Fast Charging refers to the technology of charging electricity into the battery at a rate far higher than that of conventional charging, which can usually charge the battery to about 80% within 30 minutes. This technology is widely used in electric vehicles (EV) and energy storage systems to improve charging efficiency and shorten the waiting time for users.
The impact of rapid charging on batteries:
Advantages:
– Significantly reduces recharging time, enhancing user experience
– Supports high-frequency usage scenarios (such as taxi services, shared travel, logistics distribution)
Challenges:
– Easily causes battery temperature rise and material stress
– Accelerates battery aging (especially under high temperature or high SOC charging)
– May produce side reactions such as lithium dendrites and SEI film damage
