Description

Technical Field

[0001] This invention relates to a battery connection module, including a battery connection component of the battery connection module and a battery connection system including the battery connection component. Background Technology

[0002] In existing technologies, the battery integrated busbar system (or battery connection system) is a core component of electric vehicles, and its manufacturing process affects battery performance and safety. Currently, the battery integrated busbar system primarily uses a flexible printed circuit board (FPC) as the transmission medium. This FPC integrates voltage acquisition, temperature acquisition, overcurrent protection, cell electrical connection, and structural support functions. This highly integrated FPC is expensive, leading to increased costs.

[0003] Furthermore, in existing technologies, busbars, temperature sensors, and fuses are all integrated onto flexible printed circuit boards (PCBs). Busbars and temperature sensors are typically soldered directly onto the PCB, while fuses are formed directly onto the PCB through an etching process. Therefore, in existing technologies, when a temperature sensor or fuse fails, the entire PCB becomes unusable and needs to be replaced, resulting in high repair and maintenance costs.
