Support Device for an Electrical Energy Store Having an Isolation Strip, And Electrical Energy Store

A support device for an electrical energy store for arrangement in a storage housing between at least two storage modules of the electrical energy store and for holding the storage modules, which can be fastened to both sides of the support device in the transverse direction, in the storage housing, includes: a beam for fastening to the storage housing, having a bearing face on which holding elements of the storage modules are to be placed; a clamping strip for arrangement on the bearing face of the beam and for clamping the holding elements of the storage modules; and fasteners for fastening the clamping strip to the beam. In an upper side of the clamping strip there are formed depressions which are arranged spaced apart from one another in the longitudinal direction of the support device and which are configured to receive the fasteners. The depressions form continuous channels in the transverse direction. An isolation strip is to be arranged on the upper side of the clamping strip and is designed to close the channels in order to prevent a thermal event of one storage module from being transmitted to another storage module located opposite in the transverse direction. The strip has two side parts which extend in the longitudinal direction and cover the depressions at the sides, and cover regions which cover the depressions on the upper side.
