Simp BMS

Gwizard · Post by **Gwizard** » Tue Oct 24, 2023 12:46 pm

Hi All this is my first post on here.

I recently purchased A VW passat pack to upgrade my home battery / solar setup (this is a 360V 96s system if anyone is interested) and immediately ran into the teensy 3.2 shortage problem.

I have my own modified version of simpBMS which can send a JSON string via Wi-Fi to my home automation system via an ESP8266 of course.

I spotted that someone had kindly ported simp to the teensy4.0, the code worked and compiled as expected however many of the cell voltages were being missed. This appeared to be the first few cells on the first few modules.

After trying many different approaches I discovered the problem seems to be with the FlexCAN_T4 library, it seems that some packets are not received following a can send.

If I comment out the sendcommand() function call and send the 0x0BA command from linux via my can sniffer, I get all the voltages, proving the hypothesis. I did try converting simp over to an interrupt driven approach to receiving can messages but this had no effect, the messages were still lost unless send from and external source.

So a very long story short I moved the send command function call to

if (millis() - looptime1 > settings.chargerspd)
{
sendcommand();
looptime1 = millis();
if (settings.ESSmode == 1)

This effectively gives enough time for FlexCAN to get its act together before polling for messages.

I hope this helps someone

Cheers

Very strange would not expect that. All my new products currently use the Teensy 4.0 without any problems like you described it must be a sloppy port. I fully rewrote all my functions for my new firmware though.

Hi Tom, I don't know but it's one to keep an eye on for anyone using the FlexCAN_T4 library in case it crops up in any other projects.

Thanks

Hi, SimpBMS reports HV voltage on id 0x356 over two bytes (MSB and LSB). Could somebody help to combine those two bytes into a single hex voltage value for arduino Due board?

In the Arduino code?
Not sure what you upto.

But combineing 2 bytes into a 16BIT.

Int8 byte1 = 0;
Int8 byte2 = 0;

Int16 vint_16 = ( byte1 <<16 ) + byte2;

Hi,
I am using an EVS BMS with VW MEB 12S modules. The BMS is working, but now I want to balance the cells (properly this will take weeks, but anyway).
The battery status shows "Balancing Active" and sometimes "Balancing Paused":

Code: Select all

 Temp 1: 8.50C Temp 2: 0.00C Status: 0x0 Bal: 0x0

But I have the impression that it is not balancing (cell voltage did not change after 24hrs).
The contactors are OPEN when I am trying to get the cells balanced.
What does the "Bal: 0x0" mean?

I have sent you an PM with a request for some debug info. MEB Balance status is not fully interpreted at the moment.

Hello.
My first time upgrading the Tesla2BMSV2 firmware. Arduino IDE throws warning messages. Could somebody please confirm whether these can be disregarder? These look like mainly due converting\comparing variables of not matching types.

My first time upgrading the Tesla2BMSV2 firmware.

Why are you compiling? There is a .hex you can upload. If you compile your own versions then giving support on any issues is not really possible due to library changes ect.

ok. Learned something new. I'll try the .hex file. Is it the most up-to-date? Shows a month difference between the project and the .hex.

Yes it is, only gotten something in it someone wanted to do. Specific to their usecase, it is not an update from me. The .HEX is from me.

alexbeatle · Post by **alexbeatle** » Fri Apr 05, 2024 7:18 pm

I'd like to verify something, please.
I have 14 Tesla MS batteries in series - 5.3kWh, 232Ah each. None in parallel.
When it comes to setting the battery pack capacity the firmware defaults to 100Ah. Is that a precautionary value since diy batteries aren't new so this to be left as-is or changing to 232Ah is safe?

Another question - simpBMS + LIM.
LIM needs battery capacity in Wh with 0.1 scale.
So confirming this is the correct way to calculate it.

Code: Select all

Wh = Ah * Max. Pack Charge Voltage

These are available from the simpBMS CAN messaging:
Ah= 0x379 byte[0] and byte [1];

Code: Select all

 msg.id  = 0x379; //Installed capacity
  msg.len = 8;
  msg.buf[0] = lowByte(uint16_t(settings.Pstrings * settings.CAP));
  msg.buf[1] = highByte(uint16_t(settings.Pstrings * settings.CAP));

Max. Pack Charge Voltage aka. Charge Vsetpoint = 0x351 byte[0] and byte [1]

Code: Select all

void VEcan() //communication with Victron system over CAN
{
  msg.id  = 0x351;
  msg.len = 8;
  if (storagemode == 0)
  {
    msg.buf[0] = lowByte(uint16_t((settings.ChargeVsetpoint * settings.Scells ) * 10));
    msg.buf[1] = highByte(uint16_t((settings.ChargeVsetpoint * settings.Scells ) * 10));
  }
  else
  {
    msg.buf[0] = lowByte(uint16_t((settings.StoreVsetpoint * settings.Scells ) * 10));
    msg.buf[1] = highByte(uint16_t((settings.StoreVsetpoint * settings.Scells ) * 10));
  }

The standard settings are just "random" you need to set the capacity yourself to what ever works. You can start at name plate and adjust when needed.

Yes that calc works, not 100% required to be accurate not all CCS chargers do anything with the info.

There seems to be many forks and copies of Simpbms git repo for different Arduino platforms (eg teensy 4, esp32) and chargers that are not supported by the official software. I plan to use my Teensy 4.0 (as 3.2 is no longer available) with X5 pack and Outlander charger. I've seen outlander support on some repos, but not sure which one to use. Any recommendations?

I was also thinking of using BMW Safetybox for precharge, contactor control and maybe for current sensor if possible. This way I wouldn't need anything else than added can transceiver.

Not sure if any of those simpbms forks support that combo, teensy 4 & outlander charger & safetybox?

rstevens81 · Post by **rstevens81** » Wed Apr 24, 2024 8:31 am

these forks are not affiliated with simp or tom, we are doing out own thing, unless you know what you are doing i would recommend buying either a real simp bms or the newer evs-bms from toms suppliers.

Although its fun developing a board for your own purposes and porting code the time spent will be questionable against just buying the simp bms. (i know because im the idiot that designed the spaceballs (esp32) pcb and wouldn't go as far to recommend it it to someone [due to the esp32 can bug & the beta nature of the code]).

in terms of sbox prob best go with zombie for that as thats known to work

Correct me if I'm wrong but simpbms is not for sale anywhere as far as I can tell.

Yeah, well aware of that. Though, I would probably buy that evs-bms (or discontinued simpbms) if it would support that combo.

ESP32 is less than half price of Teensy 4, but was there some other advantages using ESP32 instead of Teensy 4?

I could have a stab doing that port myself. I'd like to have only one Arduino doing all this stuff. Less wiring and less devices communicating with each other = less problems. BMW Safetybox sources/info seems to be here https://github.com/damienmaguire/BMW_SBox

Found this BMW PHEV & Outlander charger repo https://github.com/aot93/BMWPhevBMS-OutlanderCharger

Would be great if there would be BMWPhevBMS repo with Teensy 4 support. Maybe there is?

I can look at adding the saftey box into the EVS-BMS supported ones. Yes I do not know if the Sbox can live on the same bus as the battery modules and still work. Luckily the EVS-BMS has two CAN busses.

I tested this last year. Battery modules and Sbox clash on id 0x100 so can not share the same bus.

I spun the wheels of my car with the full pack today for the first time. After 10mins or so, BMS went into "error" claiming series connection fault. Even after the motor stopped spinning.
Never had this before previously- when motor stationary or running at half-pack sometime ago. After rebooting, BMS went into ready, but still "series fault", though then recovered.
I have 2 packs. 1st pack - modules #1-5, 2nd pack - modules 6-14.
Any clue what could cause this?

Do you mean EMI?
