Orion Expandable BMS: Next-Level Battery Management for Advanced Applications

Experience the future of battery management with the Orion Expandable BMS, a groundbreaking system that promises unparalleled flexibility and safety.

Product Description:
The Orion ExpandableBMS (Battery Management System) is a state-of-the-art battery management solution designed to meet the advanced requirements of contemporary energy storage applications. Engineered for precision, reliability, and adaptability, this system ensures the optimal health, safety, and longevity of your battery packs.  The Remote BMS must be coupled with the Remote BMS (REM) BMS It is not compatible with the Orion O2 Standard BMS.

Key Differences Between Orion Expandable BMS and Standard Orion O2 Controller.

1. Split Pack Configuration:

  • Orion Expandable BMS: Offers the unique capability to split the battery pack and manage it with separate BMS controllers. This design ensures better isolation between sections, thereby enhancing the overall safety and integrity of the system.
  • Standard Orion O2 Controller: Operates as a singular unit, managing the battery as one connected system without the split-pack feature.

2. Enhanced Configurability:
With the Orion Expandable BMS, users are endowed with advanced configuration options. This permits tailored setups, catering to specific needs and applications, ensuring optimal performance and longer battery lifespan.

3. Superior Isolation:
The split-pack approach of the Orion Expandable BMS grants enhanced protection. By isolating different sections of the battery pack, potential issues in one section can be contained, reducing the risk of a wider system failure.

4. Intuitive User Experience:
Despite its advanced features, the Orion Expandable BMS is user-friendly, with a clear interface, intuitive controls, and detailed analytics. This makes it easy even for novices to understand the intricacies of their battery systems and make informed decisions.

Perfect for large-scale energy storage solutions, critical backup systems, electric vehicles, and any setup that requires advanced battery management with an emphasis on safety and configurability.

Choosing the Orion Expandable BMS is not just an upgrade; it's a leap into the future of battery management. Whether you need enhanced safety, advanced configuration options, or simply a more reliable and effective system, the Orion Expandable BMS stands out as the paramount choice.

General Orion BMS O2 Description:
This second generation of the Orion BMS improves on many aspects of the original, delivering significantly more functionality and capabilities while reducing size and weight. Orion Battery Management Systems from Ewert Energy Systems are robust, full-featured BMSs that are specifically designed to handle the rigors of on-road and off-road automotive use. They provide both digital and analog outputs to control chargers, motor controllers, and other external devices like cooling fans or heaters. Orion BMSs are field programmable with two CAN interfaces and OBD-II support for retrieving data logs, trouble codes, or snapshots as faults occur in the field with OBD-II scan tools.

Highlights of New Features of the New Orion BMS are:
1. Significantly smaller size for 24 cell to 72 cell models due to a new enclosure size that was introduced.
2. Roughly 40% lower weight on all models due to the new enclosure design and streamlined heatsink. Additionally, the heatsink is now removable (minimum heat dissipation requirements still apply).
3. Direct hardware support for several popular charging protocols including SAE J1772 (directly interfacing with the pilot/ proximity lines)
4. Significant algorithm and software improvements to improve overall system accuracy for parameters such as the State of Charge and pack health.
5. Wider input power voltage range (now 12v-24vDC compatible) for better support on heavy vehicles and equipment. The Orion 02 remains fully compatible with 12v applications.

The Orion BMS protects and monitors almost all Li-Ion battery packs for both Electric and Hybrid vehicles by providing:
•Thermal Management
•Current and Voltage Protection
•Smart Cell Balancing and State of Charge via Coulomb Counting
•Internal Resistance Data Advance
•Isolation Fault Detection

The Orion BMS also has some very useful add on accessories that can save you time and money while programming or in the field:

SOC Display with Data Logging -- Connects to the BMS via CAN providing parameters to a memory card at a user-designated frequency from 100mS to 10 seconds
Cell Wiring Validator -- Checks the cell tap wiring harnesses to ensure they are wired properly before plugging them into the system.
Thermistor Expansion Module -- Allows up to 80 additional thermistors to the system via CAN. If needed, up to 10 Thermistor Expansion Modules can be used together allowing up to 800 thermistors to be used in a system.
Orion BMS Connect -- An internet-based remote monitoring system that allows the user to monitor battery packs via PC/MAC, smartphone, or tablet. It provides instant data, charts of recent history, and diagnostic information including recent events, fault codes, and freeze frame data all on a webpage!
