We had a similar issue with the HPWC listed as a $750 option in the right column on our
inventory 2015 P85D "
offer" PDF document. We accepted this "
offer" in wiring and put a $5,000 deposit, arranged our financing, and we're ready to complete our purchase until I received our actual Tesla "
purchase agreement" with the
same total price as our accepted "
offer"... but the HPWC line was missing.
When I asked our Tesla salesman, he contact corporate and they acknowledged this "computer glitch" of
inventory "
offer" documents erroneously listing the HWPC "option". He also said our HPWC would be
NOT delivered as part of our
inventory P85D purchase price. I complained vigorously and our awesome Tesla salesman got me an "Open Box" HPWC delivered at no charge so I completed our purchase. However, after our Tesla approved electrician installed our HPWC and I set the charge rate to 80A on our dual charger equipped P85D to test our wiring and the HPWC, the HPWC connector got
REAL hot (155ºF). I contacted Tesla Service who said since my HPWC wasn't on our final
purchase order they wouldn't repair or replace it. Frustrated, I contacted Tesla corporate in writing and they had our service center send out a Tesla Ranger with a brand new HPWC cable which got everything working perfectly. Awesome Tesla customer service IMHO albeit with a lot of time pursuing getting what I'd agreed to when I accepted their
inventory "offer" and they accepted our $5,000 deposit.
So in the end we received an awesome HPWC that was listed in our
inventory "
offer" PDF document.
As for the
HPWC's
80A charge rate, its nice to have in case we ever need a fast charge at our home... but we've honestly only used it once at the 80A rate in the 5 months we've owned our Tesla for a quick "top off" when I'd forgot to plug in the night before. Knowing what I know now I would just install a NEMA 14-50 since it would have been all we needed, the 14-50 would have been cheaper to install, charging at lower amperage is supposedly better for our battery, 100A circuit breaker and wiring... especially since I could always install a HPWC later.
But the HPWC sure looks awesome on our garage wall, especially when its pulsing
GREEN when its charging. Reminds me of Hal9000 from 2001 A Space Oddesy (OK Hal pulsed red)
