Lithium battery bidirectional inverter energy storage power device

Abstract

The invention relates to a lithium battery bidirectional inverter energy storage power device, which comprises a device shell, and is characterized in that a lithium battery component is arranged in the device shell, wherein an output end of the lithium battery component is connected with an input end of an LCD (Liquid Crystal Device) electric quantity display component; and an output end of the LCD electric quantity display component is connected with an input end of a bidirectional inverter. Meanwhile, a loop between an output end of a charging module of the bidirectional inverter and the input end of the lithium battery component is provided with a charging switch; a loop between an input end of an inverter circuit module of the bidirectional inverter and an output end of the lithium battery component is provided with a discharge switch; and the bidirectional inverter is provided with a mains supply input port and an inverter output port. Thus, over-charging, over-discharging, over-current and over-high temperature can be prevented, and the safety in use is guaranteed. By using modularized design, the lithium battery bidirectional inverter energy storage power device has a small integral size and is suitable for energy storage power systems of medium and small-sized enterprises and household power systems.

Description

technical field [0001] The invention relates to a power supply device, in particular to a lithium battery bidirectional inverter energy storage power supply device. Background technique [0002] More and more electrical products appear in people's lives, and the demand for electricity in the whole society is increasing. During the peak period of electricity consumption or when the power supply equipment is damaged due to irresistible external factors, such as earthquakes, typhoons, tsunamis, etc., it will lead to insufficient power supply or power outages, seriously affecting people's production and life. The current backup power system is mainly aimed at data information equipment such as personal computers, servers, and storage devices to prevent sudden power failures, and the contents of the internal storage are too late to be saved on storage devices such as hard disks, resulting in data loss. It mainly includes UPS (Uninterrupted Power Supply), SPS (Standby Power Suppl...
