A bonded soft pack battery module

Abstract

The invention discloses an adhesive soft pack battery module, which comprises a battery module body, a casing, a negative side plate, a positive side plate, a left end plate, a right end plate and a bottom plate. The battery module body is composed of It is composed of multiple battery modules stacked vertically. The multiple battery modules are bound and fixed with adhesive tape to form a battery module body with an integral structure. The negative side plate and the positive side plate are respectively covered at both ends of the battery module body. The side end plate is connected to the outside of the negative side plate, the right side end plate is connected to the outside of the positive side plate, and the case covers the upper end surface and the front and rear end surfaces of the battery module body. The present invention adopts the casing, the negative side plate, the positive side plate, the left end plate, the right end plate and the bottom plate to cover and protect the battery module body, thereby ensuring the integrated connection structure of the battery module, and the connection method It is simple, fast, and the structure after connection is stable.

Description

technical field [0001] The invention relates to the field of battery modules, in particular to an adhesive soft pack battery module. Background technique [0002] With the increasing environmental pollution, the use of traditional fuel vehicles will become less and less, while new energy electric vehicles with no pollution and low noise during use are becoming more and more popular with governments and people of all countries. With the support of policies and the improvement of technology, the proportion of new energy vehicles in the vehicle market is also increasing. But at the same time, the energy density of the battery is not high, and the group efficiency of the battery system is low, which leads to the short mileage of electric vehicles and cannot adapt to the use of continuous long mileage. These directly affect the promotion and use of new energy vehicles. In order to solve this problem, battery modules have begun to be used in the field of electric vehicles. Howev...
