Tried out a super charger for the first time in MY LR

[wlrd08]

We took a day trip to see the in-laws 88 miles away from where we live. I set the overnight charging to 100% and I had 321 miles for range when we left. Had a couple of short stops before we got on the expressway. The temp outside was around 40 degrees. I pushed the MY a bit and by the time we got there I was at 155 miles left to get back. We had take my daughter direct to practice 84 miles away and were late. The warning message I got from the car was to not exceed 70 to be able to make it. Luckily we arrived with about 6% battery left and a supercharging station a mile away from our destination. The super charging worked like a champ. We got up to 155 mile range in about 14 min. The only weird thing that happened while charging was that we heard a loud ping type nice from the back of the car. It happened twice and no indication of any issues from the car’s charging screen but thought that was weird. I am hoping we did not hear or feel a battery explode or something. Has anyone else noticed this effect while charging at a super charger?

If it sounds like someone throwing a walnut at your car, normal. Metal thermal expansion as it heats up.

Its normal ..there is a lot of power going in and stuff heats up .. you are hearing thermal expansion is all.

That does make a lot of sense given the load and speed of the charger. Great stuff, thanks both for the quick responses!

There is air expansion when packs warm up during super charging in cold climates and when changing elevation. Ithappens to Model 3’s as well. The M3 has a service bulletin dealing with the pack breathers. I’d use that as a reference when talking with the Service Center.

Thanks, good points to ponder for sure!

Thanks, for the link.

You'd think they would've used the new breathers on the Y...

Holy crap you get 321 miles at full charge? Most ive seen is 309

Visited the Supercharger here yesterday just to try the experience and make sure no surprises. I charges for about 15mins and got the clunk sounds as well. Scared my my wife but I explained.

No surprises...just like charging at home but faster and see you see the chargeup cost whereas at home it will be just part of the overall bill.

just wait until there are 4-6+ Teslas all charging in colder weather. You'll hear multiple clunk clunk clunk noises if you crack the window
