Client Overview

Fjordlight Mobility AB

Fjordlight Mobility grew its Nordic electric vehicle fleet from a few hundred vehicles to more than 3,200 in a few years — a genuine growth success story that had completely outpaced the spreadsheet-based fleet tracking the company started with. What worked for a few hundred vehicles simply couldn't scale to thousands, and the cracks were showing everywhere. Charging station faults or downtime we...

Existing Challenges

Fleet tracking was still managed in spreadsheets, which hadn't scaled past a few hundred vehicles let alone 3,200+.
Charging station faults or downtime were often only discovered when a driver arrived and couldn't charge.
Vehicles charged whenever plugged in with no coordination, driving up costs during peak electricity demand periods.
Corporate fleet clients increasingly asked for emissions and sustainability reports Fjordlight had no automated way to produce.
Route and vehicle assignment planning didn't account for real-time battery range or charging station availability.

The Challenge

What We Were Up Against

Charging station faults or downtime were often only discovered the hard way: a driver would arrive at a station expecting to charge and find it wasn't working, with no advance warning to reroute them elsewhere. Vehicles charged whenever they happened to be plugged in, with no coordination across the fleet, which meant charging costs spiked during peak electricity demand periods that smarter scheduling could easily have avoided.

Corporate fleet clients — a growing and increasingly important part of Fjordlight's business — were asking for emissions and sustainability reports as standard due diligence, and Fjordlight had no automated way to produce them; compiling one meant manual data-pulling that didn't scale as the client roster grew. Route and vehicle assignment planning didn't account for real-time battery range or charging station availability either, occasionally assigning a route a vehicle couldn't comfortably complete without an unplanned charging stop.

Our Solution

How We Built It

The foundational piece was real-time fleet telematics — pulling live location, battery state, and vehicle health data from all 3,200+ vehicles into one platform, replacing spreadsheets that had never been designed for this scale in the first place. That same telemetry approach extended to the charging network itself, so station faults surface as an alert within minutes rather than being discovered by a stranded driver.

Smart charge scheduling was the piece with the clearest direct cost impact: rather than every vehicle charging the moment it's plugged in, the system coordinates charging across the fleet to shift load toward off-peak electricity pricing windows wherever a vehicle's schedule allows the flexibility, meaningfully reducing per-vehicle charging costs without requiring drivers to think about electricity pricing at all.

For corporate clients, we built an automated sustainability and emissions reporting module that pulls directly from real fleet telematics data — actual distance driven, actual charging sourced, not estimates — turning what used to be a manual, multi-day report-building exercise into something Fjordlight's account managers can generate on demand for any client, for any time period.

Range-aware route and vehicle assignment closed the loop: the system now factors in each vehicle's actual current battery range and nearby charging station availability before assigning it to a route, preventing the awkward situation of a vehicle being assigned a route it can't comfortably complete. We piloted the full platform on a 400-vehicle sub-fleet, deliberately including a mix of vehicle models and route types, before extending it across the full fleet and charging network.

Before vs. After

Before	After
Spreadsheet fleet tracking	Real-time telematics for 3,200+ vehicles
Charging faults discovered by stranded drivers	Proactive station health monitoring
Uncoordinated peak-hour charging	Smart scheduling shifting load off-peak
Manual sustainability reports	Automated corporate reporting portal

We grew our fleet faster than our own tools could keep up with, and it showed — drivers stranded at broken chargers, charging costs creeping up for no clear reason, corporate clients asking for sustainability numbers we couldn't easily produce. Real-time visibility across 3,200 vehicles fixed all of that at once, and the automated sustainability reports have actually become something our sales team leads with now instead of scrambling to produce after the fact.

FAQ

Common Questions

Have more questions? Book a call with our team.

How did you scale telematics tracking to thousands of vehicles?

We built the ingestion pipeline on a time-series database specifically designed for high-volume telemetry data, and validated it on a 400-vehicle pilot fleet before extending to the full 3,200+ vehicle fleet.

Does smart charging scheduling reduce driver flexibility?

Only within limits the driver's own schedule allows — the system shifts charging to off-peak windows when a vehicle has flexibility, but never delays charging a vehicle that needs to be ready sooner.

How accurate is the sustainability reporting?

Reports are generated directly from real telematics data — actual distance driven and actual energy consumed — rather than estimates, which is specifically what corporate clients wanted when they started requesting these reports.

How is driver and vehicle data protected under GDPR?

All fleet and driver data is stored on EU-based infrastructure with access controls and data handling practices designed to meet GDPR requirements from the start.
