Prolong charger

The fuller the battery is at the start, the less work and time the charger has to do.

If you do not see the charge level fluctuate more than a volt or 2, the top end balance is done, then you can start the discharge cycle.

Some questions:

• What’s your plan (2 cycle discharge, just a top end balance, etc)?
• Did you have any dash warning lights before installing the Prolong equipment?
• Do you have the Intelligent Discharger or the light bulb Discharger?

Good luck and let us know if you have questions .

 

just did mine today as well and it's at 247 volts, after about 6 hours so I think it's probably in the balancing phase now. Their site says it can take 4-12 hours for balancing but I'm not sure if anything detrimental can happen if accidentally left on for too long.


edit: some good info here Update Part 2: Prolong Hybrid Charger /Discharger deluxe | PriusChat

 

The reasoning for leaving it sit at the voltage for a short period of time is to balance all the modules so when discharging, it affects all modules equally .

I follow the written directions from Hybrid Automotive .

As you have questions, post em up and we’ll help you through it.

Look forward to your data point.

Keep us posted .

 

Yes.

Charging to ensure the modules are balanced before deep discharge.

Some questions:

• Any reason you are doing a three cycle reconditioning?
• We’re you planning on doing the 84 volt then 17?
• Or doing them at the same voltage (134 or 84)?

Our 2010 with 175 k miles on it I have only done 2 cycle reconditioning (down to 84 volts) as we have not seen a dash light for a hv battery issue.

Good luck and keep us posted .

 

There does appear to be corrosion on the bars .

You said you think it is not the original pack. Do you see evidence of a repair, like different module manufacturers date, or other signs?

If it is a rebuilt pack, that changes my opinion slightly, but I helped a member rebuilt his pack in a 2006 and he just did a 2 cycle reconditioning down to 84 volts.

That’s one experience point, but looking forward to seeing your results once the process is finished .

 

Does this charger comes complete with discharged, or what? I'm trying to shop for one on Amazon? Can the charger be modified to work on all Toyota by rid and electric vehicles, considering I ha e lots of those vehicles I fix?

Thanks Ray!

Here’s their website:

Check it out.

There are several options that would work for what you do.

 

How long on average has it taken folks to recharge battery after 1st discharge at 134, I ask because mines beencharging for 13 hours and it's only up to 232.
Thanks

 

I leave it charging for about 19 hours before doing another discharge (around 24 hours for charge and discharge). The final charge will be around 24-30 hours

 

About 24 hours is about right.

Verify it is stable for 4-6 hours and then start discharging.

Good luck and keep us posted.

 

Can you just put the car in D and press the gas and brake and charge the car in 5 min to full maybe charge the battery after that the rest of the way

Yes if you're in a rush, that'll get it 80% full

 

Very interesting. I'm thinking if maybe getting a Prolong charger myself. One thing I don't understand is exactly how bottom balancing works or what it accomplishes. Is it simply discharging the entire battery to a set voltage or does it mean taking apart the battery and discharging individual modules or cells? Is there even a way to tap into the voltage of the individual cells?

 

It discharges the entire battery pack and removes the "memory" from the cells.

No need to mess with the individual modules .

The prolong equipment makes the process easy.

 

Oh ok! Kind of akin to NiCad?
