Abstract: The present disclosure relates to a power battery pack equalization method based on terrain prediction. The method includes: S1. during running of a vehicle, acquiring information of a road ahead of the vehicle; and S2. classifying the road information, setting a power prediction type based on a road information type, and switching a battery pack equalization mode correspondingly. For a low power and high energy recovery type, charging equalization is performed on a battery pack, and single batteries with low power capacity are charged through a supercapacitor; and for a road with 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. Thanks to the present disclosure, energy distribution and equalization of the entire vehicle can be more reasonable, the batteries are protected, and better economical efficiency is achieved.
