As we sit here on the verge of an autmotive revolution, a significant amount of uncertainty remains.
Early adopters want electric cars here and now, and are willing to pay more to get them, but how large the market will eventually be, and how fast it will grow is unknown.
It is this uncertainty and lack of concensus that keeps automakers guessgin. It is a large part of why GM cannot project what ultimate Volt sales volumes will be or how many different EREV models they should build.
A new study follows others in painting a more pessimistic picture.
The Boston Consulting Group released a report earlier thus week which concludes without a battery breakthrough, lithium ion battery costs will limit widespread adoption of electric cars through the next decade.
The study claims that automakers are basing their sales projections on being able to acheive a cost of $250per kwh for lithium ion cells. They argue that although those prices have been achieved in the consumer electronics segment, the complexity of car batteries makes it untenable.
They report current electric car battery cost as being from $1000 – $1200 per kwh, and that in addition to complexity, longevity requirements and the needed technology and redundancy to obtain them will stricly limit ability to reduce cost.
“Given current technology options, we see substantial challenges to achieving this goal by 2020,” said Xavier Mosquet, Detroit-based leader of BCG’s global automotive practice and a coauthor of the study. “For years, people have been saying that one of the keys to reducing our dependency on fossil fuels is the electrification of the vehicle fleet. The reality is, electric-car batteries are both too expensive and too technologically limited for this to happen in the foreseeable future.”
BCG still expects about 26% of global auto sales to be electrics and hybrids by 2020, or 14 million cars. Of this group, they project, 1.5 million will be fully electric, 1.5 million will be range extenders, and 11 million will be a mix of hybrids. Seventy percent will use lithium-ion technology.
They warn, however, that by 2020 a 15kwh pack in an EREV would still effectively cost consumers $8000 to $10000 per vehicle, making those cars more expensive than their ICE counterparts, thereby limiting demand.
It is expected that the early EV market will be driven by early adopters and tax credits but by 2020, the total cost of ownership versus ICE cars will determine the market size. If there is a low cost battery breakthough, or if gas prices rise substantially the market could improve.
