Could Battery Swapping Make EVs More Sustainable?

Battery swapping was once thought of a rather niche service in the world of electric vehicles.

It’s a process that has been around in some form for many years: a driver takes their EV to a swapshop—a place not too dissimilar to a petrol station—where a team of attendants fit their car with a new fully charged battery.

Historically, though, there have been barriers to the scaling of battery swapping.

Firstly, barrier swapping stations are too few and far between to allay range anxiety.

Secondly, and perhaps most pertinently, there is little to no standardisation across the EV sector, meaning that the batteries in most cars are incompatible with others.

And then, of course, removing car parts is generally seen as a difficult and lengthy task.

However, it doesn’t take too much reflection to realise that these same barriers once blocked the road ahead for EV charging points, and for petrol stations before them.

But why are companies starting to take notice?

The benefits of battery swapping

After years of relative obscurity, battery swapping is starting to be considered a viable option for the sector going forward.

Quite simply this is because of the speed battery swapping offers. 

It allows drivers to cut downtime significantly; rather than waiting more than half an hour for an EV to charge, swapping only requires as much downtime as it takes to fill a car with petrol.

There’s also the effect that battery swapping can have on the overall lifespan of EVs.

Swapping allows batteries to be removed, refurbished and reused when they begin to degrade, meaning that owners aren’t tied to a degrading piece of technology that is expensive to replace. 

Unlike traditional internal combustion engine vehicles (ICEVs), electric vehicles often face massive depreciation when battery performance diminishes—typically after five to eight years of regular use.

There’s something of the circular economy about battery swapping: by removing batteries for centralised maintenance and refurbishment, companies can extend their usable life by up to 50% compared to fixed battery systems, reducing waste in the long term.

The market leaders in battery swapping right now

Chinese automaker NIO is at the forefront of battery swapping right now, having completed more than 30 million battery swaps across its network of more than 2,000 stations. 

NIO’s latest stations can complete a swap in under three minutes.

NIO's approach includes a Battery-as-a-Service (BaaS) model, allowing customers to purchase vehicles without batteries—reducing initial costs by approximately US$10,000—and subscribe to a battery service instead. 

This model has proven to be very successful when it comes to corporate fleets where minimising vehicle downtime is essential.

When it comes to motorbikes and scooters, Taiwan-based firm Gogoro has established some dominance in recent years. 

With more than 12,000 battery swap stations across Asia, Gogoro's network processes nearly 400,000 battery swaps daily. 

The company expanded into India in partnership with Hero MotoCorp with hopes of making inroads in the world's largest two-wheeler market.

And in the US, San Francisco-based start-up Ample has developed a modular battery swapping system compatible with several different vehicle models. 

The company has secured partnerships with ride-sharing services and delivery fleets, installing stations in urban centres where rapid turnaround is important for business.

The environmental and economic impacts of battery swapping

The environmental benefits of battery swapping go beyond increasing the lifespan of EVs. 

Centralised battery management allows for a far more efficient recycling process.

When parts come in and out of a designated location, material recovery rates can reach 90%. 

Naturally, this reduces the demand for mining critical minerals like lithium, cobalt and nickel, all of which are becoming increasingly scarce.

The economic upsides of battery swapping are plain to see too.

Fleet operators have reported that operational cost can be reduced by up to 25% compared to conventional charging solutions, primarily through decreased vehicle downtime and extended asset lifespans.

For personal EVs, a battery subscription service is far more manageable than the huge layouts required to purchase an EV outright, or to replace an obsolete battery.

With all that said, there are some obvious downsides to battery swapping as things stand. 

The lack of standardisation across manufacturers means that swapshops can’t fit every model with the same batteries. 

In the future, though, it is possible that regulations will force manufacturers to make all batteries compatible with other vehicles. 

And of course, the investments in worldwide swapshop infrastructure would be huge too.

Despite these hurdles, industry analysts project the global battery swapping market to reach US$852m by 2030, representing a compound annual growth rate of 22%. 

As automakers face increasing pressure to improve sustainability metrics, battery swapping technology stands poised to transform how we power and maintain the next generation of electric vehicles.
