Determination of an unbalanced load in a high-voltage system and reaction to the same

A method, comprising:

• determining first information about an electrical unbalanced load of a vehicle having an at least partially electrified drive train having at least one high-voltage system, by
• determining a value characterizing an energy quantity of at least one Y capacitor of the high-voltage system, wherein the value is a voltage of the high-voltage system, a partial voltage of the high-voltage system, value related to the partial voltage of the high-voltage system, a relationship of voltages of the high-voltage system, or a relationship of isolation resistances of the high-voltage system;
• providing a first threshold value related to a capacitance of the at least one Y capacitor;
• and
• determining the first information about the electrical unbalanced load by comparing the determined characterizing value with the provided first threshold value;
• and
• introducing first and second correction resistances, depending on the determined first information, to reduce an energy quantity of one of the at least one Y capacitor that affects the unbalanced load, wherein the introducing of the first and second correction resistances comprises manually introducing the first correction resistance into a first socket of the at least one high-voltage system and manually introducing the second correction resistance into a second socket of the at least one high-voltage system.
