Kaluza uses software to delay or modulate electric-vehicle charging until a driver’s preferred deadline, using energy prices, grid conditions, vehicle data and carbon-intensity signals to make flexible charging potentially cheaper and cleaner. The platform sits between energy companies, devices and customers; Google Cloud supplies much of the data, analytics and application infrastructure described in the original sponsored case study.
This is a technology case study, not an independent performance review. The central article was published on May 4, 2023, and its savings, pricing and emissions claims are vendor-reported or market-specific.
Why unmanaged EV charging creates a flexibility problem
Electric vehicles do not automatically threaten grid reliability. The challenge is timing. Many drivers plug in after returning home, concentrating new electricity demand in the same evening period when households and local networks may already be busy.
At the same time, electricity supply varies. Wholesale prices can rise during tight conditions, while renewable generation may be abundant at other times. Distribution networks can also face local constraints even when the wider grid has spare capacity.
A vehicle that needs to be ready by 7 a.m. does not necessarily need to charge immediately at maximum power. That unused timing flexibility is what managed-charging platforms try to coordinate.

What Kaluza is—and what Kaluza Flex does
Kaluza is energy software associated with OVO Energy. It provides infrastructure for energy retailers, utilities, vehicle manufacturers and smart-device businesses, including customer accounts, onboarding, billing, real-time events, APIs, data services and energy optimization.
Its current developer portal describes product areas including Retail Core, Events Streaming, Customer Self-Service Experience, Energy Optimisation and Data Mart. That is broader than the original EV case study, which focused on Kaluza Flex.
Kaluza Flex is a managed-flexibility layer. It connects electric vehicles and other flexible devices—including home batteries and storage heaters in later product material—to energy-market and grid signals. It can then optimize when those devices charge or, where supported, discharge.
In simple terms, Kaluza Flex turns a customer’s charging deadline into a controllable demand resource. The driver supplies the constraint; the platform decides how to use the available window.
How smart charging works for a driver
- The driver opens a charging application or connected energy service.
- They provide a target battery level and a time by which the vehicle should be ready.
- They plug in the vehicle.
- The platform calculates when and, where supported, at what rate charging should occur.
- The vehicle is scheduled to meet the requested deadline, subject to the vehicle, charger, tariff, connectivity and available charging window.
- The app can present charging status and may show billing, carbon or battery-related information.
That differs from ordinary timed charging. A basic timer might start at midnight every night. Smart charging can re-evaluate the schedule as prices, renewable availability, grid signals, forecasts or the driver’s requirements change.
The practical promise is not that every vehicle always charges at the single “greenest” moment. It is closer to: the system will optimize charging within the customer’s chosen window while respecting technical and market constraints. The public case study does not disclose the exact weighting between price, carbon intensity, grid support, battery protection and other objectives.

For a full list of compatible models, check out the Full Compatibility List on our product page.
- Indication Displays - LED display that can tell you the status as well as indicate errors while charging your electric vehicle.
What data does the platform use?
The case study identifies several inputs:
- Vehicle battery state and charging information.
- Vehicle or chargepoint status.
- Customer preferences and required departure times.
- Energy prices and price forecasts.
- Energy-supplier data.
- Grid-operator signals.
- Carbon-intensity information.
The optimization engine uses these inputs to create a charging schedule. “Cheapest” and “greenest” are not automatically the same: low-price electricity can have a different carbon profile, and a schedule that reduces emissions may not minimize cost. Carbon accounting also depends on whether the system uses average or marginal grid intensity, how forecasts are updated and whether charging losses are included.

Google Cloud is the enabling infrastructure, not the energy retailer or the device controller in isolation. Kaluza still needs integrations with vehicles, chargepoints, utilities, tariffs, energy markets and grid systems. Device connectivity, command authentication, fallback behavior and local regulatory requirements remain essential.

Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteCharge Anytime: useful example, not a current universal price
The original case study described OVO’s Charge Anytime tariff as offering EV charging at 10 pence per kWh, approximately one-third of the household electricity rate at that time. A later Kaluza announcement cited a UK rate of 7 pence per kWh and approximately £190 per year for driving.
Those figures are historical, UK-specific and dependent on tariff terms, eligibility, vehicle use and publication date. They should not be treated as August 2026 prices or as a guarantee for every OVO customer. Anyone considering the consumer tariff should verify the current OVO terms, supported vehicles and supported chargepoints.

V1G, V2G and V2X: what is the difference?
V1G, or unidirectional smart charging, controls when a vehicle draws electricity. The battery does not send energy back to the grid.
V2G, or vehicle-to-grid, allows a compatible vehicle to export stored electricity to the grid.
Free tools Windows power users keep installed
One-click scans. No signup required.
V2X is the broader category. The destination might be the grid, a home, a building or another load.
Kaluza describes V2G activity involving UK programs and says the same broad cloud architecture supports bidirectional services. The Google Cloud account reports average V2G savings of £450 per year, with some participants saving up to £800 per year. These are company-reported trial results; the cited case study does not provide the sample size or full methodology, so they should not be generalized.
V2G participation requires all of the following:
- A vehicle capable of bidirectional charging.
- A bidirectional charger and compatible communications.
- A supporting tariff, utility program or market.
- Local permission to export energy and, where required, interconnection approval.
- Clear rules for battery warranties, degradation and minimum state of charge.
Export revenue is not pure profit. The calculation should include round-trip losses, battery wear, possible warranty limitations, charger costs and the driver’s need to retain energy for an unexpected trip. The system also needs a reserve so it does not optimize market participation at the expense of the driver’s mobility.
Current partner and geographic context

Later Kaluza announcements and newsroom material discuss relationships or initiatives involving BMW Group, ENGIE, PG&E, Wallbox, Nissan, Stellantis, Sonnen, Glen Dimplex and Bosch. In particular:
- Kaluza announced participation in a PG&E dynamic-pricing pilot, where eligible drivers use an integrated chargepoint and application to access hourly pricing.
- Kaluza announced a Wallbox partnership for V1G and V2G programs in Northern and Central California.
- The Kaluza newsroom records later announcements, including 2025 initiatives.
A partnership announcement does not prove general commercial availability. Buyers must distinguish among technical capability, a pilot, an announced partnership, a commercial launch and eligibility for a specific vehicle, charger, tariff and geography.
What the original case study does not establish
The sponsored material does not independently establish:
- Forecast accuracy, uptime or charging-completion rates.
- Customer satisfaction, retention or participation levels.
- Total cost of ownership for an enterprise deployment.
- A universal reduction in emissions or grid peaks.
- Battery-degradation outcomes from V2G.
- Complete privacy, cybersecurity or data-retention practices.
- Current enterprise pricing, service-level terms or the full integration matrix.
Those omissions matter because the difficult part of managed charging is not simply running containers or storing data. It is integrating devices, settling energy transactions, forecasting uncertain conditions, handling failures and creating incentives that customers will accept.

The car is plugged in too late
If the charging window is too short, reaching the requested battery level may be physically impossible. A trustworthy product should show that limitation clearly rather than silently promising a full charge.
The driver needs the car immediately
Smart charging depends on a reliable ready-by time. A manual override may require more expensive or less carbon-efficient charging, and the customer should understand that trade-off.
Forecasts change
Prices, weather, renewable output and grid constraints can change after a schedule is created. The platform should re-optimize when appropriate and explain why a schedule changed.

Connectivity fails
Buyers should ask whether charging falls back to a safe default if the vehicle stops reporting, the charger loses internet access, an API times out, a utility signal is delayed or a cloud region becomes unavailable.
Privacy and cybersecurity
Managed charging can involve location, driving patterns, account information, billing data and device identifiers. Procurement should cover consent, data minimization, encryption, access controls, retention, breach response and third-party sharing.
Due-diligence checklist for a buyer
- Market fit: Which countries, utilities, tariffs and regulatory regimes are supported?
- Integrations: Which vehicle brands, chargers, smart meters and market systems are live—not merely planned?
- Control: Does the platform support V1G, V2G, V2X and other flexible devices?
- Optimization: Can it prioritize price, carbon, local network constraints, battery health and hard departure deadlines?
- Reliability: What is the fallback when cloud, connectivity, telemetry or utility signals fail?
- Customer control: Is there a manual override, minimum state-of-charge reserve and clear explanation of schedule decisions?
- Settlement: How are savings, flexibility payments, imbalance exposure and market performance calculated?
- Commercials: What are the license, integration, support, data and implementation costs?
- Measurement: What baseline is used for price, carbon and peak-demand claims?
- V2G: Who carries responsibility for battery degradation, export compliance and warranty conditions?
- Data governance: Where is data stored, who can access it and how long is it retained?
Public materials do not disclose Kaluza’s full enterprise pricing, implementation fees, service-level commitments or complete integration list. A buyer should request those details directly and compare them with the cost and operational burden of building an equivalent system.
Bottom line
Kaluza demonstrates how managed EV charging can turn vehicles from passive electricity loads into flexible energy assets. Its software combines customer deadlines with price, grid, vehicle and carbon data, while Google Cloud provides the reported data, analytics, container, database and dashboard infrastructure.
The idea is technically credible, but its value is conditional. Savings and emissions reductions depend on market design, device compatibility, customer participation, forecast quality, local constraints and transparent measurement. For an energy retailer, utility, automaker or flexibility provider, Kaluza is best evaluated as an enterprise energy platform—not as a universal consumer charging product and not as a substitute for the integrations, governance and energy-market expertise required to operate one.
