery-operated tools.
- It is estimated that the SMA thermal device would add less than 10% to the cost of the battery.
