CATL rolls out one-minute EV battery swapping resolution, total enterprise round it


Battery swapping, as soon as thought of an answer that had been outmoded by the potential for quicker road-trip charging, is again—with the world’s largest battery provider CATL onboard and launching a whole enterprise round it.

That enterprise, referred to as Evogo, makes loads of sense proper now that the longtime discount in battery cell value has reversed course, largely as a consequence of provide constraints. Most EV homeowners have a tendency to purchase the automobile with the larger battery in order to get rid of vary anxiousness, when solely 10-20% of the overall capability of the battery is required for day by day use. “They’ve paid a excessive sunk value for an influence capability that’s not often wanted,” the corporate sums. 

In phrases that clients, automakers, and regulators will all like, it’s a scheme that can permit lower-priced EVs, and extra of them. 

Evogo, will revolve round “an modern modular battery swap resolution” that makes use of standardized battery blocks and has “excessive compatibility with automobile fashions.”

That takes the type of a brand new bar-like battery—nicknamed Choco-SEB and designed across the concept of battery sharing, supporting cell-to-pack know-how and an power density of greater than 160 watt-hours per kg, with a volumetric power density of 325 Wh/L. 

CATL says every 26.5-kwh block can allow a driving vary of about 200 km (124 miles). And the thought is that you could be solely want considered one of these blocks for day by day commuting, whereas three of those will comprise a long-range battery, with clients at battery swaps doubtlessly swapping only one block or all three as wanted.Likewise, clients might doubtlessly lease one block with the automobile however lease further blocks as wanted for a protracted journey.

One of many greatest limitations for battery swapping at the moment is compatibility and the huge array of various cell codecs, packaging strategies, and cooling methods. However CATL says that the swapping system is suitable with “80% of worldwide BEV platform-based automobile fashions out there in the marketplace, and all BEV platform-based fashions to be launched within the subsequent three years globally.” That would come with Tesla, which established a battery swapping pilot program in 2014 and deserted the thought a short while later.

The brand new swapping-friendly pack comprises a wi-fi battery administration system (BMS), and has no elements on the outside of the pack aside from the high-voltage terminals. It’s suitable with current onboard chargers and residential charging.

Evogo’s swapping station will take up the house of about three parking areas, in response to the corporate, with 48 of the battery blocks in inventory and a swapping time of only one minute for a single block. The system is designed to be compatibility not simply with compact to midsize passenger automobiles but in addition with logistics and supply automobiles—so the swapping stations have been designed round this, too.

Nio is the one automaker that provides a major deal with battery swapping. Final 12 months it introduced plans to have 4,000 swapping stations globally by 2025, with its proprietary resolution providing a full long-range battery swap in about 5 minutes. Within the U.S., the Bay Space startup Ample claims to have a modular resolution that can be utilized on a variety of automobiles. It’s working with Uber to display the tech on a fleet of Nissan Leafs, that are air-cooled, but it surely’s unclear how the answer interfaces with completely different liquid-cooling techniques. 

For Evogo, an app will hyperlink clients with the swapping service in order to line a battery block up when en route. 

Initially, in response to the corporate, Evogo can be launched in 10 cities. Extra details about suitable fashions and platforms is coming quickly.
