Title:
POLYMERIC POSITIVE TEMPERATURE COEFFICIENT DEVICE FOR BATTERY CELL PROTECTION
Document Type and Number:
WIPO Patent Application WO/2018/120007
Kind Code:
A1
Abstract:
Provided herein are approaches for battery cell protection. In one approach, a positive temperature coefficient (PTC) device may include a protection component including a first side and a second side, and a component housing encasing the protection component. The PTC device may further include a first terminal electrically connected through a first opening of the component housing to the first side of the protection component, and a second terminal electrically connected through a second opening of the component housing to the second side of the protection component. In some approaches, the PTC device includes at least one protection strap extending between the first and second terminals to provide enhanced mechanical coupling therebetween, particularly in the event of a fault.
