Battery swapping — exchanging the pack instead of charging it

Battery swapping replaces charging with an exchange. The car enters an automated station, the depleted pack is lowered out from underneath, and a charged pack is fitted in its place. The depleted pack is then charged at the station, at its own pace, while the driver is already back on the road.

How a swap differs from charging

A charging session is something you do to your own battery. A swap is a service: you hand back one pack and receive another. That changes what the battery is.

• The pack is shared. It belongs to a pool circulating through the station network, not permanently to your car. Your car must be built so the pack can be released from below, which is a different design from a pack that is bolted or integrated into the body (see cell-to-body).
• The battery can be a subscription. Some makers sell the car with or without the pack and charge for the battery separately, often called battery-as-a-service (BaaS). The purchase price drops, and the long-term wear of the pack stops being the owner’s problem. See degradation and battery warranty.
• The station is the product. A swap-capable car without a reachable station is an ordinary electric car carrying hardware it cannot use.

Which Chinese brands use it

NIO is the brand built around it: its cars are designed for automated swaps and it operates its own station network, described in the NIO brand article. NIO models in this registry, such as the NIO ET5, can have the pack exchanged at a station, so battery capacity is not permanently tied to one individual car.

Geely group has also backed swapping, with networks aimed mainly at the Chinese market, and in September 2026 Geely Holding agreed to take a minority stake in NIO Power, NIO’s swap and charging unit, subject to regulatory approval (NIO filing, September 2026). We do not treat that as a statement about any Geely-group brand in Europe. The Lynk & Co subscription bundles swap options, but we have no confirmed official source that these mean battery swapping on Lynk & Co cars in Europe, so we do not claim it.

Swap networks in China are built by several players with different, partly incompatible pack standards. That is a reason to expect a network to serve only the cars designed for it.

Swapping in Europe: what a buyer can rely on

NIO has stated that it operates swap stations in Europe, and its own news releases describe them as an expanding network in countries including Norway, Sweden, Denmark, Germany and the Netherlands (NIO statement, 2024). That is a dated claim from the manufacturer, not a promise for your road. Whether a swap is usable for you depends on three local facts: where the stations are relative to your regular journeys, whether the importer sells the battery-subscription option in your country, and what the subscription costs in your currency. Those belong on a market page with a source and a date, not in a glossary entry. Do not assume a station exists in a country because NIO sells cars there.

No other Chinese brand in this registry offers swapping to European buyers that we can confirm from an official source.

Trade-offs against fast charging

• Time. A swap is quick and predictable, while a charging curve slows as the battery fills. Fast charging is, however, available at far more locations, because it needs only a charger and not a dedicated station.
• Infrastructure. Stations are expensive capital that has to be built before the first customer benefits, so coverage is thin outside a few corridors. A CCS2 socket (see CCS2) works at any compatible charger, and the NIO ET5 has one as well, so a swap is an option rather than a necessity.
• Battery health. A swapped-in pack has an unknown history but a manufacturer behind it, which removes the owner’s exposure to degradation when the pack is subscribed to rather than owned. A standard owned pack leaves that risk, and its residual value, with you.
• Lock-in. Swapping ties you to one network and one pack design. If the maker withdraws from your market, the car loses a feature and the subscription loses its meaning.
