A method is provided for producing an energy supply unit for a vehicle having a housing and a stack, realized as a fuel-cell stack, battery stack or capacitor stack, arranged in the housing. The method includes providing the housing, including first and second tie-rod plates and first and second pressure-plate arrangements, wherein each pressure-plate arrangement is fastened to each tie-rod plate, arranging the stack between the two tie-rod plates and between the two pressure-plate arrangements, applying a bracing force to the two pressure-plate arrangements for the purpose of bracing the stack, and fastening at least the first pressure-plate arrangement to both tie-rod plates while the bracing force is being maintained upon the two pressure-plate arrangements. At least one pressure-plate arrangement includes a tolerance compensation system including an end plate securely connected to the tie-rod plates, a contact-pressure plate arranged between the end plate and the stack, and a positioning arrangement.
