On the Go Charging Solutions
En-Route EV Charging Infrastructure Built for the Vehicle You Haven’t Seen Yet
At a motorway service area or highway charging hub, you don’t get to plan the queue. An electric HGV, three SUVs, and a coach can arrive within minutes of each other — each expecting maximum power. Injet builds en-route charging infrastructure that handles that reality without compromise.
Key Points for On the go charging
Maximum Charging Throughput
HanYuan's dynamic power allocation ensures every kilowatt of your grid connection is working — even when vehicle mix and demand are completely unpredictable.
99%+ Station Uptime
At a remote motorway charging station, a charger down for ten days is not an inconvenience — it is a fraction of your total capacity gone during peak season. Ampax gets it back in under 4 hours.
Any Vehicle. Maximum Available Power
From a 50kW-limited city car to a 350kW-capable electric HGV — HanYuan automatically allocates the right power to each vehicle in real time, with no manual intervention
THE OPERATIONAL REALITY OF EN-ROUTE EV CHARGING
Why Most Highway Charging Stations Fail at Peak Demand — And What Operators Should Do Differently
This fundamental difference in dwell time is what separates on the go charging infrastructure from everything else — and it is why the hardware decisions matter so much more.
Most highway charging station operators discover the limitations of conventional DC fast charger deployments the hard way. During a Bank Holiday weekend, a mix of vehicles arrives simultaneously: an electric coach drawing 100kW, two SUVs each capable of accepting 150kW, and a logistics HGV that could take 350kW if the infrastructure could deliver it. With standalone, fixed-output chargers, the power available to each vehicle is locked at installation. The HGV gets the same allocation whether anyone else is charging or not. Capacity that could be generating revenue sits unused.
Injet designs en-route charging infrastructure around the one variable that motorway service area operators cannot control: what arrives next.
Dynamic power allocation
Full grid capacity accessible to any vehicle at any time
Mixed vehicle compatibility
Passenger EVs, coaches, and electric HGVs on one system
Remote fault diagnosis in 10 minutes
Critical for unmanned or low-staffed highway sites
OCPP 2.0.1 open protocol
Integrates with any CPO back-office platform
DISTRIBUTED CHARGING SYSTEM — FOR MOTORWAY AND HIGHWAY CHARGING HUBS
Every Kilowatt Working. Every Vehicle Getting What It Needs
Your peak revenue window might be two hours on a Friday afternoon. Every kilowatt counts.
Conventional chargers lock power to fixed bays. When bay three’s EV drops to a trickle charge, that unused capacity cannot reach the HGV on bay one that needs it. Your grid is paying for 1MW. You might be delivering 600kW.
HanYuan redirects power automatically — in real time, no manual override — keeping every module in its 60–80% efficiency sweet spot and holding conversion efficiency near 99% under any vehicle mix.
1,920kW
Maximum total output per HanYuan system — scalable from 480kW to match site growth
~99% efficiency
Conversion efficiency maintained under mixed vehicle load — not just at peak test conditions
No wast power
Fixed power allocations — every kilowatt dynamically available to the highest-demand vehicle.
Real-time
Power reallocation between bays — no manual override required during peak traffic
INJET Hanhui INTEGRATED DC CHARGER — ENGINEERED FOR UNMANNED AND REMOTE CHARGING SITES
Your Nearest Engineer Is Two Hours Away. Your Charger Needs to Be Back Online Today
Motorway charging stations often have no maintenance staff on site. When a conventional charger fails, you wait days for a specialist engineer. At a four-bay site, that is 25% of your capacity gone — through a Bank Holiday weekend if the timing is bad.
Hanhui was built for exactly this. With 90% less internal wiring, faults are rare. When one does occur, the system diagnoses it remotely in 10 minutes. A technician swaps the PPC unit in 15mins. The bay is back online the same day.

Is On the Go Charging the Right Fit for Your Site?
En-route and destination charging infrastructure have different priorities. Here is how to identify which solution applies to your operation.
Fleet Depot Charging — If Your Vehicles Return to Base
- Buses, HGVs, or delivery vehicles charging overnight or between shifts
- Depot operator controls the vehicle mix and schedule
- Priority is efficiency, TCO, and power cost management
- Charging infrastructure is a private operational asset
On the Go / En-Route Charging — You Are in the Right Place
- Motorway service areas and highway charging hubs
- Drivers stopping specifically to charge, not to park
- Dwell time typically 15–45 minutes
- Mixed, unpredictable vehicle types and power demands
- Uptime is critical — no alternative charging option nearby
- Revenue measured in vehicles served per hour

Frequently Asked Questions (FAQ)
Q1: What makes en-route charging infrastructure different from destination or fleet depot charging?
En-route charging serves drivers who have stopped specifically to add range — not to park or return to base. Dwell times are typically 15 to 45 minutes, vehicle types are unpredictable, and there is usually no alternative charging option nearby. This makes throughput per hour and charger uptime the two metrics that matter most, rather than overnight scheduling or fleet cost management.
Q2: How does HanYuan handle the unpredictable vehicle mix at a motorway service area?
HanYuan’s Intelligent Global Power Scheduling Algorithm coordinates every power module across every cabinet as a single unified system. When a passenger EV on one bay drops to a low draw near full charge, that released capacity automatically redirects to a high-demand vehicle — an electric HGV or coach — on another bay. No manual override is needed. Your full grid capacity is accessible to whichever vehicle needs it most, in real time.
Q3: What happens when HanHui charger develops a fault at a remote highway site?
The HanHui background monitoring system identifies the fault remotely in under 10 minutes. Because the charger’s core functions are integrated into a single Programmable Power Controller (PPC), the fix is a straightforward component swap. A competent on-site technician — no specialist high-voltage training required — can complete the replacement in 15 minutes. Total downtime including travel is typically under 4 hours, compared to up to 10 days with conventional DC charger repair.
Q4: Do I need proprietary software to manage an en-route charging site with Injet hardware?
No. Both HanYuan and HanHui are fully compatible with OCPP 1.6J and OCPP 2.0.1 open protocols, which means they integrate with any CPO back-office or network management platform you already use. Dynamic Load Management and scheduled charging are handled natively through the open protocol — no additional SaaS subscription is required
Q5: Can HanYuan scale as I expand the number of charging bays at my site?
HanYuan is designed for modular expansion. You can begin with a 480kW system and scale to 1,920kW by adding Power Cabinets without replacing the existing infrastructure. Each additional cabinet joins the same coordinated power pool, so throughput capacity grows proportionally with your site.
Q6: Is Injet hardware suitable for exposed outdoor motorway locations in the UK?
HanYuan and Ampax carry IP54 weather protection, rated for outdoor deployment in the temperature variation, humidity, and coastal conditions typical of UK motorway and highway sites. The Ampax’s integrated controller design further reduces the number of internal components exposed to environmental stress, contributing to its lower long-term fault rate.
Q7: How does Dynamic Load Management protect my site from grid demand charge penalties?
Dynamic Load Management continuously monitors the site’s total live power draw and automatically caps output to stay within your agreed grid capacity. During sudden surges — for example, when several high-demand vehicles arrive simultaneously — the system distributes available power across bays rather than allowing any single event to push total demand above the threshold that triggers utility penalty charges.
