Energy storage type lithium battery pack power system

Abstract

The invention relates to an energy storage type lithium battery pack power system which comprises a rectifier (2), wherein one end of the rectifier (2) is connected with a lithium battery pack (3), the other end of the rectifier (2) is connected with a current supply device (1), one end of the lithium battery pack (3) is connected with a convertor (4), an inverter (5), a conversion switch (8), an output switch (9) and a load (13) in series, one end of the lithium battery pack (3) is connected with a display control module (7) by a control driving module (6), and one end of the control driving module (6) is connected with the inverter (5) and the output switch in parallel. The system provided by the invention can be used for collecting spare power energy of power devices when the power devices are in a spare state, can be used for automatically charging during a power down-peak period at night, can be used for releasing the power energy for power supply during power on-peak, and is low in cost, low in maintenance rate and convenient to maintain.

Description

technical field [0001] The present invention relates to the field of power supplies, in particular to a lithium battery power supply system, and more specifically to an energy storage type lithium battery pack power supply system. Background technique [0002] The application fields of lithium batteries are mainly communication (Communication), computer (Computer), consumer electronics (Consume) and other product fields. In the application fields of high-power and large-capacity batteries such as electric vehicles and grid energy storage, due to technical costs and other reasons, lithium batteries The promotion and application of has not yet been carried out on a large scale. The development needs of consumer electronics, electric vehicles and electric energy storage will further promote the progress of lithium-ion battery technology, and the development of high-energy lithium-ion batteries will be the most important research and development direction of lithium-ion battery ...

AI Technical Summary

Problems solved by technology

[0003] Although there are many kinds of lithium batteries on the market, so far, there is no practical multifunctional intelligent lithium battery pack power system on the market, which can automatically collect new energy devices such as solar silicon crystal panels and wind energy at leisure. The spare electric energy and the automatic use of low-valley electricity charging in the evening are integrated, and then the electric energy is automatically released at the peak time. The application of this product can achieve energy saving and money saving. Today, when the government is vigorously promoting low-carbon energy saving, it has a broad market promotion prospect.
