  • Extends Battery Life – Communicates with power conversion systems to deliver optimal charge cycling
  • Ensures Battery Safety – Identifies cells that need servicing or replacement or are being operated outside manufacturer specifications. Initiates preventive action to protect the battery and ensure safe operation
  • Balances Cells – Provides passive balancing for lithium-ion and other battery chemistries
  • Browser-Based User Interface – Platform agnostic (Windows®, Linux®, iOS®, mobile) operator interface allows user to view system performance, take down or bring up stack(s), view faults and warnings, update BMS firmware
  • Highly Configurable – Over 1000 configuration settings deliver highly optimized battery performance on a wide range of battery platforms, and enable custom-tuning of the BMS for target applications
  • Customizable – Nuvation can add client-specific support and functionality to the BMS to deliver additional features without additional hardware
  • Built-In Wireless Support – Coming soon: Optional built-in Wi-Fi and Bluetooth support, no external modules required

MESA Conformance

Mesa.jpgNuvation BMS™ is conformant with the MESA-Device/Sunspec Energy Storage Model. MESA (mesastandards.org) conformant products share a common communications interface that exposes all the data and control points required for operating an energy storage system. This enables Nuvation BMS™ to be integrated with other MESA-conformant energy storage hardware or software without the need for custom middleware.
