Abstract
The rechargeable battery protection circuit of this invention is provided with a switching system connected in series with the rechargeable battery, a current detection system to measure charging current flowing through the rechargeable battery, and a control system to control the switching system on and off depending on measurement results from the current detection system. The control system puts the switching system in the off state when charging current greater than a specified value flows through the rechargeable battery. This prevents rechargeable battery charging with excessive current.
