Battery module supporting device and vehicle

Abstract

The invention discloses a battery module supporting device and a vehicle, and belongs to the technical field of vehicles. The battery module supporting device comprises a liquid cooling plate, a first bracket, a second bracket, a BMS bracket and a suspension cross beam; the first end of the BMS bracket is fixedly connected with the first bracket, the second end of the BMS bracket is fixedly connected with the second bracket, and the first bracket is opposite to the second bracket; the first end of the suspension cross beam is fixedly connected with the first bracket, and the second end of the suspension cross beam is fixedly connected with the second bracket; the first end of the liquid cooling plate is fixedly connected with the first bracket, and the second end of the liquid cooling plate is fixedly connected with the second bracket; and the two sides of the liquid cooling plate are fixedly connected with the BMS bracket and the suspension cross beam respectively. With the battery module supporting device of the invention adopted, the system integration level can be improved, the space required for arrangement is reduced, the structural stability is improved, and the flatness of battery cells in the middle of a battery module is ensured.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery module supporting device and a vehicle. Background technique [0002] Electric vehicle power battery system usually consists of battery module, thermal management system, BMS (battery management system, BATTERY MANAGEMENT SYSTEM), power distribution box and related electrical connections. As users continue to increase the mileage and safety requirements of electric vehicles, the double-layer battery module structure can provide greater power, and the battery module structure that supports liquid cooling can improve the temperature adaptability of the battery module structure during operation and security. [0003] However, in the prior art, the structure of the battery module supporting liquid cooling is to support the battery module through the liquid cooling plate, and the liquid cooling plate can only support the battery module with a length of less than 600mm. If ...
