Abstract

The invention discloses a relay detection device and method, a relay, a high-voltage distribution box and an electric vehicle. One end surface, adjacent to an armature, of an iron core of a relay is provided with a microswitch and the microswitch is arranged between the iron core and the armature; a switch key of the microswitch is aligned with the armature or the iron core; upon energization of the relay, the armature can be attracted to get close to one end surface to extrude the switch key to close the microswitch; when the relay is powered off, the armature is far away from one end surfaceof the iron core to reset the switch key, so that the action state of the microswitch is judged according to the difference of overcurrent when the microswitch is switched on and switched off, and the pull-in state and the switch-off state of the relay are determined according to the switching-on state and the switching-off state of the microswitch. The purpose of detecting the relay is achieved,the state of the relay can be accurately detected, and reliable operation of the electric vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a relay detection device, a method, a relay, a high-voltage distribution box and an electric vehicle. Background technique [0002] With the continuous deterioration of the natural environment, environmental protection products have been launched in various fields. For new energy vehicles, the power system is a necessary condition to ensure the safe and stable operation of new energy vehicles. As a switching device in the power system, the relay is responsible for the power battery driving the motor. The power connection switch of the car plays an important role in the safety of the power supply of the car. [0003] When the car needs to be charged, the car is charged through the high-voltage power distribution box. During high-voltage power distribution, the car is connected to the high-voltage circuit by controlling the conduction of the relay in the high-voltage power distribution box....
