Can You Unplug an Electric Vehicle Before It's Fully Charged?

[DeLorenzo]

Electric vehicles can be unplugged before fully charged. 1. EV batteries typically use lead-acid or lithium batteries, which have no memory effect and can be charged intermittently. 2. From a charging principle perspective, modern battery charging commonly employs staged charging - using constant current charging when battery levels are low. 3. When the charging voltage approaches the battery's termination voltage, it enters "trickle charging," a crucial phase for complete charging. 4. Therefore, prematurely stopping charging results in more superficial charge and reduced durability. 5. Under conditions avoiding over-discharge and over-charge, frequent charging and discharging helps maintain battery activity. 6. Electric vehicles, also called electric-drive vehicles, are categorized as AC or DC types. Typically, EVs use batteries as energy sources, converting electrical energy into mechanical motion through components like controllers and motors, with speed regulated by current control.
