Make mine an e-bus
The global electric-bus market is changing rapidly as cities make increasingly ambitious fleet-electrification commitments. In 2017, there were some 385,000 e-buses on the roads worldwide – with 99% of them located in China –with around 13% of the total global municipal bus fleet electric, according to the Electric Buses in Cities report from the C40 Cities Climate Leadership Group and Bloomberg New Energy Finance.
The biggest e-bus deployments continue to take place in China, though a number of US and European cities are also on the move. Notable projects include the city of Shenzhen’s fully electrification of its 16,500 buses, Beijing’s target of having 10,000 e-buses on the road by 2020, Los Angeles’ move to transition its fleet of 2,200 buses to be fully electric by 2030, and London’s plan to have all new single decker buses zero emission by 2020.
As far as top-ups go, slow, overnight charging at the depot is the most popular option, followed by a combination of depot charging and fast-charging top-ups – pantograph or plug-in – at the terminal and bus stops. Combining depot charging with fast charging en route – at the terminal or bus stops – allows for smaller batteries which should lower the upfront cost of the bus.
Chinese automaker BYD has posted a series of electric bus contract wins recently including an order for 4,500 vehicles to transport companies in Guangzho, while the company has more e-buses on Canadian roads than any other.
