【Abstract】The power and endurance performance of AOO micro electric vehicle sodium-ion batery and lithium-ion batery under low temperature conditions arecomparedandanalyzed bycapacity calibrationand HybridPulse Power Characteristics （HPPC）test.Theresults ofthesecond-orderRCequivalentcircuit modeland vehicle simulation indicate the following： In terms of power performance，the maximum speed of the sodium-ion battery model is 3.4km/h higher than that of the lithium-ion batery model （O.6～0.8 in the state of charge） under low temperature （-5∘C ）conditions.In terms of driving range，lithium-ion batery models have significant advantages under high temperature （ 35∘C conditions（ 45km longer driving range）， but sodium-ion battery models have a driving range that is 37km longer than lithium-ion battery models under low temperature （-5∘C） conditions，and their capacity attenuation and internal resistance changes are smoother.
