Local area network power management device

Abstract

The invention relates to a power management device (1) integrating a network input (3); a first power interface (5) for critical loads of a local network; an islanding switch (7); a central controller (10); a network shaping inverter (14) configured to provide uninterruptible power to the critical loads: at least one battery (11); at least one bidirectional charging station (12) for electric vehicle (13) so that the industrial battery (11) can be used to charge the electric vehicle (13) and, when an electric vehicle (13) is plugged in with sufficient charge, a battery of the electric vehicle can be used to charge the industrial battery (11); so that the power management device can operate in an islanding mode in which the industrial battery (11) and / or the battery of the electric vehicle (13) supply the power interface (5).Figure for the abridged version: Fig 1.
