Abstract:
Provided is a lithium ion secondary battery system having excellent reliability.
Provided is a lithium ion secondary battery system including, at least a lithium ion secondary battery including a positive electrode and a negative electrode, and a lithium deposition sensor. In this lithium ion secondary battery system, the lithium deposition sensor includes an endotherm detector, and the endotherm detector detects endotherm in a constant current charging range.
