The invention discloses an electronic device and a charging control device and a method thereof. The device comprises a battery protection plate which comprises a first connection end, a second connection end, and a charging and discharging circuit arranged at the first connection end and the second connection end, wherein the first connection end is connected with a battery cell of the electronicdevice; A charge / discharge circuit connected to the second connection terminal and connected to the battery cell through the charge / discharge line and the first connection terminal on the battery protection plate; a voltage detection terminal; a cell connection circuit, wherein a first end of the cell connection circuit is connected with the cell, and a second end of the cell connection circuit is connected with a voltage detection end; a control unit, A control unit is connected to the voltage detection terminal, The control unit detects the voltage of the cell through the cell connection circuit to obtain the cell voltage detection value, and controls the charging process of the charging and discharging circuit according to the cell voltage detection value, so as to ensure accurate control of the charging process, shorten the charging time in the constant voltage stage, and reduce the filling time of the cell.
Description
technical field [0001] The present application relates to the technical field of charging, and in particular to an electronic device and a charging control device and method thereof. Background technique [0002] The charging solution in the related art usually controls the charging process by detecting the voltage at both ends of the Pack of the battery protection board. However, the voltage of the actual battery cell will be lower than the voltage across the Pack of the battery protection board, thus resulting in inaccurate control of the charging process and longer charging time. Contents of the invention [0003] The present application provides an electronic device and its charging control device and method, so as to shorten the charging time in the constant voltage stage and reduce the charging time of the battery cell. [0004] The embodiment of the first aspect of the present application proposes a charging control device for electronic equipment, including: a bat...
