Provided are a battery holder, a power transfer device, an electric vehicle and an installation method for electric vehicle. The battery holder includes a fixing bracket, a lock mechanism and a plurality of supporting devices, the lock mechanism is fixed on the fixing bracket, the supporting device is fixed on one side of the fixing bracket facing the battery pack. The electric vehicle includes the battery holder as described above. In the present invention, the weight of the battery pack can be simultaneously distributed on the plurality of supporting devices and the lock mechanism, the force of the fixing bracket is more evenly, the force applied by the battery pack to the lock mechanism is reduced, the force concentration of the lock mechanism on the fixing bracket is prevented, the service life of lock mechanism is improved, and improve the connection strength between battery pack assembly and battery holder.
