A management device for battery charging energy source of solar off-grid system

Abstract

The present invention proposes a management device for charging energy sources of batteries by a solar off-grid system, which is characterized in that it includes a box body, a power supply network connection pipe and a solar energy connection pipe, and the box body includes: a power supply network voltage processing component and a solar voltage processing component , a charging management component and an alarm display component, a first adapter is provided in the connecting pipe of the power supply network, and a second adapter is provided in the connecting pipe of the solar energy. The charging management component proposed by the present invention optimizes the energy source for battery charging. When the power supply network is in the peak period of electricity consumption, a reasonable source can still be used to charge the battery to avoid excessive electricity bills paid by the user. The first adapter and the second adapter proposed by the present invention are detachable assembly parts, which can It is fixed and installed during assembly, and it is removed and replaced when it is damaged and needs to be replaced.

Description

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

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
