Battery and energy storage equipment

The utility model provides a battery and energy storage equipment. The energy storage equipment comprises a cabinet body and the battery. The cabinet body is provided with a containing space, and the battery is arranged in the containing space. The battery comprises a box body and an electric energy transmission set, the electric energy transmission set is arranged on one side face of the box body in the first direction, the electric energy transmission set comprises at least two power connection ends arranged in the second direction, the first direction is perpendicular to the vertical direction, and the second direction intersects with the first direction. According to the battery and the energy storage equipment provided by the embodiment of the invention, the space occupied by the electric energy transmission group in the first direction can be reduced under the condition that the battery rate and current requirements are met. When the cabinet body provides a fixed accommodating space, the space occupied by the power connection end is reduced, the size of the box body can be larger, and a larger space in the box body can be used for placing the single batteries, so that the space in the cabinet body can be effectively utilized, and the energy value of the batteries is improved.
