Embodiments of this application relate to the technical field of battery monitoring, and disclose a rechargeable battery monitoring system, a battery pack, and an electric vehicle. The rechargeable battery monitoring system includes several CMCs, a BMU (11), and a first bus (12). A rechargeable battery includes several electrically connected battery modules, and each CMC is connected to the first bus and configured to monitor at least one battery module. The BMU (11) is connected to the first bus (12) and configured to communicate with at least one CMC. The rechargeable battery monitoring system further includes several pull-up and/or pull-down modules (13). The pull-up and/or pull-down modules (13) are disposed on a communication path between two adjacent CMCs. The communication path between two adjacent CMCs includes the first bus (12) located between the two adjacent CMCs. This application further provides a battery pack and an electric vehicle, and therefore, can stabilize a level on the communication path between the two adjacent CMCs, mitigate an impact caused by external interference onto communication, and improve communication quality.
