This is something I thought to do to make use of an aged motor once more.
I may be able to pour money in as i go, might also eventually have support from family business, advertising purposes.
I would like to create a one of a kind heavy DC electric vehicle, using what i have on hand.
I understand too little about circuitry and code workings to do this alone, but Ive found multiple works online that have helped enlighten me a little, like using dual IGBTs in a H-bridge circuit along with current sensors and dsPICxxxx controllers to be able to take variable dc input voltage within a set range and then convert to a variable dc output voltage within a set range based on analog input(from an accelerator pedal). (No clue how to wire or code this)
Optimally, this should also be able to work in reverse to charge battery when braking/slowing with idle.
I have an old industrial DC shunt motor (pic below), and an available chassis with suspension installed already(will figure out mounting later and gears/differential).
I have no idea how much range id want, or even be able to get out of this theoretical ev, perhaps 50 miles to start?
For those with a good guess on how far i could get, heres the proposed battery pack setup i thought up to work off of:
Pack idea 1:
A 100 series 30 parallel pack (3000 count) of 21700 samsung 50E cells totalling approx 50kWh/144Ah at a range of 250V-420V with a max safe amps draw of 150.
Not sure if i want to go with protected cells, or use bms systems...
Also thought up a much cheaper, and lightweight pack for short drag strip use:
Pack idea 2:
A 58 series 6 parallel pack (348 count) of 21700 samsung 40T cells totalling aprox 5kWh/24Ah at a range of 145V-243V with a max safe amps draw of 210.
I figured if i go with this build, i wouldnt need to worry about motor drawing too many amps, since it would only be used for a short moment at proper voltage anyways, and with lighter weight car build overall, load might not force higher than rated amps on motor.
Additionally, I could possibly get away with directly powering motor, with no controller besides what is essentially a go button.
So what i need is a working circuit and code build that would suit the specs for the regulator/controller, and for both builds; a charger device for standard 120v or 240v ac wall outlet.
I can provide additional photos if needed, like wires from motor like control leads.
Thanks for reading this wall of text, and hopefully ive provided enough details for anyone interested in figuring this out.
