Ordered a ElCon 2500 charger today 128 volt.

Gonna try  :mA<: one of these BMS boards. cheap 22 bucks

Here is more battery porn, two of these will fit in one box so I will only be using the front
boxes right know.

These are real nice to cut off all the surrounding metal and still maintain
all the clamping of the original pack. One done three to go. oh, they will
all fit in just the front boxes, gonna have to find four more units.
I am gonna use copper bar across the terminals to a center buss bar
won't have to make up ten thousand cables.

Well, it is good to see you working on your truck again.  (June 2014-June 2017)

Those are some nice cells!

 :dD>:  Gonna start working on my truck again, picked up four Kia Optima battery packs.
Each pack has 9 batteries at 30 volts each 270V total.
So my packs: 4 batteries in series 120Volt  9 packs parallel.

Trying to decide BMS or No BMS

Hello everyone,

Is there any information on the AC50's motor parameters? I've been seraching them up but, so far, I've been unsuccesful. I need the stator and rotor resistances, as well as their inductances, or at least, a fair estimate of their values. Does anyone have measured paramaterers this already? Any help would be greatly appreciated!

Thanks,
Jorge

There is no rotor resistances  :Ah#: there is no winding in a ac motor, rotor.
The resistances in the stator winding is only 2-3 ohms, the lower the voltage
the lower the resistances. For instance, what is the resistance of 60 foot piece
of 18 gauge copper wire, that is roughly the length of one coil set, one phase.

Make sense ??

mizlplix SUCCESS!   Tanks alot man, you saved me a lot of money! :mE>: :uy<:
Bought simple RS232 socket at radio market for 0,5 dollars and it works! :EL^:
Thanks again!

most computer PSU's are 12VDC (yellow wires) or 5VDC .

That 5VDC is what lets most single lithium cells recharge. (3.5VDC).

The 12VDC is what runs the accessories, fans, hard disc's, DVD burners.....

That TTL converter was just an experiment because several persons insisted it was needed.
It is not.

ALL computer ports are 5Volts  NOT 9volt
So I was misinformed. That's strange. I used to trust that guy. He is pro.
