The AT WILL 7 POWER Fuelless Generator operates starting with a small or large rechargeable 12 v battery or batteries, d/c capacitor or capacitors, a/c capacitor or capacitors, dc to ac inverter or inverters, or ac to dc converter or converters, or dc to ac inverter and ac to dc converter or nether dc to ac inverter or ac to dc converter, dc electric motor, a/c or d/c electric motor or motors, alternator or alternators, generator head or generator heads, tapered cone generator or tapered cone generators, generator or generators, 12 volt radiator fan or radiator fans, belt and pulley system, tension pulley or tension pulleys or nether, and a few other components to make it a high efficiency long lasting fuelless electric generator. The noise level on this generator is very low and the weight is lighter then most generators on the market right now. Because of it's zero pollution it can operate indoors continuously with out generating a lot of heat. This is a stand alone system and has no support from wind, or sun. This generator comes in different sizes, voltages and watts for homes and commercial use.

Devices, systems, and methods may use a low current power source to charge an intermediate storage unit, providing sufficient electric power to perform various device functions. A voltage of the intermediate storage unit may be monitored using a voltage monitoring circuit, and a primary storage unit may be charged using current from the intermediate storage unit when the voltage of the intermediate storage unit meets a threshold.

A power distribution system 100 is installed in an aircraft, and comprises: a first DC power supply unit 10 including a generator 11; a second DC power source unit 20 including a battery 30, a step-up/down converter 41, a voltage sensor 43, and control unit 44; and a diode 50. When the voltage sensor 43 does not detect regenerative power, the control unit 44 executes a running power processing mode in which generated power generated by the first DC power supply unit 10 is supplied to an electric actuator 80 while charging and discharging the battery 30 using the step-up/down converter 41 so as to keep a charge rate A of the battery 30 within a predetermined range. When the voltage sensor 43 detects regenerative power, the control unit 44 executes a regenerative power processing mode in which the battery 30 is charged with the regenerative power using the step-up/down converter 41.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs sequentially provide power to the riding lawn mower.

One embodiment is a system comprising an internal combustion engine including an output shaft, a pulley system structured to be driven by the output shaft, a first alternator and a second alternator structured to be driven by the pulley system, and an electromagnetic clutch integrated within one of the pulley system, the first alternator and the second alternator and structured to selectably couple and decouple at least one of the first alternator and the second alternator from the output shaft. The system includes a controller in operative communication with the internal combustion engine system and structured to evaluate power demand and power production capability parameters of the system and to control the electromagnetic clutch to engage or disengage in response to the evaluation.

The present disclosure relates to the technical field of charging. A terminal and a battery charging control device and method are provided. The battery charging control device including a battery connector, a main control circuit and a quick charging switch circuit is adopted. During the regular charging or the quick charging, the main control circuit performs a data communication with the external power adapter via the communication interface, and obtains a charging voltage and a charging current for the battery; if the charging voltage is greater than a voltage threshold and/or the charging current is greater than a current threshold, the main control circuit sends a charging switch-off instruction, such that the controller controls the communication interface to switch off; if the charging voltage is less than or equal to the voltage threshold and the charging current is less than or equal to the current threshold, the main control circuit continues to obtain the charging voltage and the charging current.
