Abstract

The invention relates to a method for transmitting vehicle information during a charging situation of an electric vehicle (100) at a charging station (300) by means of a charging socket (220), which contains a dongle (230) comprising an evaluation electronics (240), a transmission device (250) and an energy supply device (260), wherein the method comprises at least the method steps of firstly connecting the charging socket (220) of a charging cable (200) to a vehicle-side charging plug (110) of the electric vehicle (100). Then, the cable-side charging plug (210) is connected to the grid-side charging socket (310) of the charging station (300). Signal analysis is then performed by the evaluation electronics (240). Then, if the signal analysis yields that the parameter under examination has a target value or that the target value is absent or completely absent for a certain period of time, a specific signal is generated. Then, if the specific signal appears at the dongle (230) or is completely absent within the specific period of time, the vehicle information is transmitted.

Description

Remote inquiry-capable system for obtaining component state through charging socket Technical Field The invention relates to a method for transmitting vehicle information using a charging plug, an electric vehicle and a charging socket, wherein the charging plug comprises a Dongle (Dongle) and the electric vehicle comprises evaluation electronics. The invention also relates to a charging plug for an electric vehicle, wherein the charging plug comprises a dongle and the dongle comprises means for detecting the presence of a specific signal and means for enabling the transmission of vehicle information of the electric vehicle and/or for enabling a charging process. The invention also relates to an electric vehicle comprising a charging plug with dongle. Background The electric vehicle must be charged periodically. Here, the battery pack is generally a weak point. Especially when the battery packs have undetected defects, the battery packs may be considerably damaged due to heat development, or even fire. Thus, before the battery pack is connected to the power grid, it should be checked whether the battery pack is fully functional or damaged. While the vehicle is traveling, vehicle parameters are continuously monitored by the in-vehicle electronics. The vehicle data may be read by a technician through an onboard computer of the vehicle while the vehicle is stationary. The use of an on-board computer for diagnosis prior to each charging process is costly and carries the risk of forgetting or simply being done at random. In parked (locked) vehicles and during the charging process, in which the vehicle is also usually locked, no vehicle diagnosis is performed, since when the ignition is switched off, the diagnostic system of the vehicle itself is usually likewise switched off and thereby rests. Methods are known from the prior art, such as radio connections, by means of which the vehicle can communicate with external devices, such as external devices of mechatronics personnel. Such a radio network may be implemented, for example, as a Wide area network (Wide AreaNetwork, WAN) or as a global system for mobile communications (Global System for Mobile Communications, GSM).

Connecting a charging plug at the cable side with a charging socket at the power grid side of the charging station; c. performing a signal analysis by the evaluation electronics; d. Generating a specific signal if the signal analysis yields that the parameter under examination has a target value or that the target value is absent or completely absent for a specific period of time; e.
