Today Momentum Dynamics announced this year it will deliver 200-kilowatt inductive wireless chargers for municipal bus fleets in Maryland and Washington state.
Presently the highest power electric passenger vehicle chargers are Tesla’s 135-kW Superchargers.
Momentum has announced no plans to deliver such high power systems as it is set to do for bus agencies for “on route” charging, but has said it is technically feasible.
The company has worked behind the scenes with numerous concerns including international parcel delivery services with household names, and automakers who also wish to remain anonymous.
Last year the company delivered 25 kW and 50 kW charging systems to un-named partners in the automotive industry.
The 200-kW bus systems will be delivered this year, said CEO Andy Daga.
Momentum says the move to 200 kW system “is a natural progression to meet a critical market need. Even higher power systems are in development.”
“These high power levels are causing a lot of excitement across targeted vertical markets,” said Daga, “especially with municipal bus transit agencies where high power is required to keep a municipal bus in operation all day.”
The company based in suburban Philadelphia says its system using a transmitter on the ground and power receiver on the underside of the vehicle with 12-inch air gap has “the efficiency of inductive charging is equivalent to plug-in charging.”
Advantages for the transmitter which may be embedded in concrete include operation in all weather, including through ice and snow. It also resists vandals and stands to escape other deterioration caused by exposure to the elements.
It also may be more convenient and has applications including opportunity charging at curbside for waiting taxis, and the like, as well as simple operation for regular consumers in their driveway or garage.
The company says the automatic operation makes wireless inductive charging “a background operation” and has projected the industry is working toward greater acceptance of the technology.
“Fast automatic charging will enable the EV market to grow faster,” said Daga. “It is completely autonomous, carefree and safe.”
