Abstract: An electric energy store for installing into a motor vehicle includes at least two housing parts. A first housing part is not designed to receive storage cells and a second housing part is designed to receive all of the storage cells. The first housing part is designed to be installed in the motor vehicle as an upper housing part, and the second housing part is designed to be installed in the motor vehicle as a lower housing part. The first housing part can be closed by a removable first cover, and the second housing part is designed as a closed capsule with a non-removable second cover.

Abstract: A method is provided for impedance-controlled fast charging of a stored electrical energy source of a working device, in particular of a stored energy source in a vehicle. In the method: a variable characteristic of an impedance of the stored energy source is detected; a present charging current for charging the stored electrical energy source is set as a function of the variable characteristic of the impedance; the present charging current is temporarily reduced with a steep edge by temporarily connecting a resistive load to the stored energy source and feeding the load using the stored energy source; and a voltage response of the stored energy source to the steep edge is detected as the variable characteristic of the impedance of the stored energy source and is used as the basis for setting the present charging current.
