Following links above, there is a 6/14/2011 interview with Mirko Hannemann, in german, at
Elektroauto: „500 Kilometer sind eigentlich kein Ding“ | Mobilität- Frankfurter Rundschau
The first part only is translated at
Electric Vehicles UK
Still no specifics about the battery, but some points from the interview:
- MH says they rejected an offer from Samsung for 600 Mill. Euro., saying they didn't want the technology to be blocked by being used in a specific area only.
- He financed development out of his own pocket (15 Million).
- Meanwhile, Daimler's head of research has invited him to participate in a national forum which advises the german government
- MH claims their battery is better than anything currently in use, regarding size, performance (or power), stability and reliability/strength under harsh conditions
- It would take about a year to get mass production "on its legs". (Apparently there are no definite plans yet.) This would be for a battery that allows building a car with 300 km (188 miles) range at a price no more expensive than a usual car.
--- the remaining points are from the not-yet-translated part ---
- The battery is definitely his (or their) own development.
- He studied a variety of subjects including applied physics, but didn't complete a degree as he started making money with various projects
- The interview mentions the fire destroying the berlin-record car is now known to have been arson, however there is no idea of who it could have been.
- a south german car manufacturer approached them, and they are going to deliver a black box a for examination of the battery's parameters, as a beginning.
- being asked whether the black box is guaranteed not to infringe on other's patents, he says they continued development where others have stopped, and that no one else would have know-how in their area
- that project is about racing, a good area to prove performance, operation under harsh conditions, and fast-charging abilities, for a new kind of series, the first car to be shown at IAA in September.
- they are getting a strong response from power - and grid companies, for using the battery for energy storage at the industrial level, and he says in that area much more money is to be made with the same storage capacity
- they have an opportunity to use their battery in the grid, and thinks they could install 300 MW next year. Mechanical systems would be too slow to respond to changes (switching time) in the grid in real time. Only battery technology could do this, They are currently building a 10 MW storage, claiming the largest battery storage in Europe.
