Arrangement for measuring energy storage and electric circuit-breaker, has evaluation unit which is connected with circuit breaker which has resistance, where voltage value is determined to circuit breaker with evaluation unit

摘要

The arrangement has an evaluation unit which is connected with a circuit breaker (L-S) which has a predetermined resistance, where a voltage value is determined to the circuit breaker with the evaluation unit. A current value is determined from the voltage value. An electrical energy storage (C-1,C-2) is formed as an electrical cell of a battery module. The circuit breaker is a Insulated-gate bipolar transistor, a n-channel metal-oxide-semiconductor field-effect transistor or a p-channel metal-oxide-semiconductor field-effect transistor. An independent claim is included for a method for operating an arrangement.
