Embodiment Construction

[0024] Further detailed description will be made below in conjunction with the accompanying drawings and preferred embodiments.

[0025] see Figure 1 to Figure 5 , a building distributed energy storage power supply system, including a host computer G4, a power supply system G1, a building electrical equipment G3, and a DC charger G2. The power supply system includes a main power supply system battery cabinet 1 and an optional battery cabinet. This implementation In the example, there are two optional battery cabinets, but not limited thereto. When charging, the DC charger uses the mains power to supplement electric energy for the power supply system; when supplying power, the power supply system outputs electric energy for the electrical equipment of each building to maintain its normal operation.

[0026] The battery cabinet of the main power supply system is equipped with a main power supply 2, a controller, a battery management system, a high-voltage control box 3, a DC c...

Abstract

A building distributed energy storage power supply system comprises an upper computer, a power supply system, building electric equipment and a direct-current charger, and the power supply system comprises a main power supply system battery cabinet and at least one optional battery cabinet. A main power supply, a controller, a battery management system, a high-voltage control box, a direct-currentcharging socket, an inverter power supply, an isolation transformer and a power supply switch are arranged in the main power supply system battery cabinet, the high-voltage control box comprises a charging switch, a discharging switch and a charging switch, and the discharging switch is controlled by the battery management system. The battery management system is in communication connection withthe controller, the main power supply and the optional power supply, and the controller is in communication connection with the upper computer. And the main power supply system battery cabinet and theoptional battery cabinet are mounted in a distributed manner. The system has extremely high electric energy storage capacity, the battery cabinets are distributed in different machine rooms, safety is improved, the independent frame type battery cabinet body structure is flexible and changeable in installation, and production efficiency and field installation efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of building power supply and energy storage, and in particular relates to a building distributed energy storage power supply system. Background technique [0002] At present, solar energy and batteries are the main methods of building energy storage and power supply. Solar energy is energy-saving and environmentally friendly, has high safety, long service life and is maintenance-free. However, solar panels have higher requirements for location and installation, and are suitable for buildings on the top floor or one or two floors. Buildings, buildings in the middle of the floor are particularly difficult to meet the emergency power supply demand, at this time, the battery power supply solution was conceived. There are many types of batteries, but the batteries suitable for building energy storage are mainly lithium iron phosphate batteries, ternary lithium batteries, and lead-acid batteries. Lead-acid batter...
