The present application relates to a power battery monitoring system and method. The system comprises a battery module, N monitoring modules and an upper monitoring platform. The N monitoring modules are connected in series with each other, and a first monitoring module is connected with the upper monitoring platform, wherein the number of sampling channels of each monitoring module is M. The power battery monitoring system can segment the battery cells; the number of the battery cells in each segment is M; the battery cells in each segment are connected with the same monitoring module; and the monitoring modules obtain the sampling data of the battery cells in this segment through the corresponding sampling channel, so as to realize the monitoring of the battery cells in this segment by the upper monitoring platform. At the same time, each monitoring module can also be connected in series to achieve the expansion of the monitoring modules. Therefore, the power battery monitoring system can select the number of the monitoring modules according to the specific number of the battery cells, is compatible with the battery modules with various configurations, and has better compatibility.
