Embodiment Construction

[0017] Such as figure 1 , figure 2 As shown, the battery protection device for solar or wind power generation system is composed of battery voltage overcharge protection circuit, battery voltage overdischarge protection circuit, voltage stabilized power supply circuit, battery, and LED lighting. VIN and GND are connected to the positive and negative DC voltage output by solar photovoltaic cells or wind generators. The time base circuits IC1 and IC2 can use 555 time base circuits. The time base circuits form R-S flip-flop bistable circuits in the battery voltage overcharge protection circuit and battery voltage overdischarge protection circuit. According to the trigger level and threshold of the two input terminals The voltage is different, the sampling circuit is divided into upper limit and lower limit sampling circuit, and the voltage difference in the hysteresis zone of 1V can be set.

[0018] The battery voltage overcharge protection circuit is composed of resistors R1,...

Abstract

The invention discloses a storage battery protecting device of a solar or wind power generation system. The storage battery protecting device is used for overcoming the defect that the traditional storage battery with higher voltage grade cannot be protected due to overcharge and voltage over-discharge. The storage battery protecting device consists of a storage battery voltage overcharge protection circuit , a storage battery voltage over-discharge protection circuit, a voltage-stabilizing power supply circuit, a storage battery and an LED illumination lamp. The charging voltage is automatically cut off when the charging voltage exceeds the highest tolerant voltage of the storage battery; and the load is automatically cut off when the discharge voltage exceeds the lowest tolerant discharge voltage. The invention is applied to the solar or wind power generation system, ensures that the storage battery works in a normal state, improves the reliability of the system and prolongs the service life of the storage battery to maximum extent.

Description

technical field [0001] The invention relates to a storage battery protection device, in particular to a storage battery protection device used in solar or wind power generation systems, belonging to the application field of electronic technology. Background technique [0002] As solar or wind power generation technology in green new energy is being developed and utilized, the storage battery that is matched with this technology is generally a maintenance-free lead storage battery, and its function is to convert the energy generated by solar panels or wind power generators when there is light and wind. The electrical energy in the battery is stored as chemical energy and released when needed. In practical applications, the two most harmful factors to the battery are: overcharging and overdischarging. The battery protection chips currently available on the market are mostly used for the protection of lithium batteries, and the voltage level is mostly concentrated at 3.6V. For...
