Battery swapping is a method used in electric vehicles where a depleted battery is replaced with a fully charged one at a designated station. This process allows drivers to quickly continue their journey without waiting for their battery to recharge, making electric vehicles more convenient for long-distance travel. The battery swapping system is often implemented by companies like NIO and Gogoro, which have established networks of swapping stations. This approach can reduce the overall charging time significantly, as the entire process can take just a few minutes, similar to refueling a traditional gasoline vehicle.
