Abstract

The present invention relates to a battery reverse connection prevention circuit and a solar energy emergency convenient and rapid system and method. The circuit comprises a reverse connection prevention diode and a power amplifier which are connected with a battery; and an output end of the reverse connection prevention diode is connected with a control pin of the power amplifier, an output pin of the power amplifier is connected with the battery, the output pin of the power amplifier and an input pin of the power amplifier are earthed, and the control pin of the power amplifier is earthed through a first current-limiting resistor. Through arrangement of the reverse connection prevention diode and the power amplifier which has three end pins being earthed, the output end of the reverse connection prevention diode is connected with the control pin of the power amplifier, the output pin of the power amplifier is connected with the battery; when the battery is connected, the power amplifier is conducted, and products are electrified after the battery is connected; when the battery is reversely connected, the power amplifier with reversal of biasing/without bias is cut off, the loop of the battery is cut off, and products are not electrified so that an effect of reverse connection prevention is achieved; and moreover, the reaction is quick, and the battery reverse connection prevention circuit has an obvious advantage for reverse connection prevention of battery access and usage efficiency of products is greatly improved.

Description

technical field [0001] The invention relates to an anti-reverse connection circuit, more specifically to a battery anti-reverse connection circuit and a solar emergency emergency system and method including the anti-reverse connection circuit. Background technique [0002] Solar energy is an inexhaustible new energy source and the most abundant renewable energy source. The development of solar photovoltaic power generation technology is one of the main directions for mankind to solve the global energy crisis; solar power generation will not pollute the air, do not damage the ecology, and is a clean and green energy. The warnings of several major nuclear accidents in the world have led governments around the world to actively introduce a series of encouraging policies and regulations for the development and utilization of solar energy and other new renewable energy sources; global investment in new energy fields such as photovoltaic power generation is showing rapid developme...
