another EV mystery
An unusual occurence this morn. I pulled out onto the road in 1st, shifted to 2nd and the car felt doggy. Pushed on the notgas pedal and noticed the amp gauge was displaying a low reading. As the car gradually gained speed, the amp draw increased. Normally the draw would start high and decline as th...
range
Jeremy; You're right, 50 volts is too low. However, that reading was seen while trying to climb the last hill before home with almost fully discharged batteries. These batteries are almost new (6 mo) and none of the terminal connections have ever been hot or even warm. The difference between open ci...

The electric Porsche does not go as far as I think it should. I have an 84V system (14 golf cart batts) and each battery is rated at 192AH. If I assume 80V average this should be slightly over 15KWH. I have a watt-hour meter on the charger and have determined that the car uses (depending on how it's...
hot motor
The motor is now at ambient and will be for a while. On the way home from the coffee shop this morn, the controller failed in a most violent manner. The side blew out, coating all nearby bits with black soot and filling the car with vile smoke. It sounds unlikely, but I wonder if the motor heating p...
hot motor
The more I learn the less I know. It has to end. The comm checked ok visually and the motor turned freely. My next step was to get a temp marking pencil with a melting point of 300F. It's soft and crumbly so I taped a chunk to each side of the motor case with duct tape and went for a drive. With gea...
hot motor
Thanks for the replies. I don't think I have anything binding or dragging and in any event, that would show as an increase in amp draw. This car, with Nokian tires, will coast for over 1/4 mile from 30 mph. The factory guy returned my call today and thought that perhaps a commutator bar had lifted. ...
Nigel The Porsche will top out at abt 60 mph or 95km/hr in 5th. It might go faster but at that speed it was pulling over 300A which caused the motor to heat quickly. Do you have volt and amp gages in the Rover? Are you running out of hp or motor rpm? tommyt ps Once upon a time I had a 2000TC - what ...
Hot Motor
My Porsche (924) conversion has suddenly begun to run hot. Several days ago, on a level stretch of road where I have in the past observed 300F, I noticed the motor showing 400F. Suitably alarmed, I backed off and within seconds had the temperature back down to 350F. Since then I have watched the tem...

In the colonies (New Hampshire) is a company called Electric Vehicles of America run by a Bob Batson. I don't know if he deals internationally, but he puts out a 1/2" (12.7 mm) thick sheaf of information. www.EV-America.com
