Abstract

The invention relates to a square battery module structure comprising a box body, a cover plate, a battery pack composed of a plurality of square batteries arranged in a row and mounted in the box body, an overload protection block and a plurality of power connection blocks. Each square battery is provided with a positive electrode and a negative electrode. The negative electrode of a square battery is connected to the positive electrode of the square battery behind through the overload protection block or a power connection block. The overload protection block includes: two connecting blockshaving the same cross sectional area as that of the power connection blocks, and an overload protection member having both ends connected to the opposite ends of the two connecting blocks one to one.The cross sectional area of the overload protection member is less than the cross sectional area of the connecting blocks. According to the square battery module structure, the square batteries are connected by the overload protection block or the power connection blocks, and the overcurrent area is reduced by the overload protection member. When the current is abnormally increased, the overload protection member is quickly fused so as to quickly and sensitively achieve overload protection for the battery module.

Description

technical field [0001] The invention relates to the field of lithium ion batteries, in particular to a square battery module structure. Background technique [0002] The power battery is the core component of an electric vehicle and provides the power required for the entire vehicle. The power battery is generally composed of multiple battery modules. The power battery is divided into square, cylindrical and soft pack shapes according to different production processes. The battery pack has the advantage of saving space; when the power battery is overloaded during use, it will generate overload and heat. Long-term overload will reduce the insulation level and cause safety hazards, and even burn the line, so the power battery needs to be overloaded. The structure of the protector can be It is understood from the utility model of Chinese patent application number: 99201081.0, which discloses an overload protector for automobile batteries; the traditional overload protector that...
