Abstract

The invention relates to the technical field of battery simulation and discloses a battery hardware-in-loop simulation testing method and system. The method includes: building a one-dimensional battery heat model, wherein heat energy generated during battery operation is evenly distributed in a battery body; coupling the heat energy generated during battery operation with a battery equivalent circuit; calculating according to the heat energy generated during battery operation, atmosphere temperature and air flow to obtain battery temperature. The method has the advantages actual battery operation conditions can be reflected effectively, fast calculation and low internal memory occupation are achieved, and battery temperature change can be output to a battery management system in real time.

Description

Technical field [0001] The present invention relates to the field of battery simulation technology, in particular to a battery hardware-in-the-loop simulation test method and system. Background technique [0002] The battery has different operating effects at different temperatures. Too low temperature will seriously affect the battery's discharge capacity. Although high temperature can increase the electrochemical reaction speed and improve the battery operation, the battery life will increase due to the increase in temperature. Corrosion accelerates the battery aging process. The temperature change of the battery is caused by the operating condition of the battery and the external environment. Therefore, for the battery management system, it is very important to design the thermal management system to predict the battery temperature profile and how the temperature change of the battery affects the operation of the battery. [0003] At present, you can use finite element softwar...
