Huawei is actively marketing its FusionCharge integrated charging system to European fleet and depot operators, promoting a hardware stack that bundles solar generation, battery storage, and high-power EV chargers into one platform — and positioning the combination as the answer to Europe’s grid capacity crisis. What the company’s promotional materials did not mention: the European Commission froze EU Investment Bank funding for projects using Chinese solar inverters in May 2026, citing the risk that such components could, in a worst-case scenario, destabilize European energy infrastructure and trigger blackouts. FusionCharge’s integrated design depends on exactly those components.
The platform, developed under Huawei’s Digital Power division, was showcased at the Power2Drive Europe 2026 showcase in Munich in late June. Coverage of the showcase this week, including on the trade outlet electrive.com, was published as a Huawei-commissioned advertorial — paid content in which Huawei itself is the author of record.
That sourcing matters. Nearly every specific technical claim in circulation about FusionCharge’s efficiency, payback period, and deployment reach originates from Huawei’s own internal lab tests. Huawei’s own product documentation states explicitly that performance figures “are based on theoretical values obtained by Huawei internal labs through tests carried out under specific conditions” and that “actual performance may vary.” No independent third-party security audit or performance benchmark for the FusionCharge platform has been published.

The engineering argument behind FusionCharge is specific and legitimate. Europe’s charging infrastructure faces a structural constraint that has slowed deployment at commercial and highway sites: getting adequate power to a location requires a grid connection application process that can take months, reconstruction costs that can run into hundreds of thousands of euros, and in some cases a grid capacity simply does not exist on a timeline that matches operator development schedules.
FusionCharge’s DC-coupled BESS design directly addresses this. By connecting a battery energy storage system (BESS) to a shared DC bus with the solar array — rather than running solar through a separate AC inverter — the platform reduces the number of energy conversions in the system. Solar electricity generated on a depot roof flows directly into the battery as DC, bypasses an AC conversion step, and is dispatched as DC to the charging dispensers when vehicles connect. Only one DC-to-AC conversion occurs when power is sent to the grid or to AC loads. This is the core technical distinction between DC coupling and the older AC-coupled architecture, where energy moves DC→AC→DC→AC, accumulating conversion losses at each step.
The practical result: a charging cluster of up to 12 connectors, backed by a battery that stores off-peak grid power and solar generation, can operate with a minimum grid connection of just 50 kW (33 kilowatts is typical for a single residential home in many markets; a conventional ultra-fast charging hub without storage might require ten or twenty times that). According to Huawei, this design enables new charging station deployments in as little as one week, compared to months for conventional grid-upgrade approaches.
The efficiency Huawei claims for this architecture — 92.1% round-trip efficiency (RTE) — sits at the low end of the range independent technical sources report for DC-coupled systems. Industry benchmarks for DC-coupled systems consistently place the standard range between 92% and 96%, with the efficiency advantage over AC-coupled systems (88%–92% RTE) meaningful but not dramatic. Huawei’s stated figure is consistent with the architecture — it is not exceptional.
The liquid-cooled power unit supports up to 720 kW of output with 500 amperes (A) per connector — specs oriented toward both current high-voltage passenger EVs and heavy goods vehicles. A separate 1,500 kW megawatt-class system targets logistics hubs where trucks need significant charge added in roughly 15 minutes.
Huawei says dynamic power allocation allows vehicles with tight turnaround windows to receive maximum available power while trucks in an overnight shift charge more slowly, drawing less from the grid and battery. A basic energy management system is built into FusionCharge; more complex requirements — building energy management, load forecasting, solar yield prediction — can be connected from third-party providers.
Alexander Wieler, Huawei’s Principal EV Charging Business Development Director for Europe, made the commercial case in remarks that appeared in the Huawei-commissioned advertorial on electrive.com: “The market is ready. Everything is becoming so much more connected and so much more complex.” He described fleet and depot operators combining rooftop solar, battery storage, and managed charging as “something we are very, very strong at.”
The market Wieler described is real. Commercial vehicle electrification is accelerating across European markets, bus fleets are converting under regulatory pressure, and depot operators typically control rooftop space that suits solar installation. The integrated approach FusionCharge represents — treating energy generation, storage, and dispensing as one managed system rather than three separate infrastructure procurements — reflects a genuine direction the industry is moving.
But the market’s complexity extends well beyond grid connections and dynamic power allocation. Huawei’s deployment footprint in Europe spans operations in Italy, the Netherlands, and dozens of other markets. The platform’s network management layer — which enables remote monitoring, data analysis, and intelligent power distribution across all connected hardware — routes operational data through Huawei’s cloud management platform. That cloud infrastructure is subject to the same legal obligations as all Huawei operations globally.

Before evaluating FusionCharge as a fleet infrastructure decision, operators need to understand the legal framework in which Huawei operates. This is not a negotiable term or a risk to be weighed against price. It is a fixed legal condition.
China’s National Intelligence Law (2017), Article 7 states: “All organizations and citizens shall support, assist, and cooperate with national intelligence efforts in accordance with law, and shall protect national intelligence work secrets they are aware of.” The U.S. Department of Homeland Security has confirmed that this obligation applies to Chinese companies even when their equipment operates outside the PRC. The FCC’s 2020 ruling found the law “broad enough to allow the Chinese government to compel Chinese companies such as Huawei to assist it in its espionage activities.”
China’s Cybersecurity Law (2017) adds a separate requirement: network operators must provide “technical support and assistance” to public security organs upon request and store select data within China. The CSIS analysis of China’s cyber supply chains documents how these legal obligations interact with Chinese companies’ infrastructure roles globally.
China’s Data Security Law (2021) adds data localization and government-access provisions.
Huawei has stated it has never shared user data with the Chinese government and would not do so. The Cipher Brief, analyzing this claim in July 2025, concluded that both Huawei and TikTok “would be in violation of China’s law if they refused the demands of their intelligence services for cooperation” — meaning the legal constraint applies regardless of the company’s stated policy.
The data the FusionCharge network management platform collects from deployed hardware — charging session data, vehicle identification, grid load patterns, energy flow data, site-level power consumption — falls within the categories of operational data that could be subject to such requests.
An FBI investigation in 2022 found that Huawei equipment can be used to disrupt U.S. military communications. The CSIS analysis separately documents a 2019 independent security audit by Finite State that found frequent backdoor-like vulnerabilities in Huawei firmware that would enable remote access and control of devices, with no similar vulnerabilities found in Western competitors’ network equipment. Vodafone’s security team separately found that some Huawei maintenance interfaces allow persistent access and control.
No independent security audit of FusionCharge EV charging equipment or the associated network management platform has been published.
The regulatory risk is not theoretical or pending. It materialized in May 2026.
On May 4, 2026, the European Commission announced it was freezing EU Investment Bank and partner-bank funding for clean energy projects that use solar inverter components from manufacturers in high-risk countries. An EU official stated the Commission had “identified serious economic and cybersecurity risks” from Chinese solar inverters and that the findings, drawing on classified evidence from multiple member states, indicated that Chinese actors could, in a worst-case scenario, “undermine European energy infrastructure, potentially even triggering blackouts.”
Reuters and other outlets reported that U.S. engineers had discovered undocumented rogue communication devices in some Chinese-made solar inverters — equipment that, sources said, could allow for remote circumvention of firewalls. This documented in a May 2026 procurement advisory alongside Germany’s Federal Office for Information Security (BSI), which explicitly warned of “manipulation of energy infrastructure by manufacturers or third parties” in solar power systems. The Czech Republic’s national cybersecurity agency issued a similar warning in September 2025.
Approximately 80% of PV inverters imported into the EU come from Chinese manufacturers, with Huawei controlling an estimated 220 gigawatts (GW) of Europe’s installed solar capacity. The EU Commission’s January 2026 proposed Cybersecurity Act revision (CSA2) would create a binding “high-risk vendor” framework — in trilogue negotiations as of this writing, with political agreement targeted for early 2027 — that could ultimately ban covered equipment from the EU market entirely, carrying penalties of up to 7% of turnover for violations.
For FusionCharge specifically, the practical impact of the May 2026 funding restriction is immediate: a charging operator seeking EU Investment Bank or partner-bank financing for a depot or fleet charging installation that incorporates Huawei’s integrated PV+BESS+Charger stack will find that financing is no longer available for the solar inverter and power conversion components at the core of the platform.
Stripping away the regulatory and security dimensions, the FusionCharge platform solves a genuine engineering problem with a well-established architectural approach. DC coupling is an efficient, proven method for integrating solar generation with battery storage, and Huawei’s ability to manufacture across the full hardware chain — solar inverters, battery packs, liquid-cooled charging dispensers — gives it a cost coherence advantage that narrowly focused rivals will find difficult to replicate quickly.
Competitors including ABB and Siemens have been developing convergent energy-and-charging offerings, but neither has the same vertical integration across the hardware stack. The standalone fast charger plugged into the grid with no local generation or storage buffer is increasingly a first-generation artifact; the integrated model FusionCharge represents is where the industry is heading.
Whether Huawei can deliver that integrated model in Western European markets at competitive scale is a different question, and the answer is not simply technical. The FCC in the United States added all devices containing Huawei chips to its covered-equipment ban in a July 22, 2026 action. Germany is required to remove Huawei equipment from its 5G core networks by the end of 2026, with management systems from access and transport networks to follow by 2029. Several EU member states have restricted Huawei from 5G infrastructure entirely; others continue purchasing Huawei equipment for sensitive applications despite Commission guidance.
The openness argument Huawei makes — that FusionCharge works with any third-party CPMS, EMS, or payment system — addresses one set of concerns from CPO networks standardized on existing software. It does not address the legal framework that applies to the hardware.
If a fleet operator or CPO is currently evaluating FusionCharge, several steps are worth completing before a procurement decision:
Confirm EU financing eligibility by contacting the EU Investment Bank or the relevant national partner bank to verify whether the specific Huawei components in the proposed configuration are subject to the May 2026 funding restrictions.
Network segmentation: ensure Huawei charging hardware is isolated from facility IT networks and from any systems handling sensitive operational or personnel data.
Contractual data terms: review what Huawei’s service agreement specifies regarding data retention, cloud routing, and government access — bearing in mind that contractual commitments by Huawei cannot supersede Chinese law.
Consult national cybersecurity agency guidance: BSI (Germany), NUKIB (Czech Republic), and CISA (United States) have each published relevant guidance on Chinese infrastructure hardware.
Request air-gapped operation specifications: ask whether FusionCharge can operate in a fully local, cloud-disconnected configuration and what functionality is lost if the network management connection is severed.
No mitigation fully eliminates the structural legal risk. China’s National Intelligence Law applies to Huawei regardless of where its equipment is installed or how data is routed locally.
Not fully. The European Commission froze EU Investment Bank and partner-bank financing for projects incorporating Chinese solar inverter and power conversion components in May 2026, citing cybersecurity and grid-stability risks. FusionCharge’s integrated platform depends on exactly those components. Operators pursuing EU-financed charging infrastructure should confirm component eligibility before procurement by contacting the EU Investment Bank funding freeze guidance directly.
The EU Cybersecurity Act revision proposal (CSA2), proposed in January 2026 and currently in trilogue negotiations, would create a binding “high-risk vendor” framework. If adopted as proposed — with political agreement targeted for early 2027 — it could bar designated high-risk suppliers from the EU market for covered technology categories including solar energy systems. Huawei and ZTE have already been named by Commission officials as the primary targets of the framework.
FusionCharge’s cloud-connected smart charging network management platform collects charging session data, vehicle identification, energy flow data, and grid load information from deployed hardware. This data is subject to China’s National Intelligence Law (2017), which requires all Chinese organizations to cooperate with state intelligence requests regardless of where equipment is located or where data is initially collected. China’s Cybersecurity Law (2017) separately requires network operators to provide technical support and assistance to public security organs upon request. Huawei has denied sharing user data with the Chinese government, but The Cipher Brief noted in July 2025 that the company would be in violation of Chinese law if it refused such a demand.
In a DC-coupled battery energy storage system, solar panels and batteries share the same direct-current bus, so electricity generated by rooftop solar flows directly into the battery without being converted to alternating current first. Only one DC-to-AC conversion occurs when power is dispatched to vehicles or to the grid. This means fewer conversion losses than an AC-coupled system, where energy is converted multiple times. Independent technical sources place industry-standard DC-coupled round-trip efficiency between 92% and 96% — Huawei’s claimed 92.1% sits at the low end of this range. The practical value for fleet operators is that the battery can bridge peak demand without drawing heavily on the grid, reducing the size and cost of the grid connection required.
