A method and apparatus for removing the sulfation from the plates of the battery and driving the sulfate crystals back into the electrolyte solution without overheating the battery is presented. The present invention includes a rotary magnetic hub and coil assembly to produces a unique output not found in other charging systems on the market. The battery desulfation method and apparatus of the present invention is self-adjusting to the battery, regardless of voltage and works by removing the sulfate crystals from the plates of lead acid batteries. As a result, the normal life of the average battery may be greatly extended. Heavily sulfated batteries may be brought back to working condition. When used for short durations for healthy batteries, the present invention keeps the sulfate crystals off the plates and in solution to extend the working life of the battery.

A method and system for managing an automotive alternator are described for a vehicle having an internal combustion engine. The alternator is controlled by an electrical control unit (ECU) designed to facilitate electrical and mechanical coupling of the alternator to a battery. The ECU receives signals from a battery charge sensor to: determine a battery charge level between: BC1 (corresponding to a fully charge condition); BC2 (corresponding to a working charge level); and BC3 (corresponding to a low charge); and acting on the alternator such that: at level BC1, the alternator is disconnected electrically and mechanically; at leve BC3, the alternator is connected electrically and mechanically; and level BC2, the alternator is coupled mechanically when the vehicle movement speed is greater than a predetermined value (V.sub.Lim) and when the engine is disengaged to change gear, and the alternator is electrically connected when the vehicle is being driven in cut-off mode.

A boost charging control method, apparatus, and a storage medium, wherein the boost charging control method includes selecting, based on an electrical angle of the motor, two phase windings of a motor with top two inductance strengths as working windings. The method also includes controlling currents of the two phase windings, and setting a current of the other phase winding as zero, thereby causing the motor to generate a set torque. A boost charging control method, apparatus, and a storage medium are disclosed, which may cause a motor to generate a set torque, and reduce shaking and noise due to motor torque fluctuations.

Modestly modified automotive engine powered generator systems to substantially improve capability for providing renewable electricity powered grid reliability and energy storage are disclosed. The use of these engines to improve capability for non-grid electricity generation, including affordable and clean fast charging of electric vehicles, is also disclosed. In one embodiment, these automotive high RPM and engines use stoichiometric air fuel ratio operation so as to provide the advantages of substantially reduced cost and NOx emissions. These engines also have multifuel capability that provides highly flexible use of low carbon fuels (such as hydrogen, methanol and ammonia) as well as the use of present fuels that are widely available. When these low-carbon fuels are produced with excess electricity from the grid and supplied to the grid when there is an electricity-supply shortfalls, they can serve as a means of energy storage.

A computer system can remotely manage a vehicle's operational settings. The computer system can cause operational settings data to be downloaded to a vehicle to control one or more operations of the vehicle. The computer system can generate download event information indicating the operational settings data downloaded to the vehicle and a user associated with the vehicle. The computer system can access a pricing structure associated with operational settings. The computer system can charge the user based on the pricing structure and the download event information.
