Abstract：This paper describes the single-coil current sensing device installed in higher voltage lines for trickle charging, and presents the method of single-coil current sensing device for trickle charging. The device can achieve the function of obtaining electricity and monitoring the current for using only one current transformer. This device has many obvious advantages in weight and volume, and it is small and easy to install. In addition, the device with the super capacitor can store electrical energy from higher voltage lines, and this super capacitor discharges to provide electrical energy for the device. At the same time, there are some protection circuits around the super capacitor, so the device could monitor the wide range of current.
