20230226 Elec-Trak E15 Work Session Two
: Who: Jay Donnaway (SeattleEVA.org President) and Lightning Ryan Fulcher (In plaid jacket)
* This machine was originally restored in 2011 by Gary per: https://www.builditsolar.com/Projects/Vehicles/E15ElecTrak/Main.htm
* 38:37 https://youtu.be/YWcgz8Cot5U ElecTrak E15 20230226 164052 016 RestoreRearAccessoryMountCompatibility
** Rear Steel Battery Box has an aftermarket 1/2" plywood box built outside the original.
*** This wood box is covering the rear stabber slots that accessories use to mount.
*** We cut out just enough of the wood box material so to regain access to the rear stabber slots.
*** The rear winch lift now fits, although it does not completely seat over the rear bumper and pin into place.
*** Will need to devise a new pinning mechanism. A pair of small C-Clamps for example under the bumper could do the trick.
**** Or it should be possible to also remove more wood box so to expose the rear bumper, but pinning would still be obstructed.
**** OR! There is a hitch with a center pin that probably lines up with the accessory winch, how about using that, DOHH.

** Began @8:55-27:30 (maybe 25% driving) ##18.5 *.25 ==4.6minutes
** Continuous Driving @27:30-29:01 ~~1.5min
** Continuous Driving Pt2@0:00-8:30 (Check toaster heat) ~~8.5min
** Testing an accessory motor @9:45-13:00
** Continuous Driving @13:00-14:35 (Check Traction Motor Heat) ~~1.5min
** Parking Driving @19:10-19:55 ~~0.75min
** 4.6+1.5+8.5+1.5+0.75 ~~==32.95min (33minutes) Lets just call it 30minutes.
*** Were Recharged at 10a in 2:13:01 adding 10.7Ah, Ending deltaV was 63mv.
*** This means we averaged ~21.4Amps of draw for the half hour of runtime.
*** At @42v(899Watts) resting or @38v(813Watts) under load.
*** Or Consumed 10.7Ah @42v(450Wh) or @38v(406Wh) consumed over the half hour.
*** Total Capacity of these LiFePO4 are 50Ah @42(2100Wh) we used about ~20% which is 420Wh checks out.
* So we can project that if running an accessory doubles the load, about 1 full hour of runtime as is.
** Am very much considering doubling the pack size and moving to beefier connections and copper for next time.
