  "textContent": "The present disclosure provides an external cladding film, an energy storage device and an electrical equipment. The energy storage device includes an external cladding film and a housing. The external cladding film includes two side film sections. Each side film section has a first cut groove and a second cut groove. The first cut groove and the second cut groove both penetrate through the side film section along a thickness direction of the side film section, and penetrate through an outer edge of the side film section. A bottom surface of the first cut groove and a bottom surface of the second cut groove are both spaced from inner edges of the side film sections. Each side film section has a first oblique crease and a second oblique crease. A first free end of the first oblique crease intersects with a side surface of the first cut groove. A distance between the first free end and the bottom surface of the first cut groove is greater than 0. The use of external cladding film to cover the housing is less prone to misalignment, ensuring a consistency of the energy storage device and helping to improve a service life of the electrical equipment.",
