摘要：
Based on the HPPC test data of 8Ah/144V lithium-ion battery pack, the PNGV model parameters are identified when operation temperature of battery pack is 20 degrees C and the model of PNGV of high-power lithium ion battery pack is build. According to actual operation characteristics of high-power battery pack, the actual output voltage and model predictive voltage are compared under the high-power battery pack different operating condition based on Arbin test bench. It's showed that the PNGV model predictive precision is not high when high-power battery pack is under steady state condition; the model predictive precision is high when high-power battery pack is under dynamic condition; the difference between model predictive voltage and actual output voltage will be bigger as the operation temperature increased.
