华为发布2024智能充电网络十大趋势

　　王志武表示，过去3年，电动汽车持续超预期发展，在未来10年，整个电动汽车的保有量会增长至少10倍，充电量至少增长8倍。充电网络建设不完善仍是整个电动汽车产业的第一痛点，建设高质量的充电网络，将加速新能源汽车渗透，推动本地产业和生态的繁荣。

　　在全球交通电动化和碳中和进程加速的背景下，华为基于深度洞察和思考，发布2024华为智能充电网络十大趋势，希望携手业界早日实现让有路的地方就有高质量充电。

　　趋势一 高质量发展

　　未来践行充电网络高质量发展的四大路径包括顶层的统一规划和设计、底层的统一技术标准、政府的统一监管、用户运营的统一平台。

　　趋势二 全面超充化

　　随着以碳化硅和氮化镓为代表的第三代功率半导体与高倍率动力电池的日益成熟，电动汽车正加速向高压化超充方向发展。预测2028年，高压超充车型占比将超过60%。

　　趋势三 极致体验

　　新能源汽车加速普及，私家车主取代运营车主成为主力军，充电需求由成本优先走向体验优先。

　　趋势四 安全可信

　　随着新能源汽车不断渗透，产业数据量指数级爆发，强电安全与网络安全将变得更加重要。安全可信的充电网络应该具备4大特征：隐私不泄露，车主不触电，车辆不起火，运营不崩溃。

　　趋势五 车网互动

　　电网“双随机性”持续增强，充电网络将成为以新能源为主体的新型电力系统的有机组成。随着商业模式与技术成熟度，车网互动将经历三个重要阶段：从单向有序，逐步走向单向响应，最后实现双向互动。

　　趋势六 功率池化

　　传统一体桩功率不共享，无法解决充电的四个不确定性，即MAP不确定、SOC不确定、车型不确定以及闲忙不确定，造成充电的市电利用率不到10%。因此，充电基础设施将逐步由一体桩架构走向功率池化，以匹配不同车型不同SOC的充电功率需求。通过智能调度，最大化满足全车型充电需求、提升市电利用率、节省建站成本、长期随车演进。

　　趋势七 全液冷架构

　　当前主流的风冷或半液冷的散热模式充电设施模块失效率高、寿命短、极大的增加了场站运营商的维护成本。采用全液冷散热模式的充电基础设施将模块年失效率降低至千分之五以下，寿命长达10年+，不挑部署场景，更低运维成本实现广覆盖。

　　趋势八 慢充直流化

　　园区停充一体是车网互动核心场景，该场景下车辆挂网时间充足，是实现车网互动的基础。但交流桩存在两个大缺陷，一个是无法实现电网互动，不支持V2G演进；二是无法车桩协同，缺乏数字化互联互通。停充一体场景未来会大规模走向小功率直流的充电方案，相比传统交流桩，可带来更快充电、更高市电利用率，长期演进高阶电网互动。

　　趋势九 园区微电网

　　园区未来的发展趋势是“光储充荷车云”一体，通过云端的统一协调管理，实现电网、光伏、储能、车辆、生活负荷的高效协同，低价发电高价充电，经济效益高、电网友好。

　　趋势十 全面智能化

　　当前充电网络数字化程度低，网络、场站、设备、车辆没有协同，形成数字孤岛；未来网络、场站、设备、车辆全面智能化实现“云站桩车”四层协同，高效使能车桩协同、电网互动、全数字营维。

　　风劲正是扬帆时，展望未来，华为将知行合一，持续加大研发和技术投入，打造车主喜爱，运营商信赖，电网友好的智能充电网络解决方案。华为也将联合车企、运营商等伙伴共同构建生态圈，让有路的地方就有高质量充电，让车主出得了城，下得了乡。

On January 30th, Huawei 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 press conference, Wang Zhiwu, President of Huawei's Intelligent Charging Network field, comprehensively interpreted the top ten trends of intelligent charging networks in 2024 from two dimensions: technology and industry. Wang Zhiwu, President of Huawei Intelligent Charging Network
Wang Zhiwu stated that in the past three years, electric vehicles have continued to develop beyond expectations. In the next 10 years, the total number of electric vehicles will increase by at least 10 times, and the charging capacity will increase by at least 8 times. The imperfect construction of charging networks remains the first pain point of the entire electric vehicle industry. Building high-quality charging networks will accelerate the penetration of new energy vehicles and promote the prosperity of local industries and ecology.
Against the backdrop of accelerating global transportation electrification and carbon neutrality, Huawei has released the top ten trends of Huawei's intelligent charging network in 2024 based on deep insights and thinking, hoping to work together with the industry to achieve high-quality charging wherever there is a way.
Trend One: 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 overcharging
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 high-voltage overcharging. It is predicted that by 2028, the proportion of high-pressure and supercharged vehicle models will exceed 60%.
Trend Tripole 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 Five Car Network Interaction
The "double 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 Six 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 Seven 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 over 10 years. It does not require deployment scenarios and achieves wide coverage with lower operation and maintenance costs.
Trend 8 Slow Charging DC
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 will 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 "cloud station pile vehicle" collaboration, efficiently enabling vehicle pile collaboration, power grid interaction, and full digital operation and maintenance.
Fengjin is setting sail and looking forward to the future, Huawei will integrate knowledge and action, continuously increase research and technology investment, and create an intelligent charging network solution that is loved by car owners, trusted by operators, and grid friendly. Huawei will also collaborate with car companies, operators and other partners to build an ecosystem, allowing high-quality charging wherever there is a road, allowing car owners to leave the city and go to the countryside.
