Electric vehicle performance and design index

There are a number of design criteria for electric vehicles (EV), the simple ones are the battery related such as state of charge and state of health. However, for a successful electric vehicle design and performance test, there are many other criteria in need to be examined. This paper proposes a number of design parameters for this new direction of EV assessment. Each index or performance ratio will significantly affect the vehicle design and the vehicle performance. The paper gives a new concept of an EV design based on a number of new performance indexes and design indexes.
