NOVELTY - The module has prismatic storage cells (10) clamped between two end plates by tension rods. Storage cells series are separated from the end plates and the tension rods by an insulating jacket that completely encircles the storage cells series and comprises electrical insulation properties. The electrical insulation properties of the insulating jacket are formed such that the insulating jacket provides contact protection regarding voltage obtained by serially connecting the storage cells of the module. The insulation jacket is formed from two jacket halves, which are overlapped at facing ends.    USE - Energy storage module for a power supply device i.e. battery, of a motor car (claimed). Can also be used for an electric car or hybrid vehicle.    ADVANTAGE - The electrical insulation properties of the insulating jacket are formed such that the insulating jacket provides contact protection regarding the voltage obtained by serially connecting the storage cells of the module, so that the insulation jacket ensures high-voltage safety of the module, thus manufacturing the module in a simple and efficient manner without specific protection measures with regard to the electric shock protection. The prismatic storage cells are clamped between two end plates by the tension rods, so that displacement of components of the module can be prevented during manufacturing process, thus enabling better installation of the module in the motor car, minimizing movement of the storage cells within the module, and enhancing durable operability of the module. The provision of the storage cells allows functional separation of the cooling device and the power supply, thus achieving simple and economical construction of the module.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing an energy storage module for a power supply device of a motor car.
