【Abstract】To analyze the charging power matching of batery electric vehicles （BEVs）at normal temperature and improverelevant testing methods，this study conducted tests on the charging processof five BEV models under charging pilesof diferentspecifications inanormal-temperature experimental environment.Before the test，thevehicles were discharged to 10% State of Charge （SOC） and left to stand for more than 12 hours.Parameters including charging power and vehicle demand power in the SOC 10% ～80% （fast-charging range） and SOC 10% ～100% （full-charging range） were collected and analyzed，and the power response cofficient k was proposed to comprehensively evaluate the charging adaptabilityof themodels.

【Key words】electric vehicle；charging pile power;vehicle demand power;charging performance
