With the rapid increasing of motor stock in China, the pressure from climate changing and energy safety is more pressing and the GHG emission and fuel efficiency regulation are more rigid to initiate the electrification of the transportation. Despite the rapid progress currently being made in the global electric vehicle technologies, substantial barriers to widespread vehicle adoption still exist, such as higher price, inconvenience charging, limited range, battery environmental issues etc. In this paper, an innovative business model of battery leasing is provided and its commercial potential is analyzed as well. The new business model will pave the way for the EV rolling out in China.
