The UK’s Transport for London (TfL) is launching long-range, zero-emission, all-electric BYD double-decker buses on revenue service routes.

London deputy mayor of environment and energy Matthew Pencharz formally received the first all-electric bus from electric vehicle manufacturer BYD Europe at a special ceremony at London City Hall.

To start with, TfL is deploying five all-electric double decker buses on route 98, which is known to be a ‘pollution hotspot’ in London.

BYD will also help deploy fast-charging equipment at Metroline’s Willesden Bus Garage in north London.

Pencharz said: "The running costs are much lower and some of the maintenance and operations costs are much lower on the buses.

"Also, these buses are zero-emission, zero-tailpipe-pollution, and that is a huge benefit for Londoners."

As well as designing and developing the buses according to TfL’s specifications, BYD will also be responsible for providing driver training to the bus operators.

"The running costs are much lower and some of the maintenance and operations costs are much lower on the buses."

The 33ft-long, air-conditioned bus will be able to accommodate a total of 81 passengers, including seats for 54 passengers.

BYD managing director Isbrand Ho said: "BYD is pleased to partner with Transport for London to provide these zero-emission, advanced technology buses that will help improve air quality in the greater London area and will also provide costs savings."

The all-electric double-decker buses feature BYD-designed and made iron-phosphate batteries that can generate 345kWh of power.

These batteries come with a 12-year battery warranty, which is the longest available electric battery warranty.

The batteries require a single daily recharging for four hours, with a single charge supplying for more than 24h and up to 190 miles of typical urban driving.

TfL intends to charge the buses overnight using low-cost, off-peak electricity that would add to more cost savings.
