A work equipment battery case that stores a battery cell for driving a battery powered work equipment, the battery case includes: a plate-like bottom on which the battery cell is placed; and a plate-like side formed to project from the bottom, and arranged at an outside of the battery cell placed on the bottom, wherein a mass of a part of the side is larger than a mass of the other part of the side.

A vehicle body has, in a state in which a battery unit is not installed, a frame configuring a part of the lower surface of the vehicle body. A vehicle battery unit installation apparatus for installing a battery unit in the lower part of the vehicle body includes: a striker device configured to be secured to the vehicle body and a locking device secured to the battery unit. The striker device includes a base plate and a striker secured to the base plate. The striker has a support part capable of supporting a load. The locking device is capable of securing the support part. The base plate is configured to be secured to the frame. The striker has ends secured to the base plate such that the support part is located below the frame.

An electrical vehicle including a vehicle body, a passenger compartment, a chassis supporting the passenger compartment, a plurality of wheels and at least one electrical motor for driving the wheels. A battery compartment of the vehicle is configured to removably mount therein a plurality of more than two rechargeable batteries which are movable into position in the battery compartment by a battery conveyor system which has a battery access opening through which batteries are installed or removed, one by one, to and from the battery compartment. In the battery compartment, a connection mechanism effects the needed mechanical and electrical connections. An overall control system controls the conveyor system and the connection mechanism to enable rapid replacement of the removable batteries, whereby an electrical vehicle can be instantly driven, even after its batteries have been discharged by a replacement of the discharged batteries and the installation of freshly charged batteries.

Disclosed is a battery unlocking control method, a battery locking control method and an electric vehicle battery swapping control method. The battery locking control method comprises the following steps: moving the battery to the fixing base to enable the lock shafts to enter the lock slots; after the lock shafts enter the lock slots, detecting the locations of the lock shafts, and moving the battery until the lock shafts arrive at locking locations; and with the lock tongues falling, snapping the lock shafts into the lock slots. By providing various location detection components, the battery is accurately located and locked when being loaded into a fixing base, and then accurately located and unlocked when being removed from the fixing base, thereby achieving full-automatic control during swapping of the battery and improving the swapping speed and success rate of the battery.
