PROXIMITY DETECTION CIRCUIT FOR ON-BOARD VEHICLE CHARGER

The invention discloses a proximity detecting circuit of a vehicle charger. The proximity detection circuit suitable for use with an on-board vehicle charger, such as but not limited to the type of chargers used within hybrid and electric vehicles, to facilitate current conservation during period of time when it is unnecessary or otherwise undesirable. The on-board charger can test for connectionof a cordset or other electrical connection used to connect the on-board charger to a charging station or other current source. The on-board charger can be used to detect two different cordsets or vehicles using different charging circuitries. 本发明公开了车载充电器的接近检测电路。一种适合与车载充电器一起使用的接近检测电路，例如但不限于混合动力车辆和电动车辆中使用的充电器类型，以便于在不必要的或不希望的时间段内节约电流。车载充电器可以测试用于将车载充电器连接到充电站或其他电流源的电线组或其他电连接的连接。车载充电器可用于检测使用不同充电电路的两种不同的电线组或车辆。
