US being left behind in EV charging speeds as China goes sub-5 min to 70%
Summary
China is leading in electric vehicle (EV) charging speed with new batteries that can recharge from 10% to 70% in around 4.5 minutes. In contrast, the fastest chargers in the United States currently provide much slower charging speeds, and U.S. EV models often do not accept the highest charging power available.Key Facts
- Geely in China has developed a battery that can charge from 10% to 70% in 4.5 minutes and from 10% to 98% in 8 minutes 40 seconds.
- This fast charging uses AI to manage battery temperature and improve battery life by 20%.
- Other Chinese companies like BYD and CATL are also offering fast-charging batteries with similar or better performance.
- In the United States, Tesla Superchargers mostly top out at 250 kW power, while other chargers range from 350 kW to 600 kW.
- Popular U.S. 800V EVs like Hyundai’s Ioniq 5 and Kia EV6 typically charge at about 240 kW, less than their maximum 800V capability.
- Heavy-duty electric vehicles in the U.S. can handle megawatt-level charging, but passenger EVs do not yet reach that level.
- ChargePoint is working on chargers capable of delivering over 1 megawatt by combining units, but standard connectors currently cannot handle that power.
- The U.S. EV charging infrastructure and vehicle charging speeds are behind China’s advancements.
