Power supply system, power supply plate and electronic equipment

A power supply system comprising:

• electronic equipment adapted to control power supply based on battery identification information from a battery installed in a battery housing section;
• and
• a power supply plate, the power supply plate including
• a plate main body installed in the battery housing section of the electronic equipment, and
• a cable, a first end of which is connected to the plate main body and a second end of which is led through a lead-out hole of the battery housing section out of the electronic equipment, the second end also having a connector formed thereon which is connected to a power source, wherein
• power is supplied from the power source connected to the connector of the power supply plate to the electronic equipment, wherein
• the plate main body of the power supply plate has an information output section adapted to read identification information of the power supply plate from a storage medium and output the information to the electronic equipment in which the plate main body is installed, wherein
• the electronic equipment has an authentication process section and a control section, wherein
• the authentication process section is adapted to determine, based on power supply plate identification information from the information output section of the plate main body and battery identification information from the battery, which of the battery and the plate main body is installed in the battery housing section, and wherein
• the control section is adapted to control power supply from either the battery or the power supply plate according to the authentication result of the authentication process section.
