remove the depleted batteries and replace them with new fully

charged ones. The whole process takes about 10 minutes. It's

called battery swapping. San Francisco-based Ample is

bringing the idea to the U.S. The company was in stealth mode

for seven years before launching recently with five swapping

The plan is to be available wherever people need a fast

The benefits of swapping over charging are numerous. When

you're fast charging, you are degrading the battery at a much

faster rate than if you slowly trickle charge a battery.

The concept is not new. Better Place launched an EV and battery

swapping company in Israel, but the company went bankrupt in

2013, even though it had almost $1 billion in funding. And Tesla

Took 90, sort of 90 seconds for a pack swap. So hopefully this

is what convinces people finally that electric cars are the

Battery swapping is already common in China. Electric

Vehicle maker Nio plans to double its network of swapping

stations to 500 this year, and plans to open battery swapping

stations in Norway as part of its expansion into Europe.

Geely, another Chinese automaker plans to build 200 swapping

Almost every taxi in Beijing that moved to electric is being

swapped. So there is a significant swapping happening

in China. We just don't know about it here because we haven't

yet had the problem of moving a very, very large fleet into

But these swapping stations are expensive, and it's unclear

whether American car owners would be willing to swap out

In America, if we're buying a car dammit, we want to buy the

We've really taken the EV battery pack and broken it down

But why now? And can battery swapping be a good charging

Nio, Tesla and Better Place all use the same technique. That is

removing the entire battery pack and swapping in a new one. The

batteries are usually then charged off site, but EV

batteries are massive. And this is part of the reason why

swapping stations have historically been so expensive.

You have challenges there. If you're connecting a 900 pound

thing, then you have to have really really robust electrical

connectors that can handle a few 100 volts and have some dropped

in and out dozens hundreds of times over the lifetime.

But Ample is trying a new technique. It is building its

own batteries designed in these Lego-like modules that charge

right inside the battery swapping station.

The main thing that sets Ample apart is that we have a modular

battery. With our modular batteries, we can take them out

a few at a time and they're very light, they're very easy to

maneuver, the station is the size of two parking spots, so it

doesn't require a lot of square footage since the batteries can

be individually put on a much smaller rack to charge.

I think part of thing about the modular batteries is it is

largely the ability to fit into different sizes. If it's a big

car, you can put in more a small car has less. So it solves a lot

more problems than we initially thought about by going through

We were not allowed to film the proprietary tech inside of the

charging station, but we were able to take a peek. Behind this

wall there are robots zooming around taking fully charged

battery modules off of shelves and then replacing them with

depleted batteries from the car. The new batteries are then

quickly but carefully screwed back into the car. And within

minutes the fully charged card drives out at the station. The

station is fully autonomous and the payment is done through the

app. Ample's Bay Area stations cost the driver about 10 cents

per mile for a swap which is less than gas in the area, but a

The car isn't, you know, perfectly centered where it

needs to be, the robots will move it to the right spot. So

there's it's very easy for anyone to just drive up and park

Ample battery stations are designed to be installed quickly

along high traffic routes. Former Tesla manager Lindsay

We build in our office here, what we call sub assemblies, we

build chunks, take them to the site, we create them up, ship

them over and then assemble on site so there's no construction,

How much does it cost to build one of these.

We can't give the exact number but I would say in a tens of

thousands of dollars. So effectively the equivalent of

maybe a slightly expensive level two charger.

One of the major benefits to ample swapping station is that

it does require a lot less power than our traditional plug in

This is because ample slowly charges the batteries and can

control when they are charging. This also helps ensure the

batteries are being charged with renewable sources, not fossil

The benefits of swapping over fast charging or that you can

charge when it makes sense for the grid. So when someone pulls

up to charge, they need to pull that energy from maybe not

always sustainable resources versus with swapping stations,
