Hybrid vehicle-to-grid algorithms fail to beat simpler alternatives, study finds.

Hybrid vehicle-to-grid algorithms fail to beat simpler alternatives, study finds. Peer-reviewed study finds hybrid V2G scheduling algorithms offer no advantage over simpler APSO approach, questioning vendor claims in smart charging market. September 24, 2026 V2G is currently being explored across the globe, including Australia, with the likes of Ausgrid trialing the technology. A peer-reviewed study testing seven optimisation algorithms for scheduling EV charging and discharging in vehicle-to-grid (V2G) systems has found that combining two algorithms into a "hybrid" does not automatically produce better results than using the stronger of the two on its own. The study, published in the journal Processes, was conducted by researchers at the University of Engineering & Technology Lahore, the University of Management and Technology Lahore, the University of Johannesburg and the University of Botswana. The researchers tested the algorithms against a simulated smart parking facility where EVs arrive and depart across a scheduling window, each with its own battery capacity and driver-preferred charge level, under a time-of-use electricity pricing scheme with peak, mid-peak and off-peak periods. Particle Swarm Optimization (PSO) and the Whale Optimization Algorithm (WOA) are both metaheuristic algorithms, meaning they search for a near-optimal solution to a complex problem by mimicking a natural process rather than solving it exactly. PSO models a swarm of candidate solutions that move through the search space influenced by their own best-known position and the swarm's collective best position, while WOA is modelled on the bubble-net hunting behaviour of humpback whales, alternating between encircling and spiralling movements to close in on a solution. Adaptive Particle Swarm Optimization (APSO) is a refined version of PSO that continuously adjusts its own internal search behaviour, tightening or loosening its search pattern in response to how clustered or spread out its candidate solutions are at each step, rather than following a fixed search pattern throughout. APSO was the best-performing algorithm in the study, improving on standard PSO by 8% and on a PSO-WOA hybrid, which combines elements of both algorithms in an attempt to capture the strengths of each, by 9.7%, while also producing a measurably flatter peak load demand profile across the simulated charging facility. The researchers found the PSO-WOA hybrid performed no better than plain PSO once tested statistically, and a separately enhanced version of WOA could not be shown to outperform the standard WOA either. Of the seven algorithms tested, only APSO's advantage held up consistently after applying the full battery of statistical tests across the 100 simulation trials for each algorithm. The researchers ran parametric tests, including t-tests and ANOVA, and non-parametric tests, including Mann-Whitney U, Wilcoxon Signed-Rank, and Friedman tests, and post-hoc corrections, including Holm's Step-Down, Bonferroni-Dunn, and Nemenyi analyses, specifically to distinguish genuine performance improvements from results that could plausibly have occurred by chance. The paper argues this level of validation is uncommon in existing V2G scheduling literature, noting that most prior studies report performance improvements without statistical testing to confirm that those improvements are real. The researchers conclude that, for this class of scheduling problem, the effective mechanism behind APSO's advantage is its adaptive control of internal search parameters, which adjust based on the distribution of the algorithm's search population at each iteration, rather than the act of hybridising two algorithms. That distinction is directly relevant to vendors marketing "hybrid" or multi-algorithm optimisation as inherently superior to a single, well-tuned approach. Vendor performance claims contrast with independently validated trials. The findings arrive as V2G and smart charging platforms increasingly lean on algorithmic and AI-branded capability as a point of commercial differentiation. As reported by EV Infrastructure News, Geely recently launched an AI-powered fast-charging system, Xingrui PowerMind, built with Chinese AI company StepFun, which the company says predicts battery temperature up to 30 seconds ahead to dynamically adjust charging power. Geely claims a 20% improvement in battery lifecycle when the system is combined with its pulse-restoration technology. As with much of the smart charging software market, those figures come from the manufacturer's own testing rather than independent statistical validation of the kind applied in the Processes study. The commercial stakes for getting scheduling right are rising as more automakers commit to V2G on a global scale. Hyundai Motor Group and energy intelligence platform Kaluza launched a partnership in August 2026 to embed smart charging into the Kia and Hyundai apps, starting in the UK and Australia, with V2G services planned to follow from 2027. Kaluza CEO Stephen Fitzpatrick described the partnership as laying the technical foundation for how EVs integrate with the energy system more broadly. The real-world value of that claim will depend on how well the underlying scheduling software performs against driver charging preferences and grid price signals under live conditions, precisely the kind of question the Processes paper argues needs independent statistical testing rather than vendor-reported figures alone. By contrast, one of the clearer examples of rigorously validated smart charging in the market to date comes not from a vendor claim but from a randomised controlled trial. The Centre for Net Zero, an Octopus Energy-founded research institute, ran a 12-month RCT across more than 13,000 UK households and found that AI-managed charging cut peak household electricity use by 42% and reduced annual bills by £650 (US$887), with more than half of participating households never manually overriding the automated system. That trial's design, a control group tested against four treatment groups and tracked over a full year using high-frequency smart meter data, offers a template for the kind of evidence base the Processes researchers argue is largely missing from the algorithmic V2G literature more broadly. Not every claim in the smart charging market has been put through this kind of scrutiny. The Processes study is itself not without limitations. Battery degradation costs and charging-efficiency losses are explicitly excluded from its model, and the entire parking facility is treated as a single connection point to the grid rather than modelling feeder- or transformer-level constraints. The researchers acknowledge that incorporating these factors would likely yield more conservative cost estimates and flag the work as a direction for future model refinement rather than a claim that the study reflects a full commercial deployment. In that sense, the paper's core contribution is methodological rather than a ready-made blueprint for production scheduling software. It demonstrates how to rigorously test competing algorithms, more than it proves that any single algorithm is ready to be deployed at scale.

Hyundai reveals battery cells that cut charging time by 40%

September 1, 2026 Hyundai reveals battery cells that cut charging time by 40%. The announcement forms part of a broader electrification strategy that Hyundai laid out at the event.Image: Hyundai. Hyundai Motor Company has revealed in-house developed battery cells that deliver more than double the output of the high-nickel cells it previously used, while cutting charging time by 40%, as part of its 2026 CEO Investor Day held in Seoul, South Korea. The announcement forms part of a broader electrification strategy that Hyundai laid out at the event, alongside targets of 5.55 million global vehicle sales by 2030 and an operating profit margin above 9%. The new cells will first be applied to the company's Extended Range Electric Vehicle (EREV) models, which are expected to arrive in the first half of 2027. Hyundai said these models will use less than half the battery capacity of a comparable full-electric vehicle while delivering equivalent battery performance and EV driving dynamics. Separately, EV models launching in 2027 will use mid-nickel NCM cells, which Hyundai said reduce battery cost by around 30% while maintaining performance under real-world driving conditions. Alongside the new cell chemistry, Hyundai detailed a cloud-based battery management system (BMS) upgrade intended to extend battery life by an average of 20% by 2028, and a new safety technology called Thermal Runaway Protection (TRP), which blocks the transfer of heat between adjacent cells in the event of a battery fire using a dissipation-focused battery system and a barrier structure between cells. Hyundai said existing industry approaches could only delay heat transfer for a period, whereas TRP is designed to block it at the source regardless of battery type. The company said it has verified TRP through more than 200 repeated tests on prismatic and pouch NCM batteries, with the technology debuting on the Genesis GV90. Faster charging has been a consistent theme across Hyundai's recent technology announcements beyond the new cells themselves. In June, Hyundai Motor Company Australia (HMCA) completed the country's first vehicle-to-grid (V2G) discharge using the ISO 15118-20 communication standard, pairing an IONIQ 9 with StarCharge's Halo bidirectional DC charger. HMCA chief executive Don Romano said at the time that getting the standard right was essential because V2G would only scale in Australia if consumers, energy providers and governments could trust the technology, positioning that trial as groundwork for the kind of bidirectional, software-managed charging Hyundai is now building into its wider vehicle lineup. That direction extends to smart charging more broadly. In August, Hyundai Motor Group partnered with energy intelligence platform Kaluza to co-develop smart charging capabilities integrated into the myHyundai and Kia apps, with the UK the first market for deployment, followed by Australia. Kaluza chief executive Stephen Fitzpatrick described the partnership as laying the foundation for V2G services planned from 2027, designed to let vehicles charge automatically when renewable energy generation is high and prices are low. The 40% charging-speed improvement Hyundai has claimed for its new cells stands against a backdrop of growing industry attention to how well batteries actually perform once vehicles reach the used market. Independent testing by UK diagnostics firm Generational recently found that around 1 in 85 used EVs carries a hidden cell-level imbalance not visible through standard State of Health (SoH) reporting, a fault that can affect range, charging behaviour and long-term value without triggering any dashboard warning. Hyundai's cloud-based BMS upgrade, designed to detect early signs of cell abnormality in real time, addresses a risk category similar to the one Generational's testing identified, though on newer vehicles rather than the used fleet covered by Generational's dataset. Hyundai's own account of its battery strategy traces back through its independently developed hybrid systems and its global Electric-Global Modular Platform (E-GMP), which underpins the IONIQ 9 used in the Australian V2G trial.

Hyundai partners with Kaluza to bring smart EV charging to Kia and Hyundai apps.

Hyundai partners with Kaluza to bring smart EV charging to Kia and Hyundai apps. Hyundai Motor Group is partnering with energy intelligence company Kaluza to develop smart charging technology for its electric vehicles, creating a more seamless connection between EVs and the energy grid. The global technology partnership is scheduled to begin rolling out in August 2026, initially covering Kia and Hyundai EVs in the UK before expanding to Australia. The technology will be integrated directly into the Kia App and myHyundai App, allowing drivers to manage smart charging without relying on a separate energy app. The partnership is designed to make EV charging more convenient while helping drivers reduce both charging costs and carbon emissions. Instead of manually choosing when an EV should charge, the integrated system can automatically schedule charging for periods when electricity is cheaper and cleaner. Drivers can set when their vehicle needs to be ready, while the software handles the timing in the background. The UK rollout will initially include OVO as the first energy retailer to provide smart charging through the Kia App. Kia owners who use OVO will therefore be able to manage their vehicle and charging in one place. Drivers currently using the OVO Charge app are expected to transition to the Kia App in early autumn, with Hyundai drivers expected to gain access shortly afterward. Discover more Rent Luxury Handbags Hyundai Motor Group says the partnership goes beyond a conventional app integration. The companies are working together on the underlying technology that will allow EVs to interact more intelligently with energy networks. Woong Tae Hwang, Vice President and Head of EV Energy Strategy Group at Hyundai Motor Group, said the company chose Kaluza because of its expertise in energy intelligence and its ability to work on advanced EV-energy integration. The technology could eventually allow EVs to become an active part of the electricity system rather than simply consuming electricity. Kaluza's platform is being embedded directly into the automakers' digital ecosystems, giving drivers control over charging from their smartphones while allowing the system to respond to electricity prices, renewable energy availability and grid conditions. One of the most important developments enabled by the partnership is vehicle-to-grid (V2G) technology. Hyundai Motor Group and Kaluza are laying the groundwork for V2G services expected to begin in 2027. Unlike conventional smart charging, V2G allows compatible EVs to send stored electricity back to the grid when needed. Discover more Renault 5 E-Tech electric Compare Electric Cars Renault 5 E-Tech Electric That could create another potential source of value for EV owners. Vehicles could charge when electricity is abundant and inexpensive, then potentially supply energy back to the grid during periods of higher demand. The technology could also help make better use of renewable energy. When solar or wind generation is high, EVs can provide a flexible source of electricity demand by charging at times when cleaner energy is more readily available. For drivers, the biggest advantage is convenience. Rather than monitoring electricity prices or renewable-energy production, the smart charging platform can automate those decisions. A driver can specify when the car needs to be ready, while the system determines an appropriate charging schedule based on available energy and cost. The approach could become increasingly important as EV adoption grows. Millions of electric vehicles connected to the grid represent a significant source of flexible energy demand, particularly when charging can be coordinated automatically. OVO's Director of EV, Alex Thwaites, said the goal is for drivers to charge at cheaper and greener times without having to actively manage the process. The Kaluza partnership represents a broader shift in how automakers are approaching EV ownership. Charging is increasingly becoming part of the vehicle's connected digital ecosystem rather than a separate service handled entirely by charging networks or energy providers. By integrating smart charging directly into the Kia and Hyundai apps, Hyundai Motor Group can give EV owners a single interface for vehicle and energy-related functions. The initial rollout in the UK and Australia will provide a foundation for expanding the technology to additional markets and services. The planned introduction of V2G capabilities from 2027 could take that integration further, turning compatible EVs into flexible energy assets. As electric vehicle adoption continues to increase, partnerships between automakers, energy companies and technology providers are likely to play a growing role in determining how EVs interact with the electricity grid. For Kia and Hyundai drivers, the first step will be simpler: letting the car automatically charge at the right time, rather than making the driver decide when to plug in.

Hyundai Group integrates smart charging control from Kaluza.

Hyundai Group integrates smart charging control from Kaluza. The Hyundai Motor Group has tasked energy platform Kaluza with natively integrating smart charging controls into the Kia app and Hyundai's digital platforms. This will allow EV drivers to charge when power is cheapest and eventually participate in grid stabilising and storage with vehicle-to-grid (V2G) capabilities. The partnership will initially launch in the UK and subsequently expand to Australia and other countries. By Cora Werwitzke 27.08.2026 - 13:30 The Hyundai Motor Group volume brands, Hyundai and Kia, are offering smart charging options in collaboration with the British company Kaluza. The grid-supportive smart charging initiative will be launched internationally, starting in the UK. The offer introduces the integration of smart charging control into the group's digital ecosystem, primarily within the Kia App and the myHyundai App. These new features will simplify smart charging and, in the future, enable vehicle-to-grid (V2G) applications planned for Hyundai and Kia from 2027 onwards. The Hyundai Motor Group announced in July this year that it would launch a new umbrella offering called AllDayEnergy, bundling all services related to smart charging, Vehicle-to-Grid (V2G), and Vehicle-to-Home (V2H). These intelligent energy services integrate electric vehicles into domestic power grids and public distribution networks. Initially, smart charging will be enabled to allow drivers to charge when convenient and when electricity is cheapest, while full bidirectional applications will follow in later phases, enabling the EV battery to serve as a temporary storage solution for the public grid (V2G) and home networks (V2H). The Kaluza energy intelligence integrated into the app allows battery-electric vehicle drivers to control the charging process via their smartphone. Drivers may choose when their vehicle should be ready and can save money by using the cheapest and cleanest energy. The Hyundai Motor Group and Kaluza have natively integrated the charging control into the group's digital platforms so that drivers can access the features within their familiar app environment. In the UK, Ovo will be the first energy provider to offer smart charging via the Kia App in an initial phase. This will enable Kia drivers who are OVO customers to manage their car and charging in one place. Kia drivers who currently use the Kia App for their vehicle and the OVO Charge App for charging will be able to switch entirely to the Kia App for both by early autumn. This offer will be available to Hyundai drivers shortly after. "We selected Kaluza because of their depth of expertise in energy intelligence and their ability to work with us at the frontier of what's technically possible," says Woong Tae Hwang, Vice President and Head of the EV Energy Strategy Group at Hyundai Motor Group. "This is not just a product integration. We are co-developing the standard for how EVs participate in the energy system, and we expect the rest of the market to follow. That's the kind of partner we needed" "This partnership is about more than smart charging," adds Stephen Fitzpatrick, CEO of Kaluza. "Kaluza and Hyundai Motor Group are building the new industry standard for how electric vehicles integrate with the energy system, starting in the UK and Australia. The market will follow. That's what this kind of co-development is for. It's also a critical first step in building the foundation for vehicle-to-grid services that can reduce energy costs and support the energy transition for years to come." 0 comments. about "Hyundai Group integrates smart charging control from Kaluza"
