EV charging, made calm.
EV Station PluZ is OR's nationwide charging companion on the PTT Station network — plan a trip, start and stop charging, pay, and review history, in one app.
the problem
Drivers arrived with questions, not charging.
The same three worries surfaced on repeat — and none of them were charging problems. They were information problems: the answers existed, buried in fine print, found at the plug when it was already too late.

The same three worries, surfacing on repeat.
Not charging problems — information problems.
The answers already existed. They lived in fine print, found at the plug, too late.
Fine print became first-class UI.
The answers, one screen at a time.
A redesign inside OR's live app and brand, riding the PTT Station network — not a clean slate. What a driver needs before committing to a drive got pulled out of the fine print and onto the surface of every screen. One question at a time:
What's waiting at this station?
Station detail was redesigned to lead with the real place: a photo, the address, opening hours, power conditions and every charger with its live status — above the fold, before any terms.
Answered on the station page — facilities up front.
the redesigned station page — photo, hours, power note, chargers
How far does the network reach?
Search and the map put the whole network in one view — chargers, status and what's around them — so range anxiety is settled at home, not at the kerb.
Answered on the map — the network in one view.
the search map — every station, its status, at a glance
How does reserving a time work?
The reservation-time flow was rebuilt as a deliberate, legible step: pick the charger from the list, see its price and availability, and book — no gotchas hiding in conditions.
Answered at the charger list — reserve, with the price visible.
per-charger booking, price per kWh in plain sight
and while charging
Energy, distance, cost — then a guarded stop.
The live charging screen leads with the three numbers a driver actually thinks in — energy delivered, range gained, and what it costs so far. Stopping a charge got safeguards, so a mis-tap can't end a session early.

What the questions taught me.
What I learned
Most of the 'UX problems' here were really 'where does this information live' problems.
If I started over
Audit every fine-print condition first, ranked by how often it blocks a driver.
What I'm proud of
Turning reservation-time from a gotcha into a deliberate, legible step.
