A vehicle and related system and monitoring method are provided for detecting insulation loss on one side of a power converter. In one embodiment, a method involves monitoring a normalized voltage input to a power conversion module coupled to a motor, in response to the normalized voltage exceeding a diagnostic activation threshold, determining a first number of instances for which a range between consecutive extremums of the normalized voltage exceeds an insulation loss range threshold within a diagnostic time window, and automatically initiating a remedial action when the first number is greater than the insulation loss detection threshold.
提供了用于检测功率转换器的一侧上的绝缘损失的车辆和相关系统以及监测方法。方法涉及监测输入到联接到电动机的功率转换模块的归一化电压,响应于归一化电压超过诊断激活阈值,确定在诊断时间窗口内归一化电压的连续极值之间的范围超过绝缘损失范围阈值的实例的第一数量,以及当第一数量大于绝缘损失检测阈值时自动启动补救动作。
