Abstract
Apparatuses and methods for implementing contactor opening and fusing strategies in a power distribution unit are disclosed, including a power distribution unit comprising: one or more contactors coupled to one or more charging systems; one or more active fuses in a circuit connecting the one or more contactors to a battery system; and a microcontroller configured to: receive one or more current values; determine whether the one or more current values meet a first set of predetermined current thresholds; in response to determining that the one or more current values meet the first set of predetermined current thresholds, trigger the one or more active fuses; determine whether the one or more current values meet a second set of predetermined current thresholds; and in response to determining that the one or more current values meet the second set of predetermined current thresholds, signal the one or more contactors to open.
