Daimler Buses introduces Citaro hybrid bus; available on diesel and gas models; separate 48V network

Green Car Congress

The hybrid system’s disc­shaped motor with integral power electronics is a permanently excited synchronous motor; it is fitted between the combustion engine and the automatic transmission. The electric power generated by recuperation is stored in a bank of supercapacitors.

Researchers synthesize battery cathode from lignin derivatives

Green Car Congress

Milczarek and Inganäs describe how a class of organic compounds known as quinones allows the lignin derivatives to shed a proton and store this electric charge in its place. The polypyrrole is able to hold on to the loose proton until the charge is released and the proton returns to the quinone group of the lignin derivative.

Mercedes-Benz introduces Intouro K hybrid inter-city bus; 48V with supercaps

Green Car Congress

This current is stored and is available to the electric motor to support the combustion engine, especially when moving off, but also when accelerating. Supercapacitors serve as short-term energy storage units. The current generated by recuperation is stored in supercaps. Both the inverter and the electric motor are water-cooled.

Electric Cars and a Smarter Grid - Green Inc. Blog - NYTimes.com

Tony Karrer Delicious EVdriven

And in a true smart grid, electric cars will not only be able to draw on electricity to run their motors, they will also be able to do the reverse: send electricity stored in their batteries back into the grid when it is needed. In effect, cars would be acting like tiny power stations. While utilities such as E.ON
