  • Load side method of blocking charger voltage from a battery load
    Patent number: 10103556
    Abstract: Methods and apparatus for a protection circuit for a battery and a battery connected device during charging are provided. In one embodiment, the apparatus includes a load-blocking switch connected between a rechargeable battery and an electronic device and a charge-blocking switch connected between the rechargeable battery and a charger. The apparatus also includes a safety circuit to detect a voltage across and the current flowing through the rechargeable battery. The safety circuit opens the load-blocking switch and the charge-blocking switch when it detects that the voltage across or the current flowing through the battery exceeds a predetermined threshold.
