Welcome to Vintage Voltage part 2. Our first BMS was interrupted by me getting recruited to Tesla. Now, that was an experience I would never have missed, but it’s time to finish what we started.
The VVBMS is finally ready for limited distribution. Over two years in the making. We’re ready to have a few of you have a go with it, but we have to take it slowly. I’m older than I used to be. My About picture is a little dated, but I kinda look mostly the same.
We’re going to start the product introduction as a Beta program, for a number of reasons. First, we want to make sure our first few customers are ready for the challenge of working with this new product. We don’t have a lot of instructional materials available, so there will be a bit of instructing on the go. Second, is that the product is new, complex and will have issues. How many BMS’s you know of have 4 separate BMB communications interfaces? Third, is we want a diverse set of projects covering as much functionality as possible.
The signup process is fairly simple. Just fill out an introduction form here and let me know you are interested and we’ll go from there.
I live in Germany and I don’t know if this is the right place to ask questions that might also be of interest to others. I’ll give it a try. I have already installed a CAN bus shunt from Isabellenhütten (IVT-S). Can I read the current values via CAN instead of installing an additional LEM sensor?

Christian,
Thanks for checking out our product! That’s one nice shunt you have there. Isabellenhütten makes some good products, for sure.
The VVBMS does have a CAN port that can be used to communicate with the shunt, and Isabellenhütten was nice enough to provide a detailed specification, so it’s a matter of adding a firmware driver to the BMS. I’m sorry, but at this time, the VVBMS is not able to read that sensor, but should be able in the future.
Are you only using it for current, or do you use the voltage sense features as well?
