Torque converter enables SCHERM Group’s 65-tonne terminal tractor to reach maximum speed as quickly as possible, saving 22 tonnes of CO2 per year
For nearly two years, SCHERM Group has used a 100 per cent electric Terberg YT202-EV terminal tractor with an Allison fully automatic transmission to efficiently deliver materials to the local BMW Group plant. The results have been positive and another BMW supplier has adopted a similar Allison-equipped truck.
The fully-electric tractor is equipped with a three-phase synchronous motor (614 V) with a maximum power rating of 138 kW (188 hp) and a fully automatic Allison 3000 Series™ transmission. The Allison Automatic is the key to the driveline: the truck has to launch with a gross combination weight (GCW) of up to 65 tonnes and achieve maximum speed as quickly as possible to meet the tight delivery schedule. This is made possible by the transmission’s torque converter that multiples engine torque during start-up and acceleration.
“The electric truck has proved itself in city distribution and the just-in-time delivery for BMW is working fluently,” said Ulf Frenzel, fleet manager for SCHERM Group. “The Allison transmission makes it possible to specifically use the power of the electric motor in the best manner. And the e-truck can be maneuvered easily and is extremely easy to drive.”
Additionally, the Allison transmission eliminates power interrupts for increased productivity – even with a smaller engine. Without the Allison, a direct drive with a larger and significantly more expensive engine would have been necessary. The transmission’s Power Take-Off (PTO) provision is used to drive the hydraulic pump, which saves an additional electric generator.
“The Allison transmission proves its reliability and ease of use in daily operation” said Frenzel. “In addition, we have shorter maintenance downtime than with a conventional diesel vehicle, better productivity and therefore we are much more efficient.”
The 65-tonne electric vehicle commutes in two-shift operation eight times per day, five days a week, between the BMW plant in Munich and the SCHERM logistics centre 3 km away. Since it was put into service in 2015, the vehicle has completed over 3,000 trips and covered approximately 17,000 km. Over the last two years, more than 8,000 litres of diesel and 22 tonnes of carbon dioxide have been saved.
“We are really satisfied with the e-truck,” said Frenzel. “We wanted to prove that electric mobility also works in freight transport, and we achieved our goal.”
Following SCHERM’s success, Elflein Spedition & Transport also began using a similar Allison-equipped electric truck for short-distance transports to the BMW Group plant in Leipzig in November 2016. This vehicle will save 21 tonnes of carbon dioxide each year.
