PROBLEM TO BE SOLVED: To make an electric wire for vehicle thin according to the reduction of a required current value by increasing a voltage. SOLUTION: An electric wire for a low voltage system to which, a maximum voltage of 14 V or 28 V is impressed, and an electric wire for a high voltage system to which, a voltage higher than the voltage impressed to a bus bar of the low voltage system but lower than 200 V, is impressed, are installed. Electric devices requiring high power of 250 W or more are connected to the electric wire of the high voltage system and the diameter of the electric wire is made thin by reducing the current volume flowing at the electric wire of the high voltage system. In comparison with the case of connecting electric devices requiring high power to the electric wire of the low voltage system, the size of the electric wire is reduced by 30%-60%. |
