 Hello everybody, this is Gianni Vitale from ST Microelectronics. In this short video today we want to present a demo where we will be using the wireless charging technology to charge the batteries for power tools. This is possible thanks to the new products developed by ST, the STWBC2 on the TX side and the STWSE88 on the RX side, because the combination of the two products is capable of reaching power up to 15W and delivering a voltage output of 20V. In this demo we also have power tools which is driven by an ST-SPIN32F0, which is an advanced BLDC controller with embedded STM32MCU. So, after the demonstration of the charging of the battery through the wireless charging technology, we use the battery to supply the power tools and we will also see the tools driven by ST-SPIN32. Let's start the demonstration now. We put the receiver coil on top of the transmitted coil, in this way the power transfer starts and the receiver board is now supplied and connected to the PC. We need to implement a sequence to raise the voltage from the 5V default to 18.5V needed to charge the battery. This part in a real application is managed by an MCU communicating with the STWSE88. Here we are using the GUI to show the transition and the voltage in the output reached 18.5V. Once this is done, we can now connect the battery and the battery starts charging. The charging is visible by looking at the current on the screen on the GUI, which is reported by the STWSE88 and we can see that the current is start rising through the negotiation between the RX and the ATX side step by step increasing the current. The current will reach in this demonstration 1A because the battery is fully charged but the device is capable of reaching up to 2.5A and deliver 15W. Let us now disconnect the battery from the RX side in order to plug the battery into the power tools. As a reminder, this is driven still by a product from STWSE88, which is the SSP32F0. By plugging the wires now, we can turn on the power tools and you can hear that the motor of the power tools is spinning. To conclude, thank you very much for listening this short video and the demo regarding where is power transfer applied to power tools.
