<p>In an electric vehicle in which a high voltage battery supplying electric power to an electric motor generating power to drive a drive wheel and a low voltage battery supplying electric power to an accessory are mounted in a vehicle body, a breaker (62) is provided in a circuit (74) of a high power system linked to the high voltage battery (36); manual connection-disconnection means (71) for allowing switching between connection and disconnection of a circuit (75) of a low power system linked to the low voltage battery (40) to be performed by a manual operation is provided in the circuit (75) of the low power system; a relay switch (63, 64) which is capable of performing switching between connection and disconnection of the circuit) (74) of the high power system by being supplied with electric power from the circuit (75) of the low power system, and which interrupts the circuit (74) of the high power system when the circuit (74) of the low power system is interrupted is provided on the circuit (74) of the high power system; and touch prevention means allows the breaker (62) to be touched only when the circuit (75) of the low power system is interrupted by using the manual connection-disconnection means (71). Accordingly, it is possible to make a work procedure in the maintenance of a breaker of a high power system easier to follow.</p> |
