The latest version of EBus powertrain has been unveiled at Busworld Europe by Equipmake, electric chassis that aimed at double decker applications.
All EBus drivetrains feature two APM200 motors at their heart. The APM200 is Equipmake’s innovative spoke-architecture electric motor, bred from F1 technology and believed to be the highest power/torque dense production automotive electric motor in the world. These motors, which each produce 220kW and 450Nm of torque are mated to a two-speed gearbox, while proven Semikron SKAI inverters and the latest generation lithium-ion battery cells complete the fully integrated platform.
But it is the integration and energy management that really sets EBus apart. The drivetrain features a number of novel innovations, that not only improve range but reduce capital cost. By optimising the heating and cooling of the vehicle and maximising overall energy efficiency, the bus will have enough range for one day’s running without the need for charging. In this way, the vehicle won’t be reliant on infrastructure and can maintain flexibility of route.
For operators, it also reduces initial expenditure as the EBus platform’s efficiency means it can use a smaller battery pack bringing overall cost down. Equipmake estimates that within 8-10 years, its EBus platform will be cheaper to run than a conventional diesel version. To charge the vehicle, the operator simply needs access to a standard three-phase supply, which will fully charge the vehicle in around five hours. However, the powertrain also supports fast charging – and has an onboard charger.
Equipmake has already entered the final testing phase of its low-entry single decker EBus platform, with UK-based performance and durability development set to finish at the end of the year. In-service trials of the vehicle will then begin in Q1 2020 by Brazilian commercial vehicle manufacturer, Agrale, who will launch the electric bus first in Buenos Aires, Argentina in 2021. Equipmake will begin double decker chassis trials later this year.
