My calculations showed that a charge of some 60 hours (after figuring energy I’d use for the trip up to Hyder) would be needed to fully charge the Tesla’s battery before I set off again for Smithers. That placed me at full charge early in the morning of the third day. I didn’t have much wiggle room if I wanted to leave morning of the third day.
Timing how long it took to add one mile of range, I figured we were gaining about 3.3 miles per hour at 12 amps and 110 volts. Unfortunately, on day two a heavy rtainstorm arrived, and with powerlines wet in the Stewart area, the charge sometimes dropped to 9 amps. By unplugging and then replugging, I was able to get 12 amps back again and keep the charging on schedule.
