Several forms of wireless power transfer exist today. The most common is inductive charging – as typically found in consumer devices such as cell phones and electric toothbrushes. Unfortunately, inductive systems are only efficient when the antennas are extremely close – but robots and Unmanned Aerial Vehicles (UAVs) can’t position themselves accurately enough to ensure inductive systems will provide a reliable and efficient charge. Magnetic resonance is a newer technology that offers more flexibility in positioning. Typical resonant systems have a “sweet spot” where efficiency is maximized. As long as the robot can navigate to that exact spot every time, maximum efficiency can be achieved. If the robot stops short or is off-center, efficiency is reduced, and charge times increase.WiBotic’s high power systems have an end-to-end efficiency level between 75% and 85%. This represents the full system efficiency from power input to our transmitter circuit to Onboard Charger’s outp...
