Hi Guys, Battery Monitor V2.1.8 or Battery Monitor V2.1.9 doesnt wanna work on my win10 pc, It only works on my win7 laptop, does anyone else have this problem?,

On my win10 pc, it starts up with nothing loaded, and then I want to import a protocol and get a nasty error?!

on my win7 laptop, I just fire the program up and everything is sorted, I just connect, no issues!

Also check the older setup guide in the google folder, it has extra steps to change the windows language settings and install the .net framework.

Right click the exe in Win 10 - select Properties, select the' Compatibility' tab, select 'Run this file in Compatibility mode' Select Win 7 from the drop-down. Select apply.

I've tried that already before posting my message here, it doesnt fix the problem

I also though it might be a .net framework issue, but when I tried to install .net framework, my win10 tell me I already have the newest version.

Just checking if you did this step as it is not in both installation manuals:

Wooow, that did the trick!!!  .....thx man!

I wonder if anyone have the perfect charging and float voltages for me, I'm using a Axpert inverter, and Shoto SDA10-48100 Lithium Battery 5.1kWh (16cell) battery

Charging at 56V and floating at 54V works very well. I have raised my float voltage to 54.5V to make sure it reaches 100% in bad weather as I don't have a lot of PV and no grid backup. Some cells need to reach 3.5V for the balancing to activate. You can try reducing them a little and see if your system still gets the battery to 100%.

I've got soo many questions and concerns actually, I bought 2 of those shoto 5.12kwh and a couple of days apart and linked them up in parallel, the first one have 10 cycles and second one have 5 cycles, but the first battery says Total capacity: 103.05 Ah and the second battery says, 100 Ah, how does that work?, does the BMS learn with time or what? and with the bms software, it looks messy, just warnings and red batteries mostly, and the SOC is about 98% max, I'm going to add a picture of my previous shoto battery and everything looks perfect!!  Shoto SDA10-48100L5 4,8kW

Ah yes, I found this very confusing at first, but then figured out why it looks like it's only charged to 98%... this is because it has already reached 100% SOC and the BMS won't allow charging again until it reaches 96%. That is what the "Intermittent Power Supply Waiting" message tells you, it is basically "Battery Waiting (to be discharged)". If you pull the history data you might be able to catch where it was at 100% SOC, but you need to be quick as it only gives the last 500 rows and when the battery reaches 100% the data is filled every few seconds with status changes. I did turn this off for a day or so to see what happens, but I didn't like the idea of the battery sitting at 100% all day.

The "Monomer High Voltage Alarm" basically means "Single-Cell High Voltage Alarm" and is triggered when any cell goes over 3.5V, but the passive equalization also only activates at 3.5V, so these warnings are 'normal'. They will go away as the battery settles after charging. My guess is pack1 reached 100% a little earlier and the cells have already settled. It makes sense that the slightly older battery has had time to equalize better.

As for the capacity change, I have not seen this yet, but technically yes the BMS is supposed to learn with time and update the SOH and capacity as it goes, usually it goes down though.

On the cycles, the BMS has a setting that counts as cycle at 20% cumulative discharge which is incorrect, so you will probably see the cycles counting a lot quicker than you expect. That can be changed in the parameters.

 This has been very insightful, awesome! ....I checked the "history record" and aha!!! 100%, how do you turn this option off so that it will stay at 100% SOC just out of curiosity? and 20% cumulative discharge seems a bit messed up, what should you recommend that gets changed to?

There are 2 options wrt the 100% SOC, there is the function switch called 'Intermittent Charging Function' on the RHS of the parameters window which will turn off the function completely and it will hover around 100% SOC. The second option is to increase the percentage at which it will start charging again which is parameter 80 'Interval Charge Capacity' on the LHS of the window, which is at 96% by default.

Parameter 81 is 'Cycle Cumulative Capacity' which is used to count the cycles and is set to 20%. I set mine to 90% as this battery is sold as 5000 cycles @ 90% DOD, so that makes sense to me.

Just be aware that I have no idea how changing any of these settings will affect your warranty, but I doubt it can be argued that changing the percentage at which the cycles are counted affects the battery performance at all.

I'm just going to put some screenshots of all the default BMS settings here for reference and for anyone interested who doesn't have comms set up...

Yea, your 90% Parameter 81 is 'Cycle Cumulative Capacity' makes sense, but I'll leave it on 20% just or warrantee purposes, I can't seem to get them higher then 98% SOC, I disabled the function switch called 'Intermittent Charging Function' and parameter 80 'Interval Charge Capacity' which is at 96% by default. can't be changed to 100%, the highest it will go is 99.9%, but the batts doesn't want to reach 100% SOC.... it stays @ around 98% SOC min

I must admit from my observation that catching the 100% SOC is not always easy with these batteries because once it reached 98% it enters a state where it constantly changes status from charge to standby to charge to discharge to standby to charge etc. every few seconds. The effect this has it that it reduces the current the battery allows in and ramps down the charging and it can take some time before the battery hits 100% SOC.

I'm so used to my old shoto battery that was always on 100% SOC and all cells was perfectly balanced!! ...This "Battery Monitor" tool is actually awesome but powerfull!! it pulls the log directly from the battery, you have to first set the time right tho under Calibrate or else the times on the log will make no sense!, the bms is like a computer itself! its awesome, the problem I have with the shoto 5.12kw is that it cutt off at 98% and it seems to just leave the cells unbalanced.. I've had some cells 3.7v max, 3.3v min and nothing seems to wanna balance.

EDIT: and when it goes to float, is discharges everything by -0.50A until it reaches float voltage of about 54v, and then you still have unbalanced cells, as everything is below 3.5v then... eish

Yeah, the BMS is quite an impressive machine. I calibrated the time a few times, but it always seems to be out so I stopped bothering. The balancing is passive so it burns off the charge in the higher cells above 3.5V, but it is only 100mA or something like that so it can take some time. I did change my float voltage to 54.5V so it still does some balancing when the inverter switches to float before 100% SOC. It might just take some time for the cells to balance nicely as the battery is new. I faffed with comms for more than 2 months so my battery was 'worn in' by the time I got the software connected. I fiddled around with the settings a lot in the beginning chasing the 100% SOC, I turned of the intermittent charge, lowered the equalization voltage to 3.4V, increased the charge voltage to 57V and few other things and realized after a while that the default BMS settings work fine, it was just my expectations that were wrong.

hello guys,

Someone know the administrator password for PMODBUSTOOS  (I guess it is the same as for the PBMSTOOLS) ?

This Pmodbustoos is the only software that works, I cannot make the Pbmstools to work, it times out on the "serial port" - same cable, same com-port

I use the USB to RS485 adapter.

Do these tools only work with Shoto -  Does Dyness perhaps have the Seplos BMS too as it uses the same pin-outs?

Baud rate must be the 19 thousand odd setting so it doesn't time out

They work with almost all batteries. Depending on which bus is used for comms you either use PBMS tools or PBMODBUS tools.
