Abstract: A battery pack includes a housing and multiple electrode core strings electrically connected to each other and disposed in the housing. The housing includes a housing body which includes sub-housings connected to each other. A sub-housing includes at least one reinforcing plate and a top plate and a bottom plate oppositely arranged in a first direction. The reinforcing plate is arranged between and is connected to the top plate and the bottom plate, and divides an interior of the corresponding sub-housing into multiple accommodating cavities. At least one accommodating cavity includes at least one electrode core string which includes electrode core assemblies connected and arranged in a second direction. The electrode core assemblies are disposed in an encapsulation film. A length of the electrode core string extends in the second direction. The housing includes a mounting component that is configured to be connected and fixed to an external load.
