I'm not understanding these statements.
Correct me if I'm wrong but paraphrasing this to, "GM could have morphed the EV-1 into the Volt program back in 2000." You still have the battery performance/durability problem with Pb-A and NiMH and you had gas prices in 2002 of $1.20/g. In the mean time you have Li-ion technology starting to become available that might make the vehicle practical now. I'm not saying GM is perfect, but the decisions about the EV-1 and Volt don't seem terrible to me.
1. "problem with Pb-A and NiMH" What problems are there with NiMH batteries during that era? Obviously Pb-A (lead-acid) batteries are bad, even GM recognized that by producing the gen-2 EV1 with NiMH. Why bring up lead-acid? Performance of NiMH is very good. “The GM 1999 EV-1 utilizes a high-performance, longer-lasting GM Ovonic NiMH Generation I battery which stores twice the energy of a lead acid battery for the same weight and volume. It also utilizes a second-generation electric propulsion design that reduces cost and complexity while improving performanceand reliability.” http://www.theautochannel.com/news/p...ess002055.html Here's a Chevron press release. “The advanced Texaco Ovonic Battery Systems NiMH batteries provide more than twice the energy and life cycle of conventional lead acid batteries, are maintenance free and are environmentally benign. NiMH batteries are the enabling technology for electric and hybrid electric vehicles to meet the requirements for next-generation fuel-efficient vehicle applications. Other applications include telecommunications, uninterruptible power systems (UPS) and distributed generation segments of stationary markets.” http://phx.corporate-ir.net/phoenix....0875&highlight= The Toyota RAV4e seemed to run for many years on NiMH battery alone, no ICE to charge them while going down the road. Some RAV4es are claimed to have exceeded a 100,000 miles. Toyota has been using it in the Prius for 10 years.
2. "you had gas prices in 2002 of $1.20/g" So? The Prius was designed and built during that period of low gas prices.
3. “In the mean time you have Li-ion technology starting to become available that might make the vehicle practical now.”
Toyota should have waited to build the Prius until Li-ion came out? Maybe we should wait until the silicon – Lithium batteries arrive? “The new technology, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries.” http://newsservice.stanford.edu/news...re-010908.html
Again, I'm not suggesting the EV1 had to exist in it's 1999 form (all electric) GM could have created a series hybrid using that periods technology. GM, Ford and Chrysler could have all been into hybrids. I'm not just pointing out GM. Look again at the Department of Energy charts for electric cars of that era, notice the range bar graph. http://avt.inel.gov/pdf/fsev/eva/compare_graphs.pdf The EV1 was the most advanced car out there, likely GM could have held the title to the most technologically advanced production car on the road. Toyota did it. “The Prius continues to be the top seller and one of the most technologically advanced and complex passenger vehicles in the market today. It’s also one of the most reliable.” http://articles.latimes.com/2005/jun...ness/fi-prius1
I'm hopeful about the Volt. It's General Motors opportunity to shine. For now all I have is an established past behavior (a conflicted electricity/gas propulsion car company) and words of what they will do.
Thanks to everyone for their constructive comments as we review history. History provides the foundation upon which we build toward the future.
