METHOD FOR DETERMINING PERFORMANCE INFORMATION OF A BATTERY OF A MOTOR VEHICLE ON-BOARD POWER SYSTEM THAT IS CONNECTED TO A DIRECT CURRENT CONVERTER, AND MOTOR VEHICLE
The invention relates to a method for determining performance information of a battery (6) of a motor vehicle on-board power system (2) that is connected to a direct current converter (3), wherein the direct current converter (3) is actuated to apply at least one alternating current having a specified frequency to the on-board power system (2) and the performance information is derived from at least one first electrical parameter on an output (12) of the direct current converter (3) on the on-board power system side and at least one second electrical parameter describing the reaction of the battery (6) to the applied alternating current.
