Alexander Dennis Limited (ADL) and BYD Europe say their electric vehicle partnership has supplied ten electric double deck buses to National Express for operation in the British city of Coventry, as part of a wider investment in 29 zero emission BYD ADL Enviro400EVs.

The batteries on the vehicle and charging infrastructure will be maintained by Zenobe Energy, one of the UK’s largest owner-operators of mobile and stationary batteries.

A heat pump system ensures saloon heating power is supplied 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, which provides them to the operator along with the charging system at the depot and a software platform that helps monitor and optimise energy use.

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

“The commitment to a zero emissions fleet from National Express is as commendable as it is bold and is indicative of more and more Public Transport Operators, who see electrification in particular as a viable long-term solution for their scheduled routes,” said BYD (UK) MD, Frank Thorpe.

“Our BYD ADL Enviro400EV double decker is a proven product, already in service with a growing number of customers, delivering tangible operational benefits and providing safe, quiet, emissions-free transport for their passengers.”

ADL is a subsidiary of independent global bus manufacturer, NFI Group.
