Would you like to see a race car running on lipos: http://www.proev.com/ (It uses 565lbs of lipos). They could've gotten better performance even with the now older A123 2.3Ah cells that we use in our R/Cs. The LiFePo4 chemistry does show it's safer, but it also has its trade off. My point is, for a car such as the Tesla, they need to use better cells and not just some laptop energy cells. Now how do you feel having 1000lbs. of non high discharge rate cells behind you? That's what you get with the Tesla at $120k. |
your right. for 120k you should be getting some sick battery of the future or at least something that is high quality. Im not saying that lipos are unsafe its just that they have more of a chance to explode, burst, catch fire, or something along those lines than lets say a nimh batt. Sure most of the problems are user errors, but those small amounts of manufacturer defects would grow once you throw hundreds of lbs of the stuff in the trunk of a car. There has got to be a number of tests that the tesla manufacturers will go through to prevent this stuff so it wont happen, and it is unfortunate that they are not using the higher grade batteries, but maybe when you get the car you can mod it to use half the weight and produce double the power.
im excited to see this
