I was at the Santa Monica mall EVSE today and they now have a 3 hour time limit, which would have been fine, except my charge time seems to have doubled. My Entune app showed that I have a current range of 75 miles and four bars until full on extended charge with a time remaining of 3 hours 32 minutes. I used to charge at around 20 miles an hour in Santa Monica and now its down to around 10. I understand that Blink reduced their EVSE output current to 3.3kW, but I didn't think that Chargepoint did. My Chargepoint app showed that I was charging at 5.868kW, but if I really was, I should have charged at near 20 miles an hour. Has anyone noticed extended charge times? Could it be the cold weather?
Are you basing all this on the "data" from the GOM ? If so, it's a flawed way to do it. I suggest counting the 16 "fuel bars" and calculating the range. Sadly, that won't help you between 80% and a 100% charge since the folks at Toyota decided you didn't need to know.
45.0kWh total - 100% SOC
41.8kWh usable- 95.1% SOC = [( 41.8 + 1.0) / 45]
35.0kWh usable- 80.0% SOC = [( 35.0 + 1.0) / 45]
1.0kWh unusable- 2.2% SOC = [1.0) / 45]
Miles Gained per Hour Charging @ 87.5% charger efficiency
70F Ambient temperature - hotter or colder will decrease miles gained

Draft 3:
Here's what 50% looks like, with 10 of 16 fuel bar segments illuminated. Disregard what the GOM says:
