Electric bus OEM Scania has introduced several innovations to its battery-electric bus platform.

The company’s new e-machine now offers four power options, as well as an integrated two- or four-speed gearbox. An additional battery option has been added, and a new charging interface at the rear of the bus is designed to deliver faster charging.

Scania e-machine is an integrated compact drive device, consisting of electric motor, inverter, gearbox and oil system. The oil system includes two oil pumps, which cool the e-machine and lubricate the gearbox.

The new e-machine has several power options to choose from, in order to suit various operating conditions, giving it more flexibility than the previous single power option. The customer can now choose among four different power options: 240 kW, 270 kW, 300 kW and 330 kW. The two- or four-speed gearbox improves the energy efficiency of the bus as well as its startability and acceleration, allowing it to move off smoothly and efficiently even under challenging conditions such as hills or heavy-duty operations. 

Scania is also introducing a three-battery-pack option with 312 kWh of installed energy, as well as a second charging interface at the rear of its buses. The rear interface delivers charging power of up to 325 kW at up to 500 A, significantly higher than the current front charging position’s 130 kW and 200 A.

“We know that bus operators face the push-pull effect of responding to emission regulations while striving to meet the specific demands of electric operations. Power needs, flexibility, charging time, energy efficiency and operational range are some of the key factors,” says Anna Ställberg, Head of Urban Solutions for People Transport Solutions at Scania Group. “The new e-machine, battery and charging options are being introduced with our customers’ challenges in mind.”
