Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Thank you. FYI, I'm using 0603 size which is not much harder than 0805. Prices might get lower one day, but for now I don't think I can produce for lower than that. There are a few things that I could do, like removing the quite expensive wurth connectors for bare soldering pads (user would have to ...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Bill of material alone is a bit more than 100USD when counting with 100 Units. BOM goes down to approx. 90 USD with more than 1000 units. I don't think I can include the development cost + cost of manufacturing + small profits without staying at approx 200-250USD for now... My goal isn't to beat the...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Well, the only point I agree with you is #8. BMS would act a bit as a VCU if your idea was implemented properly. I think the phone app would be a good way to do it without adding cost. Other points you are mentionning are already available/implemented with Master-LV or HV boards... Removing some fun...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Going 24S would increase the price & the size by a large factor as I posted previously (power supply size & control IC voltage tolerance) even 18S is a bit over the limit, 16S is probably the limit for large current & with 100V IC... No magic IC exist yet above 100V! Unless someone shows me how to d...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Also, I just changed this morning some settings for charging, I relaxed some safety protections that were maybe problematic when the voltage monitoring settings are not perfectly set-up.

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

@ fillupc : I fixed your toggle switch issue at charging in the V1.1 firmware

P.S. You will need to download & use the ENNOID-BMS tool V1.1-pre with the new firmware
https://github.com/EnnoidMe/ENNOID-BMS-Tool/releases

Thanks for reporting the bug

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

OK, I believe you. I will review the code when toggle setting is used. This is for sure a software problem with toggle switch option.

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Ok, I was wrong with my first assumption then, but it still shows me that the charging mode is not engaging as it should... there might be a problem with the load voltage measurement circuit. Also, when you connect the charger, the type of switch (toogle or pulse) has no impact on the BMS. the switc...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Yes I received the schematics. It would be super nice if the actual type of error would show up in the debug console. More error code for helping troubleshoots will be implemented one day. If the key is left ON, it will charge. It''s set to charge 18 cells to 4.15v per cell. It always shows error ri...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Exactly. I want to use the toggle setting due to wiring through a key switch. In this case though, with the switch off, when I connect the charger, the bms comes on briefly, but in under a second it shows "Bye" without ever engaging the charger relay. If I leave the switch on, charging works fine f...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

You mean different behavior of the BMS when you use pulse or toogle option in the ENNOID-BMS app?

I'll review this part in the firmware code this week end and will try to figure out why this bug could happen...

For the schematics, sure!

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

1. When PushButton(wired through key switch) is set to Latching/Toggle, chargeDetect will not keep the BMS powered on without the key being on. I would greatly prefer to charge without the key on. The original ENNOID-BMS charger detect circuit does not need the push button input. The BMS should nor...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

but if people leave a usb cable in it during operation to pull data from the unit it will put quite a bit of strain on a -relatively speaking- delicate connector type. prehaps a middle ground in a mini instead of a type b? The USB connector is not meant for permanent monitoring, but of course someo...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

For E-stop: I'm using the 12V output line for positive main contactor, so noise coming from the cable length should not be a problem. I don't think large standard Type-B is really required, but yes there could be still enough space... For USB, I switched to vertical micro-USB, so now all connectors ...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

Yes you can monitor a 20S pack with 2 slave boards each monitoring 10S... you need 2 slaves and a master-LV board. I also offer a box called "penthouse" on my website which hold the master-LV board + contactor + 12V power supply. Just connect slaves boards, battery & load power cables and you are re...

Re: ENNOID-BMS for 48V to 400V lithium-ion battery pack

would a 2 pin connector connected at the contactor coil positive or negative be a option? If I understand well your idea, it would just need an additional connector on the PCB in serie with the 12V & main contactor loop for connecting an external e-stop or just put a jumper if not needed. Sure that...
