PROBLEM TO BE SOLVED: To provide a high-voltage battery system which prevents relay welding by controlling chattering and noise of a relay control signal, which are main causes of relay welding in a high-voltage battery pack using a low-pass filter and a Schmitt trigger.SOLUTION: A high-voltage battery system includes a battery pack 100, a relay part 300, a relay control part 200 and a low-pass filter part 400, wherein the low-pass filter part 400 receives input of a relay control signal output from an output terminal of the relay control part 200 and removes noise to eliminate the primary causes of relay welding. |
