Claim 1:
2. The method for characterizing an energy consumption indicator of an EV according to claim 1, wherein the determining a DC energy consumption rate and an AC energy consumption rate of the EV in each of the test sub-cycles according to a result of the cyclic energy consumption test comprises:
determining a test distance of the EV in a jth test sub-cycle according to an equation dj=Σi=1Nj−1ts(vj(i)+vj(i+1))/2;
determining a DC energy consumption rate of the EV in the jth test sub-cycle according to an equation cDC,j=EDC,j/dj; and
determining an AC energy consumption rate of the EV in the jth test sub-cycle according to an equation, c
