trippler multi-destination
Planning and driving The Cape to The Cross inspired me to add EV charging contingencies to trippler. But as trippler has only historically accommodated A to B trips, I’d still had to plan the weekend’s adventure, including two overnight stops, in three distinct parts. I was therefore keen to add another new capability: routes with…

trippler contingencies
Planning to go from snow to surf in one day in an electric vehicle meant planning for resilience, to allow for things going wrong. Following a dawn-to-dusk schedule in 30-minute blocks also meant contingency planning, to know in advance what to do if things did go wrong. Read more about the adventure, and read on…

trippler at PyConAU
I was thrilled to be back for my second PyCon AU – with a wonderfully diverse and inclusive group of technologists – presenting on trippler in a talk titled An EV Trip Planner for Australia. I got a great feedback, including a suggestion to incorporate the many very (but not uniquely) Australian BIG things we…

An evergreen question: what is an MVP?
I was asked this the other day. My answer was: it depends on the context; it helps to have an example. And the contextual element is probably why this remains an evergreen question. While I have a fresh example in mind I thought I’d quickly plant a stake in the ground for reference. First, it…

trippler development notes
This is the behind-the-scenes companion post to a resilient charging planner, sharing more on the development process and how the app works, with links back to earlier work. Design philosophy I wanted to focus on the core problem of interactively exploring charging options under varying trip requirements. I wanted a tool that I would use…

A resilient charging planner
Check out the prototype of trippler, an interactive charging planner for resilient EV road trips. Based on my own EV road trip experience, trippler is as much about easily understanding charging options and contingencies, to reduce charger anxiety, as it is about coming up with a single best plan. Features Simply enter the start and…

Data complications
Solving EV charger anxiety used maths for better road trips, but skipped over using real data. Let’s fix that, or at least try to… The easy bits To get from A to B in an EV, I used Open Route Service to find a base route to a destination and and Open Charge Map to…

Solving EV charger anxiety
Many EV adventures are accessible using the charging network in Victoria, but faulty chargers still have the potential to induce charger anxiety on road trips. Planning apps–EV drivers’ constant companions–may not fully solve this when the reported status of chargers is unreliable and faults are prevalent. As a driver, I want resilient plans that already…

EV snow’d tripping
Adventures with EVs often involve big mountain climbs, which consume additional energy, impacting range. I recently had the opportunity to drive climbs from Bright to Omeo and back via Mt Hotham, in Gunaikurnai and Taungurung country, and get a sense for how EVs handle hills. I collected efficiency data for each leg of a road…

EV adventuring with resilience
Road trips are the most demanding EV scenario currently in Australia, especially to remote destinations. However, a little planning shows that they are still quite doable. Did the plans survive contact with reality? Mostly. In short, it was a pleasure to drive an EV long distances and the only inconvenience was faulty public charging infrastructure.…
