Every idle stall is margin you already paid for

You’ve already spent the capital on hardware, civils and grid connection. The only question that matters now is how hard each stall works — and what it costs you to keep it working.

Raise utilization per stall

See utilization by site, by stall, by hour and by day — then act on it. Identify dead hours, underperforming locations and queuing hotspots, and fix pricing or capacity accordingly.

Protect uptime and driver trust

Faults surface in minutes, and many resolve remotely. A driver who finds a broken charger rarely comes back — uptime is a retention metric, not just an ops metric.

Cut the cost of every kWh

Load balancing and tariff-aware scheduling hold your peak down, so demand charges stop eating the margin on every session you sell.

Add stalls without a service upgrade

Dynamic capacity sharing lets you put more chargers behind the same connection — deferring upgrades and interconnection queues that stall expansion.

Earn beyond the session

Grid services, demand response and roaming turn your estate into more than a retail business. Revenue that doesn’t depend on a driver plugging in.

Price with intelligence

Time-of-use and demand-aware pricing that reflects what power actually costs you at that moment, protecting margin at peak and driving volume off-peak.

How we work

Your platform fee shouldn’t just be a line item. It should pay for itself.

Most CPMS vendors sell you a licence, hand you a dashboard, and invoice you every month whether your business grows or not. We think that’s backwards.

The usual model
  • Software licence billed monthly, regardless of performance
  • A dashboard — you're on your own to interpret it
  • Support that reacts when something breaks
  • Utilization is your problem
  • Fee is pure OPEX, forever
The GravOS partnership
  • We're measured on your utilization and revenue, not our uptime SLA alone
  • A named team that reviews performance with you and recommends actions
  • A rolling growth plan — where to add, upgrade, reprice or relocate
  • We actively open new revenue streams on your existing assets
  • The goal: the revenue we unlock funds the platform

What the growth partnership actually includes

01

Quarterly growth review

Utilization and margin by site, benchmarked across your estate. We bring the analysis and a prioritized action list — not just a report.

02

Expansion planning

Which sites deserve more stalls, which need a power upgrade, which should be repriced or relocated — modelled before you spend capital.

03

Pricing & tariff strategy

We help you set pricing against your real energy costs and local tariffs, so growth in volume doesn’t quietly erode margin.

04

Revenue programs

We identify and help you enrol in grid services, demand response, carbon/LCFS credit programs and roaming — then run the participation for you.

Revenue streams we work to unlock on assets you already own

Higher session volume Demand response payments Grid & ancillary services V2G energy export Carbon / LCFS credits OCPI roaming revenue Capacity deferral savings Dynamic pricing margin

Available programs and earnings vary by market, utility and asset type. We’ll map which ones your estate qualifies for before you commit to anything.

Fleets & Depots

Every vehicle ready. At the lowest possible energy cost.

A fleet depot has one non-negotiable: vehicles leave on time, fully charged. Everything else — cost, peak demand, capacity — should bend around that, automatically.

Departure-aware charging

Charging is sequenced to each vehicle’s route and departure time, not first-come-first-served. Readiness is guaranteed first; cost is optimized around it.

Energy cost optimization

Shift charging into cheap and clean windows, hold the depot under its peak threshold, and use on-site solar or storage first where you have it.

Operational effectiveness

One view of vehicles, chargers and energy. Fewer manual checks, fewer surprises at 5am, and clear accountability when something isn’t ready.

Electrify more with the same connection

Smart capacity sharing lets you add vehicles and chargers without immediately upgrading the depot’s service — the single biggest blocker to fleet electrification.

Telematics-aware

Real vehicle state of charge and schedules from your telematics provider, so decisions reflect the actual fleet, not assumptions.

Report with confidence

Cost per mile, energy per vehicle, emissions avoided — auditable numbers for finance, sustainability teams and grant reporting.

Bidirectional · V2G & V2X

A parked vehicle is a battery doing nothing

Bidirectional charging turns fleets and driveways into grid assets. GravOS manages the whole loop — when to charge, when to export, and how never to compromise the vehicle’s actual job.

Flagship use case

School buses: the best V2G asset on the road

Big batteries, fixed routes, and long predictable idle windows — mid-day, overnight, weekends, and the entire summer. No other fleet is this easy to dispatch with confidence.

  • Predictable schedules — routes are fixed, so export windows are known in advance and never risk a morning run.
  • Large usable capacity — bus packs are among the biggest mobile batteries in any fleet.
  • Idle when the grid needs help — summer peaks land exactly when buses are parked.
  • Resilience for the community — schools double as emergency shelters; V2X can keep them powered in an outage.
  • Funding-friendly — grid revenue and resilience strengthen the case for grants and district budgets.

GravOS enforces a hard readiness floor per vehicle. Route readiness always wins — export only ever happens with energy the bus doesn’t need.

Serve routesReadiness guaranteed
ExportMid-day & summer peaks
BackupPower the school in an outage
A single daily cycle: charge cheap → run the route → sell back at peak.

Commercial & municipal fleets

Delivery vans, transit, utility trucks and municipal vehicles all sit idle on predictable cycles. GravOS aggregates a depot into a single dispatchable resource — without ever missing a departure.

Utility residential programs

Run managed charging and V2X programs across thousands of homes: enrol customers, shift charging off peak, call export events when the grid is stressed, and measure it all for settlement.

V2H / V2B resilience

Vehicle-to-home and vehicle-to-building backup keeps critical loads alive during outages — an easy customer benefit that drives program enrolment.

Grid demand management

For utilities: thousands of distributed vehicle batteries become dispatchable capacity for peak shaving and local constraint relief — deferring network reinforcement.

Measurement & settlement

Auditable telemetry and event records for program measurement, verification and incentive payments — the part that usually breaks pilots.

Future-ready by standards

Built on ISO 15118 (including -20), OCPP 2.x, IEEE 2030.5 and OpenADR, so new bidirectional vehicles and chargers plug into programs you’ve already built.

Bidirectional capability depends on vehicle, charger and utility program support in your market. We’ll confirm what your specific assets and territory can do before you plan around it.

Sound familiar?

The problems we hear every week

“I find out a charger is down when a customer complains.”

Every offline hour is lost revenue and a driver who may not return.

“We send a technician for problems that turn out to be a reboot.”

Truck rolls are one of the most controllable costs in charging operations.

“Our demand charges spike because everything charges at once.”

A few peak minutes a month can set a large share of the whole bill.

“Our software vendor invoices us whether utilization goes up or not.”

Nobody on the other side of the contract is accountable for your growth.

“The grid connection limits how many chargers we can add.”

Expansion stalls waiting on capacity you may not actually need.

“We were told V2G would pay for itself. It’s still a pilot.”

Without readiness guarantees and settlement data, programs never scale.

How it works

Three steps. No rip-and-replace.

01

Connect what you own

Existing OCPP 1.6 / 2.x chargers across any brand and site, plus telematics, solar and storage where you have them.

02

Set the rules that can’t break

Departure times, readiness floors, peak ceilings, driver experience targets. GravOS optimizes everything else around them.

03

Autopilot runs it — and we grow it

The platform balances, sequences, self-heals and exports continuously. Our team reviews performance with you and plans the next move.

Works with the chargers and vehicles you already own — OCPP 1.6 & 2.x, OCPI, ISO 15118 & 15118-20, IEEE 2030.5, OpenADR. No lock-in, no forklift upgrade.
The business case

Where the money actually comes from

Six levers your finance team can model against your own bills, utilization data and local programs.

Higher utilization

The biggest lever in public charging. Better uptime, smarter pricing and capacity where demand actually is means more sessions on the same hardware.

Model it: added sessions/stall/day × margin per session × stalls

Lower demand charges

Peak charges are set by a handful of minutes each month. Capping and staggering cuts that peak without turning drivers away or delaying departures.

Model it: peak kW reduced × demand rate × 12

Fewer truck rolls

Remote diagnosis and reset removes site visits that were never necessary — the most controllable line in an O&M budget.

Model it: avoidable visits/month × fully loaded cost per visit

Deferred capital spend

Using existing electrical capacity intelligently lets you add chargers or vehicles without triggering a service upgrade or interconnection wait.

Model it: upgrade cost avoided + months of revenue pulled forward

V2G / V2X export revenue

Idle batteries sell energy and capacity back at peak. For predictable fleets like school buses, this can become a material annual line — per vehicle.

Model it: exportable kWh × vehicles × program rate

Programs & credits

Demand response, ancillary services, carbon/LCFS credits and roaming revenue — programs we help you qualify for and then run on your behalf.

Model it: enrolled kW × program rate + credits generated

Send us 12 months of bills and utilization data

We’ll model what GravOS would have saved and earned across your sites — your tariffs, your load, your programs, your numbers. No obligation, nothing to install.

Questions we get

Commercials, V2G, security and IT

What does “growth partner” mean commercially?

It means we’re accountable for outcomes, not just availability. We run a rolling growth plan with you, report against utilization and revenue, and actively enrol your assets in programs that earn. We’ll discuss commercial structures that align our incentives with your growth — talk to us about what fits your business.

Can the platform really pay for itself?

That’s the design goal, and it’s what we model with you up front — savings from demand-charge reduction and avoided truck rolls, plus revenue from higher utilization, grid programs and V2G export. Whether it fully offsets the fee depends on your estate, tariffs and local programs, which is exactly what the bill analysis is for.

Will V2G damage our vehicle batteries?

GravOS operates within the manufacturer’s permitted limits and your own policy — you set depth-of-discharge and cycle boundaries, and we stay inside them. Export only ever uses energy above the readiness floor you define.

How do you guarantee a school bus makes its route?

Route readiness is a hard constraint, not a preference. Each vehicle has a minimum state-of-charge floor tied to its schedule; the optimizer cannot trade that away for revenue. If conditions change, charging wins.

Do we have to replace our chargers or CPMS?

No. GravOS works with compliant OCPP hardware you already own, and can sit across your existing systems as the intelligence layer — or replace them, whichever fits your roadmap.

What happens if the site loses connectivity?

GravOS Edge runs locally. Load balancing, readiness rules and safety limits keep working offline, and everything reconciles with the cloud when the connection returns.

How is our data secured?

Encryption in transit and at rest, role-based access control scoped by organization and site, and audit logging of configuration and control actions.

How do we start?

Usually one site or one depot as a paid pilot, with agreed success metrics. Validate the savings and revenue on your own assets, then scale across the estate.
