Ultracapacitor boasts 3,000F, low ESR in rugged design

Ioxus has announced its new iCAP™ 3,000 Farad ultracapacitor, the first size in a new family of cell products. The company says these iCAP ultracapacitors have the lowest weight, lowest equivalent series resistance (ESR), and highest power density available in the market for energy storage cells—and provide durability to support a wide array of applications in automotive, transportation, alternative energy, medical, industrial, and consumer product markets.
Among those uses are transportation drive, grid power storage, regenerative energy capture, backup power and uninterruptible power supply (UPS), ride-through, power conditioning, and renewable energy systems. Ioxus says the iCAP 3,000F ultracapacitor delivers the heaviest duty cycles and the longest life, due to minimal temperature rise.
The 3,000F ultracap is also suitable for prototype-to-production support, facilitating low ESR bus bar connections with the largest achievable contact areas. The double holes are off axis, preventing cell damage during assembly and making the Ioxus iCAP 3,000F ultracapacitor durable enough for even the toughest applications.
Among the features of the Ioxus iCAP 3,000F ultracapacitor are:
Ioxus iCAP cells are designed for high shock and vibration applications such as heavy equipment or rail. The iCAP 3,000F ultracapacitors offer a 2.7V working voltage and adhere to industry standard footprints.
Chad Hall, company founder and VP of sales, tells Automotive Designline key technology enablers for the iCAP include terminal design and packaging for a low ESR. The patent pending terminal design can accommodate three types of connections: Bus bar, laser weld, and bolt/press fit, whereas in competitive devices the terminal types only support one type of connection. The Ioxus terminal design has a large diameter for high shock and vibration resistance and better thermal transfer. Made from high-strength aluminum, the terminals can withstand higher torque, enhancing ruggedness.
As for packaging, fewer interconnects and greater contact area of the internal foils to the terminals reduce ESR (12% lower the company claims), which means lower system heating and thus cooling requirements, which Hall says is important for transportation applications.

- Largest diameter terminals
- Single terminal design for bolted or welded connection
- Lowest cell ESR
- Mil spec tumble/drop test rated

Very good product. Does it have internal current limiting protection? I also would like to know more about safety certification.

Does it mean we can then use this kind of capacitor to replace the battery in EV? If capacitor can be widely deployed, the weakness of long charging time of nowadays' EV can be ratified and it can help pushing the whole industry forward.
