A refuse vehicle includes a chassis, a body assembly, and battery cells. The body assembly is coupled to the chassis and defines a refuse compartment. The battery cells are positioned between the body assembly and the chassis.

A refuse vehicle includes a frame, a cab coupled to the frame and positioned at a front end of the refuse vehicle, a body assembly coupled to the frame and defining a refuse compartment, the body assembly positioned behind the cab, and an electrical energy system configured to provide electric power to drive one or more wheels of the refuse vehicle, the electrical energy system comprising a first set of one or more battery cells and control hardware, the electrical energy system detachably coupled to the frame at a first position between the cab and the body assembly.

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, and an electric energy system, the electric energy system including one or more battery cells and control hardware, the electric energy system detachably coupled to the body and configured to be accessed by a door in the body, and wherein the one or more battery cells of the electric energy system are replaceable.

A wheel assembly includes an attachment module, a motor module, a battery module, and a wheel. The wheel is rotatably coupled to the attachment module about a rotational axis of the wheel. The attachment module has a plurality of coupling elements, and the motor module and the battery module each releasably couple to one of the coupling elements. The wheel extends around the attachment, motor, and battery modules. The motor and battery modules are identically shaped in a direction along the rotational axis.

A fuel cell assembly is mounted on a vehicle via a mounting portion. The fuel cell assembly includes a first fuel cell unit, a first frame portion on which the first fuel cell unit is mounted and fixed, a second fuel cell unit, a second frame portion on which the second fuel cell unit is mounted and fixed, and a connecting portion that connects the first frame portion and the second frame portion such that the second fuel cell unit is located above the first fuel cell unit.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles vet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

Space-saving in an automobile or the like provided with a battery is achieved. Design flexibility of an automobile or the like can be improved. An electric power control method or an electric power control system capable of utilizing electric power efficiently is provided. It is an electric power control system of an automobile including a car body, a first battery, a second battery, and a control unit. The control unit obtains states of charge of the first battery and the second battery, determines whether or not a difference between remaining capacities of the first battery and the second battery exceeds a predetermined value, and controls transmission of electric power between the first battery and the second battery, in the case where the difference in the remaining capacities exceeds the predetermined value, to be made such that the remaining capacities are close to each other.
