Jikong JK BMS
This project supports communication with a JK BMS using a wired medium. Parameters are polled at customizable intervals and displayed in the Web UI as well as published to the MQTT broker. The main benefit is usage of the battery State of Charge (SoC) value and the battery voltage as measured by the BMS to control the Dynamic Power Limiter.
This feature was developed against a JK-B1A24S15P model. It is assumed that all JK BMS (in this series) implement the same protocol on their UART interface. The following models are listed in a manual that includes the tested model:
JK-BD6AxxS-6P / JK-BD6AxxS-8P
JK-BD6AxxS-10P / JK-BD6AxxS-15P
JK-BD6AxxS-20P / JK-B1AxxS-15P
JK-B2AxxS-15P / JK-B2AxxS-20P
Notice that buying the BMS with the CAN interface or the GPS feature might conflict with this UART interface.
See the respective documentation for details on how to connect these models.
The new-style Inverter BMS JK-PBxAxxSxxP are also supported (tested Hardware v15 and Firmware v15.10).
See the respective documentation for details on how to connect these models.
