Developed in-house, Equipmake’s Zero Emissions Drivetrain (ZED) features its proprietary electric motor, inverter, and power electronics combined with the latest lithium-ion batteries. For the Streetdeck, Equipmake pairs its HTM 3500 motor – delivering 3,500Nm of torque at 1,000rpm and peak power of 400kW, integrated into the prop shaft without the need for a separate transmission – with a Semikron SKAI inverter and a 436kWh lithium-ion battery, capable of delivering up to 200-miles of range.
A feature of the ZED is its patented, ultra-efficient thermal management system, which maintains the battery pack, motor and inverter at an optimal temperature, therefore maximising vehicle range. An advanced water-glycol cooling circuit provides interior heating during cold conditions with captured thermal energy.
Once the battery has been depleted following a duty cycle, it can be recharged at the depot via a CCS DC charging point.
Ian Foley, CEO, Equipmake said: “The Wrightbus Streetdeck is one of the most popular double deckers on UK fleets and the conversion of these buses will not only have a huge positive impact on local air quality but provide operators with a vehicle with lower running costs and a better experience for passengers and drivers.
“We’ve worked incredibly hard to develop this stand-out electric repower solution for the Streetdeck and the results are sector-leading. Our Zero Emission Drivetrain technology has a crucial role to play in accelerating the transition to a fully electric UK fleet – and we look forward to converting as many of these vehicles as possible in the coming months.”
