[GCinDC]

has to do cell board config...

 

[ridethelightning]

Plugged it all in this morning and had a few error messages as I have not done the full setup (I presume).

Could someone explain what is meant by this;

Next, enter the Menu -> BMS setup -> BMS setup. There made all the settings BMS.

Each expansion card should have your number. The new BMS expansion cards are numbered in order and are numbered from 1 to 7.
In the configuration of BMS (Channel A config) must specify how many cells which extension serves. The extension module may be either off (0 cells), or 2,3 or 4 to interrogate the cell.
Poll 1 cell expansion module can not. So if you have the last expansion module accounts for one cell, then the penultimate board takes another cell and 3-cell configuration is obtained on the second board and 2 on the latter.

Any help would be appreciated

By the look of your cell monitor one of the connectors is either in the wrong socket or not wired up right.

i think you may have the boards ordered in the wrong direction.
the first board(cells 1,2,3,4) is near the cable ponytail, the top board is the last of the three "split off" boards.
its confusing cause the jst plugs are flipped so that the top pos+ of each board is closest to the cable ponytail,the bottom neg- is at the "split off" end of each board.

so- youv got the jst plugs in right(its the only way they go ), just in the wrong order.

the 1st board is where the 20 is, and the 5th board is where the 0 is

Sorted at last

Board 2 is blown through my earlier endeavors it would seem.

As Crea2k suggested earlier, skip board to and re-assign the cells to another board.

 

[crea2k]

Good stuff, glad you got it sorted, yes I know from experience about blowing up bms boards, luckily there are spares depending on how many people run, so if you fry one you usually have two backups you can switch too instead before you have to buy a new bms.

sacko, it really sucks that you actually had it hooked up correctly the first time around.

If you use another BMS board, will the cells show in sequence on the display? Or will you have 4 cells in a row showing 0 voltage?

 

[sacko]

Definitely sucks that they were in the right order first time round, spend hours on that harness!

It shows all the cells in order.

Perhaps I'm misunderstanding the BMS. Please halp.


It lets you have up to 28 cells (or modules) in series. So if you have a 28S1P pack, you can monitor each cell invididually. But if you have an 18S10P pack, will it only let you monitor each 10P module? Example, if I'm using LG's 18650HE2 li-ion, it would balance at 25Ah module to 3.7 nominal, but not every cell would be monitored..?


How can you account for cell drift within the paralleled modules? This is of course assuming I understand the BMS. It's highly likely I don't!

Awesome. Thanks, you're an invaluable resource with this controller!

I'm still getting the "No charge voltage error"..

I'm trying to upgrade the firmware from Adaptto's site, however when I try to download anything newer than RC8, I open it in notepad and see it's the RC8F firmware. This happens for the Max-E, but appears to happen for the mini-E firmwares too. I've tried clearing downloads folder, different browsers, different machines.. When I flash the bike it doesn't turn out to be any newer than RC8F.

Am is missing something? Does anyone have a backup of the Max-e locked RC9e firmware?

 

[GCinDC]

the startup screen is not accurate for some reason. hit right button until you get health monitor, then go up. f/w version should be listed at bottom.

 

[Metallover]

Thanks! This is true. I did notice even though the files all said RC8F, they seemed a bit different.

Trying to fix my "No charge voltage, press down to exit" error..

A few weeks ago I rode the bike and got the state of charge to go down to about 70%, low power mode kicking in. I still was unable to charge. Took a break...

Today

My last attempt was: system reset-flash RC9e- remove sd card- unplug power-connect power- system reset- set up charging- no luck.. still "No charge voltage, press down to exit".

I believe my connections are good. Plugged in, in "charge mode" I can read 48V from my supply. The charging screen floats around 0.3V, then stays constant at 0.4V when my 48V supply is connected.





I remember Allex's post, also posted by user jeka on electrotransport

A few tips and tricks:
We recorded a few cases where controller burned due to wrong actions and (or) the old firmware. When you charge with and older firmware for several hours, like 8. This is now fixed with the new Firmware.

For safe charging you need:
1) Flash controller to the latest firmware
2) Before connecting the charger set controller to charging mode (left-up of the main screen)
3) Connect the charger
4) Connect the charger to a wall outlet
5) When finished, disconnect the charger from the wall outlet
6) Disconnect the charger from the controller.
7) Exit charge mode(button "down" on the screen of charge)
Paragraphs 3.4 and 5.6 can be swapped, but it is better to do it like above.

And about the new versions being slower on acceleration. This is because older version like rc7b did not limit phase current at the exact set value. So if you did set 250 it overshoot by 50, meaning you actually had 300.

Also, the new firmware will have support for PAS. But DC-DC mode will only be available in the unlocked version.

Maybe I have done this wrong, and damaged my max-e? If I can find someone who has experienced this damage, did they end up with this error when trying to charge?

 

[Allex]

Did you connect one cable from Coil into one of the phases while it is connected to motor at the same time? Many peopledo it wrong, disconnect it from the motor and trying to charge without result.

Yes, all three phases are connected to the motor. I've tried switching the positive leg of the charging lead to each of the other two phases with no luck. The bike runs just fine, so I bet all the phase wires are hooked up correctly.

My charging was working beautifully until one day it just quit working, with this error. I have about 150 miles on the bike.

I tried inverting the charge sensor; that just puts the bike in charge mode upon startup, with the no charge voltage error.

Another issue, is when I use the new RC9b firmware, and a few other firmwares, is that I can't go over about 18mph. When I run autodetect the motor revs up high like normal, 40mph. When I close out, I can put it on eco, normal, or boost, set the speed limit all the way up to 100+mph and change the OVS to 7 degrees and I am stuck at 18mph. Going back to older firmware, I think RC8c, lets me go back to the 40+mph I had.

 

[xenodius]

Did you check phase current, battery current, and other limits such as allowable voltage drop of the pack and so forth?

 

[Allex]

Reg speed, could be something with SPD smooth

 

[Metallover]

Thanks for the help guys! I appreciate it

I tried changing SPD smooth, max then zero. no luck. Speed limit in power profiles is 124mph

I've searched through the settings high and low. I could have missed something tho? For charging and top speed

 

[Offroader]

That sucks, It doesn't look good when something was working fine then for no reason stops working. Makes me think hardware rather than a software setting, but who knows.

I have to manually go into "charge setup" and turn the charger On to OFF and save settings for it to leave charging mode.

With my screen busted and not able to go through the settings I have to disconnect power from my controller to exit charge mode.

I wonder if your and my problem is in the controller unit itself or the display.

 

[crea2k]

Try your circuit tester from the charger right back to the board on the controller, just wondering if the connection to the board on the controller is bad and the wire going into the controller is dead.

 

[crea2k]

It shows all the cells in order.

If you go into the battery cell config settings and go to custom, and set the discharged cell voltage to 3.6 volts the power remaining, graph etc will be more accurate then, as your not going to be wanting to take the charge down to 3.00 volts, as that's what is set as the discharged voltage at the moment looking at the graph.

 

[crea2k]

Iv been putting this together today at work when I get a spare min, its written in html and jquery and calculates all kinds of battery pack info. Take a look and let me know what you think, and any extra info that might be useful to add in there. Its only setup to work with lipo packs at the moment, so id have to add other chemistries in there, so that the different cell voltages for it to make sense. I thought it would be useful for people setting up controllers and stuff as I know with my adaptto you need to know all the watt hour and amp hour etc and all the voltages, to set it up, so thought this would be easy as you can just input the info and it does all the calculations for you.

^Very useful application, definitely set it up for other chemistries!


Allex: for how long can the max-E sustain its 15kW output rating? The min-E its 6kW rating?

 

[Allex]

Those are peak ratings so I would say about one minute tops. But perhaps Adaptto could chime in here?

Thanks !, I felt there was nothing specifically just for ebike users, so thought id code something up. I will add in other chemistries too when I get a moment
