Abstract

The invention, which belongs to the technical field of battery management systems, discloses a single voltage acquisition circuit, method and device. According to the invention, a voltage sampling circuit, a signal isolation circuit and a microcontroller are arranged to form a single voltage acquisition circuit. The voltage sampling circuit is connected with the signal isolation circuit; and the signal isolation circuit is connected with the microcontroller. The voltage sampling circuit is used for acquiring a sampling voltage of each single battery in a battery pack including a plurality of single batteries connected in series. The signal isolation circuit is used for converting the sampling voltages into voltage signals through lossless processing and outputting the voltage signals to the microcontroller. The microcontroller is used for receiving the voltage signals and performing analog-to-digital conversion to obtain the voltage signals of the corresponding single batteries. Through the mode, the single voltage collection of the metal-air battery is realized; and a technical problem that the voltage acquisition requirement of the working voltage platform of the metal-air battery cannot be met in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of battery management systems, in particular to a single voltage acquisition circuit, method and 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 made great progress. In 2017, the sales volume of electric vehicles in the country reached 770,000, and the number of vehicles in stock exceeded 1.6 million, accounting for the global total. The development of electric vehicles can optimize the energy consumption structure and reduce the air pollution of urban traffic, but the pain point of the further development of electric vehicles and the restriction of consumers' willingness to purchase electric vehicles are the mileage of electric vehicles and the long charging time of electric vehicles The problem. Metal-air batteries, which exceed the energy density of lithium batteries by sev...
