METHOD AND DEVICE FOR DETECTING A SHORT-CIRCUIT

摘要

In a charge cable which can be connected to an electric charging device to charge a battery of an electric vehicle, a method for detecting a short-circuit selects a first voltage value for a test voltage. By applying this test voltage to the charge cable, testing is carried out to determine whether there is a short-circuit , a fault signal is output; if there is a no short-circuit, the test voltage is increased incrementally up to a maximum voltage value. The increased test voltage is used to test whether there is a short-circuit in the charge cable or in the contact connected to the charge cable.
