4. A power feeding control method which is performed using a power feeding control device for controlling a power feeding system,
the power feeding system including
a plurality of power supplies feeding power to a load,
a connection state switching unit configured to selectively connect or disconnect each of the plurality of power supplies and the load individually, and
an external power feeding unit which is connected in parallel with the load and feeds power to the load,
the power feeding control method comprising:
increasing supply voltage from the external power feeding unit to the load before the connection state switching unit starts switching of a connection state between each of the plurality of power supplies and the load, and
decreasing the supply voltage from the external power feeding unit to the load after the connection state switching unit switches the connection state between each of the plurality of power supplies and the load,
wherein:
increasing supply voltage from the external power feeding unit to the load until a current value of supply current from the plurality of power supplies to the load becomes zero, or until the current value of the supply current from the plurality of power supplies to the load is lowered to a predetermined value before the connection state switching unit starts switching of the connection state between each of the plurality of power supplies and the load, and
switching the connection state between each of the plurality of power supplies and the load by the connection state switching unit after the current value of the supply current from the plurality of power supplies to the load becomes zero, or after the current value of the supply current from the plurality of power supplies to the load is lowered to the predetermined value.
