    Be careful when adding batteries to this balancer. Ensure the modules being inserted into the group have a voltage close to the other batteries on the balancer. Otherwise a lot of amps may flow very quickly into/out of the battery being added to the group. You can use a SkyRC charger to charge the group of balanced batteries @ 5.2 amps total, however I recommend charging the modules one module at a time. The reason is each module has different capacities and resistance. When I charged the whole pack up to 8.30 volts, when I discharged some of the modules, their mAh capacity dropped considerably. I used to think it was the electrical connection of the aluminum strips on the balancer. But even when I connected the modules with copper wire using nuts, I had similar strange results. When I charge just two modules together in parallel, the discharge capacity is lower than expected. I think this is because the charge being applied is too low, and somehow the batteries with more capacity will take on more of the charge, and the modules with more resistance will be charged less. I have found that if you want strong discharge amps, you need to charge an individual module with 3.0 amps or 3.2 amps. If you charge the modules when connected in parallel, the charge amps are much lower (per module). When you discharge the modules to test them, some of them will have much fewer mAh than before. I also decided to track the temperature as the modules are being charged. If you have a charger similar to the SkyRC charger, you can buy a temperature probe for about $10. I would cut off the charger at around 82 F. In the summer, you obviously will have a different cut-off temp. I noticed my Prius pack can sometimes get up to 125 F (at a time when the pack was not paired up properly). When pairing modules up for the pack, it is important to pair them up, first on resistance, and then mAh capacity. Do NOT pair weak modules with strong modules (formula for pack failure).
    I noticed that when charging a module @ 3.0 amps up to 8.60v, the module got warm (about 82 F) and the module expanded. After doing this, the total capacity went up to about 3000 mAh, and it took a charge of 3236 mAh. Keep in mind the modules I tested were old and were the best of the modules that did not make the cut when I rebuilt my hybrid pack. Over time, I came to the conclusion that charging @ 3.0 amps is safer than 3.2 amps. However, I have found it beneficial to charge a module a few times @ 3.2 amps up to 8.60v to get the module to get it discharge more normally. After a few cycles charging @ 3.2 amps, I will switch back to charging @ 3.0 amps. I tried clamping two boards around the module to prevent it from expanding. This helped reduce the swelling, however this causes the module to get warmer more quickly, so I like charging a single module with a fan on it, and turn off the charging when the temp gets to 82 F. I noticed the module starts getting warm at 8.500v (80 F), gets warmer when the voltage is at 8.550 volts (81 F), and gets warmer when at 8.59v (82 F) (each module will be different and hopefully this improves with each cycle). Note: the voltage I am referring to is the actual module voltage, that my custom Arduino code captures for the one second (every 30 seconds) which is when the SkyRC charger is not charging. The SkyRC charger thinks the voltage is more like 8.70 volts, but when it stops charging, the voltage is closer to 8.59 volts. Note: the max voltage a Prius module can store is about 8.60 volts, and Delta V is triggered at around 8.72 volts (if it gets triggered). The SkyRC charger usually does NOT detect Delta V (which occurs when a module is fully charged).

      Great. Dr Prius shows my state of health at 95%. I don't know the history of the car, since I just bought it, its 2014 Camry with 190k miles, so my guess that the battery has already been serviced or replaced. My question is can I use a mechanic balancer on all modules for 48 hours with out using any kind of charger, and will just balancing the modules along be a good source to prolong the battery life? Thank you 👍

      I would also like to know if I can rebalance the battery without connecting it to a charger. Is the charger just to insure that the modules are all at max charge before I start rebalancing?

    • @GaryMarkowski
      @GaryMarkowski 10 місяців тому +1

      Yes, you can balance a group of modules without a charger. At 11:00 in the video, Jose has two modules connected in parallel (hanging from the aluminum bars). When connected like this, electricity will flow between the modules, and their voltage will become equal (balanced between the hanging modules), without using a charger. When you are inserting another module into the group of modules being balanced, you should check the voltage of the module. If it is less than the group voltage, then I would charge that individual module up to the voltage of the group, before adding it to the group. If the module is at a higher voltage, then I would connect a charger to the module, and discharge it down to match the voltage of the group of modules. However, each of the 28 modules in a Gen 2 Prius contains six cells. The six cells will get balanced (somewhat) when you charge the modules up to 8.40 volts (Jose explains this in another video where he describes the six cells being balanced in a module). Once the modules in the group are at 8.40 volts, you can apply a small trickle charge of 0.5 amps for the pack (or 0.1 amps for a module) @ 8.40 volts for an hour or so (I do not know how long is safe to trickle charge at such a high voltage of 8.40 volts). DO NOT CHARGE HIGHER THAN 8.40 volts!!! If you charge a module @ 8.70 volts for a few hours, there is a good likelihood you will damage that module! The module has a safety feature that kicks in around 8.70 volts causing the voltage to drop suddenly, which indicates the battery is fully charged, and that you should stop charging it. Most chargers do NOT detect this voltage drop. If you charge higher than 8.5 volts, it may use up the chemical that triggers this voltage drop (which is what I mean when I say you may damage the battery). The Prius charging system can detect this, but if you use up the chemical that triggers the voltage drop, then the Prius may charge the battery pack higher than intended. Note: I charged some of my modules higher than 8.70 volts, and I suspect that I damaged them, which would explain why my Prius sometimes charges the modules up to 9.5 volts (when driving). The Dr. Prius app lets you see (and record) the voltages when driving.

      @@GaryMarkowski So you can rebalance batteries without a charger but I still need a charger to be able to charge or discharge modules to even out voltages before balancing. So a charger is still needed. What kind of options are there for a charger? A prolong charger is a little bit too expensive for myself. I have noticed some people use an rc charger of sorts, and I understand that a low current charger is what I need. But what are my options? Is there a video or website that could help me make the decision on what kind of charger I need and can afford?

      @@YaroGoret I have two SkyRc V2 RC chargers (no fan). They work good, but they do NOT detect when the battery is fully charged (this is a huge problem). So if you buy a RC charger, make sure it works with NiMH batteries AND will automatically stop when the battery if fully charged. I have seen some videos where they charged a single module @ 10 amps. This is huge no no. I have charged some modules @ 5 amps, and some of my modules failed after doing that. I think you can get good results charging @ 3 amps (or 2 amps). You may need to charge at least 2 amps (per module) to reduce the "memory" effect that can occur at lower charge rates. There is very little information out there to tell you exactly how to charge your modules, so it is a big learning experience (trial and error). The Prolong charger used to cost around $450. The nice thing about it is you don't have to learn much, and it will take a LOT less time to charge/discharge the whole pack (effort wise). I would not discharge a single module any faster than 2.5 to 3 amps (one auto headlight). I spent about 120 hours researching this topic. You can save research time by buying the Prolong charger. Maybe other people can share more recent information regarding chargers. 20/20 hindsight, make sure the charger you get can auto detect when the battery is fully charged (which will be around 8.40 volts (or less)). When a module is fully charged, the voltage will drop suddenly (ie. Negative Drop in Voltage - NVD). I find most modules do not take and keep a charge above 8.20 volts. If I charge these modules up to about 8.25 volts (individually), this seems to extend their capacity when testing their discharge. Once charged, some modules will drift down to 8.08 volts, and most will drift down to 7.88 volts. The ones that hold at 8.08 volts usually drop below 8.0 volts within 10 seconds of a headlight being attached.

    The weak module still stays weak. What you get when you combine them in parallel is the total voltage of the two cell modules in parallel. Same as the ordinary flashlight cells, if the flashlight has two week cells and you replaced only one of them with new, it will have a higher total voltage but the old unreplaced cell will remain weak.

    I got my very out-of-balance modules close (less than delta .2v) by individually charging them using the Dr. Prius app in real time, charging the weakest block's modules seriatim. But finally I decided to just wire them all in parallel. I didn't feel like taking the frame apart (again), so I made up a harness with 14 red and 14 black connectors to slip over the respective pos/neg terminals on the input/output side of the assembled battery. I took off the copper plates on that side and installed the harness. This gave me 14 batteries wired in parallel (I'd already matched the modules to be very close in voltage at rest). I then connected the harness to a Tenergy charger that can charge from 3 to 18 volts, and programmed it to do three charge/discharge cycles at .5amps. My harness does the same work as Jose's aluminum balancing beams but with the additional advantage of being able to do a bit of reconditioning and charging. (And it takes up a lot less space!)

    Is it possible to trickel charge the cell while they are in parallel on the mechanical cumustomised aluminum balancer device you made? In theory, can you start with balancing all the cells. Once they are all balanced, slowly charge the cells by hooking the charger up on the aluminum rack and slowly charge the cells up. Wouldn't this reduce heat "loss" and the cells would charge more quickly? When the charging is done, then just disconnect the charger and let the balancer rest a few days. Done! Thoughts?

    Do you mean toyota have not installed an active BMS for these batteries? This means their quality is fenomenal and incredibiloid!!!. I have an RX400h with the original battery for almost 15 yrs. Incredible.

    Hello, my very simple principal question. Why is such a big deal balancing the modules so closely!? I understand if there's a big difference but what if they are about 0.5 volt different? The other thing is do you load test them before balancing them. How about if they have different capacities under the load even if they have almost the same voltage!? Thanks

    I already replace the bad battery cell and measured every battery cell and there all around 7.76 and 2 cells are 7.80. Would you recommend balancing them again and doing the process of discharging and charging them back up

    I was curious if balancing the modules actually improved the modules, so I explored balancing the pack more, and I have a theory of what happens when you balance the modules. After balancing the modules, I charged them individually @ 3 amps up to 8.50 volts, and then tested their discharge time. For some of the modules, their capacity dropped dramatically (to 20% of their previous capacity). However, after cycle charging/discharging them a few times, the capacity came back. What is going on here? I think what may be happening is that when you balance the modules, the electrons flow back and forth much more, causing clumps of material to become dislodged. I think this back and forth action is similar to how water in a swimming pool moves back and forth when someone jumps in the water. I find some older modules have a hare time keeping the voltage at 8.20 volts. A module that cannot be charged higher than 7.2 volts likely has a bad cell, and should be discarded. Charging a balanced pack up to 8.40 volts for 12 hours likely is safe. Doing this step will likely bring the voltage of all 6 cells in each modules up to 1.4 volts each (8.40 volts / 6 cells). Balancing the modules this way is dangerous so BE CAREFUL! Make sure + to + ALWAYS, and also make sure a module's voltage is close to the pack when adding it to the balanced pack.

  • @amazoidal

    Just took out a 2007 battery that was "reconditioned, balanced" 3 months ago by a "Prius Battery Specialist". It was failing because balancing is a waste if the Internal Resistance is high on the modules. I picked the lowest IR batteries from my 3 packs and the car drives like new. Voltage is secondary. IR is the most important parameter for series-connected traction batteries.

      Only in the "Capacity" to transfer energy. High IR limits the cell transfer, no matter the capacity. One good test is a long hill. The hesitation or bucking that the car exhibits is high IR in at least one cell in a long series of 168 cells.

  • @earlbrosman
    @earlbrosman 2 роки тому +4

    This method does charge each battery to same voltage. But, if any cell has less capacity (volume of current capacity) when cells are place in series (as they are in auto battery pack) they will fail to provide as much current as needed to keep up with other higher capacity cells in series battery. This method balances for same voltage but does not sort out cells with different storage capacity.

    • @hybridsolutiondiagnostics
      @hybridsolutiondiagnostics  2 роки тому +1

      Charging or discharging has nothing to do with the module's capacity... this is just to rebalance the complete battery pack to restore the overall battery pack's capacity the most it can be...

    Those aluminum bars is a very clever solution for voltage balancing.
    Having experience witth LiPo, LiFePo4, lead acid batteries and BMSes (battery management system) I know that same voltage doesn't mean that each cell has the same capacity (often cells are degenerated by heat).
    Cells in the middle of a battery pack get hotter, so best practice is to swap them with the cells on the outside. A thermal camera (very affordable these days) can give you insight about the temperature difference between cells and their condition (bad cells tend to get warmer, too).
    To recondition, 3 cycles of discharge and charge each cell (with approx. 0.6C - 0.8C and cooling) with 30min rest in between is pretty efficient. Could make a huge difference in capacity. For RC there are great chargers available that aren't expensive.
    NiMh doesn't like trickle (slow) charging.
