Model predictive current control of a slow battery charger for electric mobility applications

摘要

This paper presents a model predictive current control applied to aslow electric vehicle (EV) battery charger. Taking into account the similaritiesbetween the power converters inside the EV, it is possible to combine the batterycharger and the motor driver in a single integrated converter, thus reducing theweight and volume of the proposed solution, and also contributing to reduce thefinal price of the EV. Due to the bidirectional power flow capability of the integratedpower converter, when working as a slow EV battery charger it can operatein grid-to-vehicle (G2V) mode and in vehicle-to-grid (V2G) mode, contributingto make EVs an important assets in the future smart grids. The integratedpower converter working as battery charger operates with sinusoidal current andunitary power factor, contributing to improve the power quality of the electricalgrid. This paper provides simulation and experimental results that validate themodel predictive control algorithm applied to the proposed integrated power converterworking as slow EV battery charger.
