Title:
SOC PREDICTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/170739
Kind Code:
A1
Abstract:
Provided is an SOC prediction system (200) that predicts a battery state at a future planned waypoint of a host vehicle using energy consumption prediction parameters, the SOC prediction system being an energy consumption prediction device for enabling accurate travel planning by appropriately correcting the energy consumption prediction parameters. The SOC prediction system (200) comprises: a charge state prediction result calculation unit (300) that calculates energy consumption on the basis of the energy consumption prediction parameters, and predicts a future charge state of the battery of the host vehicle; and an SOC prediction result correction unit (310) that compares the charge state prediction result output from the charge state prediction result calculation unit (300) with the actual measurement result of the charge state of the battery measured while the host vehicle is actually traveling, calculates an error, corrects the charge state prediction result on the basis of the error, and outputs the corrected charge state prediction result as an SOC prediction result.
