Abstract
Disclosed are power supply methods in a power over data lines (PoDL) system for a vehicle network. An operation method of a power sourcing equipment (PSE) for power supply to a powered device (PD) comprises measuring an input voltage applied to the PSE; detecting a low voltage state in which the input voltage is lower than a low voltage detection reference voltage; determining whether the low voltage state is a transient voltage drop state; and entering a settle-sleep step when the low voltage state is not the transient voltage drop state, and stopping the power supply between the PSE and the PD while maintaining a link between the PSE and the PD when the low voltage state is the transient voltage drop state.
