Huawei Releases Top 10 Trends in 2024 Intelligent Charging Networks

Article Source：KuaiTech | Author：KuaiTech | Issuing Time：2024.03.19
On January 31st, KuaiTech reported that Huawei recently held a press conference on the top ten trends of intelligent charging networks in 2024, with the theme of "where there is a way, there is high-quality charging". At the conference, Wang Zhiwu, President of Huawei's intelligent charging network field, interpreted the top ten trends of intelligent charging networks in 2024.


Trend 1: High quality development

The four major paths for implementing high-quality development of charging networks in the future include unified planning and design at the top, unified technical standards at the bottom, unified government supervision, and a unified platform for user operation.

Trend 2: Comprehensive super fast charging

With the increasing maturity of third-generation power semiconductors and high rate power batteries represented by silicon carbide and gallium nitride, electric vehicles are accelerating their development towards ultra fast charging. It is predicted that by 2028, the proportion of super fast charging models will exceed 60%.

Trend 3: Ultimate Experience

The accelerated popularization of new energy vehicles has led private car owners to replace operating car owners as the main force, and the demand for charging has shifted from cost priority to experience priority.

Trend 4: Security and trustworthiness

With the continuous penetration of new energy vehicles and the exponential explosion of industrial data, strong electricity security and network security will become more important. A safe and reliable charging network should have four major characteristics: privacy is not leaked, car owners are not electrocuted, vehicles are not on fire, and operations are not disrupted.

Trend 5: Car Network Interaction

The dual randomness of the power grid continues to strengthen, and the charging network will become an organic component of a new type of power system dominated by new energy. With the maturity of business models and technology, car network interaction will go through three important stages: from one-way order, gradually moving towards one-way response, and finally achieving two-way interaction.

Trend 6: Power Pooling

The traditional integrated pile does not share power, which cannot solve the four uncertainties of charging, namely MAP uncertainty, SOC uncertainty, vehicle model uncertainty, and idle uncertainty, resulting in a charging utility rate of less than 10%.

Therefore, the charging infrastructure will gradually move from an integrated pile architecture to power pooling to match the charging power requirements of different vehicle models and SOC. Through intelligent scheduling, it maximizes the satisfaction of the charging needs of all vehicle models, improves the utilization rate of electricity, saves station construction costs, and evolves with the vehicle in the long term.

Trend 7: Full liquid cooling architecture

The current mainstream air-cooled or semi liquid cooled cooling mode for charging facility modules has a high failure rate, short lifespan, and greatly increases the maintenance cost for station operators.

The charging infrastructure that adopts a fully liquid cooled cooling mode reduces the module's annual failure efficiency to below 0.5%, with a lifespan of up to 10 years. It does not require deployment scenarios and achieves wide coverage with lower operation and maintenance costs.

Trend 8: Slow charging DC conversion

The integration of park parking and charging is the core scenario of vehicle network interaction. In this scenario, there is sufficient time for vehicles to be connected to the network, which is the foundation for achieving vehicle network interaction.

But there are two major flaws in the communication pile, one is that it cannot achieve grid interaction and does not support V2G evolution; The second issue is the inability to coordinate vehicles and piles, and the lack of digital interconnectivity.

In the future, the integrated scenario of charging and stopping will move towards low-power DC charging solutions on a large scale. Compared to traditional AC piles, it can bring faster charging, higher electricity utilization efficiency, and long-term evolution of higher-order grid interaction.

Trend 9: Park Microgrid

The future development trend of the park is to integrate solar energy storage, charging, and vehicle cloud. Through unified coordination and management of the cloud, efficient collaboration between the power grid, photovoltaic, energy storage, vehicles, and living loads can be achieved. Low price power generation and high price charging result in high economic benefits and grid friendliness.

Trend 10: Comprehensive Intelligence

The current level of digitalization in charging networks is low, and there is no coordination among networks, stations, equipment, and vehicles, forming a digital island; In the future, the comprehensive intelligence of networks, stations, equipment, and vehicles will achieve four layers of collaboration, including cloud station, pile, and vehicle, efficiently enabling vehicle pile collaboration, power grid interaction, and fully digital operation and maintenance.

It is worth mentioning that in December last year, Huawei announced its plan to deploy over 100000 Huawei fully liquid cooled ultra fast charging stations in over 340 cities and major roads nationwide by 2024, achieving high-quality charging wherever there are roads.
