9/26/2014 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 combination thereof.

9/23/2014 Maxwell, Win Inertia bet on ultracapacitors to store energy

Although082014heather-inline-2 they look a lot like batteries, ultracapacitors can be charged and discharged far more quickly, making them attractive for applications that require rapid bursts or occasional boosts of power. Primarily that’s because they rely on electrostatics, and not a chemical reaction, to perform.

9/22/2014 Stop Accepting Underperforming Start-Stop Systems

What does the ultracapacitor do better than anything else? Provide short-term high power for many, many cycles. There are not many applications better suited for that capability than engine cranking in a start-stop vehicle.

9/19/2014 STOP-START SYSTEMS DRAIN BATTERIES

Here’s something we’ll bet your were not aware of before. The battery in your car will typically last five to eight years, but not if your car has a stop-start system. That will wear the battery out in one-and-a-half to two years. That’s according to a supplier company called Maxwell Technologies that makes ultracapacitors. It says that if you combine an ultracapacitor with a conventional lead acid battery, they will last 100,000 miles or over 160,000 kilometers. This set up is already available in Europe via the supplier Continental and is available on a number of Peugeots and Citroens. And we think this technology could spread wide and far throughout the auto industry.

9/18/2014 Stop/Start Problems Could Put Charge Into Ultracapacitor Market

Ultracaps, long considered too costly for widespread employment in light vehicles, appear to be gaining traction – albeit ever so slowly – as electrification takes hold and automakers find the technology’s advantages harder to resist, leading supplier Maxwell Technologies contends.

9/18/2014 Transforming the Transportation Industry with Renewable Energy

When you think of green energy, are solar and wind power the first things that come to mind? Perhaps you think of hydropower, geothermal or biofuels instead. While regenerative braking has steadily gained traction in terms of adoption, the average person probably does not even rank it in the top 10 of green energy approaches, nor are most people likely to immediately think about green energy in mass transportation, a notoriously energy-intensive industry. However, regenerative braking in transportation is a renewable energy solution that helps make the world a bit greener and deserves greater attention for the benefits it can deliver.

8/28/2014 Maxwell launches electronic voltage transformer for smart grid applications

Maxwell Technologies has introduced new electronic voltage transformer (EVT) for smart grid applications, which range from 110kV to 550kV. The latest addition to Maxwell's CONDIS family of high-voltage capacitors and capacitive dividers, the EVT can be used for digital current and voltage monitoring in smart grids to ensure grid measurement accuracy due to its low voltage output and high temperature stability.

8/25/2014 Braking energy recuperation in Spanish rail system

Braking energy recuperation systems in electric and hybrid rail vehicles save fuel and electrical energy by using resistance from the electric motor to stop the vehicle, and, through that process, converting kinetic energy that would be wasted in a conventional friction-based braking system into stored electrical energy. Ultracapacitors' high reliability and extremely long operational life also make them a preferred option for heavy cycling electric utility grid applications.

8/21/2014 How to Kill an Ultracapacitor, if You Really Want To

When working within their specified operating parameters, ultracapacitors will provide a stubbornly long and trouble-free existence. Ultracapacitors will outlast most other electronic components in any given application, which is why they are the perfect power delivery device in the most demanding environments.

8/20/2014 Maxwell, Win Inertia bet on ultracapacitors to store energy

Although they look a lot like batteries, ultracapacitors can be charged and discharged far more quickly, making them attractive for applications that require rapid bursts or occasional boosts of power. Primarily that's because they rely on electrostatics, and not a chemical reaction, to perform. It's not uncommon to find them in hybrid buses (especially in China), where they help boost fuel efficiency by providing propulsion for acceleration, or paired with batteries (which can store more power) and used to harvest and store energy from wind turbines or solar panels.
