Management device for battery charging energy source of solar off-grid and grid-connected system

Abstract

The invention provides a management device for a battery charging energy source of a solar off-grid and grid-connected system, which is characterized by comprising a box body, a power supply network connecting pipe and a solar energy connecting pipe, wherein the box body comprises a power supply network voltage processing assembly, a solar voltage processing assembly, a charging management assembly and an alarm display assembly, a first adapter is arranged in the power supply network connecting pipe, and a second adapter is arranged in the solar energy connecting pipe. The charging management assembly provided by the invention performs optimization management on an energy source for charging the battery, and when the power supply network is in a power utilization peak period, the reasonable source can still be used for charging the battery, so that a user is prevented from paying too much electric charge. The first adapter and the second adapter provided by the invention are detachable assembly parts, can be fixedly mounted during assembly, and can be detached and replaced when being damaged and needing to be replaced.

Description

technical field [0001] The invention relates to the technical field of circuit equipment, in particular to a management device for charging energy sources of batteries by a solar off-grid system. Background technique [0002] With the progress and development of society, people's demand for electricity continues to increase. At present, many areas have insufficient power supply from the power supply network, and frequent power outages. The emergence of new energy has reduced the power supply pressure of the power supply network. In solar energy When generating electricity, the photovoltaic system needs to have two functions of off-grid and grid-connected operation. [0003] The existing solar off-grid system manages the source of charging energy for the battery as follows: use solar energy first, when the solar energy is sufficient, the charging energy is completely taken from the solar energy; when the solar energy is insufficient, the power supply network provides power su...

Problems solved by technology

[0003] The existing solar off-grid system manages the source of charging energy for the battery as follows: use solar energy first, when the solar energy is sufficient, the charging energy is completely taken from the solar energy; when the solar energy is insufficient, the power supply network provides power supply supplement , at this time, the solar energy and the power grid provide charging energy for the battery at the same time; It will obtain energy from the power supply network to charge the battery, no matter whether the power supply network is in the peak period of power consumption at this time, it is easy to overload the voltage of the power supply network and cause power outages, and when the power supply network is in the peak period of power consumption, the electricity price is high, and users need to The charging fee paid is also high, so the energy source for battery charging needs to be optimized and managed. In the process of charging the battery, charging voltage that is too high or too low will cause certain damage to the inside of the battery. Therefore, the optimization of charging voltage Management is also critical
