In a study published by the Idaho National Laboratory (INL) it was shown that the charging time for an electric vehicle (EV) grew significantly as the ambient temperature lowered. The study reviewed data gathered from a fleet of EVs in New York City and showed that as the temperature continued to drop the charging time multiplied by as much as three times that of vehicles in warmer temperatures. Per the article, these charging times can be attributed to the onboard battery management systems limiting¬†“the charging rate to avoid damage to the battery.” This study can be important for manufacturers to better understand how their vehicles and battery management systems may react for customers living in colder climates and can be used as a basis to perform additional research.
