A system for transferring electrical energy from a charging station to an electrical consumer including a charging plug connected to the charging station by a charging cable and a charging socket corresponding to the charging plug of the electrical consumer designed as a motor vehicle, wherein the motor vehicle is designed to receive a battery voltage at the charging socket and relay it, unchanged, to a vehicle battery, wherein the charging station is configured to receive a network voltage from a power grid and to relay it via a charging cable to the charging plug, and the charging plug is configured to convert the network voltage into the battery voltage by means of power electronics.

An off grid electric vehicle charging system that includes an off grid power supply system and an electric vehicle charging plug adapted to connect with any electric vehicle and provide electric power thereto. The off grid power supply system incorporates rechargeable battery members adapted to provide uninterruptible off grid electrical power and are charged and recharged by solar panels and/or wind turbines and/or a water wheel. Furthermore, when the solar panels and/or wind turbines and/or a water wheel are insufficient to recharge the battery members a motorized engine is automatically started to recharge the battery members until the solar panels and/or wind turbines and/or a water wheel are sufficiently operable to recharge the battery members once again. The electric vehicle charging plug is adapted to connect with any electric vehicle and provide DC electric power thereto. The system further includes an alternator for converting the electricity from the battery members into DC electrical current, automatic on/off switches, and a control panel.

A device according to one embodiment includes a first battery to output alternating-current power for driving a motor and connected to a first main circuit that is connected to an inverter; a second battery connected to a second main circuit, having a storage capacity larger than it of the first battery, and having a permissible power output per unit storage capacity smaller than it of the first battery; a DC/DC converter to convert a voltage of the second main circuit to a predetermined voltage and output to the first main circuit; a control circuit to control charging and discharging operations of the first and the second battery and an operation of the DC/DC converter; a first terminal connected to a positive terminal of the first battery; and a second terminal connected to a negative terminal of the first battery.

An electric propulsion system includes a rotary electric machine having an output member, a rechargeable energy storage system (“RESS”) connected to the electric machine, a user interface device, and a controller. The RESS includes multiple battery modules and a switching circuit, the latter being configured, in response to electronic switching control signals, to connect the battery modules in a parallel-connected (“P-connected”) configuration or a series-connected (“S-connected”) configuration, as a selected battery configuration. The user interface device receives an operator-requested drive mode signal indicative of a desired drive mode of the electric propulsion system. The controller, which is programmed with mode-specific electrical losses associated with the desired drive mode, establishes the selected battery configuration in response to the drive mode signal, and presents a drive mode recommendation via the user interface device when the losses associated with the desired drive mode exceed a calibrated loss threshold.

A portable power source includes a housing and a battery receptacle supported by the housing. The battery receptacle is configured to receive a battery. The portable power source also includes a first power tool battery pack port that is configured to receive a first power tool battery pack. The portable power source further includes a charging circuit coupled to the battery receptacle and the power tool battery pack, and an inverter. The charging circuit is configured to receive power from the battery receptacle and to provide power to the power tool battery pack port. The inverter includes a DC input coupled to the battery receptacle, inverter circuitry, and an AC output. The inverter circuitry is configured to receive power from the battery receptacle via the DC input, invert DC power received from the battery receptacle to AC power, and provide the AC power to the AC output.

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 engines use high RPM and 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 control system includes a management unit configured to control a power supply device toward a target value for an output performance value of the power supply device that supplies power to a predetermined device, and an acquisition unit configured to acquire information related to a post-shutdown task scheduled to be executed after a shutdown condition of the predetermined device is satisfied, in which the management unit refers to the information acquired by the acquisition unit, and, when the post-shutdown task is scheduled to be executed, sets the target value to a second target value which is higher than a first target value set when the post-shutdown task is scheduled to be executed, before the shutdown condition is satisfied.

The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.
