"textContent": "In a normal state, the system startup is performed by turning on the positive-side relay of the system main relay and the precharge relay to charge the high-voltage-side smoothing capacitor, then turning on the negative-side relay, and further charging the branch-side smoothing capacitor by the DC/DC converter before turning on the branch relay. When an abnormality occurs in the DC/DC converter, the system startup is performed by turning on the positive-side relay of the system main relay and the branch relay, and turning on the precharge relay to charge the high-voltage-side smoothing capacitor and the branch-side smoothing capacitor, and then turning on the negative-side relay.",
