On Friday I stopped at a supercharger, plugged in, and mosey’d to the nearby Starbucks with my laptop. This supercharger location posted 30 minutes max and the time for my charge was @ 20 minutes. Got my Starbucks, signed in on my laptop, and about 15 minutes later headed back to my car. I arrived with car charged to my set limit. That evening I got an email “Supercharger Idle Fee”. Here’s what the email said:
“Idle fees (up to $1.00 per minute) are applied to cars occupying a Supercharger after completing a charging session. Idle fees only apply when at least half the station is in use.” “7 min. idle at $0.50/min.”.
I didn’t know about Idle Fees (I think this is a GOOD thing to keep people from blocking a needed charger location) and thought I’d get back to my car in time (I was 7 minutes late). But the Tesla app only hollers when the charge is complete and does not give an early warning. The estimated charge completion time shown when first plugged in varies, so the initial completion time is not reliable.
Charge times vary during the charge process (heat/state of charge/multiple vehicles using charger/ etc.)., and owners hang out at locations with varying distance from the car, so it’s hard to guess how much time is needed to get back to the car on time (i.e., arrive when charging is complete). So I called Tesla support and recommended:
Ø The mobile app should allow giving an alert prior to charge completion, giving the owner time to get to his car before getting ding’d.
Ø Perhaps this early alert feature might consider how far you are from your car (i.e., phone to car distance), and calculate the time it might take to get back to your car, and thus calculate how much early warning to provide … or just let the owner specify how much lead time is needed to get back to the car. When the car’s variable charge rate calculates “EstimatedCompletionTime – WalkToCarTime”), that’s when to send the alert to the owner.
This would help folks to get back to their car close to when their charge time is complete without having to guess.
