Can someone help me understand what is going on? I have an HPWC with a 100 AMP circuit breaker and a 200 AMP new service to the garage (separate meter). I have used it for about a week and thought it was charging at 80 AMPS. The car says 80 AMPs before I put the charger in. I have been charging to 70%, but today I charged elsewhere to 90% and drove the car home 15 miles, parked it in my garage, and put the charger in. Rated miles is 221. It says 40 AMPS, and can't be dialed up. I took it out, and the car reads 80 AMPS. Is there something wrong with the install? The HPWC? Does it charge more slowly if near the set limit? I don't understand why it wouldn't charge at 80 AMPs.
