CHARGER

摘要

In a charger, according to one possible configuration, a pulse signal from a DC/DC converter control unit and a signal from a main safety control unit are applied to a mask. The mask outputs a result of an AND operation on the signals to a gate drive unit and a checking unit. The main safety control unit temporarily changes the output signal from an H level to an L level at a predetermined timing in a state where no information indicating a fault of the charging operation is acquired, and holds the output signal for a predetermined time. When a pulse signal is output without the output of the mask switching to an L level during this time, the checking unit outputs an H level signal. When acquiring the H level signal from the checking unit, the main safety control unit determines that the mask is not operating normally.

主权项

1. A charger comprising:
a power converter configured to convert alternating current power into direct current power and to perform a charging operation of supplying the direct current power to a vehicle-mounted battery; a forced stop circuit that, when operating normally, forcibly causes the power converter to stop the charging operation in response to receiving a forced stop signal; and a controller configured to perform a confirmation of whether or not the forced stop circuit is operating normally and to output information indicating a result of the confirmation.
