The charger you didn't know was there: how route visibility works in Volta
Last month, a driver messaged us after a three-hour road trip to Scotland. She'd planned the route in Volta, spotted a charger 12 miles off her direct path, and saved £8 on total charging costs by detouring to it. That message sits in our Slack. It's the reason we built route-level charging visibility in the first place.
The problem we kept hearing about
When we started building Volta, we noticed something odd in driver feedback. People weren't struggling to find chargers near home or at destinations. The real friction point was the journey itself. A driver heading from London to Manchester didn't want to know about every charger in the UK. They wanted to know which chargers sat on or near their actual route, in the order they'd encounter them, with honest pricing before they arrived.
The existing approach felt backwards. You'd plan your trip in Google Maps or Apple Maps, then open a separate app to hunt for chargers along the way. Or you'd load up a charger map, spot something that looked close, and only discover once you were 200 metres away that you couldn't afford it. One commuter told us he'd driven past fourteen chargers in a single journey because he couldn't visually connect them to his route.
We realised the charger map and the journey planner had to talk to each other.
Building visibility into the route itself
The route-level feature in Volta works like this: you enter your destination, and the app plots your journey. Along that route, it shows you every charger from the 40+ networks we aggregate across the UK. But here's the detail that matters: you see the true total cost for each one before you arrive. That's the per kWh rate, plus parking fees, idle charges, and applicable taxes, all calculated together.
This sounds simple. It wasn't. To do this accurately, we had to connect to real-time data from multiple networks simultaneously, calculate actual route distances and time windows, and factor in tariff structures that vary by network, by time of day, and sometimes by how full the charger is. We spent three months chasing a bug where idle fees weren't calculating correctly for chargers that had partial pricing models. It turned out three different networks structured their idle fees differently, and we had to handle each one specifically.
The visibility piece is what changes behaviour, though. Once drivers can see a charger on their route with a price tag attached, they make different decisions. Some will charge along the way and use cheaper infrastructure. Others will skip an expensive charger and push to one further on. Some will add 20 minutes to their journey for a charger that's £3 cheaper. The app stops being a reference tool and becomes a planning tool.
The conversation with network operators
When we started integrating with charger networks, many operators were cautious about us showing their full pricing upfront. I understand why. A charger operator wants drivers to arrive with intention. But we also recognised that drivers want choice, and choice requires information.
What we've found is that transparency doesn't hurt the networks. It sorts them. The operators with fair pricing and good availability get chosen more often. The ones with confusing tariffs or poor uptime get scrutinised. That's healthy. We're not trying to undercut anyone; we're trying to give drivers the facts they need to make their own decision about whether a given charger suits their journey.
This is why every charger on your route shows you the total cost before you commit. Not just the per kWh rate, which is what most chargers advertise. The full picture. Parking. Idle fees. Everything. When you're planning a 200-mile journey, an extra £2 in idle fees across three chargers matters.
What happens when you arrive
The route planning piece is the thinking part. The arrive-to-charge check-in is the doing part. You pull up to the charger you planned to use, and the app confirms you're at the right place. No fumbling with charger IDs or network apps. You're already logged in, you already know the price, and you can start charging immediately or through your phone depending on the network's system.
For fleet managers, this matters even more. They can set route policies: chargers must be CCS, must cost under a certain amount, must have accessibility features. The driver planning their day sees those constraints built into the route before they leave the depot. The fleet manager sees the cost centre coding applied to every charge automatically. No expense spreadsheets. No guesswork about which chargers the team actually used.
We built the receipt history because drivers were telling us they needed proof of where they'd charged for tax purposes, for reimbursement, or just for their own curiosity. Export it to CSV. Hand it to your accountant. It's yours.
Why this matters for long journeys
The difference between finding a charger and planning for one becomes obvious the first time you drive more than 100 miles in an electric car. A petrol driver thinks in terms of fuel stops. An EV driver has to think in terms of charging time, cost, and whether the journey even works with their current battery. Route visibility answers all three questions before you leave.
I drove from Bristol to Edinburgh in an EV last year without the route planner built in yet. I stopped at six chargers. Using Volta's planner now, I'd stop at three, spend less time charging, and spend less money. The difference isn't just convenience. It's confidence. You know your route will work before you start.
Some of our longest discussions internally have been about what counts as 'on route'. Is a charger 5 miles off the motorway worth showing? What about 15 miles? We settled on showing any charger that doesn't add more than 10 per cent to your total journey time, but you can adjust that range yourself. A driver with a tight schedule will use a different radius than someone with time to kill.
The data that makes this work
This feature only works because we've unified 40+ charging networks into one dataset. If you had to open Shell Recharge's app, then InstaVolt's, then BP Pulse's, and cross-reference pricing, you'd never actually do it. The friction of context-switching kills the usefulness. By bringing all of them into one place, with consistent pricing information and real-time availability, route planning becomes viable.
We update network data continuously. If a charger goes offline, we know within minutes. If a network changes its pricing structure, we sync it. The route planner is only as good as the data it uses, and that data has to be accurate the moment you're deciding whether to take a detour.
That Scotland driver's £8 saving? She found a smaller independent charger on the marketplace that we'd aggregated. A venue in a village had installed a 50kW rapid and opened it to the public through our community charging feature. Volta's route planner surfaced it because it was cheaper than the major networks nearby. That's the full picture working: aggregation, transparency, and local infrastructure all in one map.
Next time you plan a long journey in an electric car, open your navigation app and then a charger app. Notice how disconnected they feel. Then ask yourself: why should planning your energy stops feel like a separate problem from planning your route?
