INTELLIGENT ENERGY CONTROL

Advanced Battery Management Solutions

High-performance battery management systems for industrial and energy storage applications.

AI-generated board — not an IEC product

Headquartered in Austin, Texas, IEC develops battery management solutions for customers worldwide.

Safety, intelligence, and sustainability guide our research and innovation in battery management technology. We combine U.S.-based manufacturing and quality assurance with a global service network.

From individual cell management to energy dispatch, our end-to-end capabilities help customers improve energy efficiency and support long-term sustainability.

Slave BMS Module (BMM)

Slave BMS Module (BMM)

Monitors cell voltage and temperature in real time, manages active or passive balancing and cell temperature, and communicates with the upper-level controller via CAN or isoSPI.

  • Supports 12–112 strings
  • Pin-to-pin compatibility
  • Passive balancing: 100 mA
  • Active balancing: 2 A
Master BMS Module (BCM)

Master BMS Module (BCM)

Monitors voltage, current, and temperature at the rack level. Calculates state of charge (SOC), state of health (SOH), and other battery states, executes balancing strategies, diagnoses faults, and provides local protection.

  • Fault detection and circuit cut-off protection at alarm thresholds
  • Active thermal management and control
  • CAN, RS-485, and Ethernet communication
  • Bootloader upgrades
Display Control Module (ESMU)

Display Control Module (ESMU)

Brings battery system data and fault diagnostics together in one display. Activates alarms and protection functions based on battery status and stores local system data.

  • ARM processor, 4G RAM, 16G eMMC
  • IEC61850, MODBUS, MQTT IoT, and other protocols
  • LAN, RS485, CAN, and DI/DO
  • SDK development and over-the-air (OTA) updates
  • Full life cycle data storage
High Voltage Box (ESHVB)

High Voltage Box (ESHVB)

Manages the battery rack’s high-voltage power circuit, including contactor control, protection, and data communication. The BCM can be housed inside the unit.

  • Integrates circuit breakers, contactors, fuses, circulating current control circuits, current sensors, secondary BMS (ESBCM), and switching power supplies
  • Rack-level control, protection, and data communication
  • Customizable to project requirements
IEC energy storage cabinet
IEC energy storage cabinet

Liquid-Cooled Energy Storage Cabinet

  • Deploy the IEC cabinet as a standalone system, integrate it with solar photovoltaics and energy storage (PV + ESS), or use it in a microgrid and other energy storage applications.
  • Connect it to IEC’s centralized energy management platform for real-time monitoring, energy optimization, peak shaving, valley filling, and demand response.
