The present invention relates to a power battery pack equalization method based on terrain prediction. The method includes the following steps: S1. during running of a vehicle, acquiring, by a battery management system (BMS), information of a road ahead of the vehicle from an e-horizon system; and S2. classifying the road information by the BMS, setting a corresponding power prediction type based on a road information type, and then switching a battery pack equalization mode based on the power prediction type. When the power prediction type ahead is low power and high energy recovery, charging equalization is performed on a battery pack, and single batteries with low power capacity are charged through a supercapacitor; and when the road ahead is high power and high energy consumption, discharging equalization is performed on the battery pack, and the supercapacitor is charged through single batteries with high power capacity. According to the present invention, by combining the supercapacitor with the e-horizon system for battery equalization, the energy distribution and equalization of the entire vehicle are more reasonable, thereby not only protecting the batteries, but also achieving better energy economical efficiency.
