Abstract

The invention belongs to the technical field of battery management systems, and discloses a single voltage acquisition circuit, method and device. The present invention constitutes a single voltage acquisition circuit by setting a voltage sampling circuit, a signal isolation circuit and a microcontroller; the voltage sampling circuit is connected to the signal isolation circuit, and the signal isolation circuit is connected to the microcontroller; wherein, the voltage sampling circuit is used to obtain battery The sampling voltage of the single cells in the group, the battery pack includes several single cells connected in series; the signal isolation circuit is used to convert the sampling voltage into a voltage signal without loss, and output the voltage signal to the microcontroller; the microcontroller, It is used to receive the voltage signal and perform analog-to-digital conversion to obtain the voltage signal of the corresponding single battery. Through the above method, the single voltage collection of the metal-air battery is realized, which solves the technical problem that the existing technology cannot meet the voltage collection requirements of the working voltage platform of the metal-air battery.

Description

Technical field [0001] The present invention relates to the technical field of battery management systems, and more particularly to a monomer voltage acquisition circuit, a method, and a device. Background technique [0002] In recent years, with the strong support of national policies, and the continuous advancement of science and technology, electric vehicles have a long development. In 2017, the sales of electric vehicles in 2017 reached 770,000 vehicles, and the total number of more than 1.6 million vehicles, accounting for the global total. Half, developing electric vehicles to optimize energy consumption structure, can reduce the air pollution of urban traffic, but the pain points for electric vehicles further develop, and restrict consumers to purchase willingness for electric vehicles or the battery life of electric vehicles and electric vehicles. The problem. The metal air battery exceeding a large energy density of the lithium battery is successful, but the working volt...
