机译:电池组中的散装力及其在电荷状态估计中的应用

摘要

An electrical device comprising a battery pack, a pressure sensor for measuring a change in volume of the battery pack, a voltage sensor in electrical communication with a positive terminal and a negative terminal of the battery pack, a temperature sensor positioned in the battery of the battery pack, and a battery management system do. The battery management system includes a pressure sensor, a voltage sensor, and a controller in electrical communication with the temperature sensor, wherein the controller is configured to control the battery based on the pressure read from the pressure sensor, the terminal voltage read from the voltage sensor, And to execute a program stored in the controller to determine a state of charge rate of the pack.
