New energy power supply system

Abstract

The invention relates to the technical field of power supply, and discloses a new energy power supply system, which comprises a conversion power generation module, a standby power generation module, a power storage module, a power grid module, a power quality evaluation module, an identification module for identifying the power generation quality of a target module and a switching module for cutting off the power connection of the target module, if the conversion power generation module breaks down, the diesel power generation module can continue to supply electric energy, and continuous supply of the electric energy is further guaranteed; in addition, the power storage module can store redundant electric quantity and supply electric energy temporarily when the conversion power generation module and the standby power generation module fail, so that power shortage shutdown of the power load is avoided comprehensively. The electric energy evaluation module can automatically evaluate the power supply quality of the solar power generation module or the wind power generation module or even the commercial power supply module, and can drive the switching module to disconnect the solar power generation module from the power grid module, thereby preventing the solar power generation module from generating adverse effects on an electricity load.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a new energy power supply system. Background technique [0002] At the current stage, my country has begun to vigorously develop new energy, such as new energy vehicles. More and more policy orientations directly point to new energy vehicles, which has made domestic new energy vehicles develop in a blowout manner in recent years. The system presents a rigorous test. [0003] At present, the charging piles of new energy vehicles have multiple versions with different powers according to their charging speed. And higher current will have an impact on the battery system of the new energy vehicle. Moreover, due to the generally short battery life of new energy vehicles at present, more charging and battery life are required during long-distance travel, so this also puts forward certain requirements for the working reliability of the charging piles of new energy vehicles. Theref...

Problems solved by technology

[0003] At present, the charging piles of new energy vehicles have multiple versions with different powers according to their charging speeds. The higher the power, the faster the charging speed, but relatively higher requirements for charging safety, large voltage fluctuations and higher current will have an impact on the battery system of new energy vehicles

Moreover, since the current new energy vehi
