Abstract

The invention relates to the technical fields of new energy control and application, in particular to a wind-light complementary intelligent charge-discharge controller, a battery management system and a wind-light complementary intelligent charging system. The wind-light complementary intelligent charging system comprises a battery pack, the wind-light complementary intelligent charge-discharge controller and the battery management system which are correspondingly connected. The wind-light complementary intelligent charging system is communicated with the battery management system through the wind-light complementary charge-discharge controller. Compared with the prior art, a switch tube in the battery management system is removed, detected running parameters of the battery pack can be uploaded to report the wind-light complementary intelligent charge-discharge controller, charge-discharge parameters of the battery pack can be adjusted by the wind-light complementary charge-discharge controller, the connection between the battery pack and the wind-light complementary intelligent charge-discharge controller is not broken, and abnormal situations of system proruption outage caused by breaking a main road switch tube of the battery management system are greatly reduced. The wind-light complementary intelligent charging system is high in reaction speed, cannot cause rear end load outage and simultaneously improves reliability and efficiency of the whole system.

Description

technical field

[0001] This application relates to the technical field of new energy control and application, in particular to a wind-solar hybrid intelligent charge-discharge controller, a battery management system and a wind-solar hybrid intelligent charging system. Background technique

[0002] At present, the technology of solar energy and wind energy to charge batteries has been widely used, but the management of charging, discharging and energy management of battery packs in energy storage systems is a difficult point in the management of energy systems.

[0003] In the existing technology, wind and solar complementary and discharge energy storage systems are composed of discrete wind and solar complementary, discharge controllers and battery packs; the application of lithium batteries only adds lithium battery management on the basis of lithium batteries The battery management system (BMS) is still an independent component. The charging and discharging management of ...
