摘要

The present invention relates to the technical field of lithium batteries, and relates to a 48V compact battery pack based on a soft-packed cell having tabs on both sides. The present invention solves the problems of complicated structure, large space occupied and poor heat dissipation effect of an existing battery pack. The present invention comprises a front cover battery management device, an aluminum alloy shell, a battery module, and a sealing ring. The battery module is disposed in the aluminum alloy shell. The aluminum alloy shell is a hollow shell having an open end. The open end of the aluminum alloy shell is provided with the front cover battery management device clipped thereto. The sealing ring is provided on the connecting surface between the front cover battery management device and the aluminum alloy shell.
