MAN, Verkehrsbetriebe Hamburg-Holstein and Volkswagen begin pilot of 500 kWh second-life battery in charging network

Green Car Congress

In the Bergedorf quarter of Hamburg, a container with a total capacity of approximately 500 kWh has been connected to the depot charging network at the Verkehrsbetriebe Hamburg-Holstein (VHH) depot. One objective of the project is to develop a flexible battery storage concept which allows for the replacement of batteries.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

The concept behind V2G had gained traction in the late 1990s after California’s landmark zero-emission-vehicle (ZEV) mandate went into effect and compelled automakers to commercialize electric cars. And with the revival of the EV, the V2G concept was reborn. The experiment seemed to prove the feasibility of the technology.

KIT/IIT team demonstrates suitability of high-entropy oxides (HEO) as conversion materials for reversible energy storage

Green Car Congress

Recently, a new class of oxide systems, also known as high entropy oxides (HEO), was formulated and reported with first demonstrations for transition-metal-based HEO (TM-HEO), rare-earth-based HEO (RE-HEO) and mixed HEO (TM-RE-HEO). This concept was first reported for metallic high entropy alloys (HEA). Sarkar et al.
