There are already electric vehicle models on the Chinese market whose traction batteries can replenish the charge from 0 to 80% in 15 minutes or a little more, so the relevance of developing a network of high-speed charging stations is increasing. By the end of this year, Huawei plans to install 100,000 charging stations in China, allowing them to replenish 1 km of power reserve in a second. They will charge the average electric car in 8 minutes.
As explained Nikkei Asian Review, when calculating the charging time in this case, the average capacity of the traction battery is 80 kWh and favorable weather conditions, such as fairly warm weather, since preparing the battery for charging in cold weather increases the duration of the process. In China, as of the end of November, there were more than 11,000 Tesla Supercharger charging stations, but their maximum power in this country does not exceed 250 kW, so under the same initial conditions, it takes almost 20 minutes to charge an electric vehicle battery of the specified capacity.
Huawei provides its high-speed charging stations with a power of 600 kW and a liquid cooling system. The company claims that its many years of experience in creating base stations for communication networks allows it to develop charging stations that are resistant to any atmospheric and weather conditions. Huawei is not the only company offering charging stations of comparable power in China. In August, for example, XPeng began installing several hundred 480 kW charging stations.
It is important that Huawei charging stations will allow owners of electric vehicles of any brand to connect to them, while Tesla charging stations in China allow this to be done only in 20% of cases. However, among the charging stations installed by Huawei and its partners there will also be less powerful modifications, designed for a maximum of 250 kW. For now, Huawei is going to limit its core activities in the Chinese market, but if there is demand, it is ready to expand beyond China.
