Abstract

The invention discloses a gasoline-electricity hybrid power supply system and a control method of the gasoline-electricity hybrid power supply system, relates to an automatic power supply unit and a control method for realizing the automatic power supply unit, and aims at solving the problems of single power supply mode and short service life of the existing power supply unit. The power supply system comprises a diesel generating set, three alternating-current contactors, a rectifier, an AC / DC (alternating current / direct current) input power module, a BMS (Battery Management System), two lithium ion battery packs, a main controller and a diesel engine controller, wherein the diesel generating set and mains supply are used for supplying power to the two lithium ion battery packs and load simultaneously by adopting a double-input power supply mode according a principle that the mains supply is preferentially used, and when the diesel generating set and the mains supply do not work, the lithium ion battery packs are used for supplying power to the load; when the capacities of the lithium ion battery packs are smaller than a set value, the diesel generating set is started to supply power to the load and charge the lithium ion battery packs simultaneously, and finally stops working when full charging is achieved. The technology is used for the power supply system.

Description

technical field [0001] The invention relates to an automatic power supply device and a control method of the automatic power supply device. Background technique [0002] At present, the known power supply systems all adopt a single power supply of a diesel generator set, or a mixed power supply of a diesel generator set and a lead-acid battery. The disadvantage of using diesel generator set for power supply is obvious. The generator set runs continuously. In the case of low current power supply, it not only wastes diesel resources, but also reduces the service life of diesel generator set. However, the disadvantage of using diesel generator set and lead-acid battery hybrid power supply is that the charging time of lead-acid battery is long, and the power generation time of diesel generator set is also extended. Contents of the invention [0003] The purpose of the present invention is to solve the problem of single power supply mode and short service life of the existing ...
