ultra capacitor

The government of Hong Kong is ready to invest $180 million to acquire 36 single-decker buses, but ordinary coaches won't cut it. Ordinary emissions buses, that is. Concerns over roadside pollution have convinced government officials in Hong Kong to purchase eight low-emissions "supercapacitor" ...

In the realm of vehicle electrification, EEStor and its super-duper ultra-capacitors are roughly the equivalent of Duke Nukem Forever for video game players. The creators of both products have made impressive claims and repeatedly promised public demonstrations and introductions for many years. ...

We recently learned from BMW that it was working on a hydrogen hybrid powertrain that was being tested in a modified front wheel drive 1 series. The announcement was buried in a lengthy press release about the ...

According to reports from Reuters and GM-Volt.com, Zenn Motors has canceled plans to launch its cityZENN high-speed electric car and will slow down work on its low-speed EVs. According to Zenn Chief Executive Ian Clifford, the company will focus its efforts on becoming a supplier of ZENNergy ...

Kia is reportedly considering the use of ultra-capacitors to store electrical energy in the next generation version of its fuel cell vehicle. Ultra caps have an advantage over batteries in that they can absorb and release energy much more quickly. Unfortunately, they don't have as much capacity and ...

While batteries make most of the headlines when it comes to the energy storage requirements of electric cars, the capacitor could be an exciting and viable alternative. Unlike batteries, which store chemical energy and make it available for use as electrical energy, capacitors store energy in the ...

The most important part of an electric or hybrid vehicle is often said to be the battery. With all the breakthroughs in energy storage and the emergence of new companies, it can be a difficult field to keep up with. If you are a potential investor or just a curious onlooker you might be interested ...

Researchers at North Carolina State University have developed a new type of capacitor which allows up to seven times the electrical storage potential as standard capacitors available today. The breakthrough apparently is a polymer called PVDF which can act as a high-performance dielectric, which is ...

Automotive DesignLine reports on a hybrid bus design by ISE Corporation which incorporates ultra capacitors. What are these ultra capacitors, and why are they needed in a hybrid vehicle? Regenerative braking, the key to the increase in fuel economy of hybrids, allows a vehicle to recapture and ...
