A drive wheel for a wheelchair includes a wheel hub motor, wherein the wheel hub motor has a connecting structure and an output end at a side that is opposite to the connecting structure. The output end is engaged with a wheelchair wheel. The wheel hub motor is surrounded by a receiving case. The receiving case has a control terminal block that is electrically connected to a battery module and a control board which are disposed in the receiving case. Since a portion of the battery module is disposed in the receiving case, the battery module of the wheelchair are separately disposed in drive wheels and the main body of the wheelchair, so that the weight of the battery module is distributed, thereby reducing the weight of the main body and keeping the drive wheel liftable. With such design, the wheelchair could be easily transported and assembled.

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 vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and an electric energy system. The electric energy system includes a first battery pack positioned forward of the rear axle and supported by the chassis and a second battery pack positioned separate from the first battery pack rearward of the rear axle. An uppermost periphery of the first battery pack is spaced a distance below a top of the chassis and above a bottom of the chassis. At least a portion of the first battery pack extends lower than the bottom of the chassis. At least a portion of the second battery pack is positioned at an elevated height relative to the first battery pack such that an uppermost periphery of the second battery pack is positioned above a point at which a body assembly contacts the top of the chassis.

An electrified vehicle includes a chassis, a cab coupled to the chassis, a body assembly coupled to the chassis, and an energy storage system. The body assembly is positioned behind the cab with a space defined therebetween. The energy storage system is positioned within the space between the cab and the body assembly. The energy storage system includes a housing and a plurality of battery cells disposed within the housing. The housing is coupled directly to the chassis and extends upward from the chassis such that a portion of the housing is positioned above at least a portion of a roof of the cab.

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 motorized stretcher system designed for efficient and secure transport of injured individuals across uneven surfaces. The system comprises a litter secured to a suspension frame, which is connected to a central hub housing a motor, tire, brake rotor, and caliper. The litter is contoured to safely hold an injured person, with adjustable ratchet straps and side rails providing additional security. The motor, controlled via a throttle and directional switch, drives the tire to propel the stretcher in multiple directions. A suspension system, incorporating multiple dampers, absorbs vibrations and stabilizes the litter across uneven surfaces. Powered by a battery assembly, the motor provides sufficient torque to traverse challenging environments while ensuring smooth and controlled transport.

A method for protecting the battery of a wheel unit fitted to a wheel of a motor vehicle. The motor vehicle includes a central processing unit and the wheel unit includes at least a first sensor capable of measuring and of supplying an operating parameter of the wheel unit and a battery which supplies the wheel unit with power. The method including that the wheel unit transitions from an operational state to a non-operational state when the operating parameter reaches a predetermined upper threshold, and the wheel unit transitions from the non-operational state to the operational state when the operating parameter reaches a predetermined lower threshold.

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 includes a frame, an axle coupled to the frame, a cab coupled to the frame, a body assembly coupled to the frame and defining a refuse compartment, a lift assembly configured to engage and lift a refuse container, an electric motor coupled to the axle, and an electrical energy system configured to provide electric power to the lift assembly and the electric motor. The body assembly is positioned behind the cab. The electrical energy system includes a first set of one or more battery cells positioned vertically above at least a portion of the cab.
