I intentionally choose 150 kW chargers over the 350s if I have the choice. Here's why based on a large number of EA stations used on multiple trips (of course, this is just one person's observations):
- The 150s are more reliable. I've had many 350s derate after a minute or two to 96 kW. Unplugging and reconnecting 2 or 3 times gave the same error. This even occured at the EA where the 350s were brand new and activated only 2 weeks prior. Outside temps were moderate, but I still think this is thermal related.
- Like Out of Spec found out in testing, I also find that there is little to no difference in charging time. Yes, a 350 kW pedestal will put ot 220 kW, but only for a very short time, and then drop to a rate lower than the 150s for the same state of charge. The area under the curve from 10-70% SOC is almost identical. The 150s rise to 160 kW but drop off at a slower rate.
The 350 kW pedestals have been a source of frustration for me. I'm squarely on Team 150.
