Itās better for the battery also!I can attest to the fact that leaving with a preconditioned battery, in 20 degree weather, results in a battery around 40 degrees several hours later. Charging is slower at 40 degrees than at the preconditioned temperature, which has been noted as 59. While charging, the battery rose from 40s to around 95. It then dropped back to 40 as I drove.
I did not compare the time to get to a higher sustained charging speed, but we know it's an issue. Preconditioning would save time with DC charging, noticeable time. The stopgap is to turn off your heat for the first 10 to 15 minutes of DC charging as Ford recommends, to let the heater warm the battery and get faster charging.
