Description
Inverter Smart BMS JK-PB2A16S20P (200A, 8S-16S) with active balancing
JK Smart PB2A16S20P is a next-generation intelligent battery management system (BMS) designed specifically for high-power energy storage systems and inverter integration. The board supports battery packs from 8 to 16 cells in series, providing a nominal current of 200A. It is the ideal solution for building reliable batteries for home, solar stations, or electric vehicles.
Key advantages and innovations:
• Smart integration: Full compatibility with popular inverters (Deye, Victron, Pylontech, Growatt, Must, etc.) via CAN, RS485, and RS232 interfaces.
• Powerful active balancer (2A): Unlike passive systems, JiKong BMS continuously equalizes voltage between cells, significantly extending battery life and allowing 100% capacity utilization.
• Versatility: Suitable for LiFePO4, Li-ion, and LTO cells. Optimal for packs based on EVE cells (105Ah, 280Ah, and others).
• Full control via smartphone: Built-in Bluetooth module allows parameter configuration and monitoring of each cell through a convenient app for iOS and Android.
Technical features of the model:
• Multi-level protection: Reliable algorithms prevent overcharge, deep discharge, overcurrent, and short circuits.
• Temperature monitoring: The system includes 4 external temperature sensors for cell monitoring and a separate sensor for power MOSFETs.
• Intelligent calculation: High-precision voltage and current data collection enables accurate estimation of state of charge (SOC) and state of health (SOH).
• Event log: The device memory stores up to 1000 event records with precise timestamps.
• Additional features: Port for connecting a battery heater and support for an external LCD display.
