Battery swap technology has been around for a while. Nio, the Chinese EV brand, has recently passed three million battery swaps in China, and is to roll out 120 battery swap stations across mainland Europe in the next few years as it begins its European sales offensive. CATL, the Chinese battery giant, has also dabbled in various battery swap technologies for its Evogo car-sharing platform and also with lithium iron phosphate (LFP) battery swap tech for heavy-goods vehicles.
