8. Huawei Hongmeng Intelligent Driving
Representative models: Wenjie M9, Zhijie S7
Technical highlights: Megawatt charging products (1.5 MW), plans to achieve a single-gun 3 MW charging rate, and adapt to high-voltage platform models.
9. Chery Automobile
Representative models: Xingjiyuan ES, Tiggo 8 New Energy
Technical highlights: high-density batteries (such as CATL Kirin batteries), charging for 10 minutes and a range of 300 kilometers (800V architecture).
10. Changan Automobile
Representative models: Deep Blue SL03, Avita 11. Technical highlights: full-domain 800V platform, charging for 10 minutes to replenish 400 kilometers, and adapt to 750V super charging piles.
2. The relationship between charging time and battery life
1. Differences in fast charging technology
Megawatt flash charging (such as BYD, Geely): 5 minutes to charge 400 kilometers, requiring a 1000V high-voltage platform and liquid-cooled charging piles.
Mainstream fast charging (800V architecture): 15-30 minutes to charge to 80%, such as Xiaopeng and GAC Aion.
Ordinary fast charging (400V architecture): 30-60 minutes to fully charge, such as Tesla V3 supercharger.
2. Battery capacity impact
The battery capacity of 400 km range models is mostly 60-100kWh, for example:
BYD e6 (82kWh): Fully charged requires about 98 kWh (including loss).
Tesla Model Y (75kWh): Fast charging to 80% takes 30 minutes.
3. Actual charging efficiency
Environmental factors: Charging efficiency decreases by 20%-30% at low temperatures.
Grid restrictions: Supercharging piles may reduce charging speed during peak hours due to grid load current limiting.
III. Future trends
1. Popularization of supercharging: 2025 will become the “first year of flash charging”, and BYD, Huawei and others plan to build more than 4,000 megawatt-level supercharging stations.
2. Battery technology breakthrough: Cooperate with Tianyi and other companies to develop SPEED batteries that can charge 400 kilometers in 8 minutes, with the goal of mass production in 2025.
3. Battery replacement mode: Weilai and CATL promote the standardization of battery replacement, and complete battery replacement in 5 minutes.
Chinese new energy vehicle companies have greatly shortened the charging time through three major directions: high-voltage platform, liquid cooling technology, and megawatt-level charging piles. At present, the leading brands have achieved 400 kilometers of charging in 5-15 minutes, but popularization depends on the construction of supercharging networks and battery cost optimization. When choosing, users can give priority to models that support 800V architecture and liquid-cooled supercharging (such as BYD Han L and Tang L).
