Electric vehicle owners are only now starting to become aware of the fact that various battery options may be baked in to their cars at the factory. Big improvements in range and/or performance could come with number codes like “P85”. So, as some of these early EVs approach collectible status, how do you find out, precisely, what battery you’ve got in yours?
This is a problem that guys who buy collectible cars like Chevelle SS 396s or Mustang Mach 1s know all about. They know how to figure out exactly what engine is nestled under the hood of the prize they have their eye on. They will crawl around the engine compartment looking for VIN numbers and engine numbers. They know all the codes the factories used to identify displacement, carburetor, and transmission options. Then, when they find the magic combination of numbers they are looking for, they shout “Oh, yeah, baby! 396 solid lifter, 4 barrel, 4 speed. Sweet!!”
If you own a Tesla Model S, though, that knowledge is all new. Fret not, however, because the folks at Teslarati have the answer.
At Teslarati, they advise that you to look under the car, behind the right front wheel, for a white sticker placed on the side of the battery pack. There are three versions of the battery pack (so far), denominated A, B, and D. Now, while Tesla has not officially confirmed any of this, the speculation is that those letters correspond to the year of manufacture, with D being the latest.
The greatest difference is between the A and B versions. In theory, improved cooling allows for faster Supercharging of the B version batteries. The A version is limited to recharging at 90 kW. The B batteries can be recharged at 120 kW. Owners believe the D version is capable of recharge rates as high as 150 kW. Tesla is steadily increasing the charging rate of its Superchargers. The latest facility – number 100, by the way – is in New Jersey and goes as high as 135 kW.
In addition, there are two performance levels available in the Model S, 60 kWh (identified by the numbers 1020422 on the sticker), and 85 kWh (identified by the numbers 1014114).
Teslarati suggests that owners take a photo of the sticker on their car to verify the battery pack that came with the car. If the pack ever needs replacement, that’s a good way to be sure you are get back a battery that matches the original (if that’s your priority) or nets you an upgrade, which could also be valuable information down the road.
Perhaps, years from now, avid collectors of early Model S cars will crawl under a car, locate the battery sticker and shout, “Oh, yeah, baby! 1020422 D – matched the VIN! Sweet!!”
