As the price of gas increases, more and more people are choosing to buy electric cars. However, there was a serious lack of information about what happens to the large electric batteries in the case of a fire. As a result, the National Fire Protection Association (NFPA) decided to investigate the hazards faced by firefighters who put out electric vehicle fires. How are those fires different than standard gasoline vehicle fires? Can the firefighters get shocked by the big batteries? What happens when those batteries burn? How much heat energy do they put out?

Tom Bress, senior engineer at Exponent Failure Analysis Associates, conducted full-scale burn tests of electric vehicle batteries in a vehicle simulator and fire fighters put the fires out. He used LabVIEW and a NI CompactDAQ chassis to acquire data. He monitored thermocouples, heat flux sensors, and voltage and current on the simulator and on the fire hose nozzle. He also controlled the burners using a digital relay module and communicated with the propane mass flow meter using VISA and a serial cable. Most interestingly, he communicated with the batteries while they were burning using a CAN bus module in the NI CompactDAQ system. Basically, he pretended to be the onboard car computer and used the XNET protocol VIs to send and receive data from the battery. As a result, he could monitor the internal voltages and temperatures of the batteries while they were on fire. Awesome!

 

Bonus fact: Tom is also the author of Effective LabVIEW Programming, scheduled for publication by NTS Press in August of this year. Clearly, he knows his way around a block diagram.

The future is here! Last month, Hyundai released the first commercial cars powered by hydrogen fuel cells in Denmark, and Toyota and BMW are partnering to research hydrogen fuel cell technology. Benefits including high torque, zero emissions, and quick refueling make hydrogen-powered cars an attractive option for the commercial car industry, but other groups have taken an interest as well.

The Forze Hydrogen Racing Team Delft, a team of 70 students from the Delft University of Technology in the Netherlands, has developed six hydrogen-powered vehicles since its inception in 2008. The team started by first creating and racing hydrogen-powered go-karts, and in 2012 the team developed their own hydrogen fuel cell which allowed them to build the Forze V, the first-ever official competing Formula style race car powered by a hydrogen fuel cell. This year, the team is building the Forze VI, the first hydrogen powered car designed for real racing circuits.

The Forze VI is controlled by the NI CompactRIO platform and powered by a hydrogen fuel cell that generates electrical power for two electrical motors. Inside the fuel cell, which the team tests with NI CompactDAQ devices, hydrogen reacts with oxygen to produce electricity and water. Between the fuel cell and the motors, the car has an energy buffer that is used to store excess energy from the fuel cell and store recovered energy from breaking.

 

 

 

 

“The Forze VI will have around 100 kW of continuous power while the Forze V has around 15 kW,” said Tiemen Joustra, chief of embedded systems on the Forze team. “The peak power of the new car will be around 190 kW against 58 kW in the Forze V.”

 

 

Overall, the team’s goal is to promote the use of hydrogen through race cars. “We want to promote sustainability in a way that appeals to the general public, but we think hydrogen-powered road cars are reserved for the automobile industry,” said Joustra. “We would rather work towards a car for the Super Car Challenge, Le Mans, or Formula 3.”

The Forze VI is expected to hit the track for the first time in June and the team hopes it will be ready for a race near the end of summer.

Tornados are a mystery of twists and turns to many people, but the meteorological scientists at TWISTEX, are studying them every day to uncover the secrets (and data) behind this weather phenomenon.  When it came time for the team to develop a new way of collecting and recording data, they turned to NI for the hardware and software to get the job done.

 

TWISTEX is a team of scientists that measure the sound, temperature, air pressure, wind speed and direction of tornados.  Recently, they developed a sturdy, stand-alone instrument that can capture, analyze, store, and report data that is inexpensive, lightweight, and simple to use.

By using NI CompactDAQ hardware, LabVIEW, NI DIAdem, and an NI 3110 industrial controller, TWISTEX scientists created an instrument that can do everything they need and then some.  (Read about the company’s research and the instrument here.)  By using NI products, TWISTEX’s new instrument is also the first meteorological instrument that can measure audio from inside a tornado.  The data collected by the TWISTEX team is used in research to better understand and predict atmospheric conditions and severe weather patterns.

In case you weren’t able to make it to NIWeek this year, here are some of our favorite apps from the show floor.

 

Angry Eagles


This cool app consists of an Angry Birds game recreated in LabVIEW and an actual slingshot that uses NI CompactDAQ with digital and analog I/O. Users can launch the slingshot, as they would in a regular game of Angry Birds, thereby launching a bird in the game running in LabVIEW.

 

 

 

Going to the Stars With NI LabVIEW


If you never thought you’d get to travel into space, think again. Commercial space flight is on the horizon. Star Systems Inc. made an appearance on the NIWeek expo floor with its prototype spacecraft for private space flight. The system includes a PXI controller and LabVIEW to integrate all the subsystems and test engine setup.

 

 

 

Soccer-Playing Robot


One of the objectives of RoboCup is for an entire soccer team of humanoid robots to play a team of World Cup champions and win by the year 2050. Dr. Dennis Hong and his team are getting closer and closer to meeting that goal. This year, their CHARLI-L2 humanoid robot won first place in the 2011 Adult Size RoboCup Competition. Hong brought two robots, powered by LabVIEW, to NIWeek. Not only are they adorable – they are pretty good at soccer too.

My background is in writing, not so much in engineering. Ok, not at all engineering. The closest I came to engineering before working at NI was when a friend of mine made a cheesecake from Cooking for Engineers. The cheesecake was one of the best I have ever had, but I couldn't bring myself to read the copious instruction manual recipe that divulges the secrets of recreating it.

 

However, over the past three years, I have grown a fondness for engineers. My co-blogger friend, Emilie, can easily put together a LEGO Mindstorms robot, or tell me how a clock works or what in the world this is all about. She also knows more acronyms than a government lobbyist in a controversial state. And that impresses me.

 

Anyhow, I sprend a lot of time reading stories accounts case studies about what engineers are doing with NI products. Some of them, though I know are crucial to the technological advancement of this great country, I find horridly boring. I think my ignorance puts up a barrier between me and said applications (see how I did not link to any applications? Because at least I am decent at communicating, I know that doing so would be career-limiting). No, really. There are so many applications that are so far over my head that I hand them to Emilie and tell her I am not sure about them. She reads them, explains how great they are, and then I am on my merry way. Ignorance deflected, and I then have a new appreciation for something I once thought boring.

 

However, there are some case studies that are initially touching.

 

Some applications that I just can't quit reading.

 

Like this one:

 

Engineers at a University in Scotland are working with Malawi Polytechnic school to create mobile health clinics, and they've created a facility where they can actually create these mobile clinics, as well as perform routine maintainence and make sure the clinics are using enercy as efficiently and cost-effectively as possible.

 

At the remote health clinic manufacturing facility, mobile clinics or other mobile organizations can be manufactured, outfitted with appropriate interior equipment, and equipped with solar, wind, or microhydroelectric generating equipment. Currently, one remote health clinic facility is located in Makata, a small village in Malawi.

Engineering that results in deliciuos cheesecake, I get. Engineering that results in providing medical care in remote areas to those who wouldn't otherwise receive it, I also get.
