On-board power system for vehicle, has electrical energy storage device that is electrically connected with accumulator units according to total output voltage value corresponding to predetermined input voltage value

摘要

A vehicle electrical system (B2) has an electrical energy storage device (7) that is electrically connected in series with a number of electrically interconnected accumulator units (7.1-7.4) according to the total output voltage value corresponding to predetermined input voltage value. A vehicle electrical system (B1) is electrically connected with an electrical power supply unit of energy storage device, and with the accumulator units. The energy storage device is electrically connected according to total output value and predetermined input voltage value. An independent claim is included for a method for operating on-board power system for vehicle.
