The research on driving cycle tracking was conducted by the National Renewable Energy Laboratory (NREL). The purpose of the research was to understand how electric vehicles are used and to track their charging patterns. According to the research, electric vehicles are driven an average of 29 miles per day. The majority of trips are less than 10 miles, and only a small percentage of trips are more than 50 miles. The data also showed that most electric vehicle owners charge their vehicles at home, during the evening or overnight. This allowed them to take advantage of lower electricity rates and avoid range anxiety.
