Abstract
The present invention provides a diagnosis system for vehicular DC charging relay, the system comprises a controller, two resistor clusters R1 and R2, and a switch S, wherein, two resistor clusters R1 and R2 are bridging in a serially connected way in between the DC charging high voltage cables of the vehicle, the resistor cluster R1 consists of two serially connected sub-resistors, and the controller is able to measure a voltage V1 at a common terminal of the two serially connected sub-resistors via a first voltage detection port, the resistor cluster R2 consists of two serially connected sub-resistors, and the controller is able to measure a voltage V2 at a common terminal of the two serially connected sub-resistors via a second voltage detection port, the controller is able to execute a diagnosis operation, and the diagnosis operation is based on the measurements of the voltages V1 and V2.
