Abstract: This disclosure provides a power cabinet. The power cabinet includes M modules, N plug-in components, and N locking apparatuses. The M modules are sequentially stacked from top to bottom. The N plug-in components are configured to lead out a power line and/or a signal line. A pth module and a (p+1)th module are electrically connected by using a pth plug-in component, the pth module and the (p+1)th module are connected by using a pth locking apparatus, M, N, and p are all integers, M?3, N=M?1, 1?p?M?1, at least one of the M modules is a battery management module, and remaining modules of the M modules are battery modules.
