Bench testing a used Generation 1 Traction battery?

Use what you have. I was hoping for a regular 12V charger but use what you've got. Just take lab notes!

Resurrection of discharge NiMH Prius modules is very advanced. You are at the bleeding edge so take good notes.

BTW, there is no guarantee of success but not trying guarantees failure.

Do you have a motorcycle mode on your charger? Once a month I charge my spares on my C-tek 3300 at motorcycle mode and it will stay below 9 volts over night and no over heating from the cells. I like my C-tek because it has a maintenance cycle to help de-sulfate the battery.

With the charger on the way you can do them in stacks safely. Just keep an eye on the temperature.

 

Ah poop, okay, well you got the Reaktor on it's way so you are headed in the right path. That is awesome news about the seller of the donor.

Very unusual these days.

Just please be safe and use common sense Brother. High Voltage is not your friend :-(

 

A 12V automotive charger is not going to match what your Reaktor might do. Which model Reaktor?

The reason I ask is the User's Manual may be online and give us insights to how to use it most effectively. Don't spend money on a 12V auto charger until we understand what you've got.

It will be important to use the temperature probe when charging the NiMH modules as they have a rapid temperature climb when full. To recover modules, you'll need to set a time and temperature limit for each module.

Some chargers have the dV/dt sensor and can detect the voltage drop just before the temperature rises. My experience is our 6-cell, NiMH modules do it right, the first time. But subsequent cycles have to be 'charge limited.'

Good choice and much better than an automotive grade charger.

Hi everybody,
I just renovated a HV battery from prius1,
I used a charger / discharger NIMH for 2 to 10 elements 1.2Volts
I reloaded them one by one in steps of 0.3Volts from 7.7Volts initial to 8.3volts final
Voltage after 24 hours = 8,10 Volts smoothed on the 38 elements, load = +/- 60%?

The vehicle rolls today without any problem
but I would like to use an application to monitor its functioning,
if I can be useful in your approach to decrypt the info of the Prius1

 

Merci
Depuis, une application a été développée : Dr. Prius compatible pour les Prius gen1
Téléchargeable par APKPure , version gratuite permet de visualiser chaque élément en temps réel
Tension de chaque élément (vert) avec sa résistance interne (bleu), Tensions globales, état de charge, Températures ...



Un OBD2 Scantool LX est conseillé pour suivre le débit rapide des infos.
Ici, on voit la paire d'éléments 4 plus faible dans le barographe des 19 paires d'éléments
On lit un delta de 1,30Volts dans l'énoncé des infos : donc élément faible

Cette application est compatible également avec les Prius Gen2 et d'autres modèles plus récents


Un Zoom du barographe vert est fait sur la plage maxi des tension

IL existe plein d'autres applications également dont Hybrid Assistant mais non compatible Prius gen 1
