Q&A
Q1:What is the maximum active balancing current of the JK-PB Series BMS?
The JK-PB Series BMS supports high-efficiency energy transfer active balancing with a maximum continuous current of 1A or 2A (model-dependent). This technology minimizes voltage differences between cells, ensuring optimal performance and longevity for LiFePO4 or ternary lithium batteries.
Q2: What communication interfaces does the JK-PB BMS support for inverter integration?
It supports CAN communication (default 250kbps) and dual RS485 ports. RS485-1 connects to inverters, while RS485-2 enables parallel operation of up to 16 BMS units. Addresses are set via a DIP switch for seamless scalability.
Q3: How accurate is the voltage monitoring of this BMS?
The BMS delivers industry-leading voltage sampling accuracy of ≤±3mV, ensuring precise state-of-charge calculations and reliable overcharge/over-discharge protection for enhanced safety.
Q4:Can the BMS operate in low-temperature environments?
Yes, it includes a low-temperature heating function (10A design) to maintain charging capability in cold conditions. A temperature control switch (45–65°C) is recommended as secondary protection.
Q5:How do I set up multiple BMS units in parallel?
Use the RS485-2 interface and configure unique addresses (0–15) via the DIP switch.
The host (address 0) communicates with the upper software, while slaves (addresses 1–15) sync data for centralized monitoring.
Q6:What smart features does the JK-PB BMS offer?
It supports Bluetooth mobile app control (Android/iOS), intelligent sleep mode (auto-activates after 26 hours idle), and an emergency switch for 30-minute override during faults.
