  • Method for charging an energy storage element of a vehicle using a modular charging apparatus with high overall efficiency
    Patent number: 11117485
    Abstract: A method for charging an energy storage element of a vehicle using a charging apparatus which provides a charging current (IL) and a charging voltage (U) at an operating point. The charging apparatus has a plurality of energy supply modules connected in parallel, having the following method steps: in an optimization step, a distribution of the charging current (IL) to the energy supply modules connected in parallel, in the case of which the charging apparatus has a maximum overall efficiency, is respectively determined for a plurality of predefined operating points; in a charging step which follows the optimization step, a distribution of the charging current (IL) to the individual energy supply modules of the charging apparatus, in the case of which the charging apparatus has a maximum overall efficiency, is selected on the basis of a predefined charging current (IL) and a predefined charging voltage (U).
