Alexander Dennis has unveiled its first next-generation Enviro400EV battery-electric double decker built to Transport for London (TfL) specification.
The Enviro400EV for London is fitted with 472kWh batteries as standard, which the manufacturer is now able to warrant for 14 years or 1 million km, whichever comes first, under normal operating conditions in the capital.
This allows the zero-emission bus to cover two consecutive seven-year route contracts without a need for battery replacement.
The batteries can be fully charged in three hours through a DC plug connection, or even faster with optional roof-mounted connector rails for pantographs.
Energy from the batteries powers the Enviro400EV through the heavy-duty version of the Voith Electrical Drive System.
A 354kWh battery capacity version is also available for routes where range is not as critical.
The next-generation Enviro400EV for London is 10.5m long, with a shorter wheelbase aiding manoeuvrability in the capital’s dense traffic and has TfL’s standard interior layout with a wheelchair bay accessed via an electric ramp at the centre doors.
It seats 62 passengers on high-backed seats, with rear rows on both decks reduced to four seats to increase passenger comfort.
Total capacity is up to 87 passengers with 472kWh batteries, or up to 96 passengers with 354kWh batteries.
Ben Werth, Group Sales & Business Development Director for Alexander Dennis, said: “In addition to detailed route analysis, we have conducted extensive tests with our supply partners at the cell, module, pack and vehicle level, which have shown that 99% of London routes can be fully serviced with our 472kWh battery.”
