| description | PROBLEM TO BE SOLVED: To provide a high-voltage battery system of a vehicle which detects the presence/absence of fusion of all individual relays in the high-voltage battery system, with ensured protection and safety for the battery system.SOLUTION: A relay fusion detection method for a high-voltage battery system of a vehicle includes: a first process S100 having a step S101 for connecting a negative electrode relay coupled to a negative electrode of a high-voltage battery, a step S102 for connecting a pre-relay coupled in parallel to a positive electrode relay coupled to a positive electrode, and a step S103 for inspecting fusion between the pre-relay and the positive electrode relay by measuring the magnitude of current upon the pre-relay connection; and a second process S200 having a step S201 for connecting the pre-relay, a step S202 for connecting the negative electrode relay, and a step S203 for inspecting the presence/absence of fusion of the negative electrode relay by measuring the magnitude of a load current upon the negative electrode relay connection. The first process S100 and the second process S200 are alternately carried out each time the fusion of the relay is inspected. |
