Abstract

Under the initiative of sustainable development, electric vehicles enter the automobile market and gradually gain popularity. However, the vehicle battery—the power source of these new-born cars—is found to have deficiency in its working duration, which limits the usage of electric vehicles to a large extent. Drivers may be trapped on overpasses due to sudden power insufficiency. Moreover, it takes owners a great amount of time, money, and energy to repair or replace their electric vehicle batteries frequently. To solve this trouble, former researchers have suggested numerous potential strategies. This paper mainly focuses on analysing the feasibility of four common solutions about expanding the lifetime of electric vehicle batteries—intermittent charging, temperature control, power maintenance of idle batteries, and driving speed control. By explaining the principles behind each method and considering from various perspectives, such as technological implementation, economic affordability, and security, the author lists the respective advantages and disadvantages of each approach and tries to find the most practical one. Finally, temperature control is determined to be the most feasible based on comprehensive inspection. Admittedly, these four methods all require further improvement to become more effective, but they still hold great significance because of their exploration on extending battery longevity and their supporting role for future study.
