First never believe anything Pike says as they are mostly wrong. Not sure who is paying them off or if they are just incompendent. Likely getting paid to give a customers viewpoint/bias.
Next as an EV designer, builder and driver one should never design a larger battery pack without cooling. Cars get 60C just sitting in the summer sun turned off. Just ask anyone in the south.
EV's shouldn't have more than 100-150 mile range as after that a ICE generator is far more cost effective and gives unlimited range. All my EV's have or will have a 40lb generator giving unlimitede range. 80 mile range is probably the sweet spot.
A123's have so little resistance they put out huge amounts if specific power with little heat generation. I agree this is just a small improvement mostly gained by higher battery weight/kwhr. This means more material though as they said, Iron, alum, Lithium, plastic, etc is cheap with most under $4/lb and averaging about $6/lb. Most Lithium batts are about 22 lbs so it's just not that costly.
I buy complete A123 battery pack systems/BMS, etc for about $700/kwhr custom made from cylinder cells that can and has done 170mph and 7.9sec 1/4 mile though that was recently broken to 200mph and 6.9sec EV IIRC.
Beth, you are right there. Time is an issue. It takes time to prove a technology does in practice what it does in the lab. I think they have something here, and it is a good trend. Let's see if investors think so too.
On paper, or maybe even in limited testing, it seems like A123 has made a big leap with its lithium-ion cells in terms of reducing cooling requirements. Nevertheless, there is still a lot of skepticism that the company will have to over come. Commercializing these efforts will take a lot of time and money, which is something A123 and its battery maker competitors don't necessarily have.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
