METHODS AND APPARATUS FOR DETECTING ELECTRICAL LEAKAGE IN A VEHICLE |
| 摘要 |
A vehicle includes a battery pack, an electric motor, and a contactor to electrically connect the pack and motor. The contactor is configured with a control circuit to electrically connect the pack and motor. The control circuit includes a leak detection sensor. The vehicle further includes a controller to output a leakage resistance associated with the pack. The leakage resistance is based on a voltage of the pack and a leak voltage detected by the sensor while the contactor is closed. |

1. A vehicle comprising:
a battery pack; an electric motor; a contactor configured to electrically connect the pack and motor; control circuitry for the contactor including a leak voltage detection sensor; and at least one controller programed to output a leakage resistance associated with a terminal of the pack based on a voltage of the pack and a leak voltage detected by the sensor while the contactor is closed. |
