Embodiment Construction

[0022] refer to figure 1 , illustrates a schematic diagram of a battery module 10 configured to provide power to a battery electric vehicle or a hybrid vehicle according to an exemplary embodiment. refer to figure 1 , 2 and 4, the battery module 10 includes battery cells 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 47, 48, 50; frame members 60, 62, 64 , 66, 68, 70, 72, 74, 76; circuit board 80; interconnect members 90, 92, 94, 96, 97, 98, 100, 102, 103; and include exothermic reactive layers 110, 112, 114, 116 exothermic reaction layer. One advantage of the battery module 10 is that the module 10 utilizes an exothermic reactive layer that can be ignited with a laser beam during the manufacture of the module 10 to very quickly bond the cell terminals of the battery cells together and Cell terminals are bonded to associated interconnection members. An exothermic reactive layer refers to a layer that generates heat after being ignited.

Abstract

The present application relates to battery modules and methods for coupling cell terminals together. The battery module includes a first battery cell having a first cell terminal and a second battery cell having a second cell terminal. The battery module also includes an exothermic reaction layer having first and second sides. The first and second sides are disposed adjacent to the first and second cell terminals, respectively. The exothermic reactive layer is responsive to the laser beam in contact with at least a portion thereof and emits heat to form a coupling joint between the first and second cell terminals.

Description

Background technique [0001] A battery module has battery cells with cell terminals that are welded together. Furthermore, ultrasonic welding devices have relatively long cycle times for welding unit terminals together. Furthermore, the welding tool of the ultrasonic welding device must be sequentially moved to each set of unit terminals, which takes a relatively large amount of manufacturing time. Furthermore, the welding tool must be allowed to cool between each weld, which takes up an additional amount of manufacturing time. [0002] Accordingly, the inventors herein have recognized that there is a need for an improved battery module and method for joining together cell terminals of a battery module. Contents of the invention [0003] There is provided a battery module according to an exemplary embodiment. The battery module includes a first battery cell having a first cell terminal. The battery module further includes a second battery cell having a second cell termina...
