Please understand the concept and working of the SIMPbms,
it uses the slave-boards of the Tesla module, designed by Tesla... to balance
check the board on the module, and have a good look at the smd resistors that are supposed to burn off the energy to balance
then perhaps take a look at the...
Hmm, nothing too intelligent, but since this is a new battery pack, and there was this major incident with the old pack>>
perhaps start from scratch with a new flashed firmware. or even a new teensy 3.2, and take it from there to re-build your battery
not sitting next to you and the system in your workshop,
So here's my 2 cents: perhaps you have corrupted firmware, try flash a fresh new copy on your Teensy, and manually restore settings
did you recycle the original cable??,
it should not be difficult,
just make something from 2x 4 matching lenghts of 1mm2 multi strand wire,
twist TX&RX, use nice 4 pole female/male connectors, and you're done
I you are about to make your own, perhaps follow instructions as per manual...
Ben, did you try swapping rx/tx wires of the Nextion, perhaps not connected correct....
another question did you see Nextion boot up showing SIMP logo??
could it be you did not flash SIMP firmware on Nextion??
as always giving support is a lot of guesswork my end,
best of success with your...
Ben, mr. Widmore
There are 3 ways of measuring SOC in your set-up: 1) your MultiPlus 2) your Smart shunt or 3) the SIMPbms
My take have a go at the Smartshunt, as you have shed out the money already
Read Manual for SIMP how to deactivate voltage based SOC
read the manual of Victron for...
The BMS is supposed to safeguard the battery, please use a set of contactors or trip shunt breaker controlled by SIMPbms
to isolate and shutdown the system in case of an error, or simply when battery is full, allow discharge etc, all there in the manual
I'm not so sure Solar-assistant can do...
so we have a continuous supply of VAG VW MEB modules,
and tried out something.
110kWh of VAG MEB modules in a 2 string 2x BMS setup connected to Victron Cerbo
this is a teaser as how to make large storage batteries, using second-life VW ID3/4 (Skoda Enyaq) NMC batteries
modules are 12S...
SIMPbms Teensy arduino breakout board + BMWi3 firmware will work with BMW i3 BMW i8 and e-MINI,
so I think you're trying to use the wrong battery.
It is not working with BMW hybrid battery packs, at least we never tested it.
with the right BMW EV second-live battery,
easiest way of connecting...
