Abstract
A vehicle power control method for jump-start uses a vehicle control system that includes a low voltage DC/DC converter for converting a voltage of a high voltage battery to a low voltage to be output and a junction box for connecting the low voltage DC/DC converter to an auxiliary battery and load. The vehicle power control method includes a jump-start preparation step in which when the auxiliary battery is in a discharge condition, a first relay, which connects or disconnects the junction box to or from the auxiliary battery, is turned off and a second relay, which connects or disconnects the junction box to or from a jump-start power supply connection terminal, is turned on; and a jump-start completion step in which, after a vehicle starts by a power inputted through the jump-start power supply connection terminal, the second relay is turned off, and the first relay is turned on.
