Global electric vehicle market enters a new phase of transformation: modular platforms and battery technology become competitive focal points.

Introduction

The global electric vehicle market is at a new turning point. According to the latest report by Frost & Sullivan, *OEM Strategies on Next Generation Electric Vehicles, Global, 2025–2031*, global battery electric vehicle (BEV) sales are expected to grow from approximately 17.8 million units in 2025 to about 32.6 million units in 2031, with market growth accelerating further after 2027. Behind this growth lies the systematic investment by OEMs in modular platforms, battery technology, supply chain integration, and charging infrastructure—the global electric vehicle industry is entering a new phase of transformation centered on an "integrated ecosystem."

Industry Background

In the past few years, the global EV market has transitioned from policy-driven to market-driven growth, yet high costs, charging anxiety, and supply chain bottlenecks have remained key obstacles. Frost & Sullivan notes that the current market is in a "critical phase," where affordability, manufacturing efficiency, and technological differentiation will determine long-term competitiveness. As Chinese manufacturers (e.g., BYD, NIO) expand globally with cost advantages and rapid iteration capabilities, traditional automakers face increasing pressure to reshape their electrification strategies. Meanwhile, stricter emissions regulations worldwide are accelerating OEMs' transition to electrification.

Key Progress

The report shows that OEMs are shifting from independent electrification strategies to integrated ecosystems, with core initiatives including:

• Modular platform adoption: Standardized modular platforms support multiple models and battery chemistries, significantly reducing R&D costs and enabling mass production of affordable vehicles. Examples include Volkswagen's MEB platform and Tesla's next-generation platform.
• Battery technology diversification: In addition to improving existing lithium-ion battery performance, OEMs are accelerating investments in sodium-ion batteries, solid-state batteries, and 800V high-voltage architectures to shorten charging times and improve energy efficiency.
• Vertical supply chain integration and localization: To reduce dependence on external suppliers and address geopolitical risks, automakers are strengthening vertical integration in battery production and raw material sourcing, while building localized manufacturing capabilities in key markets.
• Charging network collaboration: OEMs are partnering with charging operators to build ultra-fast charging networks and exploring energy service models such as V2G (vehicle-to-grid).

Frost & Sullivan analyzed the strategies of BMW, BYD, Ford, General Motors, Hyundai, Mercedes-Benz, NIO, Stellantis, Tesla, Toyota, VinFast, and Volkswagen, concluding that the greatest growth opportunities in the coming years will come from four areas: battery technology, charging infrastructure, resilient supply chains, and manufacturing transformation.

Industry ImpactImpact on Global Automakers: The proliferation of modular platforms will lower the barriers to developing new models, enabling even small and medium-sized automakers to quickly launch electric vehicles, but it will also intensify homogeneous competition. The cost advantages of Chinese automakers are forcing traditional OEMs to accelerate innovation—for example, GM and Ford have already announced plans for new-generation electric platforms.

Impact on Battery Supply Chain: R&D investment in sodium-ion and solid-state batteries could reshape the current dependence on scarce resources like lithium and cobalt. Meanwhile, the widespread adoption of 800V high-voltage architectures will drive demand for silicon carbide (SiC) power modules, benefiting relevant suppliers.

Impact on Charging Infrastructure: The commercial deployment of ultra-fast charging (350kW+) and V2G technology will enhance charging convenience and spawn new energy service models. Charging operators will need to deeply integrate with automakers to match charging protocols across different platforms.

Impact on Manufacturing and Employment: The trend toward localized manufacturing will reshape the global automotive industry's geographic landscape. Traditional automotive manufacturing centers (e.g., Europe, the U.S.) may see a wave of investment in battery factories and electric drive systems, but they will also face challenges from workforce skill transitions.

Challenges and Risks

Despite the optimistic outlook, the transformation process still faces multiple challenges:

• Cost Pressure: Can battery costs decline faster than subsidy phase-outs? Raw material price volatility remains a concern.
• Technology Pathway Uncertainty: The commercialization timeline for solid-state batteries has been repeatedly delayed, and sodium-ion batteries have limited energy density. OEMs must balance investment across multiple technology pathways.
• Infrastructure Lag: The global pace of charging station construction still lags behind EV growth, especially in rural areas and along long-distance corridors.
• Geopolitical Risks: Trade barriers, tariffs, and supply chain decoupling risks could drive up manufacturing costs and impact global deployment.

Future Outlook

Frost & Sullivan expects significant acceleration in market growth after 2027, as low-cost EVs will flood the market and major economies will further tighten emission regulations. Modular platforms will become the industry standard, and battery technology will shift from "pursuing energy density" to "overall cost-effectiveness" and "fast-charging capability." Furthermore, the integration of charging networks with renewable energy (e.g., photovoltaic + storage + charging) will promote deep integration of the transportation and energy systems.

Conclusion

The "new phase" of the global EV market is not just about sales growth—it is a fundamental shift in the industry's underlying logic: from individual vehicle development to platform-based ecosystems, from single battery solutions to diversified technology portfolios, and from reliance on subsidies to cost and efficiency drivers. This transformation will profoundly impact the entire value chain, from raw materials to charging operations, and accelerate the global electrification of transportation. With the combined effects of modular platforms, battery localization, and charging infrastructure, EVs are expected to become the dominant mode of mobility around 2030.
