I think a tail current is still of critical importance. The caveat should be that it should be used in conjunction with the desired voltage. For example if full Charge voltage Is set to 56.64V and the tail current is reached at that voltage, the BMS should consider the battery to be 100% charged. If the prevailing current is equal to the tail current but the voltage is below the set voltage of 56.64V the BMS should consider the battery to be below 100% charge. Charging should be allowed to continue until both the tail current and the desired voltage are reached.
@MMMM2MMMM2MMMM

What will this do when the battery is older and the capacity dropped to 80%. People who have bought battery's might not buy/build another anymore. Just curious what a tail current is.
@garymeissner6659
10 ай бұрын
I have to agree with Andy on this one. If you are charging at a fixed current, then "tail current" works very well. But in our PV Solar setups, the charge current is typically much lower than the C rate of the cells, and it varies all over the place. Once the voltage does finally reach the absorb voltage, the charge controller should just try to keep it there. But as the sun goes down and clouds go by, the current can still dip off, but then come right back, even if the absorb voltage has ben reached. We should still hold the voltage at the bulk absorb voltage for the desired time, even if the current falls lower from time to time. On the flip side, when I use my mains charger to charge up my e-bike batteries at the 1C rate, the tail current is a very good indication that it has reached full charge. My solar battery bank only charges at 0.2C which is not much over the typical tail current for the cells. Different use case will change which works better.

6:40 ... Yes grouping is best, especially from an accessibility perspective. It would be nice if the settings for the precision is the same for all values too. Makes it easier to read. SOC to 100% .. what if you have one cell that is higher then the others and hit's this limit before the balancer can bring it down? Is it instantaneous, or is there a delay? On the zero volt state of charge ... is this linear, so it doesn't show 10% then suddenly 0%? The naming of some of the parameters is confusing. Would be nice to have an icon for a bigger description ... RCV is float voltage? Dry trigger ... turn on fans . That's great 👍 23:00 ... On the ability to turn float off and on, is there an API that you can call to run a job to automate this? Cutting edge is cool, but I'll wait for now👍 As always awesome stuff !
@OffGridGarageAustralia
10 ай бұрын
Thanks for your feedback. The 100%SOC is not perfect. If on cell triggers it, it will not interrupt the absorption and balance time. It just sets SOC to 100% and remaining capacity the same as battery capacity. Voltage is not linear with LiFePO4 but SOC will not jump as the BMS uses coulomb count to count down SOC. SOC0% and SOC100% just shows the BMS where the boundaries are. No API, except the BT connection you can potentially tap in. Not sure if this is possible.

The quality work you do keeps us coming back and keeps new subs coming to the channel. You do so much for the community and we all appreciate you very much. I'm really happy to see that JK has been putting in the effort to make their new BMS feature competitive and correcting its many wrongs. I hope that this entire experience has been a valuable lesson for JK....don't release a product until it is ready. They've lost some credibility by releasing this product too early, and even more credibility lost by advertising support for over 40 inverters when they support way less. Never a good idea to get into the practice of false advertising. It's very difficult to develop and keep a good reputation and very easy to develop and keep a bad one. So please JK, let this be the last time you pull a stunt like this. Having said all of that JK, you still have a loyal following of customers who are rooting for your success, so keep pushing, keep innovating.

My Charging (absorption) voltage is about 54,7V with high current for an hour, and then raises to about 56,7V with low current. Thats the wrong way in voltage!?? Cerbo is set to DVCC Mode. My most important BMS settings are: Cell OVP: 3.65 V Vol. Cell RCV: 3.6 V = 57.6 V SOC 100% Volt: 3.55 V = 56.8 V Cell OVPR: 3.54 V Cell UVPR: 3.02 V SOC 0% Volt: 3.0 V = 48 V Cell UVP: 2.8 V Power off vol: 2.65 V Vol. Cell RFV: 3.50 V = 56 V RCV time: 1.0 H RFV time: 6.0 H Someone can help me to get this right?

Hello Andy, It seems promising but we have couple of things that needs to be tested For example what if while in bulk charge mode we didnt have sun energy as it should for one hour, in that case it will turn to float mode without actually giving the batteries enough time to absorb, and if we increase the time then we are putting the cells under pressure of absorption more than it should
@OffGridGarageAustralia

Well, if you haven't got enough sun to stay at the absorption voltage, there is nothing you can to regardless what settings, functions or features you have. The voltage will go down in any way. if you hit absorption voltage, you will be at 99% anyway, so... 🤷♂️ Outcome: there will be no absorption for that day. No drama, it will do it again the next day or in 5 months after winter...

Hi Andy. Myself I would like the re-bulk to be triggered by cell voltage, rather than a timer. It would seem that by timer the battery could be topped up many times during the day even if no significant load has drawn any Ah out of the battery. Needless charge cycles on the battery? By using re-bulk by cell voltage, a small load would not trigger a re-bulk, but a larger load that draws the cell voltages down enough would usefully refresh the battery. Im fully off grid and the Victron mppt's do this perfectly. The Victron inverter chargers not so much given you cant select the actual re-bulk voltage. A note about the buzzer warning and dry contact relay use would be that it looks like you can only select 1 parameter option?? Maybe a tick box for each parameter that you would like to select.

The idea of the timer is to NOT have it topped up again the same day (timer runs out at night). With LiFePO4 it makes little sense to top up again. There is no real difference in capacity gain to go from float back to bulk voltage. Less than 0.5% usually. So a repeated top up during the day has almost no effect and only stresses the battery. You have two relays which can be programmed individually. I think it's a great feature.

The wire resistance is a bit more important in the JK BMS. Since the balancer can pull or push 2 amps to any cell, that resistance is used to correct the cell voltage reading. My JK-BMS calculated from 0.131 to 0.142 ohms for each lead. At 2 amps, 0.142 ohms will have a voltage drop of 0.284 volts when the balancer is operating. If it is trying to measure the cell voltage while the balancer is operating, it knows to calculate this voltage offset to add or subtract it from the measured voltage at the balance wires. If a cell is being discharged, it needs to add this offset back. And while the balancer is charging a cell at 2 amps, it would then need to subtract this raised voltage from the cell measurement. When you change the pack parameters, it appears to measure the resistance all by itself. It pulls and pushes balance current from each cell and measures how much the voltage changes and then calculates and stores that as the resistance value. In reality, this resistance is 2 complete wires for each cell. Cell one is the resistance of the zero wire on the negative main terminal AND the 1+ wire from between cells 1 and 2. Any voltage drop on both wires all will add or subtract from the cell voltage reading of cell 1. Cell 2 also uses the 1+ wire, but then has to add the 2+ wire to that. My wire 2+ is the pin that failed in my JK-BMS. When that lead failed, it showed both cell 2 and cell 3 as zero volts. On BMS units that only pull 0.06 amps for balancing, this is not a big deal. But at 2 amps, it certainly is.

The BMS does not measure the voltage during balancing. It waits for a few second after balancing to have the cell voltage stabilised before measuring and making a decision again.

I think a tail current makes absolute sense in combination with the voltage like the smartshunt does. If ther is a cloud then not only the current but also the voltage drops but this value is also a requirement for 100%. A time doesnt know anything: if the voltage is reached in a sun peak, it's likely that a few percent are missing.

Hi Andy, thanks for making such an informative and entertaining channel! Your videos have led the way for me to put a DIY solar storage battery system in place with confidence. Your last videos on the Peter CAN interface and the JK inverter BMS have raised a question for me and your thoughts would be appreciated. Im in wet, windy East of England, 600mA outside! My question is do I really need BMS communication to the inverter. What are the real advantages and if multiple BMS managed batteries are in parallel is it valid to use just one smart BMS to communicate with the inverter. I have 7 batteries in parallel each with its own BMS and 3.6kW of solar with its own inverter. The parallel battery array charges and discharges between 49.5V and 55.2V under control of the inverter. The inverter ensures there is zero import or export at the mains input by monitoring with a current transformer. Once the batteries are empty the house just runs from mains and the backup power function is not used. More detail on the exact battery arrangement - I have seven batteries derived from reusing customer returned SolaX TriplePower 115V units, these are rewired to six 16S 2.6Kw batteries with JK 100A 1A BMS’s and there is one GivEnergy 8.3kW 16S also with a JK 150A 2A BMS. All of the batteries are LiFePO4 and had OEM BMS faults but the cells are good. Each battery runs through a JK BMS and each positive line has an 80A Eaton EV fuse. The Solax boxes now house two 2.6kW batteries and they are paralleled after the fuses. The four battery outputs then run through their own 80A Tomzn DC MCB and are then paralleled to form the output to the inverter with a Victron smart shunt in circuit. The inverter is set to draw a maximum of 50A of a potential 60A and charge at 35A of a potential 60A, it is a Sofar ME3000SP. The inverter is running in lead acid mode, the CV charge is 55.2 and the low voltage stop is 49.5V. The inverter will charge the batteries overnight when I have low rate mains power. It seems happy to bounce around between these two voltage values and if the battery has been charged from the solar during the day I can see the batteries change from 35A CC to CV and the current tails off so they are 100% SoC. Current is shared between the batteries as you demonstrated in your videos and each battery has protection from a fuse and the BMS so cell shorts in any parallel battery should be controlled and each BMS has settings for the connected battery so excess primary output current should result in a cascade shut down of all of the batteries and avoid having the 2.6kWh batteries delivering too much current if the larger one has disconnected, the larger battery can provide the full 50A so there could be a case of the large battery becoming discharged. The BMS settings overall should limit any inter battery currents to 45A.

You definitely don't need communication. As you may know, I have my battery shelf setup without any comms and it works flawlessly. On the other hand: If you have 7 banks in parallel and one BMS trips out due to a protection triggered by the BMS, you would not even know. But maybe you should, so you can attend the problem before it may get worse. So communication makes a lot of sense from a safety and monitoring perspective... I'm only exploring other options to see what benefit or pitfalls they bring to the table.

off topic: are you planning a video about the degredation of your batteries now that they are getting older ? I do not have a clue how many cycles you run a day but if then you could be at the 1000 cycles point considering that you started 3,5 years ago or so with the LFP battery cells. Do you have recogniced in your oldest battery any degredation so far as you ar not the compression guy ? We have seen here a block which was fully charged and top balanced before that had been forgotten. And then weeks later memory kicked in that there was another battery waiting to be mounted . Meanwhile the cells had not been used and they got a belly of 1 mm on each side, so about 2 mm in total between 2 cells as they were not fixed when they had been charged. The 30 day voltage drop measurement was the last step that had been done, before they had been forgotten. Now they are bulky but we can not see any difference in capacity. All cells had beene tested before individually 3 times so we have a clear picture of before and after.

Andy, I am pleased that you are going to look at what happens between BMS's that are used in a parallel configuration. This is important for several reasons. 1 - what happens with the settings, is one a master the others become slaves - controlled by the dip switches unless you have a Seplos V3 2 - what happens if you already have one battery that has been in service and you add a new battery and the new batter has new firmware. In this case, which one would you make the master 3 - in a real world scenario, what is the best practice when adding a new battery to you battery back.

If there is not enough sun and the (max possible) tail current can´t be reached the battery won´t be set to 100% ´couse of the voltage drop in the higher knee of the charging curve.
