Primove, a subsidiary of transportation giant Bombardier, just announced plans to test wireless induction charging on public buses in Manheim, Germany! In a few months the company will outfit two buses with “invisible” inductive technology that powers the vehicles with wireless chargers installed below the asphalt of existing bus routes.
Induction works by creating a magnetic field using conductors. Primove uses rods of varying lengths buried underneath the asphalt to act as those conductors. The magnetic field then generates electricity when another conductor, in this case a vehicle, comes in contact with the field. The electricity that’s generated is then picked up by the undercarriage of the vehicle and routed to its battery.
Charging can happen when the vehicle is stopped or even just moving over the induction surface. When there is no vehicle within its field, the charger is inactive. And according to Primove, its induction rods won’t interfere with cell phones or pacemakers. The best part about this wireless technology is that it isn’t susceptible to water or the weather.
A key benefit to Primove’s inductive charging system is that it allows for continuous electric bus operation due to high-power charging locations embedded within existing bus routes. Another benefit is that by extending battery life with intermediary inductive charging, electric vehicle batteries can get smaller and make more room for passengers. Plus, induction charging lowers the cost of ownership of an electric vehicle as you can charge your battery for free by just driving on the streets with embedded chargers.
