Battery-Emulator - v8.3.0

What's Changed ๐Ÿ“ฆ

This version fixes a few bugs, adds support for some new components, and replaces the MQTT library. We have been using an older version that stopped getting updates in 2020. This is now fixed by switching to the official Espressif ESP-MQTT library for improved cybersecurity and more features

[!IMPORTANT]
The new MQTT library takes up much more program space. It is mandatory to change "Tools, Partition Scheme" to "Minimal Spiffs" from here on. This is explained in the Quickstart video. Failing to change this might result in a Sketch too big compilation error. See the picture below on where to set it:

What's Changed ๐Ÿ“ฆ

This release adds support for Sono Motors batteries, Growatt LV inverters, and a ton of bugfixes. It is especially recommended for Volvo/Polestar users, since it contains some well needed improvements there. Be sure to read thru the release notes before installing this new version!

[!NOTE]
Note, this version drops support for MCP2517 chips in favour of the MCP2518FD chips. This is to ensure proper CAN-FD timing requirements. By removing the hardware workarounds needed to keep a 2517 chip operating, we speed up the 2518FD operation. This change should not affect anyone, since no hardware designs have been made with 2517

[!IMPORTANT]
To take into use a 8.X.X version, Copy/Rename the USER_SECRETS.TEMPLATE.h file to USER_SECRETS.h and update connectivity settings inside this file.

Battery-Emulator - v7.2.0

What's Changed

This release improves OTA behaviour of the Battery-Emulator significantly. We now pause the battery operation before an OTA update is started. This avoids premature contactor wear, and makes inverters less likely to trigger fault codes. You can also manually trigger a pause from the Webserver. Pauses generate events that can be seen in the event log. Bonus, the OTA view also specifies which software/hardware version you are currently on.

This release also improves MQTT functionality , events are now sent via MQTT!

Finally, this release adds authentication to the Webserver. You can now protect it with an username and password!

Battery-Emulator - v7.1.1

What's Changed

[!IMPORTANT]
It is highly recommended to update to this version.

This release fixes a single issue, event EEPROM writing causing the code to halt for up to 70milliseconds. This caused contactors to open on some battery setups, since CAN message reading/writing was essentially blocked when events were stored to EEPROM. So for now, events wont be stored to persistent memory until we can find a way to do so without halting the program.

The CAN configuration needs to be set incase you are running extra CAN channels attached to the board. Via this new configuration option, you can define what is connected to which CAN channel. Some components are OK with sharing a CAN channel, others need a dedicated channel. The new CAN configuration also allows you to connect normal CAN devices to a CAN-FD interface. Simply enable the USE_CANFD_INTERFACE_AS_CLASSIC_CAN option in the USER_SETTINGS incase this functionality is desired. There is a whole lot more flexibility with the newconfiguration CAN configuration interface!

  • Add platformio serial logging by @kukumagi in https://github.com/dalathegreat/Battery-Emulator/pull/251
  • Refactoring: Scalability and performance by @Cabooman in https://github.com/dalathegreat/Battery-Emulator/pull/252
  • Introduction of a rudimentary hardware abstraction layer (HAL) to handle other boards
  • Untangling of settings - config.h and various other settings have moved to any of: system_settings.h hw_lilygo.h or related implementation files (e.g. WUP_PIN -> BMW i3, for now)
  • MQTT handling moved to its own task with slightly lower priority
  • Include handling improved, most files can now include "src/include.h" to get the central settings/definitions
  • An initial data layer is introduced in a moderate fashion, for Nissan Leaf power values and time measurements
  • Mapping functions supporting mapping of some value in one range to the corresponding value in a different range
  • Slightly improved compilation times by having preprocessor conditions on inverter code and charger code

Battery-Emulator - v5.6.0

What's Changed

Massive efforts have been made to reduce CPU load drastically in this version, to improve CAN sending reliability and timing. Some users noticed that BMW i3 batteries opened contactors when Modbus requests were coming in, causing 10ms periodic messages to get delayed to 200ms. This is unacceptable for an embedded realtime system. This new version not only lowers CPU usage, but also warns the user via Events incase the sending of CAN messages start to get delayed.

  • Autoupdate of the pre-commit configuration
  • CPU load improvements:
    • Event added for notifing users incase CAN message timing starts to be affected
    • Mainloop now runs as background task with same priority as modbus
    • Webserver loads 30% faster
    • Pressing "Event" button in webserver caused the sending of 10ms CAN messages to skyrocket to 185ms. This is now fixed

Inverters

  • Bugfix: Solax inverters no longer get stuck with open contactors at 0%SOC
    • Inverter contactor opening changed from Error -> Info event
    • CAN interface is now restarted incase Solax has timed out

Batteries

  • Triplet battery:
    • Cellvoltages now mapped to the global array, and can be viewed in webserver cellvoltage view
    • Temperature values scaled correctly
    • Revised safety limits for under/overvoltage
  • BMW i3 battery:
    • Current value now scaled correctly
    • Power value now calculated correctly
    • Fixed an issue where max allowed charge/discharge would overflow

Battery-Emulator - v5.2.0

What's Changed

New features

  • This release adds event handling. The webserver can now display a list of events that have triggered in the system. For instance anything out of the ordinary; cell overvoltage, overheating, CAN failures etc. all get logged to the event list. The events are also stored to EEPROM for an additional layer of security. Event handling makes troubleshooting a problematic situation much easier. Massive thanks to @Cabooman for implementing most of it ๐Ÿ™Œ

bild
The event log can show you how many events have occured, when the last event of this type happened, severity of event and data. Events get stored to EEPROM, so if you later on power on the board, it will spit out the last events via serial on bootup. How neat is that? ๐Ÿ‘

Note for devs: Events should be used for further development of all battery handlers, since it centralizes the writing of BMS status and handling of LED color and serial printouts.

Battery-Emulator - v4.2.0 release

What's Changed

The Battery-Emulator can now act as a Webserver! You can now remotely check in on what the LilyGo is reporting, and also update software over the air! How cool is that? ๐Ÿ˜Ž When the setting 'WEBSERVER' is enabled, Wifi settings can be tweaked in the 'USER_SETTINGS.cpp' file. For more info on what this feature brings, see the pull request description

Got a tricky inverter that doesn't like to see automotive CAN messages on the same bus as inverter messages? No worries, you can now use two LilyGo's at the same time! One connected to the battery, the other to the inverter, these then share data between each other via the RS485 pins. Elegant solution to a tricky problem!

Battery-Emulator - v4.0.0 release

What's Changed

โš ๏ธ NOTE: Due to the refactoring and addition to new parameters in USER_SETTINGS.h, it is required to start with a fresh user settings file when taking this release into use! โš ๏ธ

  • The code now has been refactored to be more user friendly (Thanks to @lenvm ๐Ÿ‘)
  • The entire project now has pre-commit code formatting checks in place (Thanks to @lenvm ๐Ÿ‘)
  • Github Actions added, all possible combinations of inverters/batteries now tested so that they compile, by @lenvm in https://github.com/dalathegreat/BYD-Battery-Emulator-For-Gen24/pull/84 This improves code quality in the long run.
  • Min/Max voltage now uses global value for all inverters to save memory

Inverters

  • BYD CAN: This PR adds a new parameters (MAXCHARGEAMP & MAXDISCHARGEAMP) to the USER_SETTINGS.h file
    281544935-08cb6d76-f384-4eb4-b08b-7a674d012362
    • You can now specify the max charge A and discharge A that will be sent over BYD CAN protocol. Some inverters did not like having over 30.0A available, so now you can restrict the value!
    • Also removed the blocking of some CAN messages in BYD can when the FAULT state is active. This was not needed.

Batteries

  • Added a new Test Mode. Now you can enable a fake battery to test your inverter without a real battery on CAN bus. This can be enabled in USER_SETTINGS.h , by uncommenting the line #define TEST_FAKE_BATTERY

    • When enabled, the values set in TEST-FAKE-BATTERY.cpp will be sent towards your inverter of choice.
    • While in this test mode, the LED on the board will cycle thru all RGB values, letting you know you are in a special mode.
      VID20231115190406(1)

  • Tesla batteries

    • Fixed a bug where Amp value was scaled incorrectly, causing inverters to report wrong W
    • Fixed contactor opening for fault scenarios, the known working delay for sending 0x221 messages copied from pelle_c!
    • Debug printout made easier to readd
