Real-Time Battery Chemistry Modeling Delivers Transformative Performance Results

Battery Chemistry

A battery, at its core, is a device that creates electric output from chemical reactions. The efficiency of harnessing the electricity depends on the chemistry involved. It also depends on the design, manufacturing, assembly, and use of the battery. Furthermore, the age of the battery and the environment that it is operating in also influence battery productivity. Even though all of these factors affect battery performance, the most important metric to understand is the real-time state of the electrochemical reaction, because, ultimately, this is the source of the desired output – energy. Better visibility and data from this interaction opens opportunities for improved efficiency and much more. 

 

Traditional Battery Management System Shortfalls

Despite the importance of needing to understand more about the electrochemical reaction, present-day battery management systems (“BMS”) do not monitor and track electrochemical reactions occurring within batteries. They monitor current, voltage and temperature, and toggle the charging based on these values. However, these metrics are products of the electrochemical reactions, not analytics from the actual chemistry unfolding within the cells. Since these BMS are not able to provide real-time data, much less analytics, and certainly not control of the electrochemical reactions, they are operating on a reactive basis and not addressing the root issues at the moment they occur. 

 

To maximize the reactions occurring, an ideal BMS would be able to collect, process, analyze and respond to analytics on the electrochemical state of the battery cells in real-time through automation, without any need for external interaction. This level of direct real-time feedback would allow for instant reaction in response to the dynamic changes at the battery cell level. Interacting directly with the chemistry in real-time would allow for a BMS to modulate the dis/charge cycles with precision, based on what is actually happening in the electrochemical environment rather than secondary parameters that hit thresholds (e.g. temperature becomes too hot or voltage exceeds a certain level).

 

3DFS Advantage

3DFS has leveraged a proprietary, real-time computing system, Task Oriented Optimal Computing (“T2C”) and developed a new, transformative method of modelling and controlling batteries to sense and respond to the electrochemical reactions within the battery in real-time. The SineSync BMS delivers and acts on precision feedback related to the electrochemical state of each battery at all times allowing the individual battery performance curves to be clearly defined so that the batteries can be pushed to the absolute maximum that chemistry and physics will allow. 

 

SineSync BMS Delivers Unprecedented Features in Energy Storage World

Using real-time chemistry analysis, the SineSync BMS delivers both universal performance improvements and advanced functionality relative to the existing control method, which relies on current, voltage and temperature. 

 

At the battery level, the SineSync BMS creates an electronic layer that separates the battery cell from the outside world. This electronic layer directly interacts with the cell and its function is to sense and analyze the intense chemistry within the battery cell. Once a battery has the electronic layer adhered to it, it will be a Software-Defined Electricity (“SDE”) battery. From that point forward, its energy output will be as efficient as the original design allows it to be. 

 

SineSync BMS is chemistry agnostic and has already been applied to lithium-ion and lead acid chemistries. In each of these applications, the results demonstrated a near doubling of the charge rate. The depth of dis/charge performance was stable for the full life of the battery with a near doubling of the discharge depth. In addition, the batteries did not heat up during dis/charging and were projected to deliver nearly twice the number of expected charge cycles.

 

Advantages of an SDE Battery from a product design and form factor perspective include:

  • Wider, more defined range of operating: Battery life and performance optimization reliably extends the operating parameters and stabilizes the dis/charging profile while shrinking the form factor. Clearly defined operating parameters deliver more reliable battery performance across a broader range of applications.
  • Full parallel installation: All batteries are individually controlled and fully installed within energy storage systems in parallel (as opposed to battery arrays in series). This means that individual batteries can be inserted and removed without disrupting power service or affecting other batteries within an array. 
  • Ultra-efficient energy storage and power delivery: The full system will experience less than ~2% technical losses, including all AC/DC conversion, no matter the load factor or dis/charging pattern.
  • Non-invasive installation and commissioning: All systems are installed quickly, in parallel, without any additional rewiring or construction and are seamlessly commissioned with the flip of a switch.
  • Software-Defined Electricity: All SineSync systems come with Software-Defined Electricity protecting the system and the power network where it is installed with perfectly synchronized and balanced power.

Real-time chemistry modeling can be applied to any battery or fuel cell chemistry with similar expectations as previously demonstrated performance results. Whether deployed in everyday commercial or industrial battery usage, grid level storage or the extremely high performance standards of Formula E, the same principle applies. The ability to receive real-time feedback on the chemistry in the battery operating environment delivers a clear advantage when seeking battery performance maximization, both over the short and long-term.
