Abstract: Provided are a battery pack, a cell module and a cell module assembly. Herein, the battery pack includes at least one cell module, and a communication connector connected with the at least one cell module to wiredly communicate with external equipment, in which the at least one cell module is connected with the communication connector to control charge and discharge of the cell according to a control command received from the external equipment, and the external equipment is installed with an external hardware device in which a battery management system transmitting the control command is implemented or software implementing the battery management system.

Abstract: An exemplary embodiment of the present invention provides a power device driving module. The power device driving module includes a module-processor configured to receive driving information from a central controller to generate a driving signal based on the driving information, and a driving circuit connected to a power device to switch the power device depending on the driving signal.

Abstract: A battery power supply device is provided. The battery power supply device includes: an input unit that receives external power; a battery power unit that is connected to the input unit to charge a battery with the external power; a current detection unit that detects a current that is supplied to a load and that provides the current to the battery power unit; and an output unit that provides the external power and battery power from one node to the load and that receives a load current from the battery power unit to adjust output of the battery power.

Abstract: The present invention relates to a golf navigation terminal and a golf navigation device using the same. One of the things people always care about when playing golf is scorekeeping. The present invention automatically calculates a score so that a golf player can concentrate on his or her play. When the golf player plays a game, while wearing the golf navigation terminal of the present invention on the waist, the golf navigation terminal automatically detects how the player is doing and sends this to the golf navigation device, and the golf navigation device then calculates the player's score. Afterwards, the score is wirelessly communicated to the golf navigation terminal. The score is fixed after the player's confirmation or correction. According to the present invention, the player may view his or her score from time to time, either through a display on the golf navigation terminal or on the golf navigation device.

Abstract: The present invention discloses a battery pack which can be used for an electric vehicle, an Uninterrupted Power Supply (UPS), and a power supply for a smart grid and which can be easily manufactured and repaired and which is capable of improving productivity, the span of life, and performance, and a battery management system including the battery pack.
