Abstract
The invention discloses a CP signal isolation driving AC charging pile comprising a central controller, an AC/DC converter, a counter, a charging module, a CP memory module, and a detection device. The central controller is in communication connection with the AC/DC converter, the counter, and the CP memory module. The CP memory module is in communication connection with the charging module and the detection device. A coupled driving circuit in the detection device sends a driving signal to a differential amplification circuit to be amplified. A filter network circuit enables stable signal output. A phase detection circuit detects an intersection angle between current and voltage. A charging and discharging current sampling circuit detects the current value of a signal. A battery voltage sampling circuit detects the voltage value of the signal. The current value and the voltage value are transmitted to the central controller via the CP memory module in order to compute the internal resistance of a battery, determine the electric energy of the battery, and calculate a charging time length. When an apparatus is charged, the AC/DC converter, the counter, and the charging module operate.
