ebuggy - TECHNICAL BACKGROUND

In technical terms, the ebuggy is a so-called on-demand range extender.  It will be hitched up to an electric car for long-distance travel.

How does it work

• Drive with the battery of your electric car in the city.
• Hitch up an ebuggy trailer at the first highway service station and drive with the electric energy of the ebuggy range extender.
• Return the ebuggy at a service station in your destination area.
• Drive with your electric car battery in your destination area.

External range extender

The ebuggy trailer is a range extender with a powerful Li-ion battery. The ebuggy works in the following modes:

• Working mode: the ebuggy replaces the traction battery of the electric car. The electric car battery is in stand-by mode.
• Recharge mode: The ebuggy is recharged at the service station.
• Smart grid mode: The ebuggy fleet works as a grid-integrated buffer power station.

The ebuggy is licensed for a travelling speed of 100 km/h.

Low-cost exchange stations

ebuggy has many advantages compared to other battery-changing concepts:

• Low-cost exchange stations
• No need for expensive automated robotics
• Standard recharge systems are sufficient
• Manual handling possible.

Very low capital expenditures (CAPEX) for the exchange stations enable a rollout by a franchise scheme. The ebuggy-trailer CAPEX can be refinanced by revenues from user fees within a short time frame.

Technology

ebuggy will be developed as an external range extender with a powerful lithium-ion battery for energy storage – focusing on a future with a purely electrical infrastructure. We are also studying alternative concepts, such as combustion engine generators or fuel cell generators. >> more
