The report describes a device for the recharge of a microEV battery implementing partial battery swap developed by RSE. The battery of the rack can be charged both from the grid and from a PV generator, and the rack is able to performe V2H functions. The results of the EMC standard compliance tests carried out before the installation of the rack are described in the report.

The report describes a research activity undertaken as a follow up of the activities performed in the European project “Free-Moby”, which deals in a synergic way with the issues of electro-mobility, smart charge of electric vehicles, and vehicle-to-grid applications of the traction batteries. The project focuses on the development of a micro electric vehicle, equipped with two independent powertrains, each one comprising an electric motor, an inverter and a battery pack able to support, individually, the running of the vehicle. One of the two battery packs is made of manually removable modules in order to be extracted from the vehicle according to a charging procedure, known as partial battery swap.

The battery removed from the vehicle can be charged in an external stationary rack, which includes a PV generator and is able to exchange energy with the electric power grid and to supply a domestic electric load, realizing vehicle-to-home functions. RSE has developed a version of the device different from that defined in the European project, because the first Free-Moby version of the device was not compliant with the Italian standard CEI 0-21 Variante V1; moreover, the new version will be more representative of a wider range of applications. The document describes the developed device and presents the results of some preliminary functional tests and EMC compliance tests executed on the device in accordance to international standards, before the definitive installation at the RSE testing facility.
