8. Function Introduction and Usage Instructions (Section 3 from PDF)
8.1. Active Equalization (Section 3.1 from PDF)
Figure 8.1: Active Balancing (Lossless Balancing) principle.
The protection board adopts active equalization technology. The principle of equalization is to transfer the energy of the high-voltagċellula e għall-volum baxxtage cell, achieving energy transfer through the protection board. Before using the balancing function, users need to set the basic parameters of the battery and download the JIKONG BMS-APP. After downloading, set the battery type on the parameter setting page of the APP. For default parameters, refer to Section 9. After setting the battery type, set basic battery parameters in common settings, including the number of cells, battery capacity, trigger equalization differential pressure (the default value can be retained), voltagkalibrazzjoni e, u kalibrazzjoni kurrenti.
Users can set the balance trigger pressure difference (mV) in the parameter setting of the APP. When the balance is turned on, it will be activated automatically if the pressure difference of any two strings of batteries in the battery pack is greater than the set value, and it will be turned off when the pressure difference is less than the set value. The default balance current is 2A. Users can adjust the balance current according to their own battery capacity. It is recommended that the balance current not exceed 0.2C of the battery capacity (C). If the balancing function is not needed, it can be set to off in the BMS control page of the APP.
8.2. GPS and Display Interface (Section 3.2 from PDF)
The protection board reserves a GPS port, enabling users to select a GPS device to meet battery location requirements. Additionally, a display interface is reserved, supporting JIKONG displays for convenient battery information viewing. Users can select these options based on their actual needs.
Figure 8.2: Rich interfaces available on the JIKONG BMS.
8.3. Heating Function (Section 3.3 from PDF)
The protection board supports an optional heating function. This uses a resistance heater or heating film to warm the battery at low temperatures, preventing charging and discharging issues due to reduced battery activity. The designed heating current is 20A. Users can control this function via the BMS control page in the APP based on ambient temperature. It is recommended to install a temperature control switch (45°C to 65°C normally closed type) in series with the heating circuit as a secondary protection to prevent thermal runaway.8.4. Alarm Function (Section 3.4 from PDF)
The protection board supports an optional alarm function. When the BMS detects safety risks such as overtemperature, overcharge, or overdischarge of the battery, an external alarm will be triggered.8.5. Battery Parallel Function (Section 3.5 from PDF)
The protection board supports an optional parallel function for battery packs, meeting the demand for energy storage systems. This function requires synchronous use with parallel modules, and the "disable charging current limiting" function must be turned off in the APP.
8.6. ACC Detection Function (Section 3.6 from PDF)
The protection board supports an optional ACC detection function, which can enable discharge. There are two ways to achieve this: apply voltage between ACC+ and ACC- (20V-100V), or directly short-circuit ACC+ and ACC-. Additionally, a charger detection function is reserved via C_detect+ and C_detect- interfaces for enabling charging.8.7. Charge Overvoltage Protection and Recovery (Section 3.7 from PDF)
The protection board is equipped with standard charge overvoltage protection. Users can set single overcharge protection voltage and recovery voltage in the APP. If any cell voltage exceeds the set protection voltage, the BMS will stop charging. Charging resumes when all cell voltages drop below the recovery voltage.8.8. Discharge Undervoltage Protection and Recovery (Section 3.8 from PDF)
Standard discharge undervoltage protection is included. Users can set undervoltage protezzjoni voltage, recovery voltage, and automatic shutdown voltage in the APP. If any cell voltage jaqa taħt il-protezzjoni voltage during discharge, the BMS will stop discharging. Discharge resumes when all cell voltages rise above the recovery voltage. If any cell voltage falls below the automatic shutdown voltage, the BMS will automatically shut down.8.9. Charge Overcurrent Protection and Recovery (Section 3.9 from PDF)
Standard charge overcurrent protection is provided. Users can set continuous charging current, overcurrent delay, and recovery time in the APP. If the charging current exceeds the set limit for the specified delay, charging will stop. Charging resumes after the recovery time.8.10. Discharge Overcurrent Protection and Recovery (Section 3.10 from PDF)
Standard discharge overcurrent protection is provided. Users can set continuous discharge current, overcurrent delay, and recovery time in the APP. If the discharge current exceeds the set limit for the specified delay, discharging will stop. Discharging resumes after the recovery time. Note: The maximum continuous discharge current cannot exceed the design value of 300A.
8.11. Overtemperature Protection and Recovery (Section 3.11 from PDF)
Standard charge and discharge overtemperature protection is included. Users can set protection and recovery temperatures in the APP. If the temperature exceeds the set limit, charging or discharging will stop. Operation resumes when the temperature returns to a safe level.8.12. Low Temperature Protection and Recovery (Section 3.12 from PDF)
Standard charge low temperature protection is included. Users can set protection and recovery temperatures in the APP. If the temperature falls below the set limit, charging will stop. Charging resumes when the temperature rises above the recovery level. In extremely cold areas, using the optional heating function is recommended.8.13. Short Circuit Protection and Recovery (Section 3.13 from PDF)
Standard short circuit protection is included. Users can set short circuit protection delay (µs) and recovery time (S) in the APP. If a short circuit occurs during initial charging or connecting a load, the delay can be adjusted to prevent false triggers due to peak currents. The BMS will resume operation after the recovery time.8.14. Emergency Switch (Section 3.14 from PDF)
The BMS includes a standard emergency switch function. If issues like over-temperature, over-discharge, over-charge, or cell drop occur, activating the emergency switch in the APP will enable charge and discharge for 30 minutes, providing emergency use time. The protection board will continue to operate until the 30-minute cycle ends, even if cell voltage reaches automatic shutdown levels.8.15. Intelligent Sleep (Section 3.15 from PDF)
The BMS features a standard intelligent sleep function. Users can enable or disable this in the APP. This function closes the protection board when it's in standby (charging and discharging current less than 1A for 26 consecutive hours) to reduce energy consumption. It can be reactivated by pressing a button or connecting a charger.8.16. Communication Function (Section 3.16 from PDF)
The protection board supports optional CAN and RS485 functions. Users can select these based on their needs and set the address and communication protocol in the APP. Refer to the JIKONG Protection Board communication protocol document for specific details.
