Abstract

The invention relates to the technical field of control and application of new energy sources, and in particular relates to a discontinuous power supply, a battery management system and a discontinuous power supply system, wherein the discontinuous power supply system comprises a battery pack, a discontinuous power supply and a battery management system which are correspondingly connected. Compared with the prior art, the discontinuous power supply, the battery management system and the discontinuous power supply system have the advantages that through the communication between the discontinuous power supply and the battery management system, the use of a switch tube in the battery management system is cancelled; the detected running parameter of the battery pack is sent to the discontinuous power supply through uploading data by the battery management system and then the charge / discharge parameter of the battery pack is adjusted by the discontinuous power supply; the connection between the battery pack and the discontinuous power supply is not needed to be cut off so that the possibility of sudden power failure caused by the cut-off of the switch tube on a main circuit of the battery management system is greatly reduced; and the response speed is high and no back load power failure is caused, so that the reliability and the efficiency of the whole system are simultaneously improved.

Description

technical field

[0001] This application relates to the technical field of new energy control and application, in particular to an uninterruptible power supply, a battery management system and an uninterruptible power supply system. Background technique

[0002] At present, the technology of battery charging by uninterruptible power supply has been widely used, but the charging, discharging management and energy management of the battery pack of the energy storage system are a difficult point in the management of the energy system.

[0003] In the prior art, uninterruptible power supply systems are composed of discrete uninterruptible power supplies and battery packs; the application of lithium batteries is only the addition of lithium battery management systems (BMS) on the basis of lithium batteries, and it is still Independent components, charge and discharge management of the battery, and energy management of the battery are all obtained by the simple estimation of the b...
