ABSTRACT: Single energy electric vehicle was set as the study object. Feedback current range was determined by analyzing electric vehicle regenerative braking principle. The mathematical models of battery maximum charging current was established based on hybrid pulse power characterization method. Considering the reasonable distribution of regenerative braking and hydraulic braking, with the braking current as the control object, electric-hydraulic regenerative braking strategy based on variable current feedback was proposed, and simulation of the control model was carried out. The result show that this regenerative braking strategy improves the recovery efficiency of braking energy under the premise of ensuring battery charging safety.

Keywords : Electric vehicle; Regenerative braking; Variable current feedback; Control strategy.
