Problems solved by technology

After the general lead-acid battery discharges the internally stored electricity, after the voltage reaches a certain value (referring to the voltage of the 24V combined battery is lower than 21.8V), continuing to discharge will cause over-discharge
Strong discharge and over-discharge can lead to lead-acid battery vulcanization, destroy the internal structure of lead-acid battery, and shorten the service life of lead-acid battery

Abstract

The invention relates to a controller using wind power conversion. The controller comprises a fan voltage identification circuit, a charging circuit, a booster circuit, a light controlled circuit, a singlechip, a light-emitting diode (LED) display panel, a fan unloading circuit, a function setting key circuit, a lamp source control circuit, a storage battery capacity detection circuit, a storage battery, a light source A and a light source B. The circuits of the controller are designed on the same circuit board and arranged in an aluminum cast metal shell so as to facilitate heat dissipation of partial elements. The controller can overcome damage of startup (onrush) to the organizational structure of the storage battery, effectively prolong the service life of the lead-acid storage battery, improve the charging efficiency and the charging quality, realize micro charge in breeze and strong charge in strong wind, and realize a cyclic process of micro charge, strong charge and floating charge aiming at the purpose of a pulse width modulation (PWM) charging mode of micro charge in breeze.

Description

technical field [0001] The invention relates to a controller utilizing wind power conversion. Background technique [0002] According to the meteorological data, the normal climate in the mainland is 2-3M wind speed accounts for 40 / 100 days of the year, the wind speed of 4-5M and above is 30 / 100 days, and the rest is no wind time. Islands, fish steaks vary. Small power refers to the combined small power supply system of wind generators below KW and batteries Dc-Ac. In recent years, the use of low-power wind turbines has become more and more extensive: offshore fishery fish raft power generation, island civil wind power generation, highway street lamp wind power generation and so on. Small-power wind turbines provide convenience for these areas where it is difficult to erect power lines or where there are hazards in erecting power lines. However, after practical application, there are still the following common shortcomings: [0003] 1. Breeze does not charge. Take a 400...
