A device management system, method and apparatus are disclosed. The device management method comprises: sending, in response to a borrow and return request, an unlocking instruction to an electromagnetic lock configured for a device management cabinet, wherein the electromagnetic lock unlocks the device management cabinet in response to the unlocking instruction; receiving charging state information of a target device storage unit that is returned by the device management cabinet, wherein said device is stored in the target device storage unit; receiving lock state data of the device management cabinet that is sent by the electromagnetic lock, and acquiring electric quantity state information of said device; and generating, according to the charging state information, the electric quantity state information and the lock state data, borrow and return information of said device.

In a power storage pack, a power storage unit supplies electric power to an electric mobile body. A wireless communication unit performs short-range wireless communication. A notification unit presents, to a user of a mobile terminal device, a tentative notification of a verification code that is to be used in the process of exchanging an encryption key that is to be used for the short-range wireless communication with the mobile terminal device. The notification unit may include a remaining capacity display for the power storage unit.

Various embodiments include systems and methods for balancing battery cycles of paired earbuds. A processor in an earbud charging case may receive battery level information from a first earbud operating in a deep sleep mode, determine a battery differential index (BDI) value, and send an instruction message to the first earbud indicating the first earbud should switch roles with a second earbud. An earbud may start a timer upon beginning to operate in a dormant mode, transition from operating in the dormant mode to operating in a non-dormant mode in response to expiration of the timer, send a message to a paired earbud indicating that the earbud has transitioned, and receive a message from the paired earbud indicating that the earbud should switch from operating in the dormant mode to operating in the deep sleep mode and periodically broadcasting an advertisement.

A charge system for wireless temperature probe includes a probe body and a charging relay box detachably connected with the probe body, the probe body is provided with a first wireless charging component and a sealing structure. The charging relay box is internally provided with a power supply module, a control module and a second wireless charging component configured to establish a near field communication path with the first wireless charging component, and the control module is used to control the power supply module to adaptively supply power to the probe body through the near field communication path.

An intelligent rechargeable battery pack having a battery management system for monitoring and controlling the charging and discharging of the battery pack is described. The battery management system includes a memory for storing data related to the operation of the battery, and the battery management system is also configured to communicate the data related to the operation of the battery to other processors for analysis.

A method is provided comprising: detecting a connection between an electronic device and a battery charger; transmitting to the battery charger a first request for at least one of a first voltage level and a first current level; receiving from the battery charger a signal; and charging a battery of the electronic device with the signal.

One or more features of an electronic cigarette or an electronic cigarette charging case is configured to hold the electronic cigarette in place and inhibit it from rolling and charge the electronic cigarette.

An example operation includes one or more of wirelessly notifying, via a charging station, at least one transport of a group of identified transports of a needed amount of energy stored in the at least one transport prior to the at least one transport being connected to the charging station.

A charging system is disclosed. The charging system includes multiple charging circuits to simultaneously charge chargeable devices in proximity of the charging system. The charging circuits establish wireless communications associated with charging of the chargeable devices. Due to simultaneous wireless communications, a cross-talk interference leads to an error in at least one of the wireless communications. Upon detecting the error, the corresponding charging circuit generates a delay value. After a time delay that is based on the delay value, the charging circuit reestablishes the wireless communication with the chargeable device thereby mitigating the crosstalk interference. The charging circuit charges the chargeable device upon successful reestablishment of the wireless communication.
