BMW presents “Vehicular Small Cell” at Mobile World Congress; first mobile femtocell for optimized in-car connectivity

Green Car Congress

KG and Nash Technologies GmbH are presenting the “Vehicular Small Cell” research project, which aims to improve mobile reception in vehicles. A femtocell is a mini cellular base station typically used to provide improved indoor cellular connectivity in businesses or private homes. Low-power transmission also saves battery power.

Amprius’ silicon nanowire Li-ion batteries power Airbus Zephyr S HAPS solar aircraft

Green Car Congress

The silicon nanowire structure includes a metallically conductive nanowire core, metallurgically connected to the current collector. Each silicon wire is directly connected and does not need to rely on particle-to-particle contacts for conductivity; the silicon material remains in electrical contact over the entire cycle life of the cell.

A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. To address these needs, the A123 team presented a high-power, lithium-iron-phosphate chemistry with excellent rate capabilities.

BMW introduces Vehicular CrowdCell research project; mobile femtocells to optimize mobile radio networks

Green Car Congress

This project extends the concept of the “Vehicular Small Cell” presented last year in Barcelona. The BMW Group is teaming up with peiker and Nash Technologies to present a prototype of the “Vehicular CrowdCell” integrated into a BMW research vehicle. Low-power transmission also saves battery power. Earlier post.).
