Abstract: The present disclosure provides a battery pack and an electric vehicle. The battery pack includes a housing and multiple electrode core strings electrically connected to each other and arranged in the housing. The housing includes a housing body. The housing body includes multiple sub-housings connected to each other. At least one sub-housing is provided internally with at least one reinforcing plate. Each of the sub-housings includes a top plate and a bottom plate oppositely arranged in a first direction. The reinforcing plate is arranged between the top plate and the bottom plate. The at least one reinforcing plate 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 is provided internally with at least one electrode core string. Each of the electrode core strings includes multiple electrode core assemblies sequentially arranged in a second direction and connected in series. The electrode core assemblies are packaged in a packaging film. A length of the electrode core string extends in the second direction. The housing is provided with a mounting component, and the mounting component is configured to be connected and fixed to an external load.
