Abstract
An alternating-hibernation battery management and control method for a power structure of a large electric vehicle is provided. The power structure includes a vehicular computer with a sorting controller, plural configuration-variable series-type battery boxes in parallel connection and a driving device. Each configuration-variable series-type battery box includes plural battery modules in series connection. The method includes the following steps. Firstly, the vehicular computer calculates a required number of battery modules and a required number of configuration-variable series-type battery boxes. Then, the vehicular computer performs a temperature protection process. Then, the sorting controller calculates module scores of all battery modules, and generates a battery module sorting result. Then, the sorting controller enables the required number of battery modules according to the required number of battery modules and the battery module sorting result. Then, the sorting controller calculates a battery box score and generates a battery box sorting result. Afterwards, the sorting controller controls at least one configuration-variable series-type battery box in the last rank of the battery box sorting result to be in a hibernation mode.
