Technically speaking, the battery swap machinery devised by Better Place is working well.
Jason Wolf, vice president of the electric charging station company, told an audience at the Smart Grid Innovation Symposium that the company has swapped the battery in and out of a prototype electric car in Japan 1,000 times now without any flaws or problems. The battery is swapped by machines and not humans – it weighs about 400 pounds, after all.
Some of the questions surrouding the company, however, have to deal more with the economics than the technical aspects. We won't know the answer to the more practical questions for years, but it's an interesting subject to debate. One audience member asked whether consumers would accept battery swapping. What if the new one doesn't work as the first battery they had?
Not a problem, said Wolf. Better Place owns the batteries and therefore assumes that risk. If you don't like the performance of a battery, you just swap it out.
"You don't care about the mileage on the battery because you dont' own it," he siad. "That [battery mileage and health] is more of a problem for the owner of a Tesla."
Owning the battery, though, will require Better Place, a relatively small company, to shoulder a huge financial burden. Electric car batteries might cost $12,000 to $25,000 each. Thus, if the company has 100,000 customers, it needs to own $1.2 to $2.5 billion worth of batteries. 100,000 cars is not that many. 400,000 new cars get sold in the Bay Area alone each year. If 10 million Better Place vehicles were to hit the road, that would mean owning $120 to $250 billion in batteries. Hmmmm. Might make more financial sense to buy something cheaper and less likely to be stolen and dismantled, like the state of New Hampshire.
How quickly will the conversion to electric cars take place? It's hard to say. In 1900, only around 42 percent of the cars ran on fossil fuels. Most of the rest ran on electricity or steam. The declining price and better performance of petroleum made it the winner in just a few years. By the late 1920s, electric was dead. That's pretty quick, and argues that a significant technological shift could occur before our eyes.
On the other hand, the car industry was new then. It is now an established business that grows much more slowly. Micah Myers at Claremont Creek Ventures researched electric cars at a previous job. He said that the vehicle base only turns over about six percent a year. Even if every new car bought were electric, it would take 20 years to go all electric. "That's not going to happen. It is a 40, 50 year problem," he said.
Then again, policy initiatives could drive sales. Denmark charges a tax at registration of 180 percent of the price of a car, says Lars Beer Nielsen, the technology attache for Innovation Center Denmark. Electric cars are exempt for the next few years. Thus, a $40,000 car costs $112,000. That means a Tesla Roadster costs as much as a low-end Acura.
