Abstract: A multiphase converter system includes a multiphase converter in which a plurality of converters are connected in parallel; a cooler in which a cooling medium flows so as to cool the multiphase converter; a temperature sensor configured to measure a temperature of the cooling medium; and a controller. The controller is configured to drive the converter for n phase or the converters for n phases when a target output of the multiphase converter is lower than a prescribed output threshold and the temperature of the cooling medium falls within a prescribed temperature range, and to drive the converters for m phases when the target output is lower than the prescribed output threshold and the temperature of the cooling medium is lower than the prescribed temperature range, m being larger than n.

Abstract: A connector housing comprises a mating portion including a plurality of mating hoods that are arranged in a width direction on a front side of the connector housing that is configured to be mated with a mating connector and a rear structure portion disposed posterior to the mating portion. The rear structure portion includes a plurality of structure parts each disposed between two mating hoods adjacent to each other of the plurality of mating hoods and a plurality of notches each disposed between two structure parts adjacent to each other of the plurality of structure parts.

Abstract: A voltage monitoring system includes a first connection line group connected to input terminals of a first monitoring IC, a first connector configured to connect or disconnect connection lines of the first connection line group to or from connection points each arranged on a side of a positive electrode or negative electrode of any one of battery cells of a first battery group, a second connection line group connected to input terminals of a second monitoring IC, and a second connector configured to connect or disconnect connection lines of the second connection line group to or from connection points arranged on a side of a positive electrode or negative electrode of any one of battery cells of a second battery group. The first monitoring IC is electrically isolated from the second monitoring IC. The first connection line group is electrically isolated from the second connection line group.

Abstract: A connector includes: a first connector terminal to which a first electric cable is to be connected; a second connector terminal to which a second electric cable is to be connected; a sidewall that surrounds the first connector terminal and the second connector terminal; a protection cover; and an interlock mechanism. The interlock mechanism includes an interlock connector and an interlock pin. The interlock connector is disposed between the first connector terminal and the second connector terminal, and the interlock pin is provided at the protection cover and is positioned such that the interlock pin is inserted into the interlock connector when the protection cover is attached to the sidewall.
