Technical FAQs 4

What are the real-world charging characteristics of fast-charging stations in China?

Real-world charging characteristics of five representative fast-charging stations in China: (a–d) residential zone; (e–h) commercial zone; (i–l) shopping center; (m–p) industrial zone; and (q–t) airport. For load and NOC profiles, the daily curves of 30 days are presented. The maximum NOCs are 4, 9, 9, 8, and 24 for the 5 sites (top to bottom).

How long does a fast-charging station take to charge a battery?

For fast-charging stations with around 9 chargers (average 120 kW per charger), the average waiting time for scenario S4 (charging power of 350–550 kW, battery energy of 120–150 kW·h) is less than 1 minute, and the maximum waiting time is less than 20 minutes.

How many charging stations are there in China?

To date, CAMS operates over 13,000 charging terminals in 213 cities across China. Through this partnership, Volkswagen and Xpeng will also explore the development of co-branded ultra-fast charging stations, further accelerating the expansion of the charging network and enhancing collaboration efficiency in charging infrastructure development.

How much does a public charging station cost in China?

A study in 2019 indicated that in China, the initial investment for a public charging station with 30 60-kW DC fast chargers amounted to approximately 0.3 million USD.
