Volvo has unveiled an innovative plug-in hybrid. The ReCharge Concept is a specially designed Volvo C30 with individual electric wheel motors and batteries that can be charged via a regular electrical outlet.
When fully charged the Volvo ReCharge Concept can be driven approximately 100km (62 miles) on battery power alone before the car’s four-cylinder 1.6 Flexifuel engine1 is needed to power the car and recharge the battery. The concept car also retains the Volvo C30’s lively drive thanks to an acceleration figure of 0-100km/hr in 9 seconds and a top speed of 160km/hr. Volvo claims that this plug-in hybrid car, when used as intended, should have about 66% lower emissions of carbon dioxide compared with the best hybrid cars available on the market today. Emissions may be even lower if most of the electricity comes from CO2-friendly sources such as biogas, hydropower and nuclear power. “A person driving less than 100km (60 miles) per day will rarely need to visit a filling station. Also, thanks to the excellent electrical range from a fuel consumption angle, the Volvo ReCharge Concept is exceptionally kind to the car owner’s wallet,” commented Magnus Jonsson, Senior Vice President Research & Development at Volvo Cars.
The only extra cost will be the electricity used during charging. The Volvo ReCharge Concept can be charged at any regular electric plug socket at convenient locations such as at home or work and a full recharge will take three hours. However, even a quick one hour charge provides enough power to cover just over 30 miles. During a journey the combustion engine starts up automatically when 70% of the battery power has been used up. However, the driver also has the option of controlling the four-cylinder Flexifuel engine manually via a button in the control panel. This allows the driver to start the engine earlier in order to maximise battery charge, for instance when out on a motorway in order to save battery capacity for driving through the next town. The Volvo ReCharge Concept combines a number of the latest technological innovations into a so-called “series hybrid” where there is no mechanical connection between the engine and the wheels. The battery pack integrated into the boot uses lithium-polymer battery technology. The batteries are intended to have a useful life beyond that of the car itself.
Four electric motors, one at each wheel, provide independent traction power. Four-cylinder 1.6-litre Flexifuel engine drives an advanced generator that efficiently powers the wheel motors when the battery is depleted. |
