Problems solved by technology
However, this patent also has shortcomings, it only has two functions of "scheduled power supply" and "day and night judgment"
Since the charge and discharge limit of the battery is generally within the upper and lower limits of 10%, once the charge and discharge exceed this range, the battery will be damaged, and this patent lacks a control function, which cannot solve this problem, and the charging and discharging channel of the patent is single, which cannot reach Stable and reliable power supply

Embodiment Construction
[0036] The present invention will be described in detail below taking solar photovoltaic power supply and city power supply combined charging and discharging as an example.
[0037] Such as figure 1 , 2 As shown, the present invention is composed of a control circuit, a battery pack, and an AC / DC converter. The control circuit is composed of a pulse width modulation circuit, an overvoltage and undervoltage protection circuit, and a load overrun protection circuit; the battery pack is composed of four batteries connected in series. The AC-DC converter is a UPS inverter. When it is in the inverter state, it converts DC power into AC power, and it can convert AC power into DC power.
[0038] The pulse width adjustment circuit is connected with the mains power supply and the battery pack. The pulse width adjustment circuit limits the charging current of the mains power supply. When charging the battery, it can avoid damage to the battery due to excessive current and reduce the vo...

Description
technical field [0001] The invention belongs to the technical field of electric power control devices, and in particular relates to a multi-channel, multi-energy storage and transmission controller. Background technique [0002] With the rapid development of economic modernization and urban construction, energy demand growth and energy shortage are very prominent, especially the imbalance between power supply and demand is more serious. In order to alleviate the problem of power shortage, the government and society have attached great importance to the power generation of renewable energy such as solar energy, wind energy, and tidal energy. However, new types of electric energy such as solar energy and tidal energy cannot achieve stable power supply due to their greater influence by time, space, and climate. [0003] The Chinese patent number is 91225092.5, and the disclosed name is "a multifunctional controller for a solar power generation device". circuit, alarm circuit, ...
