Temperature test triumph for Volvo C30
The Volvo C30 Electric has proved its worth next to conventional models after it performed trouble-free in -20° conditions.
Several new test methods have been developed for Volvo’s electric vehicles to keep it in line with the rest of their range.
"We must ensure that the C30 Electric performs as intended when driving, parking and charging in a variety of conditions, from normal to very cold or hot,” said Lennart Stegland, director of Volvo Cars’ Special Vehicles. “Northern Sweden is the perfect place to do sub-zero temperature testing.”
A special climate system controls the temperature of the battery pack, cooling or warming it whenever necessary. The electric motor and power electronics are water-cooled while an innovative solution makes it possible to get comfortable heating in cold winter conditions without compromising the battery driving range.
Climate control in the passenger compartment takes place via a bio-ethanol powered heater. The car’s ethanol tank can carry 14.5 litres of bio-ethanol. It is also possible to run the climate unit on electricity from the batteries. In electric mode, an immersion heater warms up the coolant in the climate unit.
"The driver can program and control the climate unit to suit the trip,” explained Stegland.
“Ethanol is the default mode that is used when the battery capacity is needed for driving, extending mobility to its maximum. However, on shorter distances electricity can be used to power the climate system.”
