Research on Li-ion Battery Management System in EV
and neural network

For the considerations of energy and environmental issues, the electric car has been developed fast under the joint efforts of governments and vehicle manufacturers. In all kinds of electric cars, EV has become one of the most important development directions, due to the realization of the true “zero emission”. For its energy density and excellent high voltage performance platform, Li-ion battery has become the ideal power source in EV. However, the anti-abuse capacity of Li-ion battery is poor. The safety and long-life of Li-ion battery, especially Li-ion battery pack has become urgent problems in the management of Li-ion battery use.For the current problems in Li-ion battery management, the paper studied the Li-ion battery management system in EV which was used in bus services for the Peking Olympics.The paper studied the basic working principles of the Li-ion battery at first. From the perspective of the Li-ion internal mechanism, we analyzed the factors which effect Li-ion battery performance and safety. At the same time, we did some tests about the Li-ion battery characteristics. On this basis, to the objectives of safe and effective use, Analyzed the use in vehicle and working environment for Li-ion battery, put forward the management strategies in four areas, as battery SOC estimation, thermal management, insulation detection and charge mode for Li-ion battery pack. Finally, we designed the hardware and software of the Li-ion battery management system, implemented the battery management strategies through the use of software algorithms in the battery management system.During the Peking Olympic Games, a total of 50 electric buses equipped with the BMS have operated and achieved a “zero failure” stable operation.

So, on my century ride the other day, I ate a bunch of food to keep pedaling. I noticed that one of the guys on the ride who rode last time didn't seem to eat much. -- He's a vegan. When I asked him what he was going to eat for this ride he told me he had eaten cherries for breakfast, and he would eat some peanuts and some dried berries that he had in his jersey. WTF
What I'm wondering is how this guy can pedal a fixie 100 miles on solely nuts + berries + cherries + some water. It took me 2 oatmeal packs, 1 egg, on egg burrito from mcdonalds (a rest stop on the way), 4 clif bars, 2 granola bars, ~12 pieces of pizza @ cici's, salad & pasta @ cici's.... and when I got home, I was starving. -- one online calculator estimated about 3,900 calorie burn on top of whatever my basal...

Hey, i'm 25 and i'm giving up on the whole i wanna b a dj thing i was thinking, LOL. I am deciding i wanna grow up and stop partying and have a career. i know it's a bit late but whatever. I am thinking about going back to school and i think i'd like to major in accounting. now i'm not good with math, but i don't mind adding lots of number, using a calculator all day and doing paperwork. so i'm thinking of getting an associates and then seeing if i can get a job as a accounting clerk and then go to school for my bachelors while i continue working. which would be 2 more years for my bachelors right?. now does anyone think that this is a good idea? i know that not everyone who's in accounting do it because they love it. since i'm not that good at math, should i still do it? i know during...
