It seems that Tesla vehicles are becoming the benchmark for all full electric vehicles to live up to. Elon Musk, the boss of Tesla has a vision, and he really is making it a reality.
Not content with just using existing tech, Musk and Co are pushing development in all areas, and the latest area to benefit is the battery, both in terms of power and range.
Instead of the 90 kWh battery that quite literally powered them to success, they took the battery pack and re-engineered it.
Photos from a salvaged Tesla have been posted on the internet, the photos show a battery pack that has been dismantled, it shows that Tesla have managed to increase the number of 18650 Lithium-Ion cells inside the pack, along with a replaceable connector that should allow the new battery to be retro-fitted into the older Tesla model.
The 10 kWh increase means a 0 – 60 MPH time of 2.5 seconds(!!!) and an increase in range by approximately a further 20%.
Elon Musk goes on to explain: “The cell is the same, but the module and pack architecture has changed significantly in order to achieve adequate cooling of the cells in a more energy dense pack, and to make sure that we don’t have a cell to cell combustion propagation”. In other words, they’ve upgraded the cooling to stop the cells becoming a bomb.
Just for reference, for those of us that aren’t electrical engineers, that sort of power (100 kWh) is over 11 times the amount that the average home uses on an average day.
JB Straubel, Tesla’s Chief Technical Officer (CTO) says that it’s a big change in battery technology; a complete redo on the battery architecture.
For us, the next question is what else do Tesla have up their sleeve?
Tesla’s best seller is second in the charts (behind the Nissan Leaf), but that is purely pricing options, as far as the nation is concerned (and possibly the world), Tesla are the leading electric vehicle manufacturer.
They’ve proven that technology never stands still, and rather than playing catch up with each next development, Tesla are bringing those developments to market themselves. This should mean that they’re always on top of the EV game; sure in another 10 years or so, when some of the other world brands embrace EV technology whole-heartedly, Tesla are going to have a fight on their hands, but they’ll have decades of experience, knowledge and know-how behind them.
