A quick battery swap moves the charging wait elsewhere

A battery swap lets a compatible car leave with an already charged pack while the depleted pack stays behind. NIO's 2024 system description shows how some waiting and preparation move from the driver to a station managing a stock of batteries.

Questions you could explore

  • What would happen to waiting times if cars arrived faster than charged packs became available?
  • How do spare-pack inventory and off-vehicle charging capacity affect a battery-swap station's throughput?

How can a heat pump deliver more heat than its electricity input?

Energy4–5 minA heating device seems to promise something impossible when its heat output exceeds the electricity it uses. A heat pump's energy account includes another input: heat moved from its surroundings.

A solar cell's route from light to electricity

Shining sunlight onto a piece of silicon is only the first step in making solar power. When incoming photons knock electrons loose inside the semiconductor, an internal electric field built into the solar cell's layers must separate those charges and guide them into an external circuit before they simply recombine.

How does a wind turbine turn moving air into electricity?

Energy3–5 minA turbine's blades are only the visible beginning of the journey from wind to electricity. Their rotation drives a generator, though the machinery connecting those parts differs between turbine designs.
