Intellectual Property

Exergonix has developed an extensive portfolio of intellectual property behinds its product line. The advanced Battery Management System (BMS) hardware platform can be used for either traction/automotive or stationary applications in a multitude of applications. Firmware and software has been fully developed and validated for use in production environments in both markets and applications. The BMS hardware platform is a chemistry agnostic, automotive grade electronic control module (ECM) and the hardware has been subjected to rigorous analysis, review and 3rd party testing to complete PPAP qualification as an automotive component, including:

  • Electrical stress tests – High voltage isolation, over/under/reverse voltage
  • Environmental tests – thermal extremes, thermal shock, humidity, spray & immersion
  • Conducted and radiated EMI/RFI tests
  • Mechanical stress – vibration, shock
  • DFMEA – BMS & battery system

The BMS is a distributed control system consisting of a central BMU providing high level system integration and communication functions and distributed LMUs which monitor cell voltage and temperature, and perform cell balancing missions. There are several instances where the BMU has been repurposed to serve as a dedicated ECM, an intelligent Gateway, or other embedded controller to facilitate complex system integration. As part of the UL 1973 Listing, risk analysis, architecture partitioning and a comprehensive safety review pursuant to UL 1998 was performed and passed.

The BMS features:

  • Cell Balancing – Auto-adjusting, real-time cell balancing algorithm that maximizes available system capacity
  • Dynamic Capacity Adjustment – Ability to dynamically adjust demand reduction target while protecting system capacity
  • Self-Diagnostics – Embedded Self-Diagnostic circuitry and firmware for real time measurement verification
  • State of Health algorithm to characterize individual cells in the battery system
  • Life-Cycle Management - Dynamic processing of system real-time data to equalize aging effects within battery pack

Additionally, the Exergonix/CODA proprietary thermal management technology is a closed systems that optimize efficiency through thermal balancing and distribution via container partitioning and controlled heat flow. This designs effective management of heat generation is based on thermal gradients through controlled heat flow and cooling methodologies. When coupled with power management efficiencies developed by the company to limit and maintain runaway power within the enclosures, the product is optimized to creates a safe operating envelope.

Exergonix/CODA is unique in the development, manufacturing, installation and operation of UL 1973 Listed, behind-the-meter, C&I energy storage systems and an array of IP and knowhow, along with process trade secrets are well managed within its portfolio of the company.

The CODA CORE™ Single Tower Power Controller (STPC) and Multi Tower Power Controllers (MTPC) manage the distribute load for sites. Depending on where more than one tower is deployed, this unique control can provide self-managed power as loads are seen within the performance algorithm. The currently operating systems employ STPC and MTPC to optimize the power distribution on deployed storage systems. The company owns and operates ESS using its own power management software and firmware as self-generating units, with a history demonstrated in the California SGIP, AQMD 135 and AQMD 922 deployment programs. The STPC is the site controller for most behind-the-meter C&I ESS. The power controllers are based on an industrial PC platform using Windows and a proprietary BMU based gateway module (BMU GWM). In a typical installation, the STPC/MTPC operates autonomously to monitor building power flow via its meter interface (Modbus or Zigbee) and responds by reducing peaks according to its site configuration and embedded peak-shaving algorithm. The STPC/MTPC also logs and communicates system data and operating/diagnostic status to central data base (via cellular or customer hosted networks).

The company’s in-house performance algorithm was developed to support system hardware configuration (flag array matching system software and hardware features, integrated components & communication requirements). Seasonal predictive adjustment are made at the start of every billing month based on long term historical data for the site and annual retroactive adjustment are made to better match the observed performance.

Selling & Installation Tools - Building characterization parameter for systems to monitor & collect data regarding installation site energy usage and apply simulated peak shave algorithm for the purpose of evaluating projected savings from site is critical. Exergonix/CODA intellectual property in the area of power monitoring is a key to its successful implemention of ESS. In addition, commissioning tools to support automated system commissioning have been developed. These tool run standardized checks on system communication and controls and generates Field Installation Exit Reports.
