| 发明名称 | Method for determining the internal ohmic resistance of a battery module, battery management system and motor vehicle | ||
| 摘要 | A method for determining an internal ohmic resistance of a first battery module includes measuring a first voltage intensity of the first battery module. The first battery module is connected to at least one second battery module subject to a current load after obtaining the first voltage intensity. A second voltage intensity of the first battery module is measured after the connection of the first battery module. The internal ohmic resistance is determined with reference to the first voltage intensity and the second voltage intensity. | ||
