A detection circuit and method for charging start. The detection circuit for charging start comprises a cell connector, a first controller, a second controller and a switch circuit. The first controller sends to the second controller in real time an anode contact signal, a cathode contact signal and an electric quantity signal that are received from the cell connector; upon receiving a charging request signal, the second controller sends a start command to the first controller if good contact with an anode of the cell is confirmed according to the anode contact signal, good contact with a cathode of the cell is confirmed according to the cathode contact signal, and it is confirmed according to the electric quantity signal that the voltage of the cell does not exceed a voltage threshold; afterwards, the first controller sends a connect command to the switch circuit to control connection of a charging end and a cell end of the switch circuit; and then a charging adapter charges the cell through the switch circuit. |
