AI Technical Summary
Existing battery systems face challenges in accurately detecting overheating without erroneous detection, particularly when using single-type temperature measurement elements that may fail to precisely identify abnormal temperatures or overheating conditions.
A battery pack system utilizing a combination of first and second type temperature measurement elements with different resistance characteristics, including positive temperature coefficient (PTC) and negative temperature coefficient (NTC) devices, to enhance temperature measurement accuracy and prevent erroneous detection of overheating.
The dual-element system allows for precise detection of overheating by leveraging nonlinear and linear resistance changes, ensuring accurate temperature measurement and preventing false alarms, thereby enhancing safety and reliability of battery packs.
