Electric cars are getting more and more popular as their prices are decreasing. It will not take long for them to be direct rivals to our conventional internal combustion engine powered cars. However, it is completely different story with trucks, as they need a lot more energy and must be affordable for companies. Now Daimler Trucks revealed a Mercedes-Benz Urban eTruck.
Daimler says that between 1997 and 2025 the costs of batteries are likely to fall by 60%, while power will increase. This makes electric truck viable, as long as they are used having in mind their powertrain. Daimler Trucks developed such machine, based on a heavy-duty three-axle short-radius distribution truck from Mercedes-Benz. This new electric truck is driven by electric motors directly adjacent to the rear wheel hubs.
These motors output 2 x 125 kW, while the peak torque is 2 x 500 Nm (gearing increases it to 11 000 Nm). Three module battery pack has a total capacity of 212 kWh, which provides a range of up to 200 km., which is generally enough for a delivery round around the city. Battery pack is customizable to fit all the needs from different companies, but as is it can be charged in 2-3 hours.
Obviously, electric truck is heavier, but green credentials compensate for the difference and do not contradict with regulations. Mercedes-Benz Urban eTruck is environmentally friendly and silent. In the future it could tackle a vast array of different tasks in the urban environment – from waste disposal to supplying goods to industry or taking away finished products. It definitely proves that electric trucks nowadays are finally economically viable option. However, Daimler had been testing light electric trucks for quite some time now.
Fuso Canter E-Cell has recently completed trials in Portugal and Germany. These light-duty trucks will be available for customers and are rather practical. The motor outputs 110 kW, while the peak torque is 650 Nm. Batteries store 48 kWh of energy and provide truck with a range of over 100 km. Furthermore, it can be charged to 80% of its total capacity in just one hour. Electric and hybrid trucks are already a reality and it is likely there will be more of them in the near future.
Discussions about economic viability of an electric truck have been on-going for quite some time. But now Daimler Trucks is taking a step forward becoming a pioneer in the field. Although it will take some time till the Mercedes-Benz Urban eTruck will start working in the streets, the future for electric trucks seems to be very promising.
