The invention relates to a method for securing a high voltage on-board power supply (14) of a motor vehicle (10) for repair and/or maintenance of the motor vehicle (10). The problem addressed by the invention is that of securing the high-voltage on-board power supply by technical means instead of procedural measures. For this purpose, the energy inflow of the energy supply unit (12) is blocked during or after a voltage disconnection of the high-voltage on-board power supply (14), in which an energy inflow of an energy supply unit (12) to the high-voltage on-board power supply is interrupted. Additionally or alternatively, at least one other energy inflow (16, 20, 32, 34, 38) is blocked, wherein the at least one other energy inflow (16, 20, 32, 34, 38) is designed in order to supply energy from a further energy source (22) to the high-voltage on-board power supply (14).
