Always looking for a better charging plan
Ready for work.
Make every charge count.
TOGL brings vehicle and charger data together with your tariffs, departure times and site limits. As conditions change, the plan can change too: charge when electricity costs less, share power across the depot, or respond to a paid grid request when there is time to move charging.
The next shift comes first. Savings and flexibility income must fit around it.
01 / Plan each vehicle
Costs change. Shifts move.
The charging plan adapts.
TOGL keeps weighing when to charge, what it costs and whether the depot can earn by pausing for a flexibility event. Each decision works around available power and the energy needed for the next shift. Try three situations for the same vehicle.

Illustrative schedules, not live telemetry. Assumes a constant 20 kW delivered to the battery and enough site power. The 120 kWh requirement includes the next-shift target and reserve. Paid flexibility depends on eligibility, an accepted baseline and event terms. This example reduces charging demand; it does not export battery energy. Real charging rates and site conditions vary.

About this illustration
This is a conceptual comparison, not a pilot result or a capacity assessment. Both states show the same six suitable existing charging bays, depot, grid connection, background site load and available charging window. Before: three trucks charge together at the connection limit, with three bays empty. After: six trucks charge in three successive pairs below that limit. Each truck has the same illustrative energy need and charging rate, so the larger fleet receives twice the energy over three times the active charging period. This is a simplified example, not a claim that scheduling doubles capacity at every depot. Real schedules depend on vehicle energy needs, departure times, charger control, connection capacity and changing site load. No solar generation, storage, export or financial return is assumed.
03 / Earn from the gridPlanned
Your charging flexibility.
A new earning opportunity.
Some grid services pay eligible depots to adjust electricity use. TOGL plans to find the charging that can move, with the energy needed for the next shift taking priority.

Look beyond the truck price.
A fair comparison includes the vehicle, finance, infrastructure, energy and maintenance. TOGL focuses on what the charging plan can change.
Grid upgrade costs are a capital expense, not an annual saving. Potential flexibility income is separate and is not needed to explore the charging case. The result depends on your depot.

FAQ
Common questions
What operators, manufacturers and energy partners ask first.
What is TOGL?
TOGL is building fleet charging and flexibility software that brings vehicle needs, charge-point data, site limits, electricity tariffs and departure plans together. Closed pilots are underway, with scope determined by the vehicles, chargers, site data and integrations involved. The aim is to lower charging costs, make better use of depot power and protect readiness, while identifying any physical shortfall early. TOGL Energy Limited is a UK company registered in Northern Ireland.
Who is TOGL for?
TOGL is for organisations that charge electric vehicles at depots, and for the vehicle and energy partners that support them. It coordinates vehicle needs, charge points, site limits, tariffs and departure plans. TOGL is not a public charging network and does not sell charging hardware.
Does TOGL require new charging hardware?
TOGL is designed to manage charging without extra TOGL hardware where suitable vehicles, chargers and supported integrations are already in place. The exact setup is checked for each depot.
How can TOGL improve the business case for electric trucks?
TOGL is developing depot charging software to use lower-cost tariff periods and make better use of existing grid connections. Flexibility market participation is Planned and could provide separate income for eligible responses. These contributions can improve electric truck total cost of ownership, but a fair comparison with diesel also includes vehicle, finance, infrastructure, energy and maintenance costs for the same work and ownership period. Value depends on the depot; TOGL does not promise universal cost parity with diesel.
What does TOGL cost?
TOGL agrees pilot scope and commercial terms directly with each operator. Terms depend on the fleet, depot, integrations and services involved, so TOGL does not publish a rate card. Contact TOGL at info@togl.co to talk through a specific depot.
Is TOGL available today?
TOGL has closed pilots underway and is recruiting more depot operators. What can be assessed depends on the vehicles, chargers, site data and integrations involved. Flexibility market participation and vehicle-to-grid are not live services.
