    摘要: An energy storage system for a motor vehicle is provided, including an electric machine, which can be operated at least as a generator, for generating a generator current; a vehicle electrical system battery, which is connected to the electric machine in parallel; a capacitor unit, which is connected to the electric machine in parallel; and a controller for controlling the electric machine. The controller is configured such that if the vehicle is in the boost or braking operating mode, the battery of the vehicle electrical system is charged with a maximum battery charging current, whereas in all other cases the battery of the vehicle electrical system is charged by a battery charging current that is adjusted as a function of the charge state of the battery of the vehicle electrical system. Therefore, in order to adjust the battery charging current as a function of the charge state of the battery of the vehicle electrical system, three different charge states are considered.

    摘要: A system and method for supplying voltage to electrical loads in the onboard electrical system of a motor vehicle are provided. The onboard electrical system consists of at least two onboard electrical system regions. The first onboard electrical system region has an electric generator, a vehicle battery, as well as one or more first electrical loads. The second onboard electrical system region has a double-layer capacitor or a so-called supercap and one or more second electrical loads. Between the two onboard electrical system regions, a blocking device is provided, in particular, a semiconductor diode or a power switch, which permits a current flow from the first onboard electrical system region into the second electrical system region and largely prevents a reverse current flow from the second onboard electrical system region into the first onboard electrical system region. The output voltage of the electric generator is raised and the supercap is charged when a first threshold value of the electric voltage in the second onboard electrical system region is undershot.
