Hi, new member. I hope it’s okay to do this, if not, please let me know and I’ll delete it. I’m not here to ruffle any feathers.
As a bit of background, I own a small battery company in Australia.
We design and sell LiFePO4 batteries and are somewhat innovative as well. For example one I got JBD to develop a 250A smart BMS with an output (through an optocoupler) to turn on and off a 5A active balancer whenever the onboard passive balancer turns on.
But I’ve also got a more ambitious BMS design in mind and was hoping that perhaps one of you might be able to help.
So, I’m also looking at building a hybrid starter battery that uses LiFePO4 and supercapacitors (happy to go into detail later).
For this, I want a 100A 4s BMS. There are hundreds to choose from, but what I want doesn’t seem to exist yet, as I also want it to have an integrated PWM that utilises the MOSFETs to modulate the current to 100A max (ideally the maximum current would be able to be set, either via Bluetooth or even through flashing firmware).
This is outside the scope of my skills, so I’m looking to see if there’s anyone that might want to develop something like this and I’ll pay an agreed amount.
To give back to the community, I’d also be happy to make both firmware and hardware open source.
If anyone is potentially interested, please let me know and we can either discuss on here or set up a Zoom call.
Again, hope this doesn’t go against any rules!
