New energy vehicles need to be charged for energy replenishment, typically taking anywhere from 30 minutes to several hours. Generally, new energy vehicles support both fast charging and slow charging. Fast charging typically refers to high-power direct current (DC) charging. Given the current technology, after a certain period of fast charging, the charging current must be reduced to protect the battery, transitioning into slow charging. The percentage of fast charging indicates the proportion of battery capacity replenished using a fast-charging station before transitioning from fast charging to slow charging relative to the battery's total capacity.
