Description
Inverter Smart BMS JK-PB2A16S20P (200A, 8S-16S) with active balancing
JK Smart PB2A16S20P is a next-generation intelligent management system (BMS) designed specifically for high-power energy storage systems and operation in pair with inverters. The board supports assemblies from 8 to 16 series-connected cells, providing a nominal current of 200A. This is the ideal solution for creating reliable batteries for home, solar power plants, or electric transport.
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, the BMS from JiKong continuously equalizes voltage between cells, which significantly extends battery life and allows using its capacity at 100%.
• Versatility: Suitable for operation with LiFePO4, Li-ion, and LTO elements. Optimal for assemblies based on EVE cells (105Ah, 280Ah, and others).
• Full control from smartphone: Built-in Bluetooth module allows configuring parameters and monitoring the state of each cell via a convenient app for iOS and Android.
Technical features of the model:
• Multi-level protection: Reliable algorithms prevent overcharge, deep discharge, overcurrent, and short circuit.
• Thermal control: The system is equipped with 4 remote temperature sensors for monitoring cells and a separate sensor for power switches (MOS).
• Intelligent calculation: High-precision voltage and current data collection allows the system to accurately estimate the remaining capacity (SOC) and state of health (SOH) of the battery.
• Event log: The device memory stores up to 1000 records of operating events with precise time stamps.
• Additional capabilities: There is a port for connecting a battery heater and the possibility of installing an external information LCD screen.
