AI Technical Summary
Technical Problem
Existing electric and hybrid motor vehicle charging systems are prone to mechanical blockages due to ice, snow, mud, and debris accumulation at the underbody charging ports, particularly in harsh winter conditions, leading to reduced system availability.
Method used
A cleaning device utilizing the Venturi effect to generate airflow or fluid flow over the charging port hatches during vehicle movement, preventing blockages by using pressurized or depressurized air and optionally supplemented with sprayed fluids, without additional energy consumption.
Benefits of technology
Efficient cleaning of charging port hatches is achieved during vehicle operation, maintaining system availability and preventing mechanical blockages, while being cost-effective and compact.

Abstract
The invention relates to an electric motor vehicle (1000), the underbody (200) of which comprises a charging tray (300) closed by a hatch (400) facing the ground, and comprising a cleaning device (500) that cleans the underbody charging tray (300) by aerodynamic effect when the vehicle (1000) is in motion. This cleaning device (500) comprises at least one Venturi nozzle (600) arranged in a longitudinal direction (X) in the vicinity of the charging tray (300) and configured to subject its hatch (400) to a flow of pressurized or depressurized fluid for cleaning this hatch (400).
