Will the electric car automatically cut off power when fully charged?

[DeJade]

Electric cars do not automatically disconnect when fully charged, but the charging device has protective settings that automatically cut off the main charging device after full charge and enter a float charging state. That is, a small current is used to continue charging the battery, which is then called float charging, also known as trickle charging. The purpose of float charging has three aspects: Extend lifespan: Maintain the battery voltage within the float charging voltage range, where the corrosion of the battery's grid (the conductive skeleton of the electrode plate) is at its slowest, thus extending the battery's lifespan. Compensate for self-discharge loss: Replenish the capacity loss caused by the battery's self-discharge to keep the power sufficient. Inhibit sulfation: Suppress the sulfation caused by the recrystallization of active materials.
