Patent ID: 11128009

Abstract:
The present disclosure provides a battery box, the battery box comprises a box body, batteries, an insulating film and an adhesive. Each battery comprises a case. The insulating film covers the case of each battery and is provided with an opening. The adhesive is provided between the battery and the box body. The σ1, σ2, A1 and A meet a following relationshipThe insulating film ensures the insulation performance, and because the insulating film is provided with the opening, a portion of the adhesive bonds the case to the box body at the opening, a portion of the adhesive bonds the insulating film to the box body at the outside of the opening, therefore the bonding strength between the battery and the box body is improved, thereby improving the overall strength. Moreover, because σ1, σ2, A1 and A meet the above relationship, the battery box ensures the safety performance.
