Disassembling The Tesla Model S Battery Pack

Packing up to 85 kWh of power, the Tesla Model is by far the most powerful electric car you can buy today, storing enough power to take the big sedan up to 265 miles per charge. That’s enough energy to power the average American home for almost three days, which is just what one Tesla owner plans to do.

Before that though, wk057 decided to tear into a spare 85 kWh battery pack he bought from a salvaged Model S. He posted the pictures over at the Tesla Motors Club forums, peeling back the skin of the battery pack and giving eager fans a look at the nitty gritty details that power their favorite electric car.

You’ll have to check out the forum post to check out the pictures, and this is definitely one of those “Do NOT try at home” sorts of things, unless you’re of the electrical engineer persuasion. There’s enough power in the pack to zap you to death several times over, and one wrong move can brick the battery, making it an expensive, useless lump.

I’m not engineering type, but I do know that Tesla’s battery pack arrangement is a closery-guarded secret, and few people have ever pried back the protective covering on this expensive battery. Those of you who know what you’re looking at can probably provide more details than I can, though the one thing I gathered is that any spot marked with orange is a definite DO NOT TOUCH. You’re welcome.

So what’s the game here? wk057 wants to set up an off-grid solar panel setup, using the Tesla battery to store daylight so at night (or on overcast days) he has plenty of power to draw from. Coincidentally, this seems to be the same business plan Elon Musk is aiming for with Tesla and Solar City. Big enough battery packs could store locally-sourced solar or wind power during peak output and dole it out during the night. The average home uses about 30 kWh of power per day, a little more than a third of what the Model S can store.

This plan doesn’t rely on green power either; Tesla owners could load up on cheap overnight power when utility rates are lower, and use it during the day. That puts less strain on power plants, and saves a lot of cash over the long term. Looks like this guy could be on the cutting edge of the green energy revolution.
