Resettable over current protection circuitry

Abstract

A resettable over current protection circuitry for an energy storage system of a vehicle is presented. The resettable over current protection circuitry is configured to be arranged between one or more battery cells and a load and comprises a transistor device configured for controlling an electrical connection between the battery cell and the load. The resettable over current protection circuitry further comprises current sensor circuitry for measuring a load current between the one or more battery cells and the load and control circuitry configured to control the transistor device to break the electrical connection between the one or more battery cells and the load responsive to the load current being above a first predetermined threshold during a first predetermined time.

Dependencies are inferred from the claim text.
