Abstract: The present invention involves an intelligent electrical energy management system device. The device includes a power supply module (2), a control module, a memory module, an input module, a clock module (12) for providing a real-time clock, a current detection module (8) for detecting the current flowing in electrical equipments (91, 92, 93, 9n), and an electronic controlled switch. The memory module, the input module, the clock module (12), the output terminals of the current detection module (8), and the control terminal of the electronic controlled switch are connected to the data terminals of the control module respectively. An external power supply supplies power to the electrical equipments (91, 92, 93, 9n) via the electronic controlled switch and the current detection module (8). The power supply module (2) is connected to the external power supply and provides power to each module.
