چکیده
Abstract In order to improve the economy of hybrid electric-electric ship, parallel electric ship is taken as research object, and an energy control strategy based on minimum equivalent fuel consumption proposed. The efficiency factor its correction function are used maintain balance battery power, target optimization adjusted power rate battery, thereby realizing for traveling ship. Finally, Matlab/Simulink simulation. experimental results show that when with used, 1.95L less than CD-CS-based strategy, saving 31.2%. At same time, engine motor work Efficiency greatly improved.

Modification of Equivalent Consumption Minimization Strategy for a Hybrid Electric Vehicle
Equivalent consumption minimization strategy (ECMS) is one of the main real-time control strategies for hybrid electric vehicles (HEVs). This paper proposes a method to modify this strategy. This modification reduces calculation time of ECMS and therefore, facilitates its application as the real-time controller. Dynamic programming (DP) method is employed to reach this aim. This method is appli...
متن کاملAdaptive Equivalent Consumption Minimization Strategy for Hybrid Electric Vehicles
This paper proposes a new method for solving the energy management problem for hybrid electric vehicles (HEVs) based on the equivalent consumption minimization strategy (ECMS). After discussing the main features of ECMS, an adaptation law of the equivalence factor used by ECMS is presented, which, using feedback of state of charge, ensures optimality of the strategy proposed. The performance of...
متن کاملA Supervisory Control Algorithm of Hybrid Electric Vehicle Based on Adaptive Equivalent Consumption Minimization Strategy with Fuzzy PI
Abstract: This paper presents a new energy management system based on equivalent consumption minimization strategy (ECMS) for hybrid electric vehicles. The aim is to enhance fuel economy and impose state of charge (SoC) charge-sustainability. First, the relationship between the equivalent factor (EF) of ECMS and the co-state of pontryagin’s minimum principle (PMP) is derived. Second, a new meth...
متن کاملResearch on Control Strategy of Series Hybrid Electric Vehicles
The paper presents the analysis of two basic control strategies, the series thermostat control strategy and the series power follower control strategy, used for series hybrid electric vehicles. One of these control strategies, the series thermostat control strategy, is programmed and installed in an electronic control unit to manage the power flow of a two-seat series hybrid electric vehicle de...
متن کاملEquivalent fuel consumption optimal control of a series hybrid electric vehicle
Improvements in hybrid electric vehicle fuel economy with reduced emissions strongly depend on their supervisory control strategy. In order to develop an efficient real-time supervisory control strategy for a series hybrid electric bus, the proposed equivalent fuel consumption optimal control strategy is compared with two popular strategies, thermostat and power follower, using backward simulat...
