The invention discloses an electric vehicle charging connection wake-up detection device, comprising: an isolation circuit, a logic control circuit, and a gun insertion signal output circuit; The terminal is electrically connected with the control terminal of the gun signal output circuit, and controls the output signal of the signal output port of the gun signal output circuit; the charging gun input terminal of the logic control circuit is connected with the charger plug confirmation signal end of the electric vehicle, and the logic control circuit According to the plugging signal of the charging gun input end, the output end of the control isolation circuit is connected or disconnected with the input end of the isolation circuit. The invention provides long-term power supply through the battery of the whole vehicle, and avoids long-term discharge of the small battery by setting an isolation circuit, and realizes effective isolation of the output circuit of the insertion gun signal through the isolation circuit when the gun is not inserted, thereby realizing ultra-low quiescent current .
Description
technical field [0001] The invention relates to the technical field related to electric vehicles, in particular to a charging connection wake-up detection device for electric vehicles. Background technique [0002] In order to prevent the mechanical damage of the charging pile caused by the user moving the car with the gun inserted, it is currently necessary to start the vehicle and wake up the on-board charger. After the charger detects the status of the gun inserted, it transmits the status of the gun inserted to the vehicle for judgment through communication. . [0003] However, when the car is actually in use, such as starting and driving, the on-board charger does not need to be woken up. Contents of the invention [0004] Based on this, it is necessary to provide a charging connection wake-up detection device for electric vehicles in view of the technical problem that the detection of the plug-in state of the charging gun needs to start the vehicle unnecessarily and...
