Most studies on the acceleration process of electric vehicle focus on reducing energy consumption, but do not consider the impact of the power battery discharge current and its change rate on the battery lif. The existing research on the electric vehicle (EV) energy consumption mainly focuses on the. The model of EV energy consumption during accelerating processAccording to the principle of longitudinal dynamics of automobile32, when the EV accelerates on g. On the basis of research in reference35, for a given acceleration condition which the initial velocity and the final velocity and the total acceleration time are constant, when the EV accelerat. When the EV accelerates with different acceleration curves, its energy consumption and battery life are different. In this paper, the interaction mechanism between the EV. (F_{{text{t}}} (t)) : Traction force (N)(uleft( t right)) : EV velocity (km/h)(eta_{T}) : .
