Simple daily routines can help maintain that performance for an even longer period of time. There are instances of electric taxis and delivery trucks achieving even greater mileage with their original batteries still in use, and some automakers are already seeing batteries last well over 150,000 miles with little loss of range. Technological developments in batteries keep enhancing their performance and longevity. To withstand wear and sustain capacity over time, new chemistries and improved battery management systems are being developed.
