PROBLEM TO BE SOLVED: To provide an LDC (Low voltage DC-DC converter) controller for an electric vehicle, in which an LDC brings itself into a state that the LDC operates when at least one other electric component interlocking with not only an IGN (ignition) signal but also the LDC is in an ON state, and in which the LDC recognizes that each of all other electric components interlocking with the LDC is in an OFF state and operates itself in a power OFF state when each of all the electric components interlocking with the LDC is in the OFF state.SOLUTION: An LDC controller for an electric vehicle interlocked with a start part, an LDC, and a load device includes: a CAN (Controller Area Network) communication part communicating with the load device through a CAN bus; and a control part outputting a power control signal to the LDC, and transmitting/receiving data including state information of the load device to/from the LDC. The control part outputs a power ON control signal to the LDC if data are present in the CAN bus when an IGN signal state information of the start part is in an OFF state, and outputs a power OFF control signal to the LDC if data are absent in the CAN bus when the IGN signal state information of the start part is in an ON state. |
