With the new range of hybrid heavy-duty vehicles, Scania takes an important step forward towards the total electrification of transport and services, continuing on its path to achieve its carbon emissions reduction objectives (Science Based Targets) in line with what has been established. in the Paris Agreement.
It does this by using a new hybrid powertrain which has been developed according to Scania’s modular philosophy. This solution in fact couples two electric motors together, combining them with the latest generation of the Scania Opticruise 2020 gearbox. The result is called GE281 and an e-machine with optimized power delivery and with the ability to manage up to 36 tons of total weight without the support of the combustion engine.
Since Scania’s new e-machine always supports the combustion engine, both at start and during acceleration, it is also possible for designers to revolutionize the latter by resizing it in displacement and power delivery.
This hybrid solution therefore guarantees fuel savings of up to 40% in urban operations, compared to traditional engines.
The ideal applications of the new electric hybrid (Hev) and plug-in hybrid (Phev) models – which can be equipped with different traditional propulsion and charging options – are refrigerated transport, concrete mixer outfitting and regional distribution. The new GE281 e-machine, operating in tandem with a Scania 7 or 9 liter combustion engine, also offers unique opportunities for transport solutions with minimal fossil fuel use for heavy industrial vehicles. “The GE281 is something new in the heavy truck sector – says Fredrik Allard, senior vice president and head of e-mobility in Scania’s sales & marketing department – With this fourth generation of hybrid vehicles, we are able to meet the needs of many more applications than in previous generations, demonstrating how sustainability and innovation are always at the top of Scania’s objectives “.
The latest generation of Scania hybrid vehicles is available as HEV and PHEV, in combination with cabs of the P, G and L series and as a chassis with chassis or semi-trailer tractor. The 7-liter combustion engine is available in three powers, as is the 9-liter engine. All Scania Euro 6 engines can be fueled with hydrotreated vegetable oil (HVO) and some are also compatible with FAME biodiesel.
Scania’s GE281 offers 230 kW of power (308 Hp) continuously and 290 kW of peak (389 Hp), while the maximum torque is 2,100 Nm. It has six forward gears and no traditional clutch, as this function is managed by a planetary gear, providing gear changes without torque interruption. This solution also provides excellent driveability at low speeds and the PTO can be engaged with the vehicle in motion, in both electric and combustion engine modes.
“The driving experience can actually be compared to that obtained with a car equipped with a dual clutch transmission – explains Allard – And with this solution, we can offer all the support functions that Scania customers are accustomed to, such as adaptive cruise control with active prediction and speed control on descents. Another important improvement is the regenerative braking, now continuous, very important considering that the e-machine is the primary braking source in these vehicles “.
Compared to the first generation of hybrid trucks, introduced in 2014, Scania has also made great progress in electric range. “At that time it was 2 kilometers, today it is 60” With the first generation – Allard added – Scania has begun to teach both us and our customers the potential of zero exhaust emissions, silent mode and substantial savings. of fuel provided by the hybrid solution. With the GE281 we have reached a new level.
The e-machine matches and often exceeds what the combustion engine can offer, thus creating the opportunity to downsize the internal combustion engine (ICE) and save fuel and weight. The ICE is motivated only by its ability to offer the autonomy necessary to travel longer distances between different activities. “The Phev models have batteries with an installed capacity of 90 kWh (3 batteries of 30 kWh), while the HEV version Fits a 30 kWh battery. The Scania Phev can be fully refueled in 35 minutes using a 95 kW direct current (DC) charger. This means that the vehicle can be charged in depots and during breaks or loading / unloading. of goods.
