Multi-coil inductive power transmission technology has been widely investigated due to their ability to charge devices in large transmission area. In this paper, an implementation of multi-coil inductive power transmission system has been presented. The proposed system is composed by 16 coils organized in 4 columns and 4 rows controlled by switches. A small size sending side circuit is used, which is composed of a singular AC oscillator, power amplifier, resonant compensation capacitor and a passive voltage. This circuit offers a small size electronic parts, simplicity during implementation and low cost. An IoT Android application offers to the user the possibility of tracking the device to be charged on top of multicoil sending inductive power transmission system. A Bluetooth module has been connected to the sending side circuit to establish the communication with the user smartphone. To show the electronic circuit voltages, an LTspice simulation using realistic components has been presented. The proposed multi-coil system with the developed Android App. has been experimentally implemented.
