Tesla’s Big Bad Battery Secret, 95KwH And More

Ain’t she perdy?  And with a whooping 95KwH pack, she might be the clincher for many electric vehicle, EV skittish would-be owners.

The gist is that we know, EV would-be owners have the over-hyped “range anxiety”.  While we could spent posts after posts pointing the finger at over-active marketing departments from threatened car makers, the truth of the matter is that even 100 miles is more than sufficient for anyone.  How about 300 and more?

The Model S.  The Model S speaks for itself.  Ever since its introduction, articles have been pouring in, mostly praising it.  The first EVs will come with two options, 165 or 230 mile range battery pack.  While this is feasible with today’s technology, 300 miles does raise some eyebrows.

Technically Speaking.  In order to get a four door electric sedan to travel 300 miles or more, the lithium battery pack would virtually out-weigh any gains.  Simply put, it would be too heavy to feasibly get the car that far.  So how come Tesla Motors says there will be a 300 mile version later?  Simply put, because Tesla Motors is working on its very own lithium and has broken a barrier.  Tesla feels it can squeeze more energy from its lithium batteries design.  They would also weigh less.

At this stage, everything so far is unconfirmed and straight form the rumor mill but we will vouch on this one.  The Model S is looking better all the time.
