In any advanced energy storage system there is a tendency for individual cells to have different characteristics, such as energy storage capacity and discharge rates. These differences are caused by many variables, such as temperature, material impurities, surface contamination, and age. These variences can also change over the life of a cell and such changes can also vary from one cell to the next. The failure of any individual cell can cause substantial damage to the entire battery system and accompanying equipment. Therefore, monitoring an individual or group of cells is critical to preventing overcharging and overdischarging of cells.

Current battery management systems (BMS) utilize a system of voltage set-points to identify 'out of balance' groups of battery cells. With this information, operators are notified of an 'out of balance' condition or the system can choose to add power to or take power away from a certain group of cells. As energy storage systems become larger, more sophisticated management platforms need to be developed in order to maximize usage and efficiency.  Flux Power's advanced technology provides a new management methodology that doesn't simply react to inconsistent voltage conditions, but intuitively manages each cell in an advanced energy storage system.  The proprietary algorithms of the technology preemptively identify cell metrics to ensure accelerated balancing, charging and adapt the control of each cell in a battery system over time.  This feature ultimately widens the total usable energy in a given storage system while providing a significant volume of information at any given point during an individual cell's life.

Paulus Geantil, Flux Power's Director of Engineering and the inventor of this technology commented, "Less advanced energy solutions typically only monitor the charging and discharging of the batteries, by monitoring unit parameters such as voltage of the batteries, which is then recorded and analyzed by a microprocessor to determine the condition and state of each cell in the battery string. This means the system can only react to poor conditions instead of preemptively enhancing system performance. As a result, balancing can take much longer and cause delays in charge times or create systems that potentially never attain a full charge, thus sacrificing capacity."

"The market and our customers consistently request more granularity of information on the storage demands of their specific applications to maximize the efficiency of their advanced storage system applications. Our new technology will deliver that functionality to them and sets our advanced energy storage systems well ahead of anyone else in the market today," Geantil added.

The key benefit of this technology is its ability to recognize and adapt to the degradation of each cell in a battery pack through a comparative analysis of various perimeters, including the other cells within the battery pack and historical data regarding the cell. Furthermore, this technology can provide Flux's customer with real cell degradation data while being application agnostic. It will serve as a base for all of the company's advanced energy storage systems for solar, wind, back-up power, and EV (electric vehicle) applications.

"This is a key addition to our core technology as it provides our customers with one of the most robust advanced energy storage solutions available on the market today. The amount of data and the ability to monitor the changes in capacity of each cell over the cycle life will be a key differentiator in our advanced battery management systems," said Chris Anthony, CEO of Flux Power. "We are working hard to incorporate this technology into all of our future product releases in order to provide our customers with the critical data they have been requesting."
