Insight from Kymco battery station pilot
👍🏻 What went well?
The feedback on the user guide was positive as it helped driver-partners to this new service by themselves.
👁 What didn’t work well/pain point?
It was challenging to discover and find battery stations from the Driver App and not help driver-partners make decisions.
Too long path: they went through 3 screens to check critical information such as address, price and available batteries.
80% of active options are redundant on the map page.
Driver-partners are confused about the price.
The team has a price strategy, which is not visible for driver-parters.

Concept
Driver-partners find battery stations by the Driver App and get batteries through battery cabinets.
Exploration
Usibility testing
We recruited 5 Viar driver-partners in Jakarta for 1-on-1 interviews and usability testing. Our testing user segment: Viar driver-partners who had used Kymco's battery cabinets and those who had not. Our goal was to test whether they could use the new concept and design to complete battery swaps.

The 4-slot battery cabinet has not screen, so I used the hardware sound playable property to create voice guide with concise, clear and warm voice. We verified it during user research and early pilot.

I delivered the end-to-end design for the mobile driver app + 2 types of battery cabinets.
The team successfully launched in Jakarta and received positive feedback from driver-partners.
Our next step would be to bring BaaS to more regions, and continue enhance the experience.
