Provided is a power management apparatus for controlling power distribution from a location that includes a storage battery and a current control type converter to another location that includes a storage battery, the power management apparatus including: a monitor unit that acquires a status of the storage battery at each location; a judgment unit that determines, based on the status of the storage battery at each location that has been acquired by the monitor unit, a duration of power distribution to a certain location, and one or more locations from which power is to be distributed to the certain location; and a control unit that controls each location serving as a distribution source such that power distribution is performed for the duration determined by the judgment unit.

A disclosed battery management system for wireless charging includes a communication circuit and a controller. The communication circuit receives information on a first state of charge (SOC) of the first battery module, a second SOC of the second battery module, and a third SOC of the third battery module. The controller controls the first wireless charging between the first battery module and the second battery module and the second wireless charging between the second battery module and the third battery module for balancing between the first SOC, the second SOC, and the third SOC. The first wireless charging is to wirelessly transmit power from one of the first battery module and the second battery module to the other battery module. The second wireless charging is to wirelessly transmit power from one of the second battery module and the third battery module to the other battery module.

A battery charging cable can be connected to a power supplying device and supply electricity to, and thereby charge, the battery of another device when the battery is low in power. The battery charging cable includes a USB Type-C connector at one end and a positive-electrode clamp and a negative-electrode clamp at the other end, wherein the clamps can be respectively clamped to the positive and negative electrodes of the battery of a device to be charged. With the battery charging cable supporting a USB Power Delivery protocol, and the USB Type-C connector configured to provide a relatively high voltage and power, the battery charging cable provides overload protection and has great power transmission performance.

A sheath with a raised portion with a second open end, a bottom portion, a power storage space in a body, a magnet component configured to receive a mobile phone wireless charging holder, a USB cable having a female connector with an operative end, at least a portion of the bottom portion is in communication with the body, at least a portion of the sheath extends above the body, the operative end of the female connector is retained in the second open end to provide the female connector of the USB cable in a firm and flat position with the operative end of the female connector being operable and above the surface of the body, an exit on the body is adjacent to the sheath for the cable going through, which connects the female connector in the sheath to the power storage space and the wireless charger connects to the operative end.

The present disclosure provides a mobile power supply and a method for supplying power to a peripheral device. The mobile power supply comprises a first peripheral connection port and a second peripheral connection port, a first group of connection-port processing circuits and a second group of connection-port processing circuits, a control circuit, and a power supply circuit. A control strategy determining circuit in each group of connection-port processing circuits determines a voltage adjustment strategy according to power supply status information of a corresponding peripheral connection port. The control circuit then causes a voltage adjusting circuit in the connection-port processing circuit to adjust, according to the voltage adjustment strategy, a voltage output by the power supply circuit, such that the adjusted voltage is used to supply power to a peripheral device coupled, by means of a power supply terminal, to the peripheral connection port.

A charging system for charging a vaporizer device is described. The charger may be adapted to control the output voltage to the vaporizer device, thus improving charging efficiency and reducing waste heat generation. Related systems, methods, and articles of manufacture are also described.

A battery in a mobile phone cover may be selectively charged according to a user-selectable parameter. When charged, the battery in the mobile phone cover may be used to charge a battery in a mobile phone.
