ELECTRICAL ENERGY STORE, ELECTRICAL ENERGY STORAGE SYSTEM, METHOD FOR PRODUCING THE ELECTRICAL ENERGY STORE, AND MOTOR VEHICLE

摘要

The invention relates to an electrical energy store (1), comprising a battery cell module (10), in particular a lithium-ion battery cell module, and a sheath (40) made of an electrically insulating material that encloses the battery cell module (10). According to the invention, the sheath (40) has an opening (41) having a projection surface substantially corresponding to a cross-section surface of the battery cell module (10) running perpendicular to the projection direction. The invention further relates to an electrical energy storage system that has an electrical energy store (1) according to the invention and a cooling device. The invention further relates to a method for producing the electrical energy store and to a motor vehicle.
