Problems solved by technology

[0004] However, in the case of dividing the power system of one vehicle into a high-voltage power system connected to a high-voltage battery and a low-voltage power system connected to a low-voltage battery, a technique is known in which high-voltage The disconnection and conduction of the power system, so the length of the wiring of the high-voltage power system is suppressed, and the enlargement of the switching circuit of the high-voltage power system is suppressed. However, fuses as circuit breakers are often installed in the circuits of the high-voltage power system. When it is repaired (replacement work), it is hoped that the repair work of the circuit breaker can be carried out without special attention

Abstract

The present invention provides an electric vehicle, which is equipped with a high-voltage battery for supplying electric power to an electric motor that outputs power for driving drive wheels, and a low-voltage battery for supplying electric power to auxiliary equipment, and is connected to the high-voltage battery (36). The circuit (74) of the high-voltage power system is provided with a circuit breaker (62), and the circuit (75) of the low-voltage power system connected to the low-voltage storage battery (40) is provided with a circuit breaker (75) that switches the circuit off and on through manual operation. The manual cut-off and conduction device (71) can switch the cut-off and conduction of the circuit (74) of the high-voltage power system through the power supply from the circuit (75) of the low-voltage power system and cut off the circuit (75) of the low-voltage power system The relay switch (63, 64) that cuts off the circuit (74) of the high-voltage power system is arranged on the circuit (74) of the high-voltage power system, and through the contact prevention device, only when the low-voltage power system is cut off by the manual cut-off and conduction device (71) Under the condition of the circuit (75), it is allowed to contact the circuit breaker (62). Thereby, it becomes easy to follow the work order at the time of maintenance of the circuit breaker of a high-voltage power system.

Description

technical field [0001] The present invention relates to an electric vehicle in which a high-voltage battery that supplies power to an electric motor that outputs power for driving drive wheels and a low-voltage battery that supplies power to auxiliary equipment are mounted on a vehicle body. Background technique [0002] Patent Document 1 discloses an electric two-wheeled vehicle that supplies electric power to a motor from a high-voltage battery such as 36V, and supplies electric power to a control unit (ECU) from a low-voltage battery such as 12V. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2006-182315 [0004] However, in the case of dividing the power system of one vehicle into a high-voltage power system connected to a high-voltage battery and a low-voltage power system connected to a low-voltage battery, a technique is known in which high-voltage The disconnection and conduction of the power system, so the length of the wiring of the high-voltage power s...
