Abstract
A detection circuit and a detection method for starting charging are provided. The detection circuit comprises a cell connector, a first controller, a second controller and a switch circuit. The first controller sends an anode contact signal, a cathode contact signal and an electric quantity signal received from the cell connector to the second controller; the second controller sends a start instruction to the first controller if a charging request signal is received, the anode of the cell is well contacted, the cathode of the cell is well contacted, and a voltage of the cell does not exceed a voltage threshold; the first controller sends a connection instruction to the switch circuit to control connection of a charging terminal and a cell terminal of the switch circuit, such that a charging adapter charges the cell through the switch circuit.
