Make depot electrification add up.
TOGL is depot flexibility software: charge for less, fit more vehicles onto the grid connection you already have, and still have every vehicle ready for its shift.
- Van and light commercial depot fleet

Modelled against unmanaged charging. Around 40% of the modelled value is charging cost savings available through smart charging today; the remainder depends on demand charge reduction (in development) and flexibility revenue (planned). Indicative ranges only, subject to TOGL modelling. Actual value depends on duty cycle, battery size, tariff structure, site constraints, charging windows, integration availability, and flexibility market access.
Depot load curve
TOGL flattens the charging peak, freeing headroom for more vehicles.
Where the value comes from. Segmented ranges are shown above, illustrative and subject to modelling.
Built by founders who have scaled EV charging software to 12,000+ charge points, designed and operated grid-scale solar, storage and EV infrastructure, and exited three founder-built ventures between them.
A national aggregates business, 40 vehicles across two depots.
The deployment is in integration: vehicles and chargers are being connected, and the sites’ capacity and shift patterns modelled against real duty cycles rather than assumed ones.
There are no measured results yet, and we will not publish any until the sites have run long enough to produce them. What this is today is a real operator, real vehicles and an agreed scope. That is more than a model and less than a case study, and we would rather say so than round it up.
The challenge
Fleet electrification is an energy control problem.
As fleets electrify, charging is no longer just an infrastructure issue. It becomes an operational, financial, and energy management problem, and the flexibility it creates is worth more than most business cases yet count.
Energy prices vary by time and location
Fleets face constantly shifting energy costs with no unified view across sites and tariffs.
Depot charging can create costly peaks
Unmanaged charging concentrates demand at shift end. TOGL models a 100-van depot peaking near 700 kW at that moment, against 250 kW for the same energy spread overnight.
Grid connections constrain how many vehicles you can run
The connection, not vehicle availability and not charger cost, is what caps how many vehicles a depot can run, and the upgrade queue is measured in years.
Vehicles move across depots, hubs, and third-party sites
Charger-centric systems lose visibility the moment a vehicle leaves a managed site.
Operations cannot be compromised by energy optimisation
Any charging strategy must protect vehicle readiness before it delivers cost savings.
How TOGL works
Connect. Optimise. Protect readiness.
Connect
Vehicle telematics, chargers, tariffs, and fleet rules flow into TOGL through supported integrations.
Optimise
TOGL is built to schedule charge windows, manage depot load, and route flexibility, in real time.
Protect readiness
Smart charging is never the reason a vehicle misses its departure. Savings and revenue sit on top of readiness, not instead of it.
The business case
Where the value comes from.
Charge for less
Shift charging into cheap overnight windows without risking departure readiness.
More vehicles per connection
Flatten the depot peak so an existing connection carries more trucks, vans, and depot vehicles, and the upgrade waits.
Earn from the grid
Make depot load available to flexibility markets. Planned, and dependent on market access and asset eligibility.
Why this is not vehicle-to-gridIllustrative value from the three sources combined: charging cost savings, connection headroom, and flexibility revenue where market access allows. Every figure on this site carries its assumptions, and every capability carries its status; the per-vehicle ranges are set out at the top of this page.

An eHGV pulls as much power as a small industrial site, and the connection decides how many you can run. TOGL makes it go further.
Explore Heavy TransportFlexibility is the missing line in the business case.
TOGL makes depot electrification add up: lower cost, more vehicles per connection, and smart charging that is never the reason a vehicle misses its departure.
TOGL is being built with a small number of depot operators. If your sites are capacity-constrained and your departure schedule is tight, that is the useful conversation.
FAQ
Common questions
What operators, manufacturers and energy partners ask first.
What is TOGL?
TOGL is depot flexibility software for operators of electric vehicle fleets. It connects vehicle data, charging context, operational readiness rules and grid capacity into a single orchestration layer, so a depot charges at lower cost, fits more vehicles onto the grid connection it already has, and still has every vehicle ready for its shift. TOGL Energy Limited is a UK company registered in Northern Ireland.
Who is TOGL for?
TOGL is built for organisations that charge vehicles at their own depot: fleet operators running vans, light commercials or electric HGVs, vehicle manufacturers who need their fleet customers to close a business case, and energy suppliers and aggregators who want access to distributed flexibility. TOGL is not a public charging network and does not sell charging hardware.
Does TOGL require new charging hardware?
No. TOGL delivers value through smart charging, depot load management and demand shifting, none of which require additional hardware. TOGL is a software layer that works with the vehicles and chargers a depot already has, subject to supported integrations.
How much can a fleet save with TOGL?
TOGL models £1,000–£3,000 per vehicle per year for a van and light commercial depot fleet, and £15,000–£34,000 per vehicle per year for an eHGV fleet. Modelled against unmanaged charging. Around 40% of the modelled value is charging cost savings available through smart charging today; the remainder depends on demand charge reduction (in development) and flexibility revenue (planned). Indicative ranges only, subject to TOGL modelling. Actual value depends on duty cycle, battery size, tariff structure, site constraints, charging windows, integration availability, and flexibility market access.
What does TOGL cost?
TOGL does not publish pricing. A depot fleet operator typically engages under a revenue share, and early access pilots carry no licence fee. Commercial terms depend on fleet size, vehicle type, integration scope and which flexibility services a site can access, so pricing is discussed directly. Contact TOGL at info@togl.co to talk through a specific depot.
Is TOGL available today?
Partly. Supported passenger vehicle integrations are live, and fleet charging intelligence, depot optimisation, grid connection intelligence and eHGV support are in active development. Bus support, flexibility market participation and vehicle-to-grid are planned rather than built. Every capability on the TOGL platform page carries one of those three statuses, and nothing is described as shipped unless it is.
