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

Green Car Congress

The electric motor on the Citaro hybrid assists the combustion engine when high levels of power are required, particularly when moving off. It does not serve to boost maximum power; the output and torque figures for the bus remain unchanged. The electric power generated by recuperation is stored in a bank of supercapacitors.

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. The disc-shaped major assembly with integrated power electronics and a thickness of eight centimeters has been integrated between the combustion engine and the automatic transmission.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

volts to 0.24 volts, so only 8% of the electrical energy is turned to heat. Because these “solid oxygen” cathodes are much lighter than conventional lithium-ion battery cathodes, the new design could store as much as double the amount of energy for a given cathode weight, the team says.

Each chemistry has its characteristics for power density, energy density, safety, cost and long-term reliability. The cells operate between -10 °C and 50 °C with available power being limited in the cold threshold and cell life being limited in the heat. volts at this point.

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. ’s power generation, he said.

Also, besides giving you the ability to charge at night when most utility rates are lower, future vehicle-to-grid (V2G) technology may allow you to sell some of your stored energy back to the utilities. Currently, there are some industrial facilities that use battery swapping to replenish the energy stores of electric forklifts.
