Study on the Closed-Loop Control Strategy of Voltage for Pure Electric Vehicle in Limp Mode

Abstract:

In order to avoid the nonreversible damage to the batteries because of over discharge when the pure electric vehicle is moving, this article proposes a driving control strategy in limp mode due to under voltage. Firstly, research the discharge characteristics of the lithium battery pack. Secondly research and develop the control strategy that limit the motor torque by the closed-loop control of voltage. Finally develop the strategy model using MATLAB/Simulink, and finish the verification test and prove the control strategy effectiveness by offline simulation.
