Abstract
Embodiments of this application disclose a rechargeable battery monitoring system, a battery pack, and an electric vehicle. The rechargeable battery monitoring system includes multiple CMCs, a BMU, and a first bus. Each CMC is connected to the first bus and configured to monitor at least one battery module of a battery pack. The BMU is connected to the first bus and configured to communicate with at least one CMC. The rechargeable battery monitoring system further includes multiple pull-up and/or pull-down modules disposed on a communication path between two adjacent CMCs as part of the first bus. This rechargeable battery monitoring system 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.
