Systems and methods are disclosed herein for a charging system. The charging system may be implemented within an independent charging station or within an autonomous vehicle. Boolean charging can be used to obtain the desired charge or discharge voltage for charging an autonomous vehicle at a charging station. By combining a subset of a sequence of batteries arrays that differ in voltage by powers of two in series, where each battery array may include multiple batteries or battery cells, a voltage may be obtained which is equal to the sum of the voltages across each battery array. This voltage may be used in turn to charge additional batteries or battery arrays. The process may be repeated until the desired amount of battery arrays has been charged and the desired voltage has been achieved.

The present disclosure discloses a charging apparatus. The charging apparatus comprises a power source module, a main control circuit, a voltage booster circuit, an adjusting circuit, and an output port. The charging apparatus is configured to charge a vehicle battery or other consumers through the output port. The power source module is electrically connected to the main control circuit and the voltage booster circuit. The main control circuit is electrically connected to the adjusting circuit and the voltage booster circuit. The main control circuit is configured to output an adjusting signal to the adjusting circuit. The adjusting circuit controls the voltage booster circuit to output a first or second output voltage to the output port, according to the adjusting signal. The second output voltage is greater than the first output voltage. The present disclosure provides a plurality of voltages to meet the vehicle battery.

A switching unit is included, which is arranged between a first electric storage unit of a first electric storage device configured to be connectable in parallel with a second electric storage device and a wire electrically connecting the first electric storage device and the second electric storage device, and which is configured to switch a electrical connection relationship of the wire and the first electric storage unit. A restricting unit is included, which is connected in parallel with the switching unit between the wire and the first electric storage unit, has a higher resistance than the switching unit, and is configured to cause a current to flow in the direction from the wire to the first electric storage unit and suppress current flowing in the direction from the first electric storage unit to the wire.

A vehicle battery charging apparatus for wirelessly charging a device. The apparatus has a charging device compartment with a platform for retaining the device, and a battery charger housing for retaining a wireless battery charger. One or more housing vents are provided in the battery charger housing. And, a blower is in air communication with the battery charger housing to communicate air with the battery charger housing through the one or more housing vents to cool the wireless battery charger.

A calibration device for a charging device of an electric vehicle and a method for calibrating a charging device of an electric vehicle are described.

An energy storage assembly includes a vertical stack of substantially planar modules. Each module comprises a plurality of energy storage components and a thermally conductive shell comprising a shell top, a shell bottom, shell sides, a shell front, and a shell rear.

An inductive charging system for inductive charging of electronic devices is disclosed. In accordance with an embodiment, the system includes a substantially planar inductive charging coil parallel to the surface of the inductive charger or the electronic device. The system further includes a metallic layer positioned proximate to and substantially parallel to the inductive coil to cover a surface of the inductive coil. The metallic layer comprises multiple substantially concentric rings or polygons, with each of the concentric rings or polygons having multiple sections separated by gaps such that each concentric ring or polygon is discontinuous. Adjacent sections of each concentric ring or polygon are electrically isolated from one another to avoid eddy current generation and heating of the metallic layer during inductive power transfer.

Exemplary portable electronic devices include a housing and a power connector interface. The housing has a power input opening and includes a controller, a rechargeable battery, and battery charging circuitry coupled to the rechargeable battery. The power input opening is sized to receive an electrical connector of a cable assembly.

At least one of the other conductors is configured to receive a signal, and the controller is responsive to the signal and is configured to control the battery charging circuitry.

A wireless charging module includes a housing configured to support at least one coil module therein. The housing includes an upper housing portion and a lower housing portion. The upper housing portion includes at least one vent. The lower housing portion includes at least one vent. One or more ducts are provided within the housing. The one or more ducts are in communication with the at least one vent of the upper housing portion and the at least one vent of the lower housing portion. An airflow path is defined from the at least one vent of the upper housing portion through the one or more ducts to the at least one vent of the lower housing portion for allowing an air flow internally within the housing generally around and/or adjacent at least a portion of the at least one coil module supported within the housing.

Provided is an electric battery charging system, including a connector including a thermistor element configured to change a resistance value according to a temperature, a micro control unit (MCU) configured to receive a voltage varying depending on whether the connector is connected, and receive a voltage varying according to the resistance value of the thermistor element, and a vehicle charging management system (VCMS) configured to determine whether to discharge a battery based on whether the connector is connected and a temperature of the connector.
