Abstract
An electric-vehicle battery system includes a high voltage system with a plurality of connected rechargeable battery cells; a low voltage system with an operating voltage lower than an operating voltage of the high voltage system, the low voltage system supplying a battery system manager; and a real time clock configured to provide a system time to the battery system manager. The real time clock may be at least temporarily powered by the high voltage system.
