Abstract

The invention relates to the technical field of battery simulation, and discloses a battery hardware-in-the-loop simulation test method and system. In the present invention, the hardware-in-the-loop simulation test method of the battery includes the following steps: establishing a one-dimensional battery thermal model; wherein, the heat energy generated by the battery operation is evenly distributed inside the battery body; the heat energy generated by the battery operation is coupled with the battery equivalent circuit for operation ; Calculate the battery temperature based on the heat energy generated by the battery operation, atmospheric temperature and air flow. In this way, not only can it effectively reflect the real operating conditions of the battery, but also, the calculation speed is fast, the memory occupation is small, and the temperature change of the battery can be output to the battery management system in real time.

Description

technical field [0001] The invention relates to the technical field of battery simulation, in particular to a battery hardware-in-the-loop simulation test method and system. Background technique [0002] Batteries have different operating effects at different temperatures. Too low temperature will seriously affect the discharge capacity of the battery. Although high temperature can increase the electrochemical reaction speed and improve the operation of the battery, the life of the battery will increase due to the increase in temperature. Corrosion accelerates the battery aging process. The temperature change of the battery is caused by the operation of the battery and the external environment. Therefore, it is very important for the battery management system to predict the temperature profile of the battery and how the temperature change of the battery will affect the operation of the battery. [0003] At present, finite element software, such as ANSYS or COMSOL, can be u...
