Abstract

The lithium-ion battery is the most expensive part of the electric vehicle (EV). Improving battery performance is one of the most important factors in promoting the EV market by prolonging battery life, reducing the cost of ownership and giving confidence in the product to potential customers. This paper considers a method of improving battery performance that extends the life of the battery and increases holding capacity. This will be realized by finding the best charging profile for an EV battery by identifying, the time that battery can accept charging and the charging profile with minimum effect on battery life.
The analysis presented shows that including rest periods during battery charging reduces battery degradation in two ways. Firstly, it reduces the rate of change in battery internal resistance. Secondly, it slows down the rate of capacity fade. Moreover, it
