Problems solved by technology

However, such a coolant circuit can be damaged below the permissible minimum bending radius of the charging cable, which can lead to leakage of the cooling medium
In addition, in particular in the area of ​​the plug connector of the charging cable, falling below the permissible minimum bending radius can also lead to an impairment of the contact protection of the plug connector of the charging cable

Abstract

A method for monitoring a liquid-cooled charging cable of a charging station for a traction battery of an electrically operated motor vehicle. Undershooting of a minimum permissible bending radius of the charging cable is detected, and the undershooting of the minimum permissible bending radius is indicated to a user or charge point operator or service employee.

Description

technical field [0001] The invention relates to a method for monitoring a liquid-cooled charging cable of a charging station for a traction battery of an electrically driven motor vehicle, to such a liquid-cooled charging cable, and to a system comprising such a charging cable for Charging station for traction batteries of electrically driven motor vehicles. Background technique [0002] Charging cables are known from the prior art by means of which an electrical connection can be established between a charging station and a traction battery of a motor vehicle for charging the traction battery. [0003] The charging cable can either be uncooled or have a cooling device, in particular an active cooling device. Uncooled charging cables generally have a very high effective weight and low flexibility due to normative requirements. The active cooling device can be designed as a liquid cooling device. The charging cable can be liquid cooled in this way. Such a liquid-cooled ch...
