Mo's 1996 Corvette Conversion - Update

It has been a while since I posted my recent updates. So I thought I would share.

I started with a 144 volt system with a Curtis controller and a 4L60E automatic.

I had put about 3000 miles on the car in the past year it has been on the road.

Last July I started ramping things up and managed to get a Zilla HV 2K controller the short time that they were back in business.

For now here is how the Zilla is placed:

The total battery count is 10 I have updateded with a battery rack fo the top 4 batteries shown strapped down.



I rearranged the batteries to get 10 in the rear versus the original 6:



I also replaced the Automatic with a ZF6 six speed transmission:



I went clutchless and I have no problems shifting, I generally start in first and run through 50 MPH in second. I have reached 65mph with no issues.




I am running 20 Optima D34M's total.

what's the performance like with the zilla?.. have you ramped up the amps to 1000?

It is a 2k Zilla, I'm only pulling about 500 amps from the Batteries I set the motor for 154 volts and 800 amps. ( At this point the batteries are the weak link.) Whether it is a true valid test or not the batteries with a 500 amp load individually sag to about 11 volts. At WOT the pack sags to about the 80% mark.

I'm still running tests for the best acceleration. I'm hitting 0-40 in about 7.7 seconds. 0-50 is 11.9 seconds. I have had the car over 65 mph and still climbing. At cruise at 50 mph I'm at about 100 amps draw.

I have my hairball in for a software update, it should be back next week... So these numbers only reflect running 16 batteries
.
I expect that with 20 batteries these numbers should drop some.

I would love to run lithiums I just have not sat down long nough to see what they will cost. Obviously the weight reduction would be a major plus...

75 100ah CALB cells at 3.2 nominal gives you 240V pack, over 24KWH, would allow 30 seconds of 400 battery amps with less voltage sag, short bursts higher than that, and cost about $10K. TS and Hipower would be a little less. Break open that piggy bank :D
