Extensible modular lithium ion battery uninterruptible power supply

Abstract

The invention relates to an extensible modular lithium ion battery uninterruptible power supply and belongs to the power supply technical field. According to the extensible modular lithium ion battery uninterruptible power supply, a host machine module, a battery charging switching module and a battery module which are connected with one another are arranged in a cabinet; a rectification module, an inversion module and a control module are connected with one another so as to form the host machine module; the control module intelligently manages a system and switches program execution; the host machine module, the battery charging switching module and the battery module are modular standard 2U cases; the battery module is a battery module using lithium iron phosphate batteries; the battery module using the lithium iron phosphate batteries has a cascading function and is under switching management of a battery switching management module, so that a customer can select an extensible number of batteries according to standby time requirements so as to realize on-load time redundancy. The extensible modular lithium ion battery uninterruptible power supply of the invention has the advantages of environmental friendliness, high volume energy ratio, high weight ratio and convenience in movement, and can realize high availability, high adaptability and high management performance of the on-load time redundancy.

Description

technical field [0001] The invention belongs to the technical field of power supplies, in particular to an expandable modular lithium-ion battery uninterruptible power supply. Background technique [0002] At present, the UPS power supply uses a valve-regulated sealed lead-acid battery as a reserve battery. With the continuous improvement of environmental protection requirements and the improvement of the intensive degree of computer rooms, the demand for UPS is further improved. The uninterruptible power supply generated by lithium-ion batteries effectively overcomes the large size, heavy weight, and inconvenience of traditional lead-acid battery uninterruptible power supplies. Short lifespan and great environmental pollution. [0003] However, the existing lithium-ion battery uninterruptible power supply is only a simple replacement of the traditional UPS power storage battery. The non-modular uninterruptible power supply occupies a large space, is not convenient for inst...

With the continuous improvement of environmental protection requirements and the improvement of the intensive degree of computer rooms, the demand for UPS is further improved. The uninterruptible power supply generated by lithium-ion batteries effectively overcomes the large size, heavy weight, and inconvenience of traditional lead-acid battery uninterruptible power supplies. Short life and serious environmental pollution

[0003] However, the existing lithium-ion battery uninterruptible power supply is only a simple replacement of the traditional UPS power storage battery. The non-modular uninterruptible power supply occupies a large space, is not convenient for installation and maintenance, and the initial construction and maintenance costs are high; at the same time, the battery It is not scalable, cannot realize load time redundancy, and cannot meet the requirements of different customers for load time redundancy under different demand conditions; the availability, adaptability and management are not high and the economy needs to be improved, which can no longer meet the needs of green data centers Technical issues such as fast-growing demands that require high-integration UPS system support
