Abstract: In at least one embodiment, a busbar assembly for a vehicle is provided. The assembly includes a printed circuit board (PCB), a first plate, a second plate, and a third plate. The first plate supported on the PCB and is configured to enable a first current to flow in a first direction. The second plate is supported on the PCB and includes a first portion positioned below the first plate to enable a second current to flow in a second direction. The third plate is on the PCB and is positioned below the second plate to enable the first current to flow in the first direction. The second current that flows through the second plate is increased through an effective cross-section of the second plate when the flow of the second current in the second direction is different than the flow of the first current in the first direction.

Abstract: An on-board battery charging system for a plug-in electric vehicle has a charging unit for charging a high-voltage battery and a controller for controlling and managing current flow used to support charging related operations for the high-voltage battery. The controller may detect a connection between the on-board battery charging system and electric vehicle supply equipment (EVSE) and is configured to enter a sleep mode when a control pilot signal from the EVSE is either absent or indicative of a delayed charge mode. The charging system may include a wake-by-control pilot circuit operable to wake the controller from the sleep mode when the control pilot signal is detected and when the control pilot signal transitions from a non-zero static DC voltage to an active PWM signal.

The vehicle interface may include a noise compensation configured to facilitate compensating for noise within the reference signal resulting from the reference circuit. The vehicle interface may be configured to adapted to common mode interference and other influences resulting from connections between the vehicle interface and EVSE being referenced to earth ground and connections between the vehicle interface and other vehicle electronics being reference to a vehicle chassis ground.

Abstract: A safety guardian is operable to facilitate notifying an Electronic Vehicle Supply Equipment (EVSE) system whether a vehicle charging system is ready to accept energy. The safety guardian may be configured to facilitate control of a vehicle interface used to provide a reference voltage to the EVSE reflective of whether the charging system is ready to accept energy. The guardian may control the vehicle interface in the absence of a suitable control signal from the vehicle charging system in order to ensure the EVSE is notified when the vehicle charging system is not ready to accept energy.
