Note: The new version has cancelled the RS485 reserved interface and does not support RS485 function.
Features:
1. Smart Battery Management: The JK-B2A8S20P Smart BMS is designed to provide advanced management and protection for 4S-8S Li-ion and LiFePO4 batteries, ensuring their safety and optimal performance.
2. High Continuous Current: With a robust continuous current rating of 200A, this BMS can handle high-power applications with ease, making it suitable for various industrial and DIY projects.
3. Active Balancing: The active balancing feature with a 2A balancing current ensures that the voltage across individual battery cells remains uniform. This helps extend the lifespan of the batteries and maximizes their capacity.
4. Heat Function: This BMS also includes a heat function, which helps monitor and manage the temperature of the battery pack, further enhancing safety during operation.
5. Versatile Compatibility: Compatible with both Li-ion and LiFePO4 batteries and supporting voltage configurations of 12V and 24V, this BMS offers versatility and flexibility for a wide range of applications.
NOTICE:Protection (Current Sensor Anomaly)This problem exists when the inverter is used, because the current direction is uncertain, The alarm will be displayed. It does not affect the normal use of BMS.This kind of alarm will appear when the sun is not big or small, because at this time, the battery fluctuates frequently between charging and discharging, and there are uncertain factors, so this problem occurs.A pure sine wave inverter does not draw a constant current. The current from the battery follows a sine wave shape.It ramps from zero current up to peak current in 1/4 of a cycle.The peak current is actually about 40% more than the average current.Then the current will ramp back down to zero at the 1/2 cycle time. At this point, the inverter reverses polarity, and ramps the current back up again, hitting the peak at the 3/4 cycle time. The battery current is positive again, and the inversion happens in the inverter circuit. The the current ramps down back to zero again at the end of the cycle.The process them repeats for every cycle.If you measure with an averaging meter, you will just see a fairly steady current that should be close to the true RMS current.I use a True RMS Fluke meter, and it is able to give a vey accurate reading on this odd waveform.The current reading in the BMS just measures the voltage across a shunt resistor. This reading is only taken periodically,and it is not synced the the changing current from the inverter. It might take a reading at zero current, or at the peak current, but most likely, it will fall somewhere in between.Due to the shape of wave, the reading tends to a bit above and below the true RMS current.It is not perfect, but over the long term, it is "good enough" for the BMS to calculate the amp hours charged in or discharged out of the battery.This because if you average the readings over a full hour, the high and low readings will average out.
