US 2025/0326319 A1 · CHARGING ADAPTER FOR ELECTRICALLY CONNECTING A MOTOR VEHICLE TO A CHARGING DEVICE

Abstract

A charging adapter for electrically connecting a motor vehicle to a charging device, includes a temperature sensor and a modulator. The charging adapter is configured to be electrically connected to a first connection element and to a second connection element simultaneously. The first and second connection elements are not electrically connectable to each other. The charging adapter is configured to simultaneously transmit a transmission signal via a first cable element and a charging current via a second cable element from the charging device to the motor vehicle. The temperature sensor is configured to determine a temperature of the charging adapter and transmit the temperature to the modulator. The modulator is configured to modulate a modulation signal to a transmission signal. The modulation signal includes an indication of the temperature.
