I always said I won't install an active balancer on my battery, so this is just a test, right?! It's a test! 😊This morning, the battery was at 12%SoC and very out of balance and I was wondering what would happen if we install the active balancer from Hankzor. Can it balance out these high capacity cells and save the battery from been disconnected by the BMS?
It's a test, right?

@camro210 3 года назад

In theory, it actually makes sense that the pack voltage increased after active balancing (in your specific situation) because for a given amount of amperage transferred, the higher voltage cell would see a *smaller* voltage decrease compared to the voltage increase that the lower voltage cell would see. This is due to where each of those cells lie on the voltage curve, of course. In reality, that would obviously depend on how efficient the balancer is.

I’ve assembled a 4 cells battery with BMS only and I had a troublesome cell, it charges faster than the other 3 so the pack never could charge beyond 3.35v each cell. Until I added a 5A HELTECH active balancer and I was so happy to charge the cells to 3.65v each. Definitely the active balancer made a big difference in my case. It balances the cells at all times while the BMS balances the cells only when charging (not sure about when discharging) and with a small 200mv dissipation from the overcharged battery. The active balancer does not dissipate the over amps, it rather transfer the amps to the other cells with lower charge.

@Jasonoid 3 года назад

@rickcooperjr62864 3 года назад

Glad you see the light a active cell balancer removes a ton of headache / hassle as I suggested several times its the way to go for simplicity and theyre power draw is almost a mute point the thing is it protects your cells from imbalance of cells dipping to low while others are in the good this can and will prolong the lifespan and use ability of your lithium cells its a win win for literally pennies compared to the rest of the hardware and such so where is the negative there is only positive in installing / using a active cell balancer.

Great vid on using a balancer. It can help squeeze a little bit more out of a pack as it's getting low. A balancer really is cheap piece of mind, plus long-term it might just get more life out of a cell that might have failed sooner. That's a hard thing to test since each cell is unique, but I'd bet it really helps out in the long run. I think a long-term test like 6 months or so and then remove it and check for deviation after a week of no balancer to see if the pre-balancer deviation has returned. That should show if it's doing anything for life extension or not.

@OffGridGarageAustralia 3 года назад

Now after several days, all cells are still in balance. Once this has been achieved, I think the max 5A balance current is fine. As the balancer works 24/7 it does not need to be as fast. As seen in the video, it takes only 12h or so to get them all in line again.

The bottom "Knee" curve is not linear - the lower the voltage the less energy is needed to proportionally impact the voltage overall voltage increased because your moving energy from a fatter part of the curve where substantial energy is needed to impact on voltage to the thinner more sensitive zone- you are bottom balancing your cells which is probably better for your pack as you have capped the upper voltage at 3.45v preventing it climbing the upper knee much to effectively upper balance accurately

@edwingroen2028 3 года назад

My active balancer is connected parallel to the Daly 200A smart BMS and it works fine since the start. Bms is burning high voltage off and wasted as heat. The active balancer is always on and will continue to balance between full and empty cells. I like it so much that I will do the same next time again. You get more amps in and out of same battery pack.

@off-grid-garage Andy, now for a test on overall capacity acheived w/o balancer (until BMS cutoff) Vs. W/cell balancer. In theory you should be able to get more energy out as the higher capacity cells should feed the weaker ones so they all hit cutoff at about same time.

In a low current (solar, not vehicle) situation, i always suggest inductor balancers instead of capacitor ones. The reason is, that you always need to convert energy between magnetic and electric fields, to achieve low losses. But of course a capacititor model does the job and delivers current. Most of the time we store energy in a static voltage field, what means that a low loss energy transciever needs an inductor and a switch. Its a smps then. If we would use a rotation storage, inductive coupled to an also alternating voltage, then an good energy transformer would make use of capacitive energy delivery. Imho we all would throw away much less lithium batteries, if there would be active balancers in them and not only balancers which start to balance, when a cell is already in a harm region. Had a fresh battery for my scooter, which was weak aftr only 2 years. I opened the thing and the 24s lifepo was absolutely out of balance. I figured out, the top balance was not sufficient to hold the chargers amps. After adding an active balancer, i got it back to work since half a year. You do a great job there!

@muddy11111 3 года назад

On your recommendation I got a QUCC BMS. However I got the mosfet one not the relay. On overcharge of a cell this simply turns off the charging, leaving the discharge and balancing functions still working. You also sold me on the balancer. That works OK, but to stop high cell voltage cut off I run the BMS balancer at 50mV below cut off voltage. This just keeps the balancer out of trouble. Cells are balanced nicely over most of the curve, but getting the top end balanced looks like taking several days. Heading in the right direction slowly. Keep up the good work....

In my first test I charged the cells to 3.45V with a cell difference of greater than 100mV. The DALY BMS switched off charging at 3.5V for the highest cell and the internal balancer apparently had no effect. Then I connected the active balancer and you could watch the voltage difference decrease. It took less than 12 hours for the cells to balance at 3.45V with a voltage difference of 1mV. I was just as amazed as you.

Hi Andy, Good day, Just want to say that I was expecting that you going to change you mind about the active balancer. It is lucky that you got the right one and not the small one which might have change the outcome and your conclusion of this test as well. Looking forward for the second part of the test at the topo f the voltage and I do expect the almost the same result especially after a few hours after the sunset. it will equalize. Just probably if you wanna test further on the active balancer , i suggest it would be: 1) The balancer will keep balance the cell even all the cell are balanced. 2) if the above true, that mean the balancer will drain current overtime especially with smaller capacity pack. I had a friend who installed this balancer for the 32650 4S 12V and leave it for few days, the pack drain to 2.++V.

@lukasmauerhoff9330 3 года назад

I see a disadvantage especially in your case with a relay-bms and slightly missmatched cells. If you're battery is at a high state of charge and there is a high amperage outside, overvoltage disconnected will trigger because the balancer destroyed your top balance and will not be able to keep up with the sun. Because you have a relay-bms, there will bee no consistent power anymore until the sun is down and the balancer is finished. You maybe get that alternating on/off situation again...

@OffGridGarageAustralia 3 года назад

I don't think this is going to happen. My max charge voltage is only 3.4V and then I let the battery absorb, so current will taper off. So far the 'balancer test' seems to work quite well but I have to wait what happens when I fully charge the battery again.

@@OffGridGarageAustralia I can feel it coming closer, suddenly no more worries, just a max capacity scenario for your cells that actually partly solves the "more wear on weakest" issue by offloading load to stronger all the time and perhaps long term levelling the performance, too. You know it's good, proven in multiple vids, don't string it out any further, just install them for good and put a disable switch on it for your sanity/fear if you must.

@mccyrille 3 года назад

With your raspberry, maybe you could turn on your active balancer with a relay (there is a pad "run" weldded on the active balancer) only when you are in the top or the bottom of your SOC ? It will correct the little deviation every day, but when you're on the flat curve, it doesn't work and don't transfert power between cells.

@OffGridGarageAustralia 3 года назад

The balancer runs 24/7 now for the test. If it does not balance in the flat part anyway, why should I make the effort and turning it off? The standby current is only a few mA, far less than for the Pi. Who would give the signal to start the balancer?

@mccyrille 3 года назад

Pack voltage is going up because you're putting energy into cells that are deep into the knee, while the energy is coming from cells that are not deeply in the knee.

Hi Andy, and greetings from Tweed Heads. I only just found your videos, as I am currently making an off grid system using EV batteries, so have been researching. Love your videos and the sense of humour that goes with them. Just a quick question in regard to the Active Balancer. Did you connect this along with the BMS? I can't see in your video if you disconnected the BMS to attach the Balancer or whether you are running them together. Thanks Regards Dean

@OffGridGarageAustralia 2 года назад

Hello Dean from Tweed Heads. The balancer is just an addition to the BMS. It boosts the balance performance but won't protect the battery. So you always need a BMS for that purpose.

@mendo3427 3 года назад

Hi andy. I virtually have the same set-up as you. The main problem i am having is the solar power. When full sun is out i am pumping over 75amps into batteries. This then raises voltage very fast to and over the 52v , which inturn overloads the batteries and shuts off relay. This then upsets the victron MultiPlus-II and shuts down, loss of power

@OffGridGarageAustralia 3 года назад

52V is far to low. Not sure about your settings but this is only 3.25V/cell. This could mean you're cells are only 30% charged when they reach this voltage. Try to set 55V or 56V in your solar charge controller. That would be 3.45V-3.5V/cell. That should work a lot better.

@mendo3427 3 года назад

@@OffGridGarageAustralia thank for your reply andy I should have explained in better detail. 55.1v is my victron bulk/Absorption charge setting not 52v. When solar is pumping 75a into batteries voltage increases, on some cells it brings them to 3.6v and then over which triggers the quacc over load as it should as protection, this then cuts power, and MultiPlus-II doesn't like it, gets confused and shuts off inverter to which then has to be manually restarted.... pain

@frankammerman3296 3 года назад

Worked on F-4 Phantom avionic systems 1970 - 1974 USAF. Electrics were connected with Amphenol connectors. Looks like to me you could wire up your battery bank with a female multi pin connector and use a male matching connector to connect your BMS. If you wanted to have testing equipment connect to the bank they could be already wired ready to use. Would make it easy to change leads rather than reconnecting terminal rings on each cell every time you wanted to test or rig up something new or different. A strip of banana plugs would also work. Easy to check with a multimeter. Amphenol pins might be close to close together to be checking with multimeter. What do you think?

@OffGridGarageAustralia 3 года назад

Well, that could be a solution. What my intension is though, I would like to NOT play around with the big batteries which are in production at some stage and rather have some test cells sitting on the workbench to do testing. Once testing is confirmed I may do these changes to the big batteries. The final battery won't have anything connected to the terminals any more as the balance leads for BMS and balancer will be connected to the busbar directly (M6 tap).

Andy, the total voltage of a battery pack can rise with an active balancer for the following reason. The voltage of a battery cell is non linear, especially when the battery is near empty or near full. Let us take an extreme example of a 2S battery pack. cell 1 : 2,5V cell 2 : 3,2V Total = 5,7V When the active balancer transfers capacity from cell 2 to cell 1, the voltage of cell 2 will decrease less then the increase of voltage of cell 1 due to the non linear behavior of a LiFePo4 battery cell. after some balancing time one could have following measurments cell 1 : 2,7V cell 2 : 3,1V Total : 5,8V I hope to have cleared out the origin of a voltage rise when balancing with an active balancer at low SOC or high SOC. Greetings, Luc from Belgium (near Austria an far away from Australia)

@OffGridGarageAustralia 2 года назад

Thank you. Yeah, that makes sense. Hence it is important to always have a BMS as well which monitors single cell voltages and disconnects the charger/load if one cell gets out of scope.

@tiloalo 2 года назад

Voltage increase because voltage is not proportional to charge in lifepo4. So the battery that were good didn't loose as much voltage as the battery that were charged gained.

@rcinfla9017 3 года назад

I am an advocate of active balancers. Cheap ones can have issue with proper balancing direction when real world inverter and charger currents causes cell voltages to jump around confusing the balancer. Evaluating performance with no inverter or charging current variance is not real world use case. Be warned about capacitor charge pump type balancers long term reliabilility with electrolytic caps being subjected to high ripple current. Usually the cap's electrolyte dries out and capacitance declines. Sometimes they burst and short out from the high ripple current. As they are directly connected to cells (through MOSFET switches) there is no safeguard if they short out. If top of caps start to bulge out it is a warning of failures to come.

@OffGridGarageAustralia 3 года назад

I know about the problems with capacitors from my electronic background. I think they have used the better quality ones which are fully sealed and don't dry up any more as other types do.

@stuartsmith945 3 года назад

It is not unreasonable that the voltage went up with the balancer running. Cell 6 was in the steep part of it's charge curve where most of the other cells were in a clatter portion. The balancer will affect the voltage of the higher charged cells much less than cell 6 so cell 6 increases in voltage more than the sum of the higher cells decrease in voltage.

Yes, I figured that later on after reading many comments here about it. It was not obvious when I looked at it at when recording.

Can you not adjust the love voltage disconnect in your inverter? 14.3V is far to high. It should be around 11V for a 4s LFP pack (2.7V/cell).
