A mobile charging apparatus is disclosed. The mobile charging apparatus includes a direct current electrical motor coupled to at least one wheel of a mobile equipment, the direct current electrical motor configured to generate an electrical power when the wheel is in motion and a battery contained in a compartment of the mobile equipment connected to a circuit connected to the direct current electrical motor and configured to receive the electrical power. The mobile charging apparatus further includes a charging port connected to the battery in a recessed area of the compartment, the charging port configured to receive power from the battery, the recessed area configured to receive an electronic device and the charging port includes a connector for charging the electronic device.

A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module.

The combined power supply contains an accumulator battery and a supercapacitor. It contains a universal battery module, made in the form of a metal box which is mounted to the frame of the electric bicycle, and in the middle of which is placed an accumulator battery with a charge protection unit connected to the active battery balancer. A supercapacitor connected to a supercapacitor converter/balancer that is coupled to a current sensor coupled to an overload protection unit of a universal module coupled to a downconverter. The active battery balancer is connected to the battery monitor and controller which is also coupled to the supercapacitor converter battery monitor, temperature sensor, and data exchange module.

A battery pack including: first and second battery contactors respectively having first ends electrically connected to positive and negative electrode terminals of a battery; first and second charging contactors respectively having first ends electrically connected to second ends of the first and second battery contactors; a second power connector of a charger having first and second output terminals respectively electrically connected to the first and second input terminals being connected to the first power connector; and a control unit configured to, when charging is being performed, diagnose a fault of each of the first charging contactor and the second charging contactor.

A holding fixture for fastening a mobile terminal to a module having fastening elements for attaching the holding fixture. The mobile terminal includes a charging coil for contactlessly charging an energy store. The holding fixture includes a window region and a support frame for holding the mobile terminal and for attachment to the module. The support frame extends about the window region. The window region is covered by a supported mobile terminal, when the holding fixture is attached to the module. The holding fixture includes a transmitter unit for generating a resonant inductive coupling with the charging coil. With the aid of a transmitting coil, the transmitter unit generates a resonant inductive coupling acting at least partially through the window region. Consequently, a holding fixture is provided, which includes a window region and has an improved efficiency in the charging of the energy store of a supported mobile terminal.

A wearable system, such as a footwear system, can employ a generator. The generator can be powered by human movement, such as movement of knee as a person walks or runs. When the knee resets, it can be desirable to have a relatively equal gear ratio to achieve near natural movement. Conversely, it can be desirable to have a high gear ratio when the knee pushes off to achieve high generator rotation to produce a high amount of power. This can be achieved with employment of a wearable planetary gear set configuration In practicing this wearable planetary gear set, torque can be provided from the source (e.g. human ankle joint) when power negative and not at other times during a movement cycle, meaning energy can be harvested from the walking motion without inducing additional burden to the device wearer.

This invention provides an enhanced electric vehicle battery powering and recharging system technology, particularly when the vehicle is moving or when wind or air comes in contact with the vehicle wind-power electric generator propeller system. The invention can be installed in partial or fully electric land, air, or water vehicles, to power or recharge the vehicle's battery system. This invention will extend a vehicle's travel distance before or without stopping and connecting to fossil fuel or other stationary rechargeable power sources. The vehicle's wind-powered electric generator invention is an additional battery charging technology that will support any partial or fully electric-powered vehicle. The invention can be installed in a partial or fully electric-powered vehicle as a hardware component and software program, without any interferences with existing vehicle electric battery charging systems.

An electric bicycle assembly for propelling a bicycle includes a bicycle that includes a first chain sprocket and pedals coupled to the first chain sprocket for rotating the first chain sprocket to propel the bicycle. A second chain sprocket is coupled to the first chain sprocket such that the second chain sprocket is rotated when the first chain sprocket is rotated. A generator is coupled to the bicycle and the generator is rotated to generate electrical energy when the pedals are pedaled. A motor is coupled to the bicycle and the motor is in mechanical communication with the rear wheel. The motor rotates the rear wheel when the motor is turned on for propelling the bicycle.

A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

A footwear system can employ a brake and/or a clutch, such as a one-way clutch, to convert human motion into usable electricity. The brake and one-way clutch can be used together, such as on opposite ends of a spring. During a storage phase, the brake can be engaged and the one-way clutch disengaged so the spring stores an energy. After the storage phase, the brake can be removed to initiate the release phase since the brake is not stopping the spring, but the one-way clutch allows the stored energy to be released.
