Low Voltage Integrated BMS & Protectors

Vecture’s integrated BMS solutions provide centralized management and protection for battery packs, streamlining system design, reducing wiring complexity, and handling SOC, SOH, voltage, current, temperature, and protection functions.

Supports 1S–16S (12V–100V)
Protection: overcharge, over-discharge, short-circuit, thermal
Communication: SMBus, I²C, SPI, CAN, BLE, Wi-Fi
Optional: redundant protection, MOSFET switching, sensing modules, contactor support

Vecture also offers an extensive line of battery protectors—simple cutoff devices that safeguard batteries against over-voltage, under-voltage, and over-current conditions.

High Voltage Distributed BMS

The company’s distributed BMS uses decentralized control units to independently monitor and manage individual cells or modules up to 1,500V. The modular system includes 1 Battery System Manager (BSM), up to 20 Battery Cell Managers (BCMs), and a high-voltage transducer for string voltage measurement. It is scalable for large applications such as tactical energy storage, Uninterruptible Power Supply (UPS) systems, and military mobility platforms.

Battery System Manager (BSM): The system monitors pack voltages, manages contactors and pre-charging, and communicates via CAN.

Battery Cell Manager (BCM): The system measures cell voltages and temperatures, performs passive cell balancing, and communicates with the BSM via a data link.
