Momentum Dynamics to supply Link Transit with wireless chargers for 10 battery-electric buses
Momentum Dynamics will supply 10 of its 300-kw wireless charging systems for Link Transit’s 10 new battery-electric BYD K9S buses.
All new buses added to the Link Transit fleet are fitted with wireless charging receivers from Momentum Dynamics.
In February 2018, Link Transit commissioned 200-kilowatt wireless charging system from Momentum Dynamics for a battery-electric transit bus. The system has been operational on a BYD K9S bus since then. Following the successful introduction and operation of a wirelessly charged bus in 2018, Momentum Dynamics and Link Transit extended their relationship with a new five-year agreement in January 2020. As part of the agreement, Momentum Dynamics will provide three new on-route charging stations, each capable of delivering 300 kw. These stations are used to support the bus fleet.
Because of its modular design, the system is efficient in terms of both energy utilization and the number of chargers required, according to the company. Each module, or pad, is rated at 75kW. By specifying multiple pads, vehicles can be rated up to 300-450 kW per bus.
The same system can be used with passenger cars, taxis, buses and delivery vehicles. Its design makes the system suitable for both on-route charging and in-depot use. The system is installed below ground or on the pavement inside garages, depending on the use case. Charging happens automatically without human intervention. Partial battery charging is a means of providing vehicle energy because it can keep a vehicle charged and in-service indefinitely while substantially extending the useful life of the battery, says Momentum Dynamics.
