An electrical energy store for the storage of electrical energy for a motor vehicle, includes a housing which delimits a receptacle space, storage cells which are arranged in the receptacle space for the storage of the electrical energy, and a line element, which accommodates a through-flow of a coolant fluid for cooling the energy store. The line element has at least one longitudinal region which is routed in the receptacle space and is constituted of a first material having a first melting temperature, and at least one outflow opening that terminates in the receptacle space. A closure element closes the outflow opening and is constituted of a second material, which differs from the first material and has a second melting temperature which is lower than the first melting temperature. The closure element is to be melted for the release of the outflow opening. The storage cells are constituted as solid-body accumulators.
