Keynote Speech Script

Hello everyone, I’m Tin founder and CEO of Open Energy

Today I’m gonna talk about the most revolutionary and affordable solution for EV Battery Swap that can change forever how billions of people and goods will move using sustainable energy.

There are a lot of questions related to this technology that we will reply: the most common are:

  1. Is Battery Swap better than Fast Charging?
  2. Who can benefit from this technology?
  3. Isn’t it so expensive?
  4. how can you swap different battery packs?

Is the EV battery swap a new technology?

  1. No, the concept of an exchangeable battery service was proposed as early as 1896
  2. The first commercial application was offered between 1910 and 1924, by GVC (partly owned by General Electric), serving electric trucks. The vehicle owner purchased the vehicle, without a battery, the power was purchased from another company in the form of an exchangeable battery. Both vehicles and batteries were designed to facilitate a fast exchange. The owner paid a variable per-mile charge and a monthly service fee to cover truck maintenance and storage. These vehicles covered more than 6 million miles, almost 10M Km
  3. This is a video of a taxi fleet operating in 1943 in Spain with a very manual battery swap. Spain was punished by the Civil War (1936-1939) and the consequent restriction of gasoline, several companies dedicated to transforming passenger cars and vans into electric cars
  4. in the early 1970s there was the global oil crisis, which set many automakers to work looking for alternatives to gasoline power, both VW & Mercedes started the produce electric version of their mini-bus & mini-van, with a swappable battery
  5. As you can see clearly what is very interesting here is that those applications are related to commercial fleets
  6. Fast forward to recent times, 2007, we have Better Place that unfortunately, despite a great fundraising, marketing, and great partnerships, went bankrupt in 2013
    1. with an expected cost of 500K per station, it ended up costing 2M dollars
    2. and technical problems (video of the YouTube girl trying Better Place)
  7. in 2013 Tesla proposed their solution but and unfortunately the 200 private consumers invited weren’t that interested, and shutdown in 2015
  8. But today NIO changed the game and it is worth mentioning that
    1. is targeting the private consumers
    2. it turned out to be a great commercial strategy because the final consumer can avoid paying about 10,000 USD for the expensive battery pack in the first place, and rent it with an affordable pricing
    3. and China is the N.1 country for EV: sales & infrastructure
    4. They actually achieved more than half a million cumulative swaps in 2 years

unfortunately, those 3 recent solutions come with a big price tag, all are above a 1 million USD, and you can imagine why those solutions are not very scalable, especially considering that private consumers can charge their EV at home like an iPhone

1: Isn’t it too expensive? Definitely yes, but we will give you more details later

Who can benefit from the Battery Swap technology

  1. private user: can pay only the vehicle and rent the battery, NO MONEY, NO HASSLES. But while most of the private owners have their vehicles idle for more than 90% of the time, fleet operators have multiple drivers, multiple shifts, getting close to 24/7 operational times.
  2. the truth is that while we are working from home, or our office, eating or sleeping, billions of goods and people are moving 24/7, again, with drivers doing multiple shifts
  • QUESTION: how can you move 21B goods in 24/7 using Logistics EV?

To understand this we talked to some of the biggest fleet operators in the World. Those companies care mainly about 2 things: money and time

  1. Money to be more precise is related to the TCO the total cost of ownership which means you buy the vehicle maintenance repair everything that you can see here
  2. TIME, precisely operational time how can I leverage my assets (commercial vehicles) to operate as much as possible, ideally no stop 24/7 with multiple drivers, multiple shifts?

Both are connected:

  • Money: the battery pack is the most expensive component or asset of the fleet, and it’s also the easiest to degrade
  • Time: it’s a trade-off. If you want to operate more hours you need to use fast charging every day, and this is reducing the lifespan of the battery up to 3 times less compared to charging it at the right temperature and speed

Fast charging every day your battery is literally killing rapidly the chemistry inside your cells

obviously for high mileage fleets, Battery Swap can give you:

  1. more time: full capacity in a few minutes
  2. more money value:
    1. your most expensive asset can be charged at the right speed and temperature, extending the lifespan up to 3 times more!
    2. you can charge when it’s cheaper, sometimes the delta between the highest and lowest peak can reach more than 50%
    3. your fleet can run 24/7 NO STOP generating more value

In this case: Battery Swap better than Fast Charging (ANSWER) for this type of application

But unfortunately, we have another problem: Amazon is moving billions of goods, and Uber billions of people

Obviously, they’re using different vehicles.

3: how can you handle different EV models or even better different battery packs?

The last 3 players that I mentioned can only handle one battery pack size

If you have a taxi you need to build a battery swap infrastructure for that

If you introduce a mini-van then you have to double the infrastructure cost

If you add a mini truck, triple. Are you following me? It’s definitely NOT scalable

some companies including us tried the modular batteries approach, which means dividing the battery pack in smaller modules.

It’s technically possible and kind of easier, but unfortunately, it’s not very feasible if you really care about the cost:

  • not the cost of the station
  • it’s the cost of the battery pack, because unfortunately for each module you need to multiply the number of connectors and other expensive components
  • The result is a higher cost of the entire battery pack, which is already pretty expensive

How can we solve all of this?

1: why Battery Swap Stations are SOOOOO expensive?

2: how can those fleets take advantage of an electric power train running 24/7 never stop?

3: how can you handle different EV models or even better different battery packs?


1: why Battery Swap Stations are SOOOOO expensive? How can we fix the cost of the stations?

2 main things are usually over-engineered:

  • the lock and unlock system
  • the alignment system

Some solutions are lifting the entire EV, we’re talking about 5000 pounds or 2.4 tons (EV + Battery), which is not very precise.

So you need to use expensive robots to fix this to align the whole system, to replace the battery.

Durability & reliability problems: in fact some are using screws for the unlocking and locking of the battery, which is not a very optimal

We started asking ourselves:

  • how can we fix the unlock and lock system and the alignment system that is making the stations so expensive?

We thought outside the box, looking for solutions in other industries

We look back at our experience not only in normal cars but also in the other extreme sectors such as racing like Formula One or aerospace

We found out in those applications we have very advanced locking/unlocking systems that are VERY reliable and NOT that expensive

As well as the alignment system!

We came out with an adapted solution that is several times more stable and durable, that can handle flawlessly massive amounts of swaps very stable, and it’s very affordable.

So affordable that we can bring down the costs several times as you can see here.

3: how can you handle different EV models or even better different battery packs?

We found out that the modular battery is raising the cost

in the end, we engineered our station and it’s going to be the first Multi-standard battery swap station we use the same technology for one battery pack standard and we leverage about 80% of the parts to handle more standards

Who else can benefit from Battery Swap Stations? Energy companies

We asked ourselves how we can make these stations with the lowest impact on the infrastructure, and make it sexy for Energy Companies

  • we engineered an ultra-affordable station that can handle multiple battery packs
  • but also a very compact solution because we can house the entire system into a 20 feet container
  • that can be even mobile easy to transport and easy to replace
  • so we can lower dramatically also the cost and maintenance time by just replacing the station in without interrupting the service
  • other solutions need to send technicians on a site for several hours to fix the problem
  • we can just plug and play replace it, so full operation time
  • What else can we do?
  • Energy companies can recharge the batteries at the lowest cost possible, leverage renewable sources
  • Ensure that the Battery is charged at the optimal condition: right temperature and speed, making the lifespan 3 times longer compared to fast charging
  • and we can leverage the batteries in a station for pick shaving of the electrician electricity grid, making profit

How to adapt our technology to existing EVs?

  • We created a system to upgrade EV with a minimum intervention that is not disrupting the assembly or manufacturing lines
  • Plus we are also making advanced EV platforms with the Battery Swap technology seamlessly integrated, that’s ideal for new EV projects

From this quick comparison you can see now how we made the most effective advanced and affordable battery swap solution and here’s the video.

So, that’s the HyperSwap! We hope you liked our technology and speech.

It’s going to be ready very soon for the first demonstration

To recap HyperSwap is a battery swap technology that can revolutionize the efficiency and affordability of taxi, commercial, and even private vehicles.
