Lipo Wireless Charger

Hi Everyone,

I'm trying to make my own version of a robotic vacuum with a wireless charging station. I want my robot to be able to drive up to the charging station and then recharge itself. However, my first issue is trying to make a lipo battery charge wirelessly. I've seen wireless charging kits online for mobile phones but I'm not sure if they would even work for a lipo. My lipo is an 11.1v 2.2amp battery. As part of my design, I want my robot to self manage its battery level using a voltage divider. That way the robot will be able to return to the charging station and recharge when needed.

Does anyone know of a way that I can make a lipo charge wirelessly?
