Abstract

The utility model discloses a vehicle which comprises a vehicle body, an energy storage system and a support frame, wherein the energy storage system comprises a plurality of battery packs, the battery packs are sequentially connected in the thickness direction of the battery packs, the support frame is respectively connected with the vehicle body and the energy storage system, and the support frame clamps the energy storage system in the thickness direction of the battery packs. Compared with the prior art, the scheme utilizes the gapless superposition of a plurality of battery packs by canceling the middle frame structure, and the support frame clamps the design of the energy storage system along the thickness direction, so that the problem of high accumulation of the traditional frame type steel structure is avoided while the stable connection of the energy storage system is ensured. The double-connection structure of the vehicle body and the energy storage system not only ensures the fixing reliability of the battery system, but also distributes load through a force transmission path in the thickness direction, thereby further reducing the influence of the structural height on the gravity center.
