The invention provides a control circuit for automatically detecting voltage reverse batteries in an MFCs battery pack. The control circuit comprises an amplification circuit, a comparison circuit and a detection control circuit. The amplification circuit monitors output voltage of all the batteries in the MFCs battery pack in real time. The comparison circuit compares output voltage with a voltage threshold, and the batteries are accessed to a series master circuit by the detection control circuit when output voltage is greater than voltage threshold; and the batteries are disconnected from the series master circuit by the detection control circuit when output voltage is less than voltage threshold. According to the control circuit for automatically detecting the voltage reverse batteries in the MFCs battery pack, the problem that single MFC of which voltage is about to reverse lowers total voltage of the series loop in the series loop can be effectively solved so that total voltage of the series battery loop is enabled to be constantly at a relatively high voltage value.
Description
technical field [0001] The invention relates to a control circuit for automatically detecting voltage reversal batteries in MFCs battery packs. Background technique [0002] In recent years, the population has continued to grow, and it is estimated that the global population will exceed 9.4 billion in 2050. The energy crisis that comes with population growth is also gradually emerging. Over the past century, fossil fuels such as petroleum have been the main energy source for human beings. However, the consumption of fossil fuels such as petroleum has brought about many environmental pollution problems and are expected to be exhausted in the next 100 years or more. Therefore, it is particularly important to look for clean new energy and carry out energy structure reform. To this end, researchers have developed various clean energy sources such as solar energy, geothermal energy, and wind energy. Wastewater also contains energy, which exists in the form of biodegradable orga...
