A battery information collection system of a bus micro-power consumption group comprises multiple batteries (1) connected in series, each of the battery (1) is connected to a separate sampling plate (2) for sampling information from the battery, each of the sampling plate (2) is mounted on a corresponding battery (1) nearby and connected to a communication bus (4) arranged nearby, and the communication bus (4) is connected to a secondary control plate (3) used for data aggregation. By providing one sampling plate (2) proximal to each of the batteries (1), proximally connecting each of the sampling plates (2) to the communication bus (4), then extracting a line from the communication bus (4) to connect to the secondary control plate (3), a wiring in the box is greatly simplified and a sampling error caused by a long line, an electromagnetic interference, and the interference of various unpredictable problems is effectively reduced. Each of the sampling plate (2) is relatively independent, such that the present invention is suitable for any grouping schemes of the battery, thus eliminating the need for redesigning the battery information collection system for different grouping schemes, and guaranteeing portability and extensibility of the solution. |
