U.S. Electricar, Inc. 25 July, 1997 Test Results on Can Pulse Battery Charging Unit
Two different trucks were used in testing the results. a) GR. w/225R15's, 120 volt sys: 20 each USB145 (matched)
Truck Two (#2) was a mexican built, pre-production (one of 15 built), RHD, configured as so: Summary: On both #1a) and b), and the #2 truck, the average specific gravity at full charge went up .02 or more. The usual charge on the USB145's puts the batteries at about 1.28 to 1.29. A few charges with the Can Pulse unit would leave them at 1.31 to 1.32. Every .01 rise equals a 3 to 4 mile increase in range. The Specific Gravity to distance curve would also get steeper. It would go from a slope of 3.55 to 4.50. On the 120 volt systems, the range would increase from an average of 41 miles to that of 49+ miles, ending with the same specific gravity remaining. On the 144 volt system, the range went from about 65 miles to over 74 miles. It could possibly go further, but the pack on the 144 volt truck (#1b) is mismatched and severely abused. (A matched set of Excide CG5's will be installed and tested next week). Current range on the #2 is 53 miles unloaded, and 42 miles with a static 1200# load. The mileage drop with load is due to the low differential gear ratio. A higher gear ratio will provide better ranged loaded. Data and graphs are on file for review. Sincerely.
