[0002] A battery module refers to an energy storage device that fixes and connects multiple small batteries through appropriate connectors and positioning clamps to provide larger capacity and higher voltage. This combination can increase energy density, power supply time and power output to meet the needs of different applications.

[0003] In traditional processes, welding is often used to connect multiple small batteries into one. If a single small battery is damaged during use, it is easy to cause the entire battery module to malfunction, making replacement and maintenance difficult.
