I'm using 98 3.2V lithium iron phosphate (LiFePo4) cells, for a total system voltage of 313.6V. The cells are 60 amp hour, so my system's total energy is about 18.8K watt hours.

I started a thread in the new members section that gives more info: https://mustangforums.com/forum/new-...7-e-stang.html

That is going to be awesome!

two words (I think) Too Boocoo

you're going to twist that car into something that resembles a DNA double helix model ...were talking like a 1000FtLbs torque here

You're right, I'll have to be careful -- that's why I won't use first gear.

Also, I'm able to program the motor's controller to keep things within certain parameters, so it won't get out of hand.

There are some great videos of EVs at drag races -- look them up on YouTube, it's pretty cool stuff.

yeah, i saw a s10 on pass time one time, that thing ran like a 9.7 or something

I figured the speed controller could be programmed for max amp draw.

Im sure you did the math...the batteries will never pay for themselves when cost is measured against fuel prices right? 5k+ worth of lithium right?

How do you plan to charge them and at what C? You have a total of 60 Amp hours right? Im guessing the lithium-iron is rated for 1c recharge with 20C discharge...Finally what about balancing cells do you have a balance system setup?

Keep us posted...good stuff.

i am so cornfused right now

C rating all up in yer biz?...hit up wikipedia and find out what it is!

The batteries cost almost $10K But they should last more than 10 years. Whether or not they'll pay for themselves depends on what happens to the price of gas during that time. The good news for me is that battery replacement should be about the only 'maintenance' cost for the car during that time -- no oil changes, tune-ups, engine rebuilds, filter changes -- nothing. EVs are practically maintenance free.

These batteries have a max charging rate of 3C and max discharging rate of 3C (constant) / 10C (pulsed). I have a 20A charger, and I'll typically only use about 1/2 the energy (i.e. drive only about 30 mile/day) so recharging should only take a few hours -- and I'll be able to quick charge at home (on a 240V outlet) in half the time.

The car will also have a battery management system (BMS) to ensure the cells stay balanced during discharge (the smart charger will keep them balanced during charging). I'll also have a monitoring system to track cell voltages and make sure everything's good.

By the way, so we don't hijack this thread, I started an EV build thread in the classics section. I'll cut-and-paste this post and we can continue there.

Well since it looks like the last time I posted in this thread was about a year and a half ago, and I moved the pictures around it's time to re-post.
