Conductive Charging

Conductive charging is a way of transferring electrical power through direct physical contact between a charging device and its power source, rather than across a gap. Infrastructure such as an overhead board or a rail delivers power to a matching receiver or pickup on the device being charged, and the system energizes the contact once it recognizes a valid receiver, so the defining feature of conductive charging, unlike inductive or other wireless charging methods, is a true conductor to conductor connection between the two. It is used both for small portable electronics, such as phones sitting in a charging cradle, and, increasingly, for electric vehicles, where ground level conductive rail or contact systems developed by companies including Honda, Elways and ABB can deliver hundreds of kilowatts to buses and trucks even while they are moving.
