Apparatus and method for updating remote standalone firmware

A method, comprising:

• determining, by a micro-controller, that an updating device is inserted in at least one charging slot on a charging device;
• responsive to the determining, by the micro-controller, executing instructions stored in a second section in a firmware of the charging device;
• switching, by the micro-controller, to an updating mode;
• and
• updating instructions stored in a first section of the firmware, wherein the first section is configured to store charging instructions executed by the charging device, the updating comprising:
• retrieving, by the micro-controller, at least one of a charging device type and a firmware version from a non-volatile memory of the updating device,
• comparing, by the micro-controller, the charging device type with information stored in the first section, and if there is a match, comparing the firmware version with information stored in the first section,
• if the firmware version is later than a version retrieved from the first section, retrieving, by the micro-controller, information from the updating device and updating the first section with information retrieved from the updating device.
