Student-Built Electric Vehicle Sets New Land Speed Record

October 13th, 2011

A group of students from the Brigham Young University managed to set a new speed record for EVs with their electric bullet car.

The event took place on the Salt Flats of Utah, where the student-built electric vehicle was able to reach a top speed of 175mph. It would be interesting to note that the record is the ideal close for Professor Perry Carter, the leader of the group, who is retiring after spending 31 years teaching and 7 on this project.

The average speed registered by the one-seater aerodynamic car, dubbed Electric Blue, was 155.8 miles per hour, which is a new speed record for its weight class.

The wheels of the Electric Blue are enclosed so the vehicle could deter air resistance. The body is made carbon fiber and was designed using a 3D modeling wind tunnel program that helped students build a more aerodynamic car able to reach maximum speeds for its class.

In addition, the car was able to show good results thank to lithium iron phosphate batteries. The hovers of the vehicle are just an inch above the ground. It is worth mentioning that in 2010 the car created by the same team was able to reach a speed of only 139 miles per hour and the current result is definitely a win.

Nissan Working on Fast EV Charger

October 13th, 2011

Probably the biggest problems that make customers doubt electric vehicle is a low driving range and long charging time.

With this in mind the famous car-maker Nissan decided to solve one of these problems – recently the Japanese news agency Nikkei announced that the company managed to come up with an experimental system that makes it possible to fully charge an EV battery in just 10 minutes.

The technology features a capacitor in which the electrode is created using a mix of tungsten oxide and vanadium oxide that replace the conventional carbon. This considerably increases the power of the charger, allowing it to function much faster.

Nissan has carried out tests on the batteries and did not find any considerable effects concerning voltage or their storing capacity.

The new charger is about half the size of the fast charger that Nissan currently uses. It was also said that the new device will be able to charge batteries from different manufacturers. At the same time it is worth mentioning that it might take about 10 years before the EV charger hits the market.
