At a conference on high-quality charging recently held by Huawei, the ten leading trends in electric vehicle software and energy replenishment infrastructure were discussed.
Huawei presented the 10 Charging Network trends for 2024 at its conference, "High Quality Charging Everywhere". In the presentation, Wang Zhiwu, President of Huawei Smart Charging Network Domain, noted that electric vehicles (EVs) have grown beyond expectations over the past three years.
According to Huawei, which will play an important role in automotive software, the number of electric vehicles will increase at least tenfold over the next decade, while charging demand will increase eightfold.
With the charging network still at an early stage of development and remaining the main weak point in the electric mobility industry, building a high-quality charging network will accelerate EV adoption and strengthen local industry and the ecosystem.

As the transition to electric mobility accelerates and efforts to reduce carbon emissions gather pace, Huawei, together with industry partners, announced the 10 leading 2024 Charging Network trends, based on in-depth data and aimed at delivering high-quality charging everywhere.
High-quality development
High-quality development of the charging network is a common goal for the entire industry. To achieve it, there are four key priorities: unified planning and design, unified technical standards, unified government oversight, and unified O&M operations for users.
Integrated ultra-fast charging
With the development of third-generation power semiconductors and high-C-rate traction batteries using materials such as silicon carbide and gallium nitride, electric vehicles are moving toward high-voltage ultra-fast charging.
High-voltage ultra-fast-charging models are expected to account for more than 60% of all models in 2028.
Optimal experience
Electric vehicles are becoming widely adopted at a rapid pace, as commercial vehicle owners join passenger vehicle owners as key users. As a result, the main priority for charging is shifting from low cost to an optimal experience.
Safety and reliability
As electric vehicles continue to gain ground, the industry is facing an exponential increase in data volumes, presenting major challenges in ensuring electrical safety and cybersecurity.
A safe and reliable charging network prevents privacy breaches, electric shocks, fires, and service outages.
Vehicle-to-Grid Interaction
Since energy generation and consumption on the grid cannot be predicted, the charging network will play a pivotal role in the new power system, where renewable energy is the primary source.
As business models and technologies develop, vehicle-to-grid interaction will pass through three key stages: one-way coordination, one-way response, and two-way interaction.
Power Pooling
Charging facilities are shifting from an onboard charger architecture to a power-pooling architecture to meet the charging power requirements of different vehicle models at different SOC levels.
In addition, intelligent scheduling meets the charging needs of all vehicle models and helps improve the utilization of the power supply network, reduce charging site construction costs, and support the long-term development of vehicles.
Fully liquid-cooled charging
Charging systems that rely primarily on air cooling or semi-liquid coolinghave high annual failure rates and short lifespans, significantly increasing costs their maintenance.
Conversely, charging systems that use liquid-cooling technology have a lower annual failure rate, below 5‰, and a lifespan of more than 10 years. They can be installed in a variety of environments, reducing O&M costs.
“Normal-power” DC charging
AC chargers have two significant drawbacks: they do not support V2G technology in the future, and they lack vehicle-charger interaction due to the absence of digital tools.
In the coming years, charging solutions using low-power DC chargers will become more popular and will be widely adopted in buildings and facilities with parking and charging areas. Compared with AC chargers, DC charging will enable optimized charging, greater utilization of the power supply network, and long-term development of V2G interaction.
Facility microgrid
In the future, buildings and facilities are likely to use photovoltaic systems, energy storage systems (ESS), chargers, the grid, vehicles, and cloud systems simultaneously, managed together through a unified cloud-based system to achieve greater economic benefits from electricity and improve grid-friendliness.
Intelligence
The isolated management of grids, stations, devices, and vehicles is due to the lack of an advanced digital charging network. In the future, they will be integrated into a smart charging network to facilitate vehicle-charger collaboration, vehicle-grid interaction, and digital operation and maintenance (O&M).
Huawei is committed to increasing its investments in R&D and technology, developing charging network solutions that benefit vehicle owners, are reliable for users, and are friendly to the power grid.
The company will work with automakers and operators to create an ecosystem that provides high-quality charging everywhere and enables vehicle owners to travel wherever they wish.
