Hyundai and Kia Put Kaluza's Charging Control Inside Their Apps
Hyundai Motor Group is embedding Kaluza's smart charging controls directly into the Kia app and Hyundai's digital platforms, starting in the UK and later Australia, with vehicle-to-grid to follow.
Hyundai Motor Group has appointed energy platform Kaluza to natively integrate smart charging controls into the Kia app and Hyundai's digital platforms, launching first in the UK before expanding to Australia and other markets, with vehicle-to-grid capability planned later.
Hyundai Motor Group has handed energy software firm Kaluza the job of building smart charging controls directly into its customer-facing apps, a move that puts the carmaker rather than a third-party utility app at the centre of when its electric vehicles draw power from the grid. The controls will be native to the Kia app and to Hyundai's own digital platforms, according to electrive, and will roll out first in the United Kingdom before expanding to Australia and further markets.
The immediate benefit for drivers is simple arithmetic on their electricity bill. Smart charging means the car decides, within the driver's stated constraints, when to pull electricity — typically overnight or during whatever window a time-of-use tariff prices cheapest. Instead of the owner remembering to plug in and set a timer, the software shifts the load automatically.
Why "native" is the operative word
Plenty of EV owners already do a version of this. They use an energy supplier's app, a charger manufacturer's app, or a third-party aggregator that talks to the vehicle through an API. Each of those routes adds a handoff, and every handoff is a place where the schedule breaks: an expired token, a firmware update, a car that will not wake up when the tariff window opens.
Embedding the control in the manufacturer's own app removes those seams. The vehicle's state of charge, its thermal management, its readiness for a departure time and the charging command all sit inside one software stack that Hyundai and Kia control. For a driver, the practical difference is that smart charging stops being an add-on to be configured and starts being a default setting.
That also changes who owns the relationship. Once the carmaker holds the charging schedule, it holds the interface through which flexibility is sold — and flexibility, increasingly, is a product with a market price.
The vehicle-to-grid step is the bigger prize
Hyundai Motor Group's stated ambition goes beyond load-shifting. The partnership is meant to lead to grid stabilising and storage services through vehicle-to-grid, or V2G, in which a parked EV exports electricity back to the network rather than only importing it.
V2G matters because it converts a large, idle, already-paid-for battery fleet into dispatchable capacity. A grid operator managing an evening demand peak or an unexpected wind lull does not care whether the electrons come from a purpose-built battery park or from thousands of cars on driveways, provided the response is fast and reliable. The car owner, in principle, gets paid for it.
The obstacles are well known and they are not primarily technical. They include battery warranty terms that treat export cycles as wear, metering and settlement rules that were written for one-way domestic supply, hardware that must be bidirectional at the charger or on-board, and the question of who is liable when an aggregated fleet fails to deliver a contracted response. None of those are solved by an app integration alone. But an OEM-native control layer is a precondition for solving them at scale, because it gives one party a single, auditable channel to every vehicle in the fleet.
Britain first, for good reasons
The choice of the UK as the launch market fits the shape of the opportunity. Britain has an unusually developed retail market for time-varying electricity tariffs, a regulatory framework that has been actively courting domestic demand flexibility, and a high-voltage system that runs with growing volumes of intermittent wind generation and therefore a persistent need for short-duration balancing.
That combination gives smart charging something to optimise against. In markets with a single flat domestic tariff and no route to monetise flexibility, load-shifting saves the driver almost nothing and earns the aggregator nothing. Australia, the stated second market, has its own version of the setup: heavy rooftop solar penetration produces midday oversupply and a sharp evening ramp, which is precisely the profile that controllable charging and, later, export from vehicles can smooth.
What it means for energy retailers and rivals
In markets with a single flat domestic tariff and no route to monetise flexibility, load-shifting saves the driver almost nothing and earns the aggregator nothing.
For UK energy suppliers, an OEM-controlled charging layer is both a channel and a competitive threat. It is a channel because a supplier with a compelling EV tariff can reach customers who never open the supplier's own app. It is a threat because the traditional pitch — switch to us and use our smart charging platform — loses force when the same capability arrives pre-installed in the car.
Aggregators and flexibility service providers face the same double edge. Fleets assembled through carmakers are larger and more homogeneous than fleets assembled charger by charger, which is attractive for anyone bidding into a balancing or capacity market. But it concentrates negotiating power with the manufacturer.
Among carmakers, integration depth is becoming a point of differentiation rather than a checkbox. Several manufacturers already offer some form of scheduled charging; fewer offer a controllable, market-facing layer that a grid participant can dispatch. By contracting a specialist energy platform instead of building the stack in-house, Hyundai Motor Group is trading some control for speed — a reasonable trade when the underlying market rules differ in every country.
What to watch from here
Three things will show whether this is a feature launch or a business line. First, whether smart charging ships as an on-by-default setting rather than something buried in a settings menu, since enrolment rate is what determines the size of the controllable fleet. Second, which UK tariffs and flexibility markets the integration actually connects to, and whether drivers see a payment or only a lower bill. Third, the timeline and hardware requirements attached to V2G, including whether Hyundai and Kia extend battery warranty cover to export cycles.
The wider read is that the electric vehicle is being reclassified. It has been sold as a transport product with a battery attached. Integrations of this kind treat it as a grid asset that happens to drive — and the party that owns the software controlling it captures the value that reclassification creates.
Broader equity markets closed higher on the day the partnership was reported. The S&P 500 tracker SPY finished at $771.10, up 0.66%, while the Nasdaq 100 tracker QQQ closed at $721.11, up 1.37%, and the Dow 30 tracker DIA ended at $535.22, up 0.19%, as of 20:00 GMT on 27 August 2026.

Frequently asked questions
What exactly is Hyundai Motor Group doing with Kaluza?
Hyundai Motor Group has tasked the energy platform Kaluza with natively integrating smart charging controls into the Kia app and Hyundai's own digital platforms. Rather than routing charging schedules through a separate utility or third-party app, the control sits inside the carmaker's software, letting drivers charge automatically when electricity is cheapest.
Which markets get it first?
The partnership launches initially in the United Kingdom. Australia is named as the next market, with expansion to other countries planned after that. Britain's developed time-of-use tariff market and Australia's heavy rooftop solar penetration both create the price signals that make automated load-shifting worth something to a driver.
What is vehicle-to-grid and why does it matter here?
Vehicle-to-grid, or V2G, lets a parked electric vehicle export electricity back to the network instead of only drawing from it. Hyundai Motor Group says the integration will eventually allow drivers to participate in grid stabilising and storage. It effectively turns an idle car battery into dispatchable capacity a grid operator can call on.
How is this different from the smart charging drivers already use?
Most existing smart charging runs through an energy supplier's app, a charger maker's app, or a third-party aggregator connecting to the car over an interface. Each handoff can fail. A native integration puts the schedule, the battery data and the charging command inside one software stack the carmaker controls, which makes it more reliable and easier to make a default.
Who is affected commercially by this move?
UK energy retailers and flexibility aggregators are most exposed. An OEM-controlled charging layer can be a distribution channel for a good EV tariff, but it also weakens a supplier's pitch that customers should switch to get smart charging. It shifts negotiating power over fleet flexibility toward the vehicle manufacturer.
What are the main obstacles to V2G actually working?
They are largely commercial and regulatory rather than technical: battery warranty terms that count export cycles as wear, metering and settlement rules written for one-way household supply, the need for bidirectional charging hardware, and liability when an aggregated fleet fails to deliver a contracted grid response. A software integration is a precondition, not a solution.
