Powerswap
Background

The sales and introduction of electric vehicles (EVs) evolves very slowly. In Sweden 2017 only 0,4 % of the new vehicles purchased were represented by EV’s.

Why?

The reason is that the EV can’t be used in the same way as a fossil car due to long charging times and limited access to charging spots.

The
Concept

Powerswap has developed a fully automatic battery swap system for electric vehicles. With the Powerswap system you can “refuel” your electric vehicle in 3 minutes. The whole procedure is done in Drive-Thru style and the driver can remain inside the vehicle while the empty battery is being replaced.

Furthermore, the battery swapping machines, unlike our competitors, are small and can be placed on existing refueling stations or parking lots at a very low cost.

Advantages

  • The battery is swapped faster than fueling a petrol car
  • EV's can be sold without the battery (lease) and will become less expensive to buy than a petrol car
  • Less stress on the grid and the batteries as more time can be used for charging
  • The car is not blocked from usage during the charging
  • Refuelling is made in automatic Drive-Thru fashion
  • An infrastructure can be established faster and at a 1/10 cost compared to a huge number of public charging poles

Battery charging
require time...

Battery charging require time. Even quick charging often requires as much as 2 hours. One might expect that the future developments will bring the charging time to zero, but this will never happen due to the laws of nature.

As an example, the current needed to charge three Tesla batteries in the same time as filling up a petrol car (3 min) is 7300 Amps! Compare this to the 16 amps which are the common current delivered to residents. In a future large scale scenario one can see that the challenges are extreme.

The Game
Changer

By eliminating the remaining problems with long charging times, Powerswap will boost the large scale market expansion of electric vehicles. The project is a major undertaking, but we have found a way to start small and grow.

The solution is based on installing swap units at existing fuel stations or parking lots, not to build new swap stations which have been tested by other players before.
