Offering Three Comprehensive Solutions
Innovative Products for Every Challenge
Multiple Solutions
Off-the-Shelf, Custom, and Build-to-Print
Eberspaecher Vecture offers a comprehensive Battery Management System portfolio spanning low-voltage integrated (centralized), modular, and high-voltage distributed (decentralized) solutions. The portfolio is further complemented by a range of power electronics, including DC/DC converters, lithium chargers, and cell monitoring circuits. In addition to a wide variety of off-the-shelf solutions the company also offers custom and build-to-print products and services.
Off-the-Shelf Solutions
Our Solutions
Eberspaecher Vecture has recently launched GuardIon-IQ™ a modular BMS platform offering compact architecture, industry-leading scalability, and advanced functionality. In addition to this next-generation platform, we continue to support a portfolio of proven products that have been successfully deployed in the market for over 20 years. Whether partners require a modern, modular solution or a reliable off-the-shelf design, our engineering team helps identify the optimal solution for performance, safety, and cost.
GuardIon-IQ™ - Next Generation BMS
Designed for 12 V–1,500 V (3S–16S) systems, the platform is ideally suited for mobility, energy storage, material handling, uncrewed systems, defence, and other specialized markets.
Highlights:
- Wide voltage range without redesign
- Ultra-compact footprint (80×55×12 mm)
- Passive cell balancing
- Connector options for vertical/horizontal orientation
- Advanced safety with redundant protection
- Microprocessor-based SOC/SOH algorithms
- GUI-based configuration for rapid prototyping
- Low quiescent current: less than 10uA in shutdown
- CAN bootloader with optional BLE/Wi-Fi updates
The modular architecture enables flexible integration across a wide range of applications and supports both small- and large-scale systems. Its compact size reduces space and weight constraints, improving performance, range, and usability, while upgraded components enhance durability and efficiency. The design is compliance-ready, helping partners meet functional safety requirements.
Built around a customizable BMS Controller, GuardIon-IQ™ supports integrated, modular and distributed BMS variants and offers several options including MOSFETs, contactor drivers, protection and sensing modules, and high-voltage modules—delivering flexibility, safety, and cost-effectiveness for high performance, mission critical applications.
Low Voltage Integrated BMS & Protectors
Our Integrated BMSs are centralized solutions designed to efficiently manage and protect battery packs. The BMS controls and monitors cells or modules through a single main controller, handling a number of functions, protection, and balancing. This architecture streamlines system design, enables precise management of the entire battery pack, and reduces wiring and potential points of failure.
- Supports 1S–16S (12V–100V)
- Tracks SOC, SOH, voltage, current, and temperature
- Provides overcharge, over-discharge, short-circuit, and thermal protection
- Communication options: SMBus, I²C, SPI, CAN, BLE, Wi-Fi
- Optional features: redundant protection, MOSFET switching, sensing modules, and contactor support
We also offer a wide range of battery protectors—simple cutoff devices that disconnect the battery during over-voltage, under-voltage, or over-current faults to ensure essential safety.
High Voltage Distributed BMS
The distributed system uses decentralized control units to independently monitor and manage individual battery cells or modules. The modular system includes 1 Battery System Manager, up to 20 Battery Cell Managers, and high voltage transducer for measuring string voltages.
The system is scalable for large, complex applications such as energy storage, UPS, mobility, and industrial systems.
Battery System Manager:
- Monitors pack voltages
- Manages contactors and pre-charging
- Communicates via CAN
Battery Cell Manager:
- Measures cell voltages and temperatures
- Performs passive cell balancing
- Communicates with the BSM via data link
