The present invention detects a predictive abnormal phenomenon in a battery pack and prevents the use of the battery pack before power is shut off at a fuse. The battery pack comprises: a battery cell; a connection unit which is electrically connected to the battery cell and is connected to an external electrical apparatus main body; and a control unit which controls the battery cell, wherein, when detecting an abnormal state such as chattering, the control unit causes a charge prevention signal (LS) and a discharge prevention signal (LD) to be continuously output and makes the charge and discharge of the battery pack impossible (steps 226-228). The continuous output of these prevention signals is configured not to be negated by an operation of a user, and the battery pack can be made unusable by software control.

A battery pack charger including a housing, a charging circuit, a first charger terminal and a second charger terminal connected to the charging circuit and configured for providing charging power to a battery pack, and a controller. The controller includes a processor and a memory. The controller is configured to charge the battery pack with a constant power charge, switch to a constant voltage charge when a voltage of the battery pack reaches a predetermined threshold, and charge the battery pack with the constant voltage charge.

A wireless speaker and camera assembly includes a remote control for storing data comprising a remote control program. A housing is included and a speaker is integrated into the housing to emit audible sound outwardly therefrom. A camera is integrated into the housing to capture images of the environment in which the housing is positioned. A transceiver is integrated into the housing and the transceiver is in communication with the speaker and the camera. Additionally, the transceiver is in remote communication with the remote control to send and receive audio data and image data with respect to the remote control thereby facilitating the speaker to stream audio received from the remote control.

A charging and storage system provides a conveyor system within a housing that conveys electronic devices through the housing to charging devices located withing the housing. Charging contacts on an adjustment arm adjust between a charging position that charges the electronic devices and a transport position that allows movement of the electronic devices through the housing without contacting the charging contacts. A charging device located at each charging location charges the device while the device is stored within the housing. The conveyor system moves the electronic devices to these fixed charging locations to charge the devices while storing the devices. The conveyor system releases the electronic devices to an exit ramp that guides the electronic devices to a release aperture for removal from the housing.

A power storage system of the present technology includes a battery board configured to accommodate a secondary battery, a branch board, a first frame on which the battery board is placed, a second frame on which the branch board is placed, and a plurality of connection wirings that are disposed in the first frame and the second frame and connects the battery board and the branch board. The plurality of connection wirings are aggregated in the second frame.

An apparatus comprises a power electronic energy conversion system comprising a first energy storage device configured to store DC energy and a first voltage converter configured to convert a second voltage from a remote power supply into a first charging voltage configured to charge the first energy storage device. The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.

A sensor system for detecting a property of or within an absorbent article may comprise an absorbent article and a sensor. The absorbent article may comprise a garment-facing layer and an absorbent assembly. The sensor may be disposed in and/or on the absorbent article. The sensor may be separable from the absorbent article. The sensor may be configured to sense a change in condition within the absorbent article.

A charger cradle for recharging a rechargeable lighting device is described. The cradle may include two prongs that flex outwards to allow a lighting device to be inserted into the cradle. After the lighting device is fully inserted, the prongs resume a normal position to exert an inward force on the lighting device to secure it in place. The cradle may also include two moveable cradle arms, in lieu of two prongs, to allow a spring mechanism within the device to motivate the moveable cradle arms to grasp a lighting device when the lighting device is inserted into the rechargeable lighting device.

The invention relates to a device and a method for automatically charging an electrical energy storage means in a vehicle. For this purpose, firstly, the position of a charging socket on a vehicle is determined, based on vehicle-specific data. Subsequently, a charging robot travels on the ground near to the charging socket. Then, the charging robot establishes a galvanic connection between the charging station and charging socket. For this purpose, the charging robot introduces a contact head connected to the charging station into the charging socket of the vehicle. After termination of the charging process, the contact head is removed from the charging socket, thereby releasing the vehicle.

A battery and an electronic device are provided. The battery includes a battery cell, including at least one anode of the battery cell and at least one cathode of the battery cell. The battery also includes a voltage detection circuit, wherein the voltage detection circuit detects a voltage of the battery cell. Further, the battery includes a protection circuit, wherein the protection circuit protects the battery cell based on the voltage of the battery cell detected by the voltage detection circuit.
