Embodiment Construction

[0038] The technical solution of the present invention will be further described below through one of the specific implementation manners and in conjunction with the accompanying drawings.

[0039] Cooperate Figure 1 to Figure 4 As shown, the lithium-ion battery module of lightweight design for vehicles provided by the present invention includes a plurality of battery cells 4, and these battery cells 4 are fixed in their respective corresponding battery cell fixing plates 12, and these battery cells are fixed After the boards 12 are assembled with each other, they are connected by several sets of fixing straps 13 to form a battery module. The upper cover 1 is fixed on each battery cell fixing plate 12 by screws 2 . Baffles 7 are also set on both sides of a battery module; a battery module management controller 8 (LECU) is set on the baffle 7 to collect the voltage and temperature of the battery cells 4 in the battery module, and control the battery through the program. The ...

Abstract

The invention relates to a light-weight lithium-ion battery module for vehicles. A plurality of single batteries are respectively fixedly adhered in a plurality of corresponding single-battery fixing plates; an insulating mat is arranged between two adjacent single batteries, and the single batteries are in series connection or in parallel connection with one another in a laser welding way; after two adjacent single-battery fixing plates are assembled in an anti-staggered way, an upper cover of the battery module is connected with the top of each single-battery fixing plate, then the single-battery fixing plates which are assembled, a left baffle plate and a right baffle plate are fixed through a bandage, and a battery module management controller for collecting the parameters of the single battery and controlling an early warning is arranged on the baffle plates. A battery module shell adopts a heat-conduction plastic structure, the weight is reduced by about 20 to 40 percent compared with that of the module structure with the metal shell, the investment cost of the battery module is low, an advanced adhesion technology is adopted, and the light-weight lithium-ion battery module has the advantages that the structure is simple, the safety is high, the cooling structure is simple and variable, automatic operation and production are easy to realize, the size of the module can be flexibly designed according to the application situation, etc.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a lightweight lithium-ion battery module for vehicles. Background technique [0002] The lithium-ion battery module is installed in the fixed frame of the system as an integral part of the vehicle power source battery pack system. Most of the battery modules currently on the market are complex in structure, difficult to disassemble and difficult to install. Some modules with cooling structure design have complex structures, mostly use metal heat conduction, and the battery modules are of high quality. The battery module designed by the Chinese patent application No. 201120498475 has an integrated cooling structure design, and the heat is exported through the metal frame, but it has many structural parts and the metal frame has a large mass. Contents of the invention [0003] The object of the present invention is to provide a battery module with lightweight design for...
