Title: BATTERY PROTECTING BOARD, BATTERY, AND MOBILE TERMINAL
Abstract:
A battery protecting board, a battery, and a mobile terminal. The battery protecting board (10) comprises: a lead (17), the lead is connected in series in a charging/discharging circuit (13), the lead is arranged at a first windowed area of the battery protecting board; a battery level gauge (15), the battery level gauge is connected to either extremity of the lead, during the process in which the battery is being charged or discharged via the charging/discharging circuit, the battery level gauge detects a voltage drop produced by the impedance of the lead and determines the power level of the battery on the basis of the voltage drop; a thermal pad, one extremity of the thermal pad is connected to the first windowed area via an insulating thermally-conductive material, the other extremity of the thermal pad is connected to a second windowed area of the battery protecting board, the thermal pad transfers heat from the first windowed area to the second windowed area, thus not only reducing the number of components in the battery protecting board, saving the area for board layout and costs for the battery protecting board, but also reducing the temperature of the battery protecting board.
