The Electr02 is operational with 0-60 video.
After some frustrations and confusion I was finally able to get all the electric systems functioning. Most of the confusion was related to the Can-Bus system of communication between the Master Control Unit(MCU) and the subsystems like dc to dc converter, high voltage charger, and the rest of the car. The vendors who provided the equipment were very helpful and walked me through the setup despite my relative ignorance. After several weeks of non communication between can-bus items I had a major DUH moment, if a 120ohm resistor is required on both ends of a can bus high and low, I probably needed two on a home run 'non loop' to get the right resistance. Immediately after adding the second resistor the communications worked perfectly and the car not only took a charge but had data and information from the subsystems communicating with the MCU.
This was the first signal, a functioning charger hitting a test setting first go. I won't be limited to 1500w, in the future I expect to pump 3kw through this charger, but its early days so I didn't want to push anything. Once the Can-Bus systems functioned, everything functioned as expected.
Because I am a grown child, I immediately did a 0-60 run. Here were my settings for this run:
Motor Max V - 150V (can go up to 175 with active cooling)
Motor Max KW - 100 (could try up to 150 but will smoke brushes)
Motor Max Amp - 600 (not sure this max yet)
Battery Max Amp - 800 (1000a max)
Battery Max Voltage - 270v
Battery Min Voltage - 200v
Amps/Sec Ramp Rate - 1500amps
0-60 7 seconds
Next steps:
- Install camber plates to remove front tire rub on the fender.
- Ducted fan cooling system for motor and liquid cooling loop for controller and subsystems.
- Create permanent locations for battery charger, dc to dc converter, contactors and fuses from the top of the battery to the trunk and under hood where applicable.
- Rear sway bar increase to handle 300lbs of weight in the rear seat location.
- Patch and tidy up rear trunk floor where old batteries were located.
- Tidying up the front clip, fixing surface rust, patching cut panels(cut to fit original battery), touch up paint around repair spots.
- Chiller plates for battery.
- Flat floor and aero modifications.
The car currently weighs 2200lbs, has an ancient forklift motor, and will likely smoke anything but the most tarted up m10... for a mile until it overheats.
