Abstract:
By employing the energy-flow testing technique, this study probes into the environmental adaptability of electric vehicles based on the worldwide harmonized light duty driving test cycle. The following conclusions were reached. Compared with the conditions under normal temperatures, the AC system and the PTC consume 18%-20% energy of the battery, the mileage reduces by 32% to 48%, and the energy consumption per 100 km increases by 49% to 81%. From the perspective of single cycles, the total mileage divides into three stages, among which the first stage shows the largest cycle difference. A correction factor is proposed based on the energy equilibrium relations, and the correction factor for the first stage under normal, high and low temperatures are 1.022, 1.050 and 1.184 respectively. Meanwhile, the discharging internal resistance of the battery under low temperatures differs significant from those under high or normal temperatures, showing an increase by 2%-5%, while the charging internal resistance shows no significant differences.
