Fundamentals of Supercapacitor Module Design

Join us for session 1 of 4 in Richardson RFPD's "Walk Around the Block" 20 minute webinar series, Leveraging the Benefits of Supercapacitors in Cycling, Power Backup, and Pulse Power Applications.

Date: February 25, 2021
Time: 2 PM EST (11 AM PST / 8:00 PM CET)
Duration: 0.33 hour
Presented by:


Ultracapacitors are an ideal energy storage solution for high power, low energy applications or for cyclical power cycles. The long life of capacitors compared to batteries, combined with low resistance and self-heating, make ultracapacitors the superior design choice in many cases.

However, selecting a robust and reliable cell is only the first step. There is engineering necessary to match the solution with the application. That effort can often be a barrier for a company to select ultracapacitors, even when the application is right.

UTS will provide a "how-to" approach to this engineering. The presentation will cover the steps necessary to correctly match the energy storage capacity target for the application with different ultracapacitor sizes, while keeping in mind the voltage and current limitations of the power electronics. Attendees will learn that cell capacity and series/parallel configurations provide many options and variables to achieve the best solution.

This presentation will also address other parameters typical of ultracapacitor modules. Attendees will see mechanical features that address physical sizing, weight, vibration protection, and thermal management. Finally, UTS will also cover common controls requirements, such as cell balancing and module feedback communication methods, as well as the pros and cons of these design choices
