Abstract

AbstractThis paper presents a validation based on simulation result of an electric vehicle (EV) battery charger for power transfer between two EVs (vehicle-to-vehicle (V2V) operation) using only one converter per EV. The traditional topology needs a connection between the EVs and the power grid, consisting in a combination of two operation modes (V2G and G2V). In addition, the power transfer is made using a total of four power converters, two dc-dc and two dc-ac power converters, which represents more energy losses. In contrast, the presented topology discards a connection with a power grid and the charging operation can be done anywhere through the connection between two EVs. Furthermore, the proposed topology only needs two dc-dc power converters, one per EV, allowing the power transfer between EVs becoming more efficient and useful.KeywordsElectric Vehicles (EVs)Battery chargingVehicle-to-Vehicle (V2V)Power transfer
