Finnish innovators entering electric truck market

Two Finnish businesses have teamed up to disrupt the electric truck market with a new hybrid system capable of delivering more than 1,100hp and 5,000Nm of torque.

Launched at this year’s Kuljetus transport tradeshow in Finland, the system could mark an “important milestone” for hybrid electric power in the heavy transport sector, local companies Visedo and Sisu Auto announced.

According to electric bus specialist Visedo, the electric power system was originally developed for a proof of concept vehicle: The parallel hybrid drive draws power from both an electric motor and a diesel engine connected via the same axle – making for a 850kW (1,140hp) power rating and more than 5,000Nm of torque.

The companies managed to locate electric motor right between engine and gearbox, in turn ensuring “simple assembly with no need to alter the existing chassis or suspension structure”.

Similar to a hybrid car set-up, the electric motor assists the diesel engine during peak periods and charges energy storage during the off-peak via super-capacitors.

The solution also enables the use of the vehicle with or without electric power since the drive line is mechanically continuous from the diesel engine to the axle.

Visedo System Solutions Manager, Risto Tiainen, said he was proud of the prospect of delivering “breakthrough power and performance while saving fuel and reducing emissions”.

He added, “The revolution to electrify the world’s diesel transport is already underway. After delivering pioneering hybrid and electric power for passenger buses, Visedo is proud to be powering the next generation of cleaner truck transport solutions.”

Visedo had previously developed an electric drive system to work in parallel with Mercedes-Benz’ OM471 and OM473 diesel engines, which are used in the Sisu Polar truck range.
