The proposed fast charging scheme increases battery life by managing the charging based on the battery’s state of health, state of charge, and the open-circuit voltage predicted in real-time. This is compared with the conventional CC–CV charging scheme.
Natural current absorption-based charging can drive next generation fast charging. Natural current can help future of fast charging electric vehicle (EV) batteries. The fast charging of Lithium-Ion Batteries (LIBs) is an active ongoing area of research over three decades in industry and academics.
The proposed fast charging scheme can increase the battery’s lifetime compared with the conventional CC–CV charging scheme. This is because the charging is managed based on the battery’s state of health, state of charge, and the open-circuit voltage predicted in real-time.
However, fast charging of energy-dense batteries (more than 250 Wh kg −1 or higher than 4 mAh cm −2) remains a great challenge. Ten-minute fast charging enables downsizing of EV batteries for both affordability and sustainability, without causing range anxiety.
In a Battery Electric Vehicle (BEV), the battery with a fast charge transfer rate is used for charging, while the slow battery powers the vehicle. Depending on the situation, the fast-charging battery can pump charge into or out of the slow battery while not in contact with another BEV.
Battery fast charging must be evaluated by three metrics simultaneously: (1) charge time, (2) specific energy acquired, and (3) cycle number under the fast charge condition. Lack of any of the three numbers is inadequate or misleading.

Discovery may lead to longer-lasting, longer-range EV batteries
Rechargeable batteries lose stored energy when they''re not being used because an idle battery undergoes internal chemical reactions that slowly drain its energy. This "self-discharge" process can eventually consume active ingredients in the cathode, where the electron-spent lithium ions collect while the device is in use. This shortens a battery''s life …

3 · For example, a new battery in good condition will charge more quickly than an older, worn battery. Consider a common situation: if a driver accidentally leaves their lights on overnight and comes back to a dead battery, starting the car and idling it for at least 30 minutes will typically restore enough charge to start the engine the next time.
