Maxwell introduces higher-voltage ultracapacitor cell

Maxwell Technologies has introduced a new addition to its K2 family of ultracapacitor cells. A 3-volt, 3,000-farad cell is now available in sample quantities. The new cell offers 31% higher power than Maxwell’s existing 2.7-volt, 3,000-farad cell, and is packaged in the same industry-standard 60 mm cylindrical form factor. Maxwell points out that customers can… Read more »

2016 Cadillacs to use Maxwell ultracapacitors in start-stop system

Start-stop vehicles (SSVs, if you will) occupy the bottom rung of the electrification ladder, and they’re growing in importance as global OEMs search for ways to meet tightening emissions standards (anything other than selling EVs, it sometimes seems). Over 40 percent of new cars sold in Europe already incorporate start-stop technology. A battery-based start-stop system… Read more »

Maxwell Technologies introduces 24-volt versions of ultracapacitor-based Engine Start Module

As every truck driver or heavy equipment operator knows, diesel engines can be difficult to start in low temperatures, or after not being started for long periods. Maxwell Technologies’ Engine Start Module (ESM) is an ultracapacitor-based system that takes over the engine cranking function and remains fully charged, even if battery voltage drops. Now Maxwell… Read more »

USABC awards funding for stop-start applications, improved electrolytes

The US Advanced Battery Consortium (USABC) has awarded $2.68 million to San Diego-based Maxwell Technologies for the development of a hybrid energy storage system for automotive stop-start applications. The competitively bid contract award is co-funded by the DOE. The 19-month program will focus on the technological and economic feasibility of adapting a 12-volt hybrid energy… Read more »

Maxwell and Corning agree to work together on ultracapacitor tech

Maxwell Technologies (NASDAQ: MXWL) has announced a joint development agreement with Corning (NYSE: GLW) with the goal of advancing the state of capacitive energy storage technology. Maxwell brings expertise in ultracapacitor cell design and a growing presence in the energy storage market to the partnership, while Corning is a specialist in high-performance materials, and has… Read more »

Ultracapacitors supercharge stop/start systems

Electrification is quietly sneaking into “conventional” vehicles, as more models incorporate stop/start technology. Navigant Research predicts that 54% of new vehicles worldwide will have stop/start capability by 2022. Different automakers are applying stop/start in very different ways. For energy storage, a stop/start system may use Li-ion batteries, advanced-glass-mat (AGM) lead-acid batteries, ultracapacitors (UCs), or some… Read more »

Maxwell’s new ultracaps increase shock and vibration tolerance, a big advantage in mass transit applications

Maxwell Technologies’ new DuraBlue ultracapacitor cells incorporate a number of upgrades over previous versions. The 2.85-volt, 3400-farad cells offer up to 1,000,000 duty cycles, with up to 18 kW/kg of specific power and up to 4.00 Wh of stored energy. They use the industry-standard 60 mm cylindrical K2 form factor, and are available with threaded… Read more »

Maxwell and SK to jointly develop ultracap/battery combo

Ultracapacitors (aka ultracaps or supercapacitors) are the toast of the town, thanks to their rapid charge and discharge capabilities, tolerance of extreme temperature conditions and long operational life. However, their killer application may be as partners with lithium-ion batteries, which offer higher energy density. Maxwell Technologies (Nasdaq: MXWL), a manufacturer of ultracapacitor-based energy storage products,… Read more »

Ultracapacitors creep into automotive

Maxwell looks to leverage its early ultracapacitor experience into a ubiquitous, low-cost, high-volume complement to batteries. Power sources like internal combustion engines and advanced battery packs work great as continuous suppliers of energy. But during the highest peak loads, both sacrifice efficiency attempting to meet the power delivery demands. And pushing these devices to their… Read more »
