Why Do EVs Charge So Slowly?
When the battery is full, the ions are all gathered at the cathode. As the battery is slowly and steadily depleted with use, the ions pass from one side of the separator to the anode. When very few ions remain on the cathode side, the battery is low on charge. To recharge the battery, an electrical current is applied to the battery.
