California still leads in electric school bus adoption, with over 2,000 committed electric buses across the state, at least 34% of which are delivered or operating.
With over 200,000 electric buses, China is the undisputed ruler of the electric bus market. With over 16,000, Shenzhen leads cities across the world. The rest of us are simply playing for second place.
Featuring two electric motors engineered to deliver an impressive 550 horsepower, the DuoPower drivetrain has the potential to propel a bus from 0 to 20 mph in under six seconds. With a seating capacity of 29, the bus provides a maximum range of 240 miles and a top speed of 65mph.
Previous studies considering battery electric bus operation and charging optimisation have assumed battery life of 8 years, (Wang et al., 2017), 9 years (Lee et al., 2021), 12 years (Li, Lo and Xiao, 2019) 3,000 charge/discharge cycles (Ke et al., 2020).
It's cheaper to run and maintain an electric bus.Fueling a bus with electricity is only about a third of the cost of fueling it with gas, which saves a considerable amount of money over time. Electric buses also have fewer regular maintenance costs—because they don't run on fuel, there's no need for oil changes.
Additionally, commitments from California and major transit hubs, including New York City and Seattle, to go 100 percent electric with their bus fleets have led to estimates that electric buses will make up one-third of the national fleet by 2045.
Although all battery electric bus batteries will store electricity in the form of DC, or direct current, power, the electric grid transmits and provides electricity in the form of AC, or alternating current, power. Therefore, a critical process of charging a BEV is the transformation of AC power into DC power.
