BATTERY PROTECTION AND VERIFICATION SYSTEM

A battery protection and verification system (100) for a battery (102) composed of a plurality of battery cells (104) comprises: a plurality of voltage measurement units (106, 106a, 106b), each adapted for receiving a cell voltage (107, U) from one of the battery cells (104), for detecting an overvoltage from the cell voltage (107, U) and for outputting an overvoltage protection signal (108) for switching the battery (102) into a safe state when the overvoltage is detected; a test signal generator (130) adapted for providing an overvoltage test signal (136) to an input of at least one of the voltage measurement units (106, 106a, 106b), the overvoltage test signal (136) simulating the overvoltage; and a test controller (132) adapted for controlling the test signal generator (130) and for verifying whether the overvoltage protection signal (108) is output when the overvoltage test signal (136) is provided to the input of the at least one voltage measurement unit (106, 106a, 106b).
