Abstract:

This paper proposes a hierarchical optimization power control approach to suppress the battery getting

older in plug-in hybrid electric powered vehicles. In the first-level, a variable-threshold dynamic

programming set of rules to distribute the electricity among the power garage device and the engine is

proposed. By including supercapacitor to shape the hybrid power garage device, and the use of adaptive

low-by skip filtering set of rules, the electricity among the battery and the supercapacitor is distributed. To

manipulate the supercapacitor and battery to paintings withinside the ability range, a electricity limits control

module for redistributing the electricity among the engine, the supercapacitor and the battery is considered.

The adaptive low-by skip filtering set of rules and electricity limits control module represent adaptive

electricity allocation technique withinside the second-level. After that, the rain-float counting set of rules is

implemented on this paper to calculate battery getting older price. By the use of the rain-float counting set of

rules, the battery performances are analyzed, and the outcomes display that the adaptive electricity allocation

technique can enhance the battery carrier existence through approximately 54.9% in comparison with the

worldwide dynamic programming set of rules. Considering the preliminary price of the supercapacitor, the

prices of battery getting older, gas consumption, strength consumption, and control price of retired batteries,

in comparison with the worldwide dynamic programming set of rules, the existence cycle economic system

of the automobile is progressed through neathneath the proposed technique.
