HCH2 - IMA battery reconditioning

Re: HCH2 - IMA battery reconditioning
I have finished 3 charge cycles.
below I present notes
1 cycle
charge time 25h
peak voltage 186 V
time to 158 V - 7h 50 min.
158V - 106V - 4h 25 min.
TOTAL DISCHARGE TIME 12h 15 min
2 cycle
charge time 25h
peak voltage 188 V
time to 158 V - 11h 30-40 min
158V - 106V - 2h 40 min
TOTAL DISCHARGE TIME 14h 20 min
3 cycle
charge time 24h
peak voltage 189,8 V
time to 158 V - 12h 40 min
158V - 106V - UNKNOWN (I finished discharge at 80 volts)
TOTAL DISCHARGE TIME ~ 15h 20 min
are these good results?
Should I make another cycle?

Big increase in 2nd
Small increase in 3rd
Each charge went a little higher.
That's exactly how you want it to go.
You can do a 4th, but it's unlikely you'll see any significant gains. Assuming ~355mA current during discharge, that's 4500mAh capacity on a 5500mAh pack.
I'd say you're done. Charge and go.

Re: HCH2 - IMA battery reconditioning
Hello, I have a 2007 Honda Civic European and I would like to try Building a HCHII grid charger but I needed the construction scheme, step by step.
Please help me with the scheme.
Thank you and sorry for my English

Re: HCH2 - IMA battery reconditioning
As rightly pointed out by S Keith, the schematic applied to a previous generation, can't recall what forum I found it on.
The following depicts the one I built, as you can see I can't draw to save my life

Hi Coval,
thank you very much for your help and quick response. I liked to build my own network charger,
but I wanted a step by step diagram and if possible with pictures of a grid charger / unloader, without always having to remove the battery from the IMA.
Thank you in advance

Re: HCH2 - IMA battery reconditioning
The HCH2 requires a PWM controller to properly drive the in-car fan, or you can short the PWM cable to ground and drive the fan with a 12V/10A power supply (it's powerful like a leaf blower). Coval installed a simple 12V 80 or 90mm fan in the exit duct blowing into the trunk (thus it sucks air through the battery from the interior). In my case in, this was not sufficient except in the coolest months.
