A power distribution unit for a vehicle including an enclosure and power distributing means for distributing electrical power between a battery and a load application, the enclosure including an external casing and an internal casing having a faceplate and a mounting plate, the mounting plate having upper dielectric partitions protruding upward from a top face of the mounting plate, and the power distributing means being mounted on the mounting plate, wherein the upper dielectric partitions are configured to both maintain a separation between different voltage groups and define an insulating barrier between components of the power distributing means, the internal cartridge is configured to be inserted into the external casing, and the enclosure is configured to be sealed from an external environment.

Sealed power distribution unit for an electrical power distribution system

The present invention is notably directed to methods for estimating a degradation of an electronically controlled electro-mechanical switch. The methods comprise determining a change of state of the contactor. They also comprise, computing, for each determined change of state, a wear increment Wof the contactor by: identifying a wear coefficient using a mapping between a last measured current through the contactor and a current range associated with a given wear coefficient; computing the actual wear Wof the contactor by adding the computed wear increment Wto a former known wear Wof the contactor.

Direct current contactor wear tracking

The present invention is notably directed to methods and systems for protecting a pre-charge circuit. The present invention is further directed to related computer-implemented program product. The method comprises monitoring the current flowing through the current limiting device, calculating the energy loading of the current limiting device over time, and managing the system state to prevent damaging operation of the pre-charge circuit.
