Using Lithium-Ion Batteries for Large-Scale Energy Storage

With the increasing expansion of capturing energy from near inexhaustible sources such as the sun and wind, a need for much greater storage capacity will naturally follow. The preferred option for meeting this challenge is using lithium-ion (Li-ion) batteries for large-scale energy storage.

Why is Large-Scale Energy Storage Necessary?

In the U.S., all end users or consumers receive power from a generation, transmission, and distribution network known as the national energy grid. The grid is a complex structure that includes utilities, individual power producers, and other non-utility energy generators. The conventional operation mode of the grid is that all generation is used or lost in either transport or conversion through the system, which works well for traditional sources such as oil & gas, coal, hydroelectric, and nuclear.

However, environmental and other concerns have resulted in a significant increase in the interest and utilization of renewable energy, especially for residential markets. But many of these sources are intermittent, and a means of storing generated energy until it’s needed is necessary. Large-scale energy storage such as this has distinct advantages, as shown below.

Advantages of a Large-Scale Energy Storage System

  • Enables more reliance on renewable energy sources
  • Improves energy system resilience
  • Makes the grid system safer
  • Promotes a more effective preventive maintenance regimen

Obviously, large-scale storage makes the grid a more robust system. Having energy in reserve to mitigate challenges such as demand changes, outages, and other service interruptions brings the grid closer to achieving its goal of delivering quality power. However, large-scale energy storage presents its own set of unique challenges.

How to Optimize Lithium-Ion Batteries for Large-Scale Energy Storage

Adapting the grid to take advantage of the availability of reserve energy from renewable sources requires a new operational perspective and model. For example, the need to transmit hundreds of kilovolts for hundreds of miles may become unnecessary with the generation, storage, and use of energy taking place locally. Irrespective of the distance from the source to the consumer, an effective method of storage is required to optimize the use of renewable energy from the grid. Today, the answer appears to be lithium-ion batteries for large-scale energy storage, which exhibit the following attributes.

These attributes, as well as scale flexibility, are reasons why Li-ion batteries are widely used in many applications, including EV battery packs. However, for high-voltage and/or power applications, battery storage system development determines how well the Li-ion battery performs. Power electronics driven by PCBAs are the drivers and controllers of Li-ion battery large-scale energy storage systems, ensuring reliable power flow at required voltage and/or current levels and accurate switching for converters and safety mechanisms.
