Combined energy storage power station

Abstract

The invention relates to the technical field of battery packs, and discloses a combined energy storage power station comprising the following parts: an inverter power supply comprising a first inverter and a first interface electrically connected with the first inverter and suitable for electric energy input, wherein the first interface being connected with a battery pack; a second inverter and asecond interface electrically connected with the second inverter and suitable for electric energy input; the second inverter is suitable for being connected with the first inverter in parallel so thatthe AC voltage output by the two inverters can be output in parallel to increase the power station output power. The combined type energy storage power station has the advantages that the combined energy storage power station is high in output power, capable of being connected with a plurality of tool battery packs to be discharged simultaneously with the battery pack, long in discharging time and high in expandability; and the idle tool battery packs of the electric gardening tools can play a greater role.

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] The energy storage power station mainly includes a built-in battery, an inverter and an electronic control system. The battery can be charged from the mains, solar energy or a generator. The inverter can convert the DC power of the battery into AC power for various electrical appliances. Of course, it can also Configure DC output interfaces of various voltages. 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, self-provided power for yachts and vehicles, mobile communication base stations, and many other occasions. However, the energy storage power stations on the market have a single structure and function, and the battery capacity is limited. When the battery capacit...

Problems solved by technology

[0004] In order to expand the capacity of the energy storage power supply, one method is to connect multiple battery packs and stack multiple battery packs to increase the total capacity of the energy storage power station. In the case of charging the battery pack, the common power supply effect is not good, and unnecessary waste of electric energy is increased

Furthermore, in some cases, for some high-power electrical equipment, the output power of a single energy storage power supply is not enough to 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
