Abstract
A capacitive energy storage module (CESM) is provided under a floor panel of an electric vehicle. The CESM is a pack of capacitive energy storage cells (CESCs) which are themselves one or more capacitive energy storage devices (CESDs) comprising one or more metacapacitors. The CESM is arranged between a pair of right and left side members. The CESM is provided with a CESM case. The CESM case includes a tray member and cover member. Electric components are contained in the CESM case. Beam members made of metal are attached to the tray member. Both end portions of these beam members are supported by the side members. The tray member includes a resin and insert members made of metal provided inside the resin. The insert members include metal plates arranged on the front side and rear side of the electric components.
