NINGDE, China – On January 18, Contemporary Amperex Energy Service Technology Ltd. (CAES), a wholly-owned subsidiary of Contemporary Amperex Technology Co. Ltd. (CATL), rolled out its battery swap solution EVOGO featuring modular battery swapping at its first online launch event. Comprised of battery blocks, fast battery swap stations and an app, EVOGO will be first launched in ten cities, said Chen Weifeng, general manager of CAES.
Innovative Modular Battery Swap Solution Injects New Life into Market
To solve the problems of range anxiety, inconvenience of refueling, and high total cost of ownership, CAES rolled out its innovative modular battery swap solution on Tuesday’s online launch event. Based on the separation of vehicle and battery, CAES considers the battery as a shared product, creating a whole new experience for the market.
Designed to look like a bar of chocolate, “Choco-SEB (swapping electric block)” is a mass-produced battery specially developed for EV battery-sharing. It boasts the advantages of high-energy density with small size, flexible combination and minimalist design.
With the support of the latest CTP (cell to pack) technology, 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 200 km.
Meanwhile, the Choco-SEB is compatible with 80 percent of global BEV platform-based vehicle models available on the market, and all BEV platform-based models to be released in the next three years globally. Customers are free to take one to three blocks to meet different range requirements at swap stations.
Furthermore, equipped with wireless BMS technology, the trailblazing Choco-SEB does not have any parts on its exterior except the high-voltage positive and negative terminals, which significantly increases the reliability of plugs.
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.
The app links customers with different modules of EVOGO, allowing the connection among customers, vehicles, stations and batteries, and provides other services as well.
High Compatibility, Need-Based Battery Rental, and Complementarity with Charging Services
Unlike conventional battery swap solutions, EVOGO has achieved two innovative modes of compatibility. Choco-SEB is designed to suit vehicles ranging from Class-A00, Class-B, and Class-C passenger cars to logistics vehicles. At the same time, the swap stations can match all vehicle models by different OEMs that use Choco-SEBs, allowing a free choice of vehicle models for battery swaps.
In fact, most car owners tend to purchase EVs of higher power capacity in order to alleviate range anxiety, although only 10 to 20 percent of the total capacity is usually needed for daily use. They have paid a high sunk cost for a power capacity that is rarely needed.
To address the pain point, EVOGO allows customers to choose the number of battery blocks to rent according to their driving scenarios and habits. Only one block is needed for inner city commuting, while for longer trips, customers can rent two to three blocks and swap them with one block after returning to the city.
Vehicles carrying Choco-SEBs supports both charging and battery swapping for power refueling. Together with the existing household charging and fast charging, EVOGO helps provide all-scenario power refueling solution.
