GM investigating ultracap-based Active Energy Recovery Buffer as low-cost mechanism to improve conventional vehicle fuel economy

Green Car Congress

GM is exploring the use of an ultracapacitor-based Active Energy Recovery Buffer (AERB) scheme as a low-cost means to improve fuel economy in conventional vehicles; results of a simulation study presented at SAE 2011 World Congress showed improvement of up to 1.3% liter engine and a six-speed transmission. —Gopalakrishnan et al.

Santa Clara VTA partners with Proterra and Scale Microgrid Solutions to charge 34 electric buses with solar-powered microgrid

Green Car Congress

In the event of an extended power outage, such as a public safety power shutoff, electricity stored in the microgrid’s battery storage system can provide back-up power at VTA’s Cerone bus yard to allow the agency to continue operating battery-electric buses, serving riders and providing emergency transport if needed.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. Total cost of implementation is much less than $10/1%, he said. Source: Borgwarner.

T-Mobile partners with SpaceX to ‘end mobile dead zones’

Teslarati

T-Mobile phones will be connected to SpaceX Starlink satellites late next year. “That is incredible because it’s a lot like putting a cellular tower in the sky, just a lot harder,” Sievert told the crowd at the SpaceX, T-Mobile event. . The best part about T-Mobile’s Starlink-connected service is the price.

MAHLE Powertrain presents new prototype 48-volt battery for mild-hybrid vehicles

Green Car Congress

Mild-hybrid vehicles need to recover energy efficiently and at a relatively high power during deceleration events. Thus a compact and cost-effective battery that is capable of high charge and discharge power levels relative to its storage capacity (high C rates) is desirable.

Hexagon, Hyundai and Valeo unveil a high-precision vehicle positioning system

Green Car Congress

For example, after an emergency braking event, the vehicle will be able to send information about the maneuver and its exact location—including which part of the road it’s on—to other vehicles, making it much easier to anticipate the response required for other vehicles.
