Abstract
A method for operating a charging device of an electrical energy store for a motor vehicle, wherein a dedicated rectifier device for generating a charging voltage for the electrical energy store is associated with each phase of an AC power supply, includes determining for each rectifier device a usage variable descriptive of its prior usage for charging the electrical energy store; when performing a multi-phase charging operation with the charging device, using for each phase a corresponding rectifier device for generating the charging voltage for the electrical energy store; and when performing a single-phase charging operation with the charging device, using the hitherto most underused rectifier device for generating the charging voltage for the electrical energy store based on the usage variable.
