Contemporary Amperex Technology Co. Ltd. (CATL), one of China’s fastest-growing companies, has rolled out a battery-swap service in its home market, allowing consumers to change batteries of electrically-chargeable vehicles (EVs) in one minute.

The company announced the news at a launch event, where it presented the new service under the name EVOGO. The modular battery-swap solution is made up of battery blocks, fast battery-swap stations, and an app. It will initially be rolled out in 10 cities across China, which keeps promoting infrastructure-related facilities such as charging and battery-swapping stations.

Battery-swapping is more prevalent in China than elsewhere in the world, with carmaker Nio planning to add an additional 100 battery-swapping stations to its network of 700 in the country by 2025. But the service is gaining traction elsewhere, with the manufacturer recently partnering with Shell to introduce battery-swapping stations in Europe in a pilot project from 2022.

Battery as a shared product

‘We consider the battery as a shared product, instead of a consumer product for personal use,’ said Chen Weifeng, general manager of CATL’s subsidiary Contemporary Amperex Energy Service Technology Ltd. He added that the new product would help EV drivers beat range anxiety while also getting rid of the ‘inconvenience’ to recharge batteries, as well as high purchasing and driving costs.

Its mass-produced battery, designed to look like a bar of chocolate, has especially been developed for EV battery-sharing. It can achieve a weight-energy density of over 160 Wh/kg and a volume energy density of 325 Wh/L, enabling a single block to provide a driving range of 200km.

CATL gives customers the opportunity to rent one to three blocks to meet different range requirements at swap stations. One block is typically sufficient for inner-city commuting, while the battery maker recommends two to three blocks for longer journeys.

The batteries are compatible with many battery-electric vehicles (BEVs) from different OEMs, suiting a range of vehicles, from Class-A00, Class-B, and Class-C passenger cars to logistics vehicles.

Compatibility and competition

‘The battery-swap station highlights high compatibility, need-based battery rental, and complementarity with charging services. With a footprint equivalent to three parking spaces, a standard EVOGO battery-swap station can house up to 48 Choco-SEBs and allows one-minute swapping for a single battery block, ensuring fully-charged batteries for customers at any time without a long wait. Moreover, EVOGO offers a variety of swap stations to suit the climates of different regions,’ CATL said.

The company launched 10 years ago and has quickly become a darling of investors, helping to give China a lead in EV batteries. It supplies batteries to most of the world’s carmakers, including Volkswagen, BMW, and Tesla. The New York Times found it holds one third of the global EV-battery market, with its biggest competitor being LG. Elsewhere, competition is heating up as carmakers keep pushing into the battery business by building their own batteries or investing in a range of companies to diversify the supply chain.

Last year, Geely, the parent company of Volvo Cars, announced plans to set up 5,000 battery-swapping stations globally by 2025. The company showcased the technology behind this service at the 2021 Wuzhen Internet Conference, with the process taking less than a minute. Tesla at one point explored battery swapping, but withdrew its plan to focus on its network of fast chargers instead.
