Momentum Dynamics, a Malvern-based company that develops high-power inductive charging technologies for the automotive and transportation industries, has commissioned the nation’s first 200-kilowatt wireless charging system for a battery-electric transit bus fleet.
The first-of-its-kind wireless charging system is now operational on a BYD K9S bus at Link Transit in Wenatchee, Wash., representing the future of electric mass transit.
The Momentum 200 kW Wireless Charging System is embedded in the pavement at Link Transit’s Columbia Station in Wenatchee.

“Across the globe, transit agencies are transitioning to electric buses as quickly as they can but driving range limitations are impeding faster adoption,” said Momentum’s CEO Andrew Daga. “These agencies have been waiting for a solution that will guarantee their new electric buses can drive any route while maintaining an adequate energy reserve under all conditions.”
For electric transit, wireless charging is the most effective method for on-route opportunity charging. Within five minutes, the wireless charging system automatically adds enough energy to the vehicle’s battery to complete another route during its routine transfer station stop. This allows the electric bus to drive unlimited route cycles. Buses with Momentum’s wireless charging system stop over the charging transmitter embedded in the road to charge automatically.
“This state-of-the-art technology is a game changer for battery electric fleets across the nation,” said Todd Daniel, Technology Manager for Link Transit. “The simplicity, along with seamless charging, allows Link Transit to operate all of our urban service routes continuously without the need for midday charging.”
