Instructions: https://github.com/JIKBMS/files/tree/main

BMS protocol: https://github.com/syssi/esphome-jk-bms

(1) Connect the protection board and battery pack according to the

following wiring diagram,Make sure that the last power cord is also

Connected to the main positive pole,The total voltage of the battery

pack must be greater than 20V(Default BMS)/10V(4S BMS) before

tarting up.

(2) Use the display activation button or additional switch to activate the

BMS.

(3) Turn on GPS and Bluetooth on your mobile phone.

(4) Make sure your mobile Bluetooth is turned on, then turn on APP

click on the top left corner of APP to search for devices, and click on

the device name to connect to the default password: 1234.

(5) Parameters need to be set for the first start-up Setting requires a

password, The default parameter is set to password 123456,Simply

set the number of units and battery type.

(6) Once the parameters are set, go back to the real-time status page,

check the battery status, no error message is prompted and normal

operation,blue is the highest voltage, red is the lowest voltage.

Interface Function Description

1. Temperature sensor interface: All models of JKBMS are equipped with

2. RS485 interface: All models of JK BMS are configured with

3. LCD interface: All models of JK BMS are equipped with

4. CAN interface: Only configurations with"CAN"in the model

5. Heating interface: Only configured with"Heat" in the model

Heating function description

1. The heating function is achieved by detect the battery temperature,combined with low

temperature protection during charging,the status of the charger to achieve electricity Poolheating control function.

2. Not all BMSs support the connection heating function, only BMSs with "Heat" in their models

support theconnectionheating function

3. The heating interface requires an externalheatingfilm or charger.

The green cable is connect to the heating film, and the red and black cables are connect to thecharger. The maximum heating power is 3A, and the maximum heating voltage is 100V

Heating on condition

1. Thebattery temperature islowerthanthelow-temperatureprotection temperaturefor charge

2. By connect the heating film for heating, the APP will activate heating, which will consume battery power.

3. Heat through the charger,this is related to the protection board hardware and charger.

Please place anorder first Confirm the technical status.

FAQ

Do not turn on

1. Ensure that the last“B+*line of the cable hasbeen connected to the

positive pole of the battery;

2. Start up after charging and ensure that the charger voltage is greater

than 4V of thebatterypackvoltage;

3. Check whether the charger has voltage output.

Inaccurate voltage

Measure the actual total pressure of the battery pack with a multimeter

and fill the actual total pressure in the "voltage calibration" on the

parameter setting page.

Inaccurate current

1. B - and P - of the protection board are two 7awg wires, both of which

need to be connected in parallel,otherwise it will lead to current error;

2. Measure the actual current of the battery pack with a clamp meter and

fill the actual current into the "current calibration" on the parameter setting

page;  the larger the actual current, the higher the calibration accuracy;

Inaccurate capacity

1. An initial capacity estimated according to the monomer voltage when

the protection board is powered on for the first time, which is inaccurate

2. After the protection board is discharged to the cut-off voltage and

then fully charged,the capacity is calibrated, and the charging process

cannot be interrupted.

The designed string number is inconsistent with the actual string

number

1. Check whether the "unit quantity" in the parameter setting is set

correctly;

2. If there is no voltage in two or more strings in the middle, check

whether the acquisition cable falls off.
