Chongqing Leads the Way in Battery Swap Infrastructure

A significant milestone in electric vehicle (EV) infrastructure has been achieved in Chongqing, as the city becomes the pioneer in deploying CATL's innovative battery exchange stations compatible with the Choco-SEB system. Currently hosting 34 such stations, the number is projected to increase to 50 by year’s end. These stations are equipped to hold up to 30 batteries each, ready for swift exchanges that take under two minutes—a stark improvement over Nio’s existing three-minute swap process. This advancement underscores a pivotal shift in EV convenience and efficiency.
The Changan Oshan 520, an electrified version of the traditional combustion-engine Eado sedan, exemplifies this progress. Measuring 4.77 meters in length, 1.84 meters in width, and 1.47 meters in height, the midsize sedan boasts an electric motor producing 105 kW of power. The model designation hints at its range capabilities, achieving 515 kilometers under China's CLTC standard testing. With over 15,000 corporate orders already placed, the Oshan 520 not only demonstrates market appeal but also highlights the growing demand for efficient EV solutions.
Innovative strides continue as CATL introduces standardized battery packs within its Choco SEB framework. Known for their resemblance to chocolate bars, these Swapping Electric Blocks were first unveiled in 2022 under the Evogo initiative. The December presentation revealed two fixed sizes: the 20# for compact cars with a wheelbase ranging from 2.20 to 2.30 meters, and the 25# for larger vehicles with a wheelbase extending up to 2.90 meters. Utilizing LFP technology, the 25# pack provides 56 kWh of energy content, chosen for deployment in Chongqing. Looking ahead, CATL aims to establish 1,000 battery exchange stations nationwide by 2025, complemented by partner-operated facilities. This expansion will cater to both passenger cars and commercial trucks, reinforcing a sustainable future through comprehensive EV support systems.
As cities embrace advanced technologies like CATL's Choco-SEB system, they pave the way for a more sustainable transportation landscape. Such innovations not only enhance urban mobility but also contribute to global environmental goals by reducing reliance on fossil fuels. The collaboration between automotive manufacturers and infrastructure providers signifies a promising era where technological advancements meet practical solutions, fostering a cleaner and more efficient world.
