Simulation of an EV-HEV Charging Station for Multichemistry Batteries Using Energetic Macroscopic Representation (REM)

Massification of electric vehicles (EV) and hybrid electric vehicles (HEV) requires the implementation and optimization of battery charging stations adapted to charge multi-chemistry batteries. Charging algorithms must identify the battery technology (Li-Ion and NiMH) and perform a charge which minimize the charging time while maximize the batteries lifetime. In this paper, Energetic Macroscopic Representation formalism is used to model a charging station with integration of photovoltaic generators. Simulation results illustrate the recharge of a Nissan Leaf and a Renault Twizy Li-Ion - EV and a Toyota Prius NiMH HEV charging.
