Electric buses with wireless charging have proven to be 51% cheaper than diesel
With three solid years of regular daily operation, Link Transit’s electric buses are proving their worth, according to Richard DeRock, general manager of the Wenatchee, Wash., transit agency. Now with 12 electric buses in service, all using wireless chargers installed by Momentum Dynamics, the global leader in efficient and automated high-power wireless charging for electric vehicles, Link operates one of the largest fleets of electric buses in all public transport systems in the country. DeRock reports that the cost of operating their electric buses is about 51% of a diesel bus.
Momentum Dynamics installed the first wireless load system on Link at the end of 2017 and more recently installation of four inductive chargers of 300 kW in 2021, three at Columbia Station and one in Leavenworth, WA. These four shared chargers support all of Link’s electric buses and keep them in constant service throughout the day.
“Momentum’s wireless chargers were a game changer for us,” DeRock said. “They charge our electric buses for a few minutes when stopping between routes and provide extra range, allowing our buses to stay in service for 12 to 14 hours a day – even in the harsh cold of winter. buses typically end their day with 40-50% battery charge, even on the coldest days.The cost savings are real and measurable.In addition to the availability of low-cost, renewable hydropower from the Columbia River and lower maintenance costs, it makes expanding our battery electric bus fleet a financially sensible solution to combating climate change.”
To replace the aging diesel buses and allow the expansion of the service, Link will take delivery of three other buses of 35 ′ at the beginning of 2023 and eight other buses of 30 ′ later in 2023, which will use all the wireless Momentum chargers To extend the scope and allow operational efficiency. .
“We are very pleased to support Link Transit in its journey towards a healthier future in a cost-effective way,” said Andy Daga, CEO of Momentum Dynamics. “Wireless charging makes fleet management very efficient as the system provides increased range and eliminates the need for a depot full of cables and chargers, all of which are subject to wear and create a hazardous condition for workers. It is the most reliable and cost-effective charging system for fleets available today.”
Other communities are now using wireless chargers for their transit buses installed by Momentum Dynamics, including Indianapolis, Martha’s Vineyard, Chattanooga, TN, and new installations in Washington, Oregon, California and other states. The new terminal at Kansas City International Airport has been equipped with the wireless chargers to support their buses which will transport passengers between the terminal and the parking lots with an initial fleet of 7 (eventually 28) buses which will be kept in operation Constant using only two shared wireless chargers.
Momentum Dynamics, located in Malvern, Pennsylvania, is the world leader in the high power inductive load for all types of electric vehicles, including passenger vehicles, buses, delivery trucks and heavy goods vehicles. The company practices world-class technological innovation through modular design and is recognized for the extraordinary achievements and unique expertise of its engineers and scientists. Momentum won the 2019 Emerging Technology Award from Mechanical Engineering magazine.
