We recommend limiting the amount of DC charges, and ending DC charges at 80% state of charge as charging between 80 and 100% can incur high charging costs due to the time to completion. Frequent use of DC charging could result in reducing your battery’s efficiency and lifespan. This is more pronounced on the standard range battery pack versus the extended range battery pack.
In cold temperatures, you may notice that DC charging takes longer when the ambient temperature drops below 50°F (10°C). Shutting off climate control or reducing climate control temperature and fan settings for the first 10 to 15 minutes of DC charging will allow the battery to warm up and improve the charging rate.
Note:   When the temperature is below freezing, fully turning off cabin heat for the first 10 to 15 minutes of DC charging could significantly improve the charging rate.
