Huawei’s Electric Vehicle Charging Technology & Top 10 Charging Trends
Huawei EV Charging Backgrounder –from Google Gemini:
Huawei is a major player in the electric vehicle (EV) charging infrastructure market, focusing primarily on developing and supplying ultra-fast, liquid-cooled charging solutions and related smart energy management systems. Their involvement includes manufacturing core charging hardware and developing software/AI for intelligent network management.
Key aspects of Huawei’s involvement in charging technology:
- Ultra-Fast Charging Technology: Huawei’s flagship product is the FusionCharge system, which uses a fully liquid-cooled design to enable ultra-fast DC charging at high power levels, including up to 600 kW and even experimental 1.5 MW chargers. This technology is designed to add significant range (e.g., over 200 km in 5 minutes) and is compatible with most EV models.
- Integrated Energy Solutions: A core part of their strategy is the integration of EV charging with renewable energy (photovoltaics or PV) and energy storage systems (ESS). This “PV+ESS+Charger” solution helps maximize green power consumption, reduces the impact of high-power charging on the main power grid, and allows for intelligent peak shaving to optimize operational costs.
- Hardware and Components: Huawei designs and supplies key charging components, including power units, charging dispensers, and silicon carbide (SiC) chips that enhance efficiency and power density. Their modular designs allow for scalable power output and a service life of over 10 years.
- Smart Network Management: Huawei provides platforms for smart charging network management that enable remote monitoring, data analysis, and intelligent power distribution among multiple vehicles at a single station. This intelligent power pooling improves efficiency and ensures optimal use of available power.
- Innovation in Convenience: Huawei has showcased an experimental prototype of a robotic charging arm that can automatically locate and plug into a vehicle’s charging port, facilitating a seamless “self-charging” experience that would work well with autonomous vehicles.
- Strategic Partnerships and Market Deployment: Huawei works with partners, including logistics companies and car manufacturers, to deploy its charging solutions across China and other markets. They are also involved in joint ventures for manufacturing EVs, such as with Chery under the Harmony Intelligent Mobility Alliance (HIMA).
- Battery Technology Research: The company holds patents for advanced battery technology, including a solid-state battery with a high energy density, which could further revolutionize EV range and charging times if commercialized.

Here are Huawei’s top 10 trends in charging systems for electric vehicles:
- From passenger vehicles to commercial vehicles, “high quality” has become a must for ultra-fast charging infrastructure, driving large-scale upgrade of legacy charging devices to meet the energy needs of different vehicle models. High-quality development will extend from “cities of ultra-fast charging” to “cities of megawatt charging” through unified planning, standards, supervision, and O&M, enabling industry partners to turn high quality into high returns.
- Ultra-fast-charging vehicle models, once premium necessities, will be embraced by everyone. The extensive application of third-generation power semiconductor materials and high-C-rate traction batteries will further increase the market share of ultra-fast-charging vehicles. Megawatt-charging commercial vehicles will dominate the market.
- Megawatt-Scale Logistics Electrification: “Fuel-to-electricity” conversion for viable business will rapidly expand Heavy Goods Vehicle (HGV) from limited, closed applications to widespread, all-scenario adoption. The cost reduction of traction batteries and the innovation of megawatt charging technologies will make megawatt-scale logistics electrification an unstoppable trend, bringing significant economic and social values.
- 100 Megawatt Scale Charging Stations: For electrified logistics, 100 MW-scale charging stations will become the essential infrastructure for high-throughput operations. Factors such as technical strengths, competitive electricity pricing, and scalable deployment will unlock powerful cluster effects and secure long-term, sustainable profitability for charging station investments.
- Security and Trustworthiness: Compared with passenger vehicles, commercial vehicles require higher charging power and a greater proportion of energy storage system (ESS) capacity in charging stations. Therefore, security and trustworthiness will become fundamental requirements for charging networks. The comprehensive electrical safety protection architecture will seamlessly safeguard people, vehicles, and chargers, reinforced by a robust cybersecurity foundation.
- Liquid-cooled ultra-fast charging delivers superior heat dissipation and protection, enabling reliable performance across increasingly distributed charging scenarios. In contrast, conventional air-cooled systems struggle in demanding environments such as high heat, humidity, salt fog, and heavy dust. In the future, the liquid cooling technology will be applied in vehicles and chargers, enabling efficient megawatt charging and contributing to overall vehicle cost reduction.
- A DC-based ESS+charger system can effectively increase power capacity, helping customers quickly and cost-effectively deploy ultra-fast charging stations, even in locations with limited grid power. This system is ideal for upgrading legacy low-capacity stations, enabling ultra-fast charging stations to be rapidly repurposed or newly deployed with minimal grid power, and maximizing the capability to meet vehicle charging demands.
- Modular Station Construction: The station-level modular solution is built for engineering construction and device commissioning, adapting to a wide range of charging scenarios. Its low cost, rapid deployment, and easy relocation make it a flexible choice, while its durable design ensures long-term value and protection for investors.
- Campus Microgrid: The grid-forming PV+ESS system integrates the liquid-cooled ultra-fast charging technology, and can operate in on-grid or off-grid mode. This forms a one-stop “PV+ESS+charger+vehicle+network” solution that boosts power capacity, maximizes the use of green energy, and enhances revenue through time-of-use arbitrage.
- AI Empowerment: The intelligent evolution of charging networks will enable seamless collaboration across networks, stations, chargers, and vehicles. By breaking down digital silos, it will elevate the end-to-end charging experience for vehicle owners and enhance overall logistics and transportation efficiency.
Huawei says they will continue to work with partners to accelerate the rollout of seamless, high-quality ultra-fast charging networks, and capture opportunities of mobility electrification.
