Is the age of the 10 minute fast charger coming

The US Department of Energy(DOE) has announced that it will spend $19M on battery support for electric cars to charge fast. It aims to reduce the cost of battery packs to less than $100 per kilowatt-hour by 2028, increase mileage to more than 300 miles, and reduce battery charging time to less than 15 minutes.

Among them, the 10-minute fast charging technology developed by the team of Wangzhaoyang of Pennsylvania State University won this plan and was officially adopted by the US Department of Energy.

It is understood that the Wangzhaoyang team has captured the 10-minute fast charging technology based on All-Climate-Battery(ACB) technology and successfully solved the key problems of lithium battery rapid charging and battery life. It is worth mentioning that the results of the study also achieved a rapid charging of 240Wh / kg power cells within 10 minutes and had more than 1,000 cycles, equivalent to a life span of 500,000 kilometers. This technology will become a battery product that supports 350kW fast charging stations.

As a brand new battery platform, the research results related to All-Climate-Battery(ACB) were published in the journal Nature in 2016. The battery can be operated at a low temperature of -50 °C. Fast charging, It not only solves the lithium precipitation problem of lithium batteries, but also increases the cooling ability of the core itself by 20 times. It is a new type of battery that is neither cold nor hot, and does not require an external heat management system.

In 2017, all-climate batteries were formally adopted by the Beijing Winter Olympics and became one of the core technologies for new energy transportation for the Winter Olympics environment. At the same time, BMW, Beiqi New Energy, Yutong passenger cars and other domestic and foreign car companies are also accelerating the application of this technology.
