Abstract

The present invention provides a battery box and a vehicle, the battery box comprises a box body, batteries, an insulating film and a 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. TheA₁,A,L₁,ρ₁,L₂andρ₂meet a following relationship:L1A1⋅ρ1⋅L2A−A1⋅ρ2L1A1⋅ρ1+L2A−A1⋅ρ2≥10MΩ.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, it ensures the bonding strength between the battery and the box body. Meanwhile, it makes a covering area of the insulating film on the battery meet the requirement of the insulating strength, thereby ensuring the safety performance.
