The entire charging system, including the car's and the charger, need thermal control. If your car is at a good temperature but the charger just finished a blistering charging session, its components including the cable will be hot and charging performance limited. If the external temperatures are excessively hot, such as many locations in southern Nevada and Arizona, then the charging infrastructure will have challenges maintaining temperatures within operational ranges. Your car can precondition when you tell it to, but the charging infrastructure can't "pre" condition, it dynamically reacts to maintain range. With that in mind, you can try to charge early in the day and/or at a charger that has not been very recently used, but that of course may not always be possible.
