Summary:This paper introduces a new approach of black-box modelling of bidirectional battery chargers for Electric Vehicles (EV). Due to the increasing penetration of EV, the number of battery chargers connected to the grid is also increasing, being a challenge to assess the impact of such growing number of battery chargers into the grid performance. The black-box model is able to represent the behavior of the battery charger using the information generated from a number of tests applied to the equipment to be modeled. Due to the variability of the operating conditions a large-signal modelling strategy based on the polytopic structure is proposed. This modelling strategy will be tested with an actual commercial bidirectional battery charger. The experimental tests of the paper illustrate the Grid to Vehicle (G2V) and Vehicle to Grid (V2G) operations.
