Regenerative braking
When you lift off the accelerator or brake, the motor runs in reverse and returns energy to the battery instead of throwing it away as heat. It recovers part of what you spent, especially in the city.
In a combustion car, braking dumps all the motion's energy as heat in the discs. An EV does something smarter: as it slows, the motor becomes a generator and turns part of that motion back into electricity, which flows to the battery.
That's why city range often beats highway range: the stop-and-go of the city feeds regeneration, while the steady speed of the highway gives it nothing to recover. Many EVs — several Chinese ones included — let you tune its strength, to the point of driving almost with a single pedal.
