New trends in technological development
1. Increasing power
The power of charging modules is constantly increasing. From the initial 3kW and 7.5kW, it has gradually developed to the current 20kW, 30kW and 40kW, and even to higher power levels such as 50kW, 60kW and 100kW. This change significantly shortens the charging time and improves user convenience, while also meeting the charging needs of large-capacity battery electric vehicles.
2. Expanding the voltage range
The output voltage range of the charging module has been expanded from 200V to 750V, 1000V, and even higher to be compatible with battery systems of different models, especially those new electric vehicles that use 800V and above voltage platforms. Such a wide voltage adaptability improves the versatility of the charging module and provides support for the diverse electric vehicle market.
3. Improve conversion efficiency
Currently, the peak efficiency of the charging module has reached 95%-96%. By using SiC MOSFET to replace traditional IGBT devices, combined with optimized circuit design and control algorithms, the conversion efficiency is expected to exceed 97.5% in the future. Efficient energy conversion can not only reduce energy loss during charging, but also reduce the heat dissipation requirements of the equipment, thereby improving the stability and service life of the system.
4. Application of liquid cooling technology
In order to cope with the thermal management challenges brought by high-power charging, liquid cooling technology is becoming an important direction for future charging modules. The liquid cooling system effectively dissipates heat through circulating coolant, can withstand higher currents, and ensure stable operation of the module during high-power charging. This technology is particularly suitable for ultra-fast charging scenarios. With the maturity of technology and the reduction of costs, liquid-cooled charging modules are expected to be widely used.
5. Diversified functions
The bidirectional charging function (V2G) is gaining more and more attention, supporting charging and discharging, with an efficiency of more than 95%. Users can charge when the grid load is low, discharge to the grid during peak hours, and even provide power to external loads such as homes. This function not only improves the flexibility of the grid, but also promotes the application of green energy in the field of electric vehicle charging.
6. Standardization and interoperability
The standardization of charging interfaces is crucial in future development. Europe and the United States mainly use CCS (Combined Charging System), Japan uses CHAdeMO, and China uses GB/T standards. In the future, countries may further unify interface standards to enhance global compatibility and reduce user troubles when charging.
7. Improve safety and reliability
Fireproof and explosion-proof design: Use advanced cooling systems and flame-retardant materials to ensure the safety of high-power charging and reduce the risk of fire and explosion.
Network security protection: With the continuous deepening of the digitalization of charging facilities, it is particularly important to further enhance the network security of the charging system to prevent hacker attacks and data leakage and ensure the security of user information.
Fault monitoring and maintenance: Use the Internet of Things (IoT) technology to monitor the status of charging piles in real time, perform maintenance in a timely manner, improve the operating reliability of equipment, and enhance user trust.
8. Intelligent and digital transformation
With the help of AI and DSP technology, charging modules are gradually realizing the integration of edge computing capabilities and advanced software algorithms to promote intelligent management and full digital control. By real-time monitoring and prediction of module life, the operation and maintenance pressure can be reduced, and the operating efficiency and safety of charging facilities can be improved. In addition, the intelligent charging system can dynamically adjust the charging strategy according to the grid load and user demand to maximize energy utilization efficiency.
Market development trend
1. Rapid growth of market size and demand
With the rapid development of the global new energy vehicle market, the scale of the charging module market is also expanding. It is expected that the global market size will reach 9.473 billion yuan in 2023 and will increase to 92.885 billion yuan by 2030, with a compound annual growth rate of 39.58%. Consumers' increasingly urgent demand for fast charging and convenient charging has promoted the advancement of charging module technology and the expansion of the market size.
2. Dominance of the Chinese market
China is the world's largest charging module market, with a market size of 78.30% of the world in 2023, and this proportion is expected to rise further by 2030. This rapid growth is due to policy support, a large number of new energy vehicles, and the continuous construction of charging infrastructure. The Chinese government actively promotes the layout of charging networks, encourages companies to increase R&D investment, and promote technology upgrades.
3. Huge potential of the North American market
Although the North American market is relatively small at present, it is expected to grow at a compound annual growth rate of 65.93% during the period 2024-2030. This growth is mainly driven by policy promotion and the construction of charging infrastructure, especially the rapid development of charging networks driven by companies such as Tesla.
4. Standardized development of the European market
Europe attaches great importance to standardization and interoperability in the construction of electric vehicle charging infrastructure. With the strong promotion of the EU's renewable energy and emission reduction targets, the research and development and market demand of charging modules are also accelerating. It is expected that by 2030, the European market will become an important competitor for global charging modules.
Conclusion
The global development trend of electric vehicle charging modules shows the dual drive of technological progress and market demand. In the future, with the high power and intelligence of charging modules and the continuous expansion of the market, the charging infrastructure will be more perfect, promoting the popularization and development of new energy vehicles.
