A concrete mixer vehicle includes a chassis, a tractive assembly coupled to the chassis and configured to propel the concrete mixer vehicle, a mixing drum rotatably coupled to the chassis, and an electromagnetic device configured to convert electrical energy to mechanical energy to drive the tractive assembly. In a first configuration, a first battery module is removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device, and in a second configuration, the first battery module is removed from the chassis and replaced with a second battery module, the second battery module removably coupled to the chassis and configured to provide the electrical energy to the electromagnetic device.

An electric work vehicle includes a vehicle body having traveling wheels, a traveling motor capable of driving the traveling wheels, and a battery unit having, at one end portion thereof, a pair of left and right leg wheels, the battery unit being detachably attachable to a battery storage section of the vehicle body and being capable of supplying electric power to the traveling motor. The battery unit, when detached from the battery storage section, is posture-switchable between a flat placement state in which the leg wheels and the other end portion thereof opposite to the side on which the leg wheels are located are placed in contact with the ground surface and a tilted posture in which the battery unit can stand on its own with the other end portion thereof being located higher than the leg wheels.

Provided are: a battery case structure for electric-powered vehicles wherein restrictions on the size or the like of a battery mountable on electric-powered vehicles are alleviated, and the attaching/detaching operability is improved; and an electric-powered vehicle. A battery case structure is equipped with: a cover member which is disposed below the center in the longitudinal direction of a main frame and rocks in the transverse direction of the vehicle; and a lower frame which is connected to the main frame, and is disposed in such a manner as to go around the bottom of the cover member. A battery is detachably inserted into the cover member through the detachable opening separated from the main frame. When the detachable opening is brought close to the main frame, the battery housed in the cover member is supported on the lower frame and housed between the lower frame and the main frame.

An electric vehicle includes a frame unit and a vehicle body cover unit. The frame unit includes tread boards extending toward a rear side of a vehicle body. The tread tubes are arranged in a left and right pairwise form as a left tread tube and a right tread tube. The vehicle body cover unit includes a thread board shielding the left tread tube and the right tread tube. A battery box that receives and holds a battery is shaft-supported on the frame unit. The battery box has two sides provided with support shafts. The battery box is shaft-supported on the frame unit by the support shafts in a left-right direction. The battery box is rotatable about a rotation center defined by the support shafts in a front-rear direction to an open position or a storage position so as to facilitate removal of the battery from the battery box.

A powered vehicle includes a chassis having a front end and a rear end, and at least one front wheel and at least one rear wheel for supporting the chassis. The at least one front wheel defines a front axle and the at least one rear wheel defines a rear axle. A first portion of the vehicle defines an interior in which at least one seat is located. A second portion of the vehicle is located outside of the interior. The first and second portions are at least partially separated by a wall. A power system for propelling the vehicle is located in the second portion, where the power system includes a HV battery for producing electrical power to propel the vehicle. The battery is coupled to the chassis and located in the second portion.

An electric vehicle includes a frame unit and a vehicle body cover unit. The frame unit includes tread tubes extending toward a rear side of a vehicle body. The tread tubes are arranged in a left and right pairwise form as a left tread tube and a right tread tube, and a first cross tube and a second cross tube connected to the tread tubes. The vehicle body cover unit includes a thread board shielding the left and right tread tubes. A battery box that receives and holds a battery is shaft-supported on the frame unit. The battery box is shaft-supported on the frame unit by support shafts in a vehicle body front-rear direction. The battery box is rotatable about a rotation center defined by the support shafts in a vehicle body left-right direction to an open position to facilitate removal of the battery from the battery box.

An opening control structure of an electric vehicle battery box is provided. An electric vehicle at least includes a frame unit and a vehicle body cover unit that covers the frame unit. The frame unit shaft-supports a battery box thereon. The battery box receives and holds therein a battery that supplies electrical power for driving the electric vehicle. The battery box is provided with an operation device that sets the battery box at an open position or a storage position. The operation device is electrically connected to an operation controller. The operation controller is electrically connected with a verifying unit. The verifying unit is put into operation by a to-be-verified unit or through sensing. As such, easiness of lifting and removing a battery and burglarproofness are improved.

An embodiment is directed to a battery module mounting area of an energy storage system. The battery module mounting area includes a first set of battery module compartments arranged along a first longitudinal side of the battery module mounting area, and a second set of battery module compartments arranged along a second longitudinal side of the battery module mounting area. Each battery module compartment in the first and second sets of battery module compartments includes an insertion-side through which a battery module is configured to be inserted into the battery module compartment and/or removed from the battery module compartment. The insertion-side of each battery module compartment in the first and second sets of battery module compartments is configured to be closed via an insertion-side cover to form a battery housing with a closed compartment profile that is characterized by each battery module compartment being sealed from at least one other battery module compartment in the battery housing.
