Fuel consumption is reduced by over 80% and the total energy consumption by over 60%. The results of the field tests being conducted in Gothenburg show that Volvo Buses’ plug-in hybrid more than meets expectations.
“Our performance results are even slightly better than we had anticipated. The plug-in hybrid consumes less than 11 litres of fuel for every 100 kilometres. That’s 81% less fuel than the equivalent diesel bus consumes,” says Johan Hellsing, who is the Project Manager for the field test at Volvo Buses.
Moreover, the figures for the overall energy consumption, including both diesel and electricity, have exceeded the target. Here, the plug-in hybrid gives an energy saving of 61%, compared to a corresponding diesel bus Euro 5.
The field test in Gothenburg began in June 2013 and includes three plug-in hybrid buses, whose batteries are recharged at the terminals. This makes it possible for the buses to run on electric power for most of the route.
Volvo’s plug-in hybrid bus:
The bus is fitted with an electric motor which is powered by a lithium battery. It also has a small diesel engine.
The bus is recharged from the mains power supply via an energy storage unit mounted on the roof. It takes 5 or 6 minutes to recharge.
The bus can run exclusively on electric power for approximately 7 kilometres – without any noise or emissions.
