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: Denzel D9000 motor any thoughts?

I bought the D9000M (potted coil version)+Deco M 275A controller and just tested them together yesterday. I paid 640USD, shipping to Canada included and strangely, I did not have to pay any customs fees. The kit came with a complete wire harness for e-motorcycle including voltage display, throttle, ...

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...

Re: Quality Programmable Sine Wave Controller?

I bought several motors in the past from this Alex Guliyant from eastgem.net without any issue, so I decided to give a try to the deco-M+D9000 motor kit and placed and order in October. I received my controller+motor about a month later, but without the windows software that should comes with it. Th...

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

I'll keep private PCB & gerber files for now and will keep selling populated PCB on my website... There is no MCU on the slave boards, but there is several registers in the embedded IC that need to be initialised/set. Master boards does it through ISOSPI when connected to the slave board. The values...

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

So far, feedback are mostly positive, it does what it is supposed to do: allow precharge/discharge/charge/balance & monitor, but of course there are some little things to improve on both hardware & software. I have some people who bought Master-HV for electric vehicle conversion and other bought it ...

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

do you plan on having either a strip of a few leds of a breakout connector for a led bar that can light up to display basic errors like current or voltage errors or com link faults so you can do fast disanogsing without having to plug in every time? There is an oled display connector for that at th...

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

I'm a little confused by the new LV design. Is the '+' side of the charger and load connected to "Load +" terminal? Yes, I designed the system for Master-LV such a way that load & charger can use the same terminals. I then use discharge coil output for both load & charging function. There is a spec...

I'm placing an order today for slave board based on LTC6813 (18 cells in series per slave). So I should have them assembled in a few weeks in the worst case... I have been able to keep the board with the same physical dimensions of 60mm x 100mm. Pin placement is also the same between all slave board...

Re: Fuse-wire for individual cells, DIY Tesla style

Yeah, I thought about it as well. Sure, it would work with SMD fuse & spotwelding nickel strips, but... spotwelding is not a reliable enough process IMO and is hard to automate. Fuse wiring can be automated and act as a fuse, so final cost is reduced & reliability is higher. I should be able to get ...

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

Integration was the main reason why the contactors are bolted directly onto the PCB. The footprint of this type of contactor is almost a standard at this power level and at 49.99$, they are way cheaper than any other lower power level options and not much bigger. The goal was that the end user has n...

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

Going with a 4 layers board, it would be easier to place all the connectors on only one edge of the PCB, but for a 2 layer board, that is more complicated. I can still improve a bit, but they won't be all on the same edge... I would go with 4 layers if the board could be made smaller, but the gain w...
