Since my last visit here we've done a lot.
I've been working on a new test rigg.
SMA Sunny Island LV DC inverter charger + Simpbms + GS YUASA LEV40N/50N cellblocks with CMU
I've reported earlier on the SIMP bms here :
other info can be found here:
The current firmware version of SIMPbms can adres 10 unique cmu ID.
so max set-up =5S16P ~12Kwh LEV40N or 14Kwh LEV50N, or perhaps better go with 5S15P (note alll cells are monitored by CMU)
SIMPbms is a shield with a Teensy 3.2 capable to work with/control various oem EV batteries and their cmu's,
like Tesla BMW VAG (VW-Audi) Mercedes Benz GS YUASA Mitsubishi Outlander /iMIEV and clones from Peugeot/Citroen.
Porting this SIMPbms to brand name inverters is in slow progress.
First was the Victron range via Venus OS on the Venus GX, and the Color GX, as described earlier.
now we have the SMA Sunny Island series working.
Next step will be giving it a try to go High Voltage, SMA Sunnyboy Storage series.
Hooking up a complete pack 400Vdc, controlled with a SIMPbms to one of these:
If somebody from the forum has the can-protocol of this SunnyBoy Storage range, and is willing to share, please please do.
All work is on Github: https://github.com/tomdebree
I will try to update this thread with additional info as we progress, if permitted
