Combined energy storage power station

Abstract

The invention relates to the technical field of battery packs, and discloses a combined energy storage power station, which comprises an inverter power supply comprising a first inverter and a first interface electrically connected with the first inverter and suitable for electric energy input; the first interface is connected with a first battery pack, and a current limiting module circuit suitable for preventing mutual charging of batteries is arranged in the first battery pack; the power station also has a second inverter and a second interface that is electrically connected with the secondinverter and is suitable for electric energy input; the second inverter is suitable for being connected with the first inverter in parallel to increase the output power of the power station. The combined energy storage power station has the advantages that the combined energy storage power station is high in output power, long in discharge time and high in expansibility; different types of tool battery packs can be accessed, and the application range is wide; and idle tool battery packs of different types of electric gardening tools can be utilized.

Description

Technical field [0001] The invention relates to the technical field of battery packs, in particular to a combined energy storage power station. Background technique [0002] Energy storage power stations mainly include built-in batteries, inverters and electronic control systems. They can be charged from city electricity, solar energy or generators. The inverter can convert the battery’s DC power into AC power for use by various electrical appliances. Configure various voltage DC output interfaces. Portable energy storage power stations have a wide range of applications, such as: home or unit backup power, field operations, emergency power, disaster relief, outdoor life and travel, yachts and vehicles self-provided power, mobile communication base stations and many other occasions. However, the energy storage power station on the market has a single structure and a limited battery capacity. After the battery capacity is exhausted, it cannot continue to supply power to the electr...

AI Technical Summary

Problems solved by technology

[0004] In order to expand the capacity of the energy storage power station, the existing method is to increase the total capacity of the energy storage power station by connecting multiple battery packs and stacking multiple battery packs. The case of low battery pack charging makes the power supply effect not good, and increases unnecessary waste of electric energy

Furthermore, in some cases, for some high-power electrical equipment, the output power of a single energy storage power station cannot meet the requirements of the electrical equipment, and it is necessary to provide a higher power energy storage power station to meet the use requirements
