A power supply system for an electric vehicle for autonomous driving may be capable of stabilizing power supply to power electric parts and indoor parts even when short circuit occurs in one or more nodes by variously configuring an architecture circuit for power supply to the PE parts and the indoor parts using one or more switching elements and a short-circuit detector associated with the one or more nodes.

Power supply system for electric vehicle

In an embodiment a power supply system includes a low voltage DC/DC converter (LDC) configured to convert a high voltage into a low voltage, a main battery configured to be charged by the LDC and to supply power to a junction block divided into an essential load part and a general load part, a control block comprising a first power switch configured to control power between the LDC and the junction block, a second power switch configured to control the power between the main battery and the junction block, and a load switch configured to selectively cut off the power to the general load part and an auxiliary battery configured to selectively supply power to an auxiliary junction block.
