Das REC-BMS ist doch "Steinzeit" gegen das aktive Autarctech-BMS mit dem LTC3300. Ich würde mir wünschen dass ich irgendwo so ein aktives BMS, allerdings für E-Fahrzeuge geeignet und kaskadierbar bis in den Hochvolt-Bereich hinein kaufen könnte. Leider arbeiten die aber scheinbar nur mit OEMs zusammen ? Sei doch froh wenn du dieses 48V-BMS überhaupt geliefert bekommst, das ist wirklich momentan die "Creme de la Creme". Wie teuer ist denn sowas in der 16s-Ausführung ?
Hello All,
I have a REC Q16S Sunny Island compatible in my set-up,
72Kwh second life Mitsubishi Outlander PHEV Yuasa LEV40 batteries
15S 32P 56.25 nominal Voltage, max voltage 61.5V matching voltage span of the SMA Sunny Island series.
1 SI-8.0 single phase
14.2Kwp solar genarator
At the time of start of my project end 2016, it was the only bms I could find that had canbus connection with the SI series.
See thread Nissan Leaf in an Sunny Island setup.
I merely copied Tronds example, and was happy it worked.
Cons:
not easy to expand to more cells, since you need a master- slave configuration.
soft ware is limited, yes it has a webgui interface, but special commands,
like setting charge amps etc are done in command line.
Pros:
very helpful service desk, e-mail response 24hours
REC has developed canbus interfaces to Studer, Victron,
if you have the canbus protocol Tine Andrejasic will import it in their REC bms
However, I have come across a alternative, http://www.batrium.com.
not local Europe, but Australia.
But what a difference, nearly open source, major inverter brands supported Solax Victron Studer and a lot more is possible.
Cons
far away, shipping not really cheap, slow in their e-mail response
Pro's
price wise for the product I think OK
great software,
great community,
loads of youtube editorials

If I had the choice now, I''d buy a Batrium bms
Hello Carel
I also took a look at the Batrium-BMS in the past like you and think it is one of the best available solutions at the moment at a good price but it's no active BMS like the Autarctech. Thats a big difference in function.
Another point is that it's not centralised with a balancing board to mount on every cell like the REC . Thats ok for a stationary battery but not so good for automotive usage.
many regards
Klaus
Hello Klaus,
well said, you are right,
not so good for automotive,
but I'm interested in controlling features, in battery storage solutions,
using second -live ev batteries.
I think Batrium will do the job very well, may well be better than REc
The company just released their Batrium Watchmon 4 bms,
I was saving up some money,
and probably will order one of these new kits to evaluate.
Once I have it, will write a review.

Any news here?
Yes, and no- not really.
Batrium is developing a new product Watchmon Plus, capable of balancing 6A,
Looks promising
But i went another route aimed at second-life ev batteries using existing oem cmu pcb board with an Arduino based master control unit.
With the Simpbms one can control Tesla modules, YUASA cells found in Mitsubishi Outlander, in development is VW/BMW ev batteries.
see snapshot photo's of SIMPbms board, and test riggs
SIMPbms works out of the box with Victron and SMA Sunny Island range,
At the moment we are working on a set-up with Simpbms and HV SMA Sunnyboy Storage series, together with Tesla modules and 12Kwh 320V Yuasa cells from Mitsubishi Outlander
