Description

Enhance the ride-sharing driver experience with electric vehicles through a comprehensive matching solution, optimizing everyone’s time from trip allocation to charging.

Context

I designed the Didi D1 HMI as a complete solution for electric ride-hailing. The platform seamlessly integrates intelligent range calculations, optimized batch matching, and charging station management—addressing challenges unique to full-time ride-sharing drivers using EVs.

Case Study

Case Study

Challenge


Our Research of 500 Didi-registered EV drivers shows that range anxiety is cited as the primary concern, with 90% of respondents highlighting it as a significant issue preventing them from using EVs in ride-hailing operations.


The main concern for these drivers is the system's accuracy in planning trips based on battery range. EV ride-hailing drivers often receive trip assignments that exceed their range, causing anxiety and potential service disruptions. Additionally, the availability and wait times at charging stations are critical. Full-time drivers, working 8 to 13 hours a day, lose potential earnings while waiting in queues. Efficiently locating and using charging stations is crucial for them.


Process


The design journey began with a simple sketch on paper. During discussions with product managers and other designers, we decided to redesign the dashboard architecture to improve driver efficiency and reduce task complexity.




Design Solutions


  1. Rebuild Architecture

    Redesign dashboard architecture, improving driver efficiency and reducing task complexity.



  2. Intelligent Trip Assignment

    Efficiently manages trip assignments based on battery levels and traffic prediction.



  3. Battery in the Cloud

    Optimizes battery performance, predicts accurate consumption, suggests charging schedules.



Outcome


As a result of the redesign, driver productivity improved with 1.8 more trips completed daily, safety increased with a 20% drop in accident rates, and user satisfaction rose significantly, reflected in an NPS score of 91.
