Huawei released the top 10 smart charging network trends 2024 on January 30, with the theme “High-quality charging anywhere.” At the event, Wang Zhiwu , President of Huawei Smart Charging Network Domain, comprehensively interpreted these trends from technology and industry perspectives.
Wang Zhiwu highlighted that electric vehicles (EVs) have exceeded growth expectations in the past three years. In the next decade, the number of electric vehicles on the road is expected to increase tenfold and demand for electric vehicle charging to increase eightfold. As the immature charging network is still the main problem of the entire electric vehicle industry, building a high-quality charging network will accelerate the penetration of new electric vehicles (NEVs) and boost the local industry and ecosystem. .
As the world accelerates towards mobility electrification and carbon neutrality, Huawei released the top 10 smart charging network trends 2024 based on detailed insights and aspirations for high-quality charging anywhere together with industry partners. industry.
Trend 1: High-quality development
The industry collectively strives to achieve high-quality development of charging networks through unified planning and design, unified technical standards, unified government supervision, and unified operation and maintenance for users.
Trend 2: Integral ultra-fast charging
With the maturity of third-generation power semiconductors and high-speed C traction batteries using materials such as silicon carbide and gallium nitride, electric vehicles are heading into the domain of ultra-fast high-voltage charging. . High-voltage ultra-fast charging vehicle models are expected to account for more than 60% of total vehicle models in 2028.
Trend 3: Optimal experience
With NEVs rapidly gaining popularity, passenger vehicle owners replace commercial vehicle owners as primary users and thus widespread charging preference shifts from low cost to optimal experience.
Trend 4: Safety and reliability
With the continued penetration of NEVs, the industry’s explosion in data volume poses major challenges to ensuring electrical safety and cybersecurity. A secure and reliable charging network has no privacy leaks, electric shocks, fires or service failures.
Trend 5: Vehicle-grid interaction
As the grid faces greater randomness in power generation and consumption, the charging network will play a vital role in an electricity system dominated by renewables. Along with the growth path of business models and technologies, vehicle-network interaction will go through three key phases: one-way coordination, one-way response and two-way interaction.
Trend 6: Energy Pooling
Charging facilities are moving from integrated charger architecture to power pooling architecture to meet the charging power requirements of different vehicle models at different SOC levels. Additionally, intelligent scheduling meets the charging requirements of all vehicle models and helps improve grid energy utilization, reduce site construction costs, and support long-term vehicle evolution.
Trend 7: Fully liquid-cooled cargo
Fully liquid-cooled charging facilities, compared to air-cooled or semi-liquid ones, feature an annual failure rate of less than 5‰, a service life of more than 10 years, and adaptability to various environments, dramatically reducing costs. operation and maintenance costs.
Trend 8: Normal DC Power Charging
In future campuses with integrated parking and charging, small-power DC charging solution will be more popular and applied on a large scale. Compared with traditional AC chargers, the DC charging solution will achieve optimal charging, higher grid energy utilization, and long-term evolution towards V2G interaction.
Trend 9: Campus Microgrid
Future campuses are likely to integrate PV, ESS, chargers, loads, vehicles and cloud systems through unified cloud-based management to achieve greater economic benefits of electricity and grid compatibility.
Trend 10: All intelligence
The lack of an advanced digital charging network has led to isolated management of networks, stations, devices and vehicles. This will change as these isolated parts are integrated into a smart charging network to facilitate vehicle-charger collaboration, vehicle-grid interaction, and digital operation and maintenance.
