# Features
- Protocol converter from the JK-BMS status frame to Pylontech CAN frames.
- Supports sending of total capayity for **SMA** and **Luxpower** inverters.
- Optional linear **reducing maximum current above 80% SOC** (values can be adapted to your needs).
- Support for **multiple BMS**.
- Display of BMS information, Cell voltages, statistics and alarms on a locally attached **serial 2004 LCD**.
- Page button for switching **5 LCD display pages**.
- Debug output and extra **CAN info** and **Capacity info page** on long press of button.
- Statistics of minimum and maximum cells during balancing to **identify conspicuous cells**.
- Switch off LCD backlight after timeout (can be disabled).
- Beep on alarm and connection timeouts with selectable timeout.
- Serial.print() function is still available for monitoring and debugging.
- SOC graph output for Arduino Serial Plotter at startup and Capacity Statistics page. Clear data on long press.
- The voltage in the SOC graph is corrected by the automatically computed ESR to get a smoother voltage curve.
**If the Aduino IDE complains about more than 100% of program storage space, burn the Uno Bootloader on your Nano, if not already done, and select the Uno as board. The Arduino Nano board definition has a [wrong "upload.maximum_size" value](https://github.com/arduino/ArduinoCore-avr/pull/546).**
Look [here](https://github.com/ArminJo/JK-BMSToPylontechCAN/blob/main/JK-BMSToPylontechCAN/JK-BMSToPylontechCAN.ino#L139) for options to reduce program size / add optional features.
**On a MCP2515 / TJA1050 kit for Arduino you must [replace the assembled 8 MHz crystal with a 16 MHz one](https://www.mittns.de/thread/1340-mcp2515-8mhz-auf-16mhz-upgrade/).**
**The MCP2515 / TJA1050 kit for Arduino may be supplied by an extra 5 V regulator. My Arduino-Nano internal regulator cannot provide more than 100 mA and got defect on my site after a few days.**
**By default, the program sends a request to force charge the battery if SOC is below 5 %. This can be adapted by changing the line `#define SOC_THRESHOLD_FOR_FORCE_CHARGE_REQUEST_I 5`.**
At around 100% SOC, the JK-BMS seems to send strange current information of more than +/- 1 ampere.
If CAN communications breaks, the inverter may use different values for controlling the battery (e.g. "Use Batt V"), which may lead to additional discharging / charging.
# SOC graph for a 16S LiFePO4 battery
Created by attaching Arduio 1.8.19 Serial Plotter and then doing a long button press followed by a single one to enter the capacity info page.
Here you see a steep capacity increasing at the transition from 100 % to 99 %.
This happens when the specified capacity in the BMS is smaller than the real one.
The new 99 % represents a bigger capacity than the old 100 %.
If the capacity is around 100 Ah, the gradient of the capacity and the SOC line is identical.
Here the current is not negative for 99%, because it is the average of the current above 100% -increasing the capacity- and the negative current delivered for the step from 100% to 99%.
The voltage line is smooth, because it is corrected with the ESR (Equivalent Series Resistance) of the battery.
The same (raw) data without ESR correction of voltage.

# Youtube video of JK-BMS doing wrong computing of capacity.
I discharged the battery for 10 minutes with 45A, which gives **7.5 Ah** capacity loss.
Start of 10 minutes period is left screenshot with time of ...**21M40S** and Capacity **50.7 Ah**, end of period is right screenshot with time of ...**31M40S** and Capacity **38.6 Ah**.
These 2 values correspond to a **capacity loss of 12.1 Ah** (50.7 Ah - 38.6 Ah)!
SOC went from 40 % to 30 %, which at least corresponds to 12.5 Ah for a total battery capacity of 125 Ah.

# Example on Wokwi
Also usable as connection schematic.
- [Wokwi JK-BMSToPylontechCAN example](https://wokwi.com/projects/371657348012321793).
# Connection schematic
The standard **RX** of the Arduino is used for the JK-BMS connection.
A **schottky diode** is inserted into the RX line to allow programming the AVR with the JK-BMS still connected and switched on.
Keep in mind that programming will fail if JK-BMS is connected and switched off.
The standard **TX** of the Arduino is used for Serial.print() for monitoring and debugging. The short **request to JK-BMS is sent by `SoftwareSerialTX` using pin 4**.
If you use the cable from the separate RS485 adapter of the JK-BMS and follow the labeling on the board, you have to **swap the lines for RX and TX (pin 4)** on the Uno / Nano.
**Troubleshooting BMS receive problems**
Since the RX pin of the Nano is also connected to the TX pin of the USB converter chip (CH340 or similar),
it can be difficult for the JK-BMS TX output to pull it properly down.
This results in not receiving any data from the BMS despite the connection.
In this case, first try to remove the diode and second connect a pull down at the Nano RX.
Depending on the USB converter chip, this pull down can be in the range from 680 Ohm to 1 kOhm.
**Power** is taken from an **USB power supply** connected to the Nano. Current is 40 mA for a dark 2004 display and 55 mA for a bright one.
Optionally, power can be taken from the second battery (>6.4 V), but then you may require an external 5V regulator. My built in regulator broke 2 times (with LCD connected).
Or use the complete battery voltage for Nano supply and a buck converters for around 48 to 60 volt. But my test converter had an idle current of 6 mA (0.3 W), so I decided to stay with the USB power supply.
On the Deye, connect cable before setting `Battery Mode` to `Lithium`, to avoid alarm. `Lithium Mode` for Pylontech CAN is `0` or `PYLON`.

# Principle of operation
1. A request to deliver all informations is sent to the BMS (1.85 ms).
2. Wait and receive the BMS status frame (wait for 0.18 to 1 ms + receive 25.5 ms).
3. The BMS status frame is stored in a buffer and parity and other plausi checks are made.
4. The cell data are converted and enhanced to fill the JKConvertedCellInfoStruct.
Other frame data are mapped to a C structure.
But all words and longs in this structure are filled with big endian and thus cannot be read directly but must be swapped on reading.
5. Other frame data are converted and enhanced to fill the JKComputedDataStruct.
6. The content of the status frame is printed. After reset, all info is printed once, then only dynamic info is printed.
7. The required CAN data is filled in the according PylontechCANFrameInfoStruct.
8. Dynamic data and alarms are displayed on the optional 2004 LCD if attached.
9. CAN data is sent.
# Compile with the Arduino IDE
Download and extract the repository. In the Arduino IDE open the sketch with File -> Open... and select the JK-BMSToPylontechCAN folder.
All libraries, especially the modified ones, are included in this project.
It is always recommended to burn the Uno bootloader on a Nano board, and trating your Nano board as an an Uno board for Arduino compiles.
This will give you 1.5 kB more program space, without any disadvantages. Even A6 and A7 are available :-).
# Compile options / macros for this software
To customize the software to different requirements, there are some compile options / macros available.
These macros must be defined in your program before the line `#include "JK-BMS.hpp"` to take effect.
