Alexander Dennis Limited (ADL) and BYD Europe jointly announced their electric vehicle partnership supplied 10 electric double-deck buses to National Express for operation in Coventry, England, as part of a wider investment in 29 zero emission BYD ADL Enviro400EV.

Following the operator’s pledge to never buy another diesel bus, ADL has supplied another 10 zero-emission double-deck buses to British transport group National Express. The latest clean buses have entered service in Coventry, linking the city center and University Hospital.

Built to National Express’s Platinum standard, the 35-foot BYD ADL Enviro400EV offers extra legroom for up to 65 seated passengers as well as USB chargers and free Wi-Fi. An advanced heat pump system ensures that saloon heating power is supplied efficiently from the main batteries without unduly impacting operational range.

To simplify the transition to electric buses for National Express, the 382kWh BYD Iron-Phosphate batteries on each vehicle are maintained by Zenobe Energy, who provides them to the operator along with the charging system at the depot and a software platform which helps monitor and optimize energy use.

Coventry’s new fleet of 10 electric double-deckers follows 19 similar vehicles for Birmingham that ADL supplied earlier in the year.
