摘要
A system for determining a voltage out-of-range high condition of a battery module is provided. A microcontroller determines first, second, and third voltage values from first, second, and third voltage sensors, respectively, coupled to first, second, and third battery cells, respectively; and determines a battery module voltage value based on a fourth signal. The microcontroller sums the first, second, and third voltage values to obtain a battery module high voltage sum value. The microcontroller generates a first control signal to induce a contactor to transition to an open operational position to electrically decouple the battery module from an electrical load, if a difference between the battery module high voltage sum value and the battery module voltage value is greater than or equal to a battery module voltage out-of-range high error value.
