<p>The invention concerns a device for pre-loading an electric power system of a vehicle with electric drive. The electric system comprises a storage battery (3), a main contactor (7), a monitoring system (15), and power elements constituting a capacitive loading (5, 6) of the system. The system capacitive loading is capable of being supplied by the storage battery (3) via two supply lines (1, 2), the main contactor (7) being provided to disconnect said two lines (1, 2). The pre-loading device comprises a pre-loading relay (11) arranged on two pre-loading lines (9, 10) parallel to the main contactor (7), the pre-loading relay (11) being provided for disconnecting said two pre-loading lines (9, 10). The pre-loading device comprises a thermistor (12) arranged on one of the pre-loading lines such that the energy release caused by a short circuit or an insulating fault is completely dissipated in the thermistor (12).</p> |
