摘要:
A pre-charge circuit is disclosed for a vehicle including a battery and a load. The pre-charge circuit includes a time delay circuit configured to, in response to receiving power from the battery, generate a first voltage. The first voltage increases from a first value toward a second value. The pre-charge circuit includes a switch control circuit configured to, in response to the first voltage, provide a second voltage that follows the first voltage. The pre-charge circuit includes a switching circuit configured to selectively connect the battery to the load based on the second voltage and disconnect the load from the battery in response to the second voltage reaching a predetermined threshold value. The pre-charge circuit includes an output circuit configured to restrict an amount of power and inrush current that is provided from the battery to the load through the switching circuit.
