Power management system for a motor vehicle

A power management system for a motor vehicle, the motor vehicle comprising at least one energy storage device and at least one solar cell for generating electrical energy, said power management system being provided with a charging device which is designed to both charge the energy storage device with electrical energy from an external energy source and to supply an external consumer with electrical energy from at least one of the energy storage device and the solar cell, wherein:

• the charging device comprises a DC-DC converter, by means of which both a voltage of a direct current supplied from the external energy source to the energy storage device may be converted and by means of which a voltage of a direct current supplied from the energy storage device and/or the solar cell to the external consumer may be converted;
• and
• the charging device comprises an inverter and a rectifier, by means of which an alternating current supplied by the external energy source to the energy storage device may be converted into a direct current and by means of which a direct current supplied by the at least one of energy storage device and the solar cell to the external consumer may be converted from a direct current into an alternating current, characterised in that
• the power management system comprises a control apparatus by means of which an energy supply of the external consumer can be enabled by the charging device, and
• the control apparatus is configured to connect to at least one control device provided as a smartphone, by means of which an enable command to enable the charging of the external consumer can be transmitted to the control apparatus, wherein depending on the enabling of the energy supply to the external consumer the control apparatus unlocks a cover element for an electrical connection of the charging device to the external consumer, in particular a plug and/or a socket.
