The invention discloses a current power consumption estimation method and system of a pure electric vehicle and a road section power consumption estimation method. The method for estimating the current power consumption of the pure electric vehicle comprises the following steps: determining a plurality of target slope values and determining a plurality of target environment temperature values in an environment temperature range; traversing to obtain a V-P-T0-EC1 relation table of the target pure electric vehicle; traversing to obtain a V-P0-T-EC2 relation table of the target pure electric vehicle; the current running speed, the road gradient, the environment temperature and the information whether an air conditioner is turned on or not of the target pure electric vehicle are obtained; and according to the current running speed of the target pure electric vehicle, the road gradient, the environment temperature, the information whether the air conditioner is turned on or not, the V-P-T0-EC1 relation table and the V-P0-T-EC2 relation table, the current power consumption estimated value of the target pure electric vehicle is obtained. The vehicle speed, slope, temperature and power consumption relation table is obtained by traversing different vehicle speeds, road slopes and environment temperatures, the power consumption of the current vehicle can be rapidly obtained, the relation between various different influence factors and the power consumption is considered in an aggregated mode, and the precision of the power consumption estimation result is high.
