As a result, EVs can travel long distances on a single charge because they have high energy storage capabilities. The charging time for Li − ion batteries is also relatively fast when compared with other types of batteries. Li − ion batteries'' price may decrease by 52 % by 2030, despite battery prices rising due to a variety of factors.
The deployment of fast charging compensates for the lack of access to home chargers in densely populated cities and supports China''s goals for rapid EV deployment. China accounts for total of 760 000 fast chargers, but more than 70% of the total public fast charging pile stock is situated in just ten provinces.
