LiFePO₄ Battery Pack: A 3D Exploded View of Core Components

This is a 3D exploded-view diagram of a battery.

The LiFePO₄ battery pack consists of an aluminum shell, epoxy boards for insulation, and a sophisticated BMS. The black part is the battery’s outer casing, providing structural support and protecting the internal components. The middle section consists of battery cells, typically connected in series or parallel via busbars to facilitate current transmission. Lithium iron phosphate batteries are used for their high safety and long cycle life. The yellow part is an epoxy board, which provides electrical insulation, mechanical support, high-temperature resistance, and flame-retardant safety. Above the epoxy board, the green circuit board is the BMS (Battery Management System), responsible for functions such as voltage equalization, temperature protection, and communication. The BMS monitors real-time parameters like voltage, current, and temperature to achieve multiple protections, including overcharge, over-discharge, overcurrent, and overtemperature safeguards.

These are the main components of the battery.
