摘要
A method is provided for coupling at least one secondary energy source to an power supply network, in particular an on-board vehicle power supply, wherein a load is connected with a primary energy source having a first voltage characteristic. The at least one secondary energy source has a second voltage characteristic which has an operating voltage range overlapping with the first voltage characteristic. The primary energy source and the at least one secondary energy source can be connected via a power switching device to a node point of an intermediate circuit of the power supply network, to which the load is also connected. Before connecting a secondary energy source, the current drawn by the load is regulated such that the voltage connected to the node point of the intermediate circuit corresponds to a no-load voltage of the secondary energy source to be connected or is around the no-load voltage in a specified voltage range. In the case that the voltages correspond or if the voltage connected to the node point lies in the specified voltage range, the secondary energy source is electrically conductively connected to the node point via the power switching device. The current required by the load is regulated to the corresponding value, wherein the load is supplied from the primary and the secondary energy source.
