Requirements to the Mobility System

• • • • • • Good prices Fast fuel/battery refill Flexibility Regularity, punctuality Clarity Environmentally friendly

Requirements to the Mobility System

• • • • • Cheaper bus connections Short waiting times Less traffic jams No more use of fossil fuels  energies renewable Less noise

Our future system: Battery Swapping

Our future system: Battery Swapping

• • Exchangeable batteries  Battery switch stations Conveniently located charge spots  In cities: 3 km Outside of cities: 15-20 km Highways: 40 km

Comparison

Built-in Batteries

• Limited Range Takes a long time to charge • Price Expensive (can cost more than $10,000) • Capacity Lose their capacity over time  owner has to buy a new one  car loses its value • Upgrades Upgrades very expensive

Switchable Batteries

• Unlimited Range No charging  you get a fully charged battery • • Price Customers only pay for the energy capacity Car gets sold without the battery • Capacity Changing batteries • Upgrades Car-owner gets benefits without paying

Company Better Place

• • • • Network of electric car battery changing stations (Israel and Denmark) Wanted to spread this model around the world Went bankrupt the 26 th May 2013 but: idea still alive  e.g. Tesla(LA) http://www.youtube.com/watch?feature=play er_embedded&v=OHHvjsFm_88

The Better Place Concept

The Better Place Concept

The Better Place Concept

Advantages

• • • Cheaper for electric car owners  they do not have to buy their own batteries (- $10,000) Reduction of prices for electric cars Drivers do not have to leave the car during swapping process

Advantages

• • • • Takes less time than recharging the battery The entire process takes only 90 sec Do not have to pay for fuel  only for the electricity they use Unlimited driving range  network of battery switch stations

Disadvantages

• • • • Takes lots of time and money to build the whole system Battery swap stations: $500,000 each Every car: same size and configuration of battery pack "problematic for hotly competitive car manufacturers“  obstacle for future innovation

The Tesla Concept

• • • Fast battery swapping (90 sec.) Announcement June 2013: battery swapping station in each of the supercharging stations Owners can pick up their battery pack fully charged on the return trip, which is included in the swap fee

Plans for the Future

• Worldwide transport network – possible to change the “German” batteries in other countries  no more problems because of nonuniform charging couplers – Broken batteries can be exchanged everywhere – Uniform prices and contracts

Plans for the Future

• Not only for cars – Bus-swap stations at public places like the “Bushof” in Aachen – Different kinds of batteries for motorbikes, scooters or e-bikes
