Electronics unit with current sensing

摘要

A electronics unit operable to facilitate vehicle battery charging or other energy manipulation activities. The electronics unit may include a current sensor operable to determine an output current. The output current determination may be used as feedback or inputs to other electronics unit electronics, such as to facilitate battery charging related operations or other operations attendant to use of the electronics unit.

1. An electronics unit operable for use within a vehicle to rectify a three-phase, AC input to a DC output, the electronics unit comprising:
an assembly having:
i. conducting first, second, and third input terminals each operable to establish an electrical connection to one of three input busbars carrying the AC input;ii. conducting first and second output terminals each operable to establish an electrical connection to one of two first and second output busbars carrying the DC output;iii. a rectifier disposed between the input terminals and the output terminals, the rectifier having a plurality of switches operably connected between the input terminals and the output terminals to rectify the three-phase AC input to the DC output; a shunt operatively coupled between the first output terminal and the first output busbar; a current sensor operable to determine a current through the shunt; at least one printed circuit board (PCB) having control electronics operable to manage power distribution between the electronics unit and one or more vehicle subsystems based at least in part on the current measured by the current sensor; and a housing shaped to substantially enclose the assembly and each of the at least one PCB, the housing having a projection extending therefrom configured to supportively engage the shunt exterior to the housing.
