SmartGen HBCU200 Battery Management System Master Control Module

* All prices on this website are retail in USD on EXW incoterms


HBCU200 Master Control Module is a significant part of the energy storage battery manage system (BMS), which can manage the battery system safely, realiably and efficiently. HBCU200 collects the voltage and temperature of the single cell of the battery module uploaded by BMU slave control module (supporting lithium iron phosphate and ternary lithium) to calculate SOC, SOH, the max. single cell voltage/temperature, the min. single cell voltage/temperature, insulation resistance and other data. It realizes the protections of over/under voltage, high/low temperature, charge/discharge overcurrent of the cell by the tertiary fault protection system and the control of external main circuit relay. HBCU200 is compatible with protocol by PCS of different manufaturers to realize charge/discharge management of battery cluster.


1. Rated operating voltage is 12/24VDC;
2. LED lamps indicate the running status and alarm status of the module;
3. It can collect total voltage and current of battery cluster and calculate the SOC and SOH data;
4. It can collect the insulation resistance to the ground for the positive and negative of the battery cluster;
5. Collect the current of battery cluster by Hall current sensor or diverter;
6. Receive the voltage and temperature of a single cell of BMU module via non-isolated CAN port, and calculate max./min. voltage of battery cell, control passive balance on BMU module. This port can also be used to upgrade BCU firmware program.
7. Tertiary fault alarm protection function, which can alarm for over/under voltage, high/low temperature, charging/discharging overcurrent, low insulation resistance, abnormal communication, high voltage collecting fault, current collecting fault, cell voltage collecting fault, temperature collecting fault. The alarm protection actions can be set as level-1 current drop (drop to 50%), level-2 current drop (drop to 80%), level-3 current drop (drop to 100%) and high voltage power-off;
8. 2 isolated RS485 communication ports using Modbus protocol, which can communicate with HMU8-BMS display module and PCS;
9. 1 ETHERNET port to monitor BCU data;
10. Bluetooth function can monitor BCU data by mobile APP;
11. 7 relay output ports, of which 5 are active output ports (the default function is master positive relay output, pre-charge output, module power control, alarm indicator output, operation output), the other 2 are passive output ports;
12. 4 input ports, of which 3 are aux. input ports, 1 is fixed as adhesion detection input of master positive relay;
13. With 1 temperature sensor, NTC 10K-3950 type can be connected;
14. With event-log, which can circularly record 200 items of historical records (contents and detailed data of tertiary fault alarm);
15. Daily, total charging/discharging energy (kWh) and battery capacity (Ah) data can be counted;
16. Modular design, screw-mounting, flame retardant ABS/PC shell with compact structure and easy installation.
17. The built-in SD card storage function can support up to 32GB data (depends on customer’s needs).
