Tesla CEO Elon Musk hits out at the Nissan Leaf's battery pack

The Nissan Leaf’s battery technology has been called "primitive" by Elon Musk, CEO of electric car company Tesla.

In response to Nissan’s recent cost-per-kilowatt hour claims that it had broken the $400 (£250) barrier, Musk said, in a conference call with shareholders, he didn't believe Nissan has overtaken Tesla in reducing battery costs and claimed the Japanese firm was using a "much more primitive level of technology" than Tesla.

Musk said that the Leaf’s battery pack was not even as good as the first prototype his company produced because of its less-sophisticated cooling system. He added that the Leaf technology would struggle in extreme temperature conditions, suffering “huge degradation” when cold and not functioning properly when hot.

Tesla uses active liquid thermal control (which will also be used in the Chevrolet Volt), while the Leaf pack uses an air cooling system; Musk claims this battery technology would mean the Leaf's battery pack will have temperatures “all over the place".

Nissan supports its battery pack with an eight-year, 100,000-mile warranty. Musk said the battery cost in Tesla's upcoming electric Model S saloon would be around 40 per cent less than its only current model, the Roadster.

As mentioned earlier, the UK is heading for a big electricity shortfall even if we take EVs out of the equation because of the complete lack of investment in any sort of power station - coal or nuclear - over the last 15 years. And if Norway can't produce effectively free hydroelectric power with its topography, once the infrastructure costs have been amortised of course, then surely nobody can.

I don't live in UK but occasionally I visit your sites,and I don't really understand the great fuss that is creating about EV vehicles in UK. As I know your main source of energy is from coal and nuclear plants( am I wrong?),and soon as you go with these EVs you'll need much more production from these plants (and import!), more pollutions and higher cost for electricity.Maybe the reason is less sunny days?Now, don,t get me wrong, I have great respect for experts in your country, and I'm sure they know the reasons,it, simply I don't understand! Hydrogen fuel cells are much better option, more expensive in the beginning maybe, but cleaner and in a longer run it pays off!

what the Norwegian Government thinks about EVs if they are prepared to pass them over in favour of hydrogen when they have so much free electricity (a big chunk of which they sell to the UK).
But, there is no such thing like "free electricity"! The catch with these refiling hydrogen stations is that they are powered from solar panels and wind source, so they can really be called clean energy source. They produce hydrogen from water through hydrolysis and at the end when water is produced during driving, the cycle is closed. Smart guys, so they can export their energy abroad for good money!
