Batteries are gone, soon the car

Tuesday, January 23rd, 2018

On Saturday, I delivered all of the large format batteries to a friend of a friend (sold some, gave others). No more big batteries in the house. I’m now gathering up the various parts and documentation so the car can be donated to the local University EV club.

Delays in research

Thursday, May 26th, 2011

Sorry about the delays – had a week-long face-to-face meeting, compleate with a BBQ at my house and a dinner at a local restaurant. Busy busy busy. I really hope to have time this weekend for reviewing the motor.

McMaster’s site rules!

Tuesday, November 3rd, 2009

I had been having some trouble trying to find a local source for braided copper grounding straps suitable for making battery interconnects.  No idea why it is hard to find, but there it is.  Sean suggested I try a few sites, and one of them is  Wow.  460,000 different parts, just about anything you can imagine you would need for just about anything.  (who me? impressed?  Heck yeah!)

Anyways, I ordered the flexible braided copper cable (equivalent to 2/0 AWG) and melting pot for solder last night.  This afternoon – they were delivered.  O_O

Wow.  Color me majorly impressed.

Terminal and Relay Diagrams

Thursday, September 17th, 2009

Well, now that I’m getting ready to hook up the high voltage, I feel good enough about my terminal block and relay hookup diagrams.  I’ve put it into a PDF for your viewing pleasure, and it can be found here: 914_AC24_Layout_V1.  I hope this helps with other people trying the same sort of madness.  😀

New Relay Panel

Sunday, August 16th, 2009

Well, as I mentioned in the last post, I am completely rewiring everything.  About the only thing remaining in the same place are the battery racks and the wires going from engine to mid compartment.   I’m still cleaning up the wiring in the rear trunk…and as you’ll see from the picture I’ve got the controller out (for reprogramming).

I’ve also moved the potbox to a location closer to the relay panel (and out of the most nasty of the weather).

Also note the new battery (red), charger (green) and DC-DC converter (black)…so I’ve been keeping busy.  🙂

Front Relay Board

Thursday, April 16th, 2009

I just got through wiring up the front relay board (and found I had put the wrong relay on the rear relay board in the process).  It actually looks like I know what I’m doing!
