    • A power supply unit includes a battery, a motor which is driven by the battery, an electric power converting device which is provided between the battery and the motor, a simulated electric leak generating device which generates an electric leak state between the battery and a vehicle body, and an electric leak detecting device which detects a simulated electric leak. A diagnostic system which performs a diagnosis of operating performance of the electric leak detecting device includes an opening/closing device which connects/disconnects the electric power converting device to/from the battery, and an opening/closing detecting device which detects opening/closing of the opening/closing device and which outputs a result of detection to the simulated electric leak generating device and the electric leak detecting device. When opening/closing of the opening/closing device is detected by the opening/closing detecting device, both generation of a simulated electric leak and detection of an electric leak are retried.
    • 电源单元包括电池,由电池驱动的电动机,设置在电池和电动机之间的电力转换装置,在电池和车辆之间产生电气泄漏状态的模拟泄漏产生装置 身体和检测模拟电泄漏的漏电检测装置。 执行泄漏检测装置的操作性能的诊断的诊断系统包括将电力转换装置与电池连接/断开的开闭装置,以及检测开关的开闭检测装置 所述开闭装置将检测结果输出到所述模拟泄漏检测装置和所述漏电检测装置。 当打开/关闭检测装置检测到打开/关闭装置的打开/关闭时,重新产生模拟泄漏和检测电气泄漏。
