Abstract

The invention provides a battery pack simulator, which comprises a communication module, a control module and an output conversion module. The communication module receives the setting data of the battery pack and transfer the data to the control module; the control module is used for obtaining dynamic characteristics data of the battery pack according to the setting data of the battery pack, and transferring the dynamic characteristics data of the battery pack to the output conversion module; and the output conversion module is used for converting the received dynamic characteristics data of the battery pack to analog signals which represent the dynamic characteristics of the battery pack and outputting the signals. The battery pack simulator provided by the invention can stimulate all characteristic signals of the battery and the relations thereof, and can dynamically simulate a set of real batteries. When the battery pack simulator provided by the invention is used, either all the batteries in a dynamic battery pack or part of the batteries in a dynamic battery pack can be replaced, so as to check whether the calculation and control on a battery management model under different conditions is reasonable.

Description

technical field [0001] The invention relates to a battery pack simulator. Background technique [0002] Due to pressure from both environmental protection and energy sources, traditional vehicles are being gradually replaced by new vehicles such as hybrid vehicles and electric vehicles. These electric vehicles or hybrid vehicles are usually equipped with high-performance power battery packs, in which electric vehicles rely on the power battery pack to bid farewell to gasoline and achieve true zero emissions, while hybrid vehicles rely on the power battery pack to start, accelerate , deceleration, braking and other working conditions to minimize emissions, and maximize the efficiency of gasoline use. In this case, the vehicle also needs to be equipped with a battery management module. On the one hand, it is used to understand the current power and input current of the power battery pack, and coordinate other systems on the vehicle based on this information to complete variou...
