142 Electric Conversion
Ekelund with his grandson
In Växjö, Sweden, many heads turn when the red Volvo 142
quietly glides past. The vehicle is converted to electrical operation
by the pensioner Kjell Ekelund. The battery-powered Volvo 142 only costs a
few dollars to "fill up".
His Volvo has a top speed of 80 kilometers an hour. The batteries
are fine for an hour of city driving. The low cost of driving is
an advantage - a single charge costing around a dollar and open road travel is about one
The Volvo was bought new by Kjell's father in 1972. During the past 15 years has been
stored in a garage in the Öland country. Kjell wanted to
restore the family treasure, but an ordinary renovation was never
I thought it was interesting to put an electric motor for my grandchildren's sake. With "my grandfather's electric car", they
can see what is possible. For my part, I wanted to see if it is possible to
convert old cars to electricity, says Klell Ekelund.
With a background as a foreman at Volvo in Växjö, he possessed the right skills for a
conversion. Kjell chose a three-phase motor of 7.5 kilowatts to
run the car, a type used in the industry. A converter converts the DC
battery voltage to AC voltage.
The electric motor has dual output shafts. On one side is a flywheel and clutch fitted - the other shaft drives the car 12-volt generator. The electric motor
is only replacing the petrol engine, otherwise the car as standard with 4-speed gearbox. Kjell's solutions are different from the modern electric car manufacturers, but the system works.
It is completely his design-concept. "I wanted to test if it could be run in this way with so little
power output that I have - and it works better than expected, "he says.
Kjell chose a battery pack consisting of 30 units of maintenance-free 12-volt lead-acid batteries. They weigh 250 kilograms which is quite
low for electric cars here. They are divided between the location of the fuel tank, and
the engine compartment. That means interior space is completely intact.
The conversion took approximately 300 hours used and the entire renovation, including painting cost 60,000 SEK. Of the total cost was approximately SEK 25,000 for batteries, and 20,000 SEK
for the motor and converter. (1000SEK=US$140)
Kjell Volvo uses on a daily basis and it works perfectly in town. He says that interest has been great when the car has been shown in various exhibitions.
Many people travel 20 or 30 kms back and forth to work. Then it would be ideal to have one of these as
second car, says Kjell Ekelund.
