摘要： A fault detection method is disclosed for a motor vehicle charging system including a generator (14) and an electrical component (19) coupled to receive electrical current from the generator (14). In one embodiment, the method comprises sensing a first voltage at an output of the generator (14) and sensing a second voltage at the electrical component (19) and, if the first voltage and the second voltage differ by more than a predetermined amount, reducing or suspending output of electrical current from the generator (14). One advantage of the method disclosed herein is in its ability to diagnose a fault in an electrical connection at the output of a motor vehicle generator, where the fault manifests itself as a high resistance connection.
摘要翻译：公开了一种用于机动车辆充电系统的故障检测方法，该系统包括发电机（14）和耦合以接收来自发电机（14）的电流的电气部件（19）。在一个实施例中，该方法包括感测发电机（14）的输出处的第一电压并感测电气部件（19）处的第二电压，并且如果第一电压和第二电压差超过预定量，减少或暂停来自发电机（14）的电流输出。本文公开的方法的一个优点在于能够诊断机动车辆发电机的输出处的电连接中的故障，其中故障表现为高电阻连接。
