Range and Efficiency

Time Posted on September 15, 2010 User ChargeCar Team

The Civic was taken out for a long drive Tuesday afternoon.  From the garage, to downtown via Bigelow, back out to Squirrel Hill, Pocusset to Serpentine Drive, then approximately 10 miles through Schenley Park, and back to the garage via downtown and Bigelow.  This was a reasonable combination of highway and urban driving.  The total trip length was about 30.2 miles.  The netbook in the passenger's lap reported a net charge usage of 6.62 kWh (with 19% regen from total), giving 4.56 miles per kWh!  [Thought: Ah may be a better indicator of battery usage than kWh]  The pack voltage did not sag a large amount and the test was terminated because of time.

The car managed 70 mph on a level stretch of the Parkway, drawing ~280 A in 5th gear.  This is only half of the available peak current, so the speed capability should be substantially higher (on level ground).  The Civic also did 55 mph uphill on Bigelow coming from town without pushing too hard.

The total energy to recharge the Civic was 7.96 kWh; charging efficiency is around 83%.

Very encouraging results.  We think that we can go even further than 40 miles - a 45 mile practical range would be very nice indeed.  More range tests will be happening soon, we'll keep you posted!
