Ask ten charge point operators what dynamic pricing means and you get three different answers. One thinks it is the power market price handed straight to the driver. One thinks it is surge pricing wearing a friendlier name. The third has a day rate and a night rate and considers the job done. All three are describing something real. None of them is describing the same thing, and the confusion costs money, because an operator who rejects the caricature also rejects the mechanism.
What is dynamic pricing at a charge point?
Dynamic pricing at an EV charging point is a tariff that moves over time according to a rule set in advance, so the price of a session reflects how much demand there is for that connector at that moment, within a floor and a ceiling the operator has fixed. It is a rule, not a number. The operator owns the rule and the boundaries. The system moves the price inside them.
Three consequences follow from that definition, and each one is a design requirement rather than a nice-to-have:
- The rule exists before the price does. If you cannot write down in one sentence why the price is what it is, you do not have dynamic pricing. You have improvisation.
- The movement is bounded. A floor protects your margin, a ceiling protects your reputation. Both are set by you, not by the model.
- The price is fixed the moment the session starts. A driver who plugs in at 18:40 pays the 18:40 price for the whole session, whatever happens afterwards.
Is dynamic pricing the same as surge pricing?
No, and the difference is structural rather than cosmetic. Surge pricing is designed to extract the most possible at the moment of scarcity. Demand-aware pricing is designed to find the point where revenue and utilisation are highest together, which is almost never the highest possible price.
| Property | Surge pricing | Demand-aware pricing |
|---|---|---|
| Goal | Maximum extraction at peak | Best combination of margin and occupancy |
| Ceiling | Often none | Fixed and published |
| Direction | Upward only | Down in the trough, up at the peak |
| Moment of truth | Price can change mid-purchase | Price locks when the session starts |
| What the customer knows | A multiplier, usually afterwards | The rule, beforehand |
Most of the public backlash against variable pricing in other industries traces back to the two middle rows: no ceiling, and a price that moved after the customer had committed. Both are avoidable in charging, and avoiding them is cheap.
Where do time-of-use blocks fit in?
If you already run a day rate and a night rate, you are running dynamic pricing. It is simply a very coarse version, with two blocks and a fixed calendar. That is worth saying out loud, because it moves the conversation away from whether the price may move and towards how finely it should move, which is the useful question.
Coarse blocks are predictable and easy to explain, and on a site with one clear demand pattern they capture a good share of what is available. They break down where the pattern is not clean. A supermarket car park behaves differently on Saturday morning than on Tuesday morning, and a two-block tariff cannot see the difference. The finer the demand pattern, the more a rule that reads actual occupancy beats a rule that reads the clock. Our own introduction to dynamic pricing for charge points works through that step in more detail.
Does European law allow a price that moves?
Yes, and this is where operators most often talk themselves out of revenue. The Alternative Fuels Infrastructure Regulation, which has applied since 13 April 2024, requires ad hoc prices at public recharging points to be reasonable, transparent and non-discriminatory. For points of 50 kW and above, the ad hoc price must be based on a price per kWh for the electricity delivered, and an occupancy fee per minute may be charged on top to discourage long occupancy. Below 50 kW, operators keep flexibility over the price structure as long as the ad hoc price is clearly and easily available.
Read that list again and notice what is not in it. The regulation governs the basis of the price, its visibility and its fairness between end users and mobility service providers. It does not require the number to be identical tomorrow. Transparency and constancy are two different properties, and only one of them is a legal obligation. A published rule with a published ceiling is more transparent than a single number that quietly gets revised twice a year.
What makes it work on a real site?
Four choices carry most of the outcome. Set a floor from your actual cost stack, including the fixed monthly cost of your grid connection, so the model can never sell below water. Set a ceiling you would be comfortable defending in a local newspaper. Lock the price at session start and say so in the app and on the screen. And change one thing at a time, so you can tell what caused the result.
There is one boundary worth stating plainly, because it is the most common way a good idea turns into a bad quarter. A tariff that follows only the energy price, spot plus a fixed margin with no demand model behind it, should never be your base or roaming tariff. It leaves your entire margin exposed to market volatility, and on a bad week that shows up directly in your result. That same tariff is genuinely attractive one layer down, as a discount for members and subscribers: easy to explain, easy to sign up for, and applied automatically once someone joins. Base tariff demand-aware, member layer energy-linked. Not the other way around.
Whatever rule you land on, verify that it actually reached the driver. A tariff update that your platform sent is not the same as a tariff a roaming partner applied, and the gap only shows up in the settlement data. That is the job tariff and revenue monitoring exists to do.
When is it not worth the effort?
When there is no demand variation to price against. A charger with a single contracted fleet behind it, or one that sits nearly empty all week, has a utilisation problem rather than a pricing problem, and a smarter tariff will not fix an empty car park. The same applies where time rather than energy is the scarce resource. The IEA counted just over one million public charging points in Europe at the end of 2024, and only about 15% of Europe's urban public chargers are rated above 22 kW. On a slow charger where a car sits for eight hours, the connector-hour is what you are really selling, and your rule should say so.
So the practical test is not whether dynamic pricing is good in general. It is whether your connectors are busy at different times in a way you can see in your own data, and whether you have the floor, the ceiling and the verification in place to move safely. If the answer is yes, the only real question left is how coarse to start. The free potential analysis puts numbers on that for your own sites, and the platform page shows how the rule, the guardrails and the monitoring fit together.
Frequently asked questions
Is dynamic pricing legal for public EV charging in the EU?
Yes. The Alternative Fuels Infrastructure Regulation, applicable since 13 April 2024, requires ad hoc prices to be reasonable, transparent and non-discriminatory, and requires pricing above 50 kW to be based on a price per kWh. It nowhere requires that amount to stay the same. What is regulated is the basis, the visibility and equal treatment, not constancy.
Does the price change while my car is charging?
Not in a properly designed system. The price locks at the moment the session starts and applies for the whole session, even if the tariff moves afterwards for drivers who plug in later. This is the single most important trust measure in the design, because uncertainty during charging is what actually drives people away.
How is this different from a normal night tariff?
A day and night tariff is dynamic pricing in a coarse form: two blocks, a fixed calendar, no response to what is actually happening. It works on sites with one clear pattern. As soon as the pattern differs by weekday, a two-block tariff cannot see the difference and you leave revenue behind in the trough and at the peak at the same time.
Do I need a lot of historical data before I start?
No. You start with the hourly patterns you already have, a floor derived from your cost stack and a ceiling you choose yourself. The model improves as sessions accumulate, but getting started mostly requires clear boundaries and the discipline to change one thing at a time.
Should my tariff follow the electricity market price?
Not as your base tariff. A tariff that only follows the spot price plus a fixed margin exposes your entire margin to market volatility. That shape belongs as a discount layer for members and subscribers, sitting on top of a base tariff that reads demand. It then stays an attractive member benefit without steering your result.
