Norwich-based Equipmake (www.equipmake.co.uk) has entered the final testing phase of its highly efficient electric-bus drivetrain, with performance and durability development set to finish by the end of the year.

The Brazilian commercial-vehicle manufacturer Agrale is scheduled to begin in-service trials of the vehicle in 2020 and then launch the electric bus in Buenos Aires in 2021.

The UK-based test and development programme is designed to ensure that the EBus drivetrain — featuring two APM200 motors at its heart, a latest-generation lithium-ion battery pack and an advanced power control system — works as intended.

The company’s innovative APM200 bespoke-architecture electric motor is believed to have the highest power/torque density of any automotive electric motor in the world.

The drivetrain also features a number of innovations that improve vehicle range and 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.

Equipmake’s managing director, Ian Foley, said: “We are very excited to be reaching the final phase of EBus powertrain testing, ahead of in-service trials in Buenos Aires early next year.

“The drivetrain has performed exactly as expected so far, but as we complete our UK-based durability testing, our team of expert engineers will be making sure that it continues to hit every target in order to fulfil its demanding application in Argentina.”
