CONTROL DEVICES AND PROGRAM

WIPO Patent Application WO/2024/084891

A1

These control devices (50, 51) are applied to a system comprising: a rotary electric machine (20) which has windings (21); an inverter (30) which has upper and lower arm switches (SWH, SWL) that are electrically connected to the windings; and a battery (40) which is electrically connected to the inverter. The control devices determine a charge limit value at which the battery enters a fully-charged state, and embodies a regenerative drive control by which the rotary electric machine functions as a generator under the condition that a charging parameter indicating the charge state of the battery is lower than the charge limit value. The control device comprises: a charge determination unit which determines whether the charging parameter has a value equal to or greater than a charge determination value that is lower than the charge limit value and whether the regenerative drive control is embodied; and a control unit which, when the charging parameter is equal to or greater than the charge determination value and the regenerative drive control is embodied, performs a control to suppress charging of the battery through the regenerative drive control.
