China’s EV ultrafast charging stations: Challenges, solutions, and costs
2025-04-29
(Press-News.org)
A new study published in Engineering delves into the future of ultrafast charging stations for electric vehicles (EVs) in China, exploring charging patterns, grid impacts, solutions, and upgrade costs. As the global EV market continues to expand rapidly, with China leading the way in EV adoption, understanding these aspects is crucial for sustainable development.
The research team, led by Yang Zhao, Xinyu Chen and Michael B. McElroy, analyzed real-world charging data from over 15,000 EVs at fast-charging stations across ten districts in Beijing. They established scenarios for current and future EV specifications and charging parameters, considering factors such as charging power, battery energy, and charging times.
One of the key findings is related to the impact of increased EV charging power on station loads. Contrary to the common assumption that doubling charging power would double the station load, the study shows that this is not the case. Larger stations with more chargers experience a relatively modest peak power increase of less than 30% when fast-charging power is doubled. This is because shorter charging sessions are less likely to overlap. For example, in the simulations, as the maximum EV charging power increased tenfold from scenarios S1 to S7, the peak load at the airport charging station increased by only a factor of 4.90.
The researchers also investigated two generalized solutions to address the issue of insufficient power capacity at charging stations: a dynamic waiting strategy and the deployment of energy storage. The dynamic waiting strategy can effectively decrease peak loads by delaying some charging sessions. For instance, at the airport EV charging station, with a total power capacity of 120 kW times the charger number, it can satisfy ultrafast charging demands from S1 to S7 using only this strategy, with a reasonable increase in waiting times.
Regarding energy storage, it can buffer peak loads, but the cost is a major consideration. The unit cost of lithium-ion battery energy storage is approximately 4 times higher than that of pad-mounted distribution transformers in China. However, energy storage has its advantages, such as not requiring grid capacity expansion and enabling more flexible installation.
When it comes to upgrade costs, the study identified chargers and distribution transformers as the main expenses. Comparing different upgrade strategies, the research provides valuable insights for policymakers and industry players. The results suggest that deploying large ultrafast charging stations with chargers between 350–550 kW in high-demand regions could be a viable solution to meet the surging charging demands of EVs in China. This research offers a comprehensive understanding of the future of EV ultrafast charging stations in China, which will contribute to more informed decision-making in charging infrastructure planning and grid management.

A new study published in Engineering presents an innovative approach to building energy management that combines quantum computing with model predictive control (MPC), aiming to enhance energy efficiency and drive decarbonization in buildings.
Buildings are major energy consumers, contributing significantly to global energy use and greenhouse gas emissions. To address these issues, researchers Akshay Ajagekar and Fengqi You from Cornell University developed an adaptive quantum approximate optimization-based MPC strategy. This strategy is designed for buildings equipped with battery energy storage and renewable energy generation systems, such as photovoltaic (PV) panels.

SCOTTSDALE, Ariz. — April 29, 2025 — HonorHealth Research Institute recently treated the first patient in a 50-site international clinical trial that will test a new type of therapy aimed at difficult-to-treat melanoma, an aggressive type of skin cancer.
This new therapy targets PRAME, a peptide commonly found in melanoma tumors. The therapy uses the patient’s own manufactured and enhanced immune system T cells to create billions of new patient specific cells to attack melanoma, even after the cancer has spread to other parts of the body.
“We are excited about the potential of this new type of cellular therapy,” said Justin Moser, M.D., an associate ...

WASHINGTON, April 29, 2025 – The beloved Italian pasta cacio e pepe is perhaps best known for two things: being delicious and being frustratingly difficult to cook. At first glance, it looks like a simple recipe, containing only three ingredients: pasta, pecorino romano cheese, and black pepper. But as anyone who has tried to make it will know, the cheese will often clump when added to the hot pasta water, turning what is supposed to be a smooth, creamy sauce into a stringy, sticky mess.

About The Study: Semaglutide and tirzepatide prescriptions within Epic-affiliated health care systems increased slightly between 2021 and 2024, but their uptake remained limited, with only 3% of eligible patients having ever received a prescription during that period. Furthermore, there were disparities in prescribing of varying magnitude based on race and ethnicity, social vulnerability, and urbanicity, although the absolute differences were small compared with the overall underutilization.
