AVL BOBCAT 2 engine testing system

October 24, 2013  by  

 

AVL announced the launch of BOBCAT 2, the second generation of an affordable and integrated engine testing system from AVL’s COMPACT product line.

The company said that functional enhancements to BOBCAT 2 were designed to make the system more powerful and flexible, offering many features found in higher-cost test solutions.

Functional enhancements include the ability to generate a report template within BOBCAT 2 that eliminates the need to export testing data. The user can instantly access the test data necessary to optimize the engine.

ams chip monitors/balances Li-Ion cells

October 16, 2013  by  

 

ams AG said its new AS8506 eliminates the need for a powerful processor, complex software and serial communications links that are used today for cell monitoring and balancing in Li-Ion systems.

The firm described the AS8506 as “a vastly simplified and more robust method” of implementing cell monitoring and balancing in lithium battery systems.

The AS8506 performs distributed cell monitoring and balancing operations for stacked cell modules, including Safe Operating Area (SOA) checks and passive or active cell balancing.

STMicro Start/Stop-Compatible Amplifier

October 7, 2013  by  

STMicroelectronics’ TDA7802 automotive start/stop-compatible audio power amplifier is said to combine the performance and cost benefits of a digital input with the simplicity and enhanced efficiency of analog class SB-I amplification. It’s the first such device available for use in start/stop applications, according to the company.

The TDA7802 extends ST’s family of ‘green power’ products specially designed to support advanced technologies for cleaner cars, such as start/stop (micro-hybrid), which reduces emissions by cutting the engine instead of idling.

GE and Berkeley Lab explore water-based EV energy storage

September 2, 2013  by  

Scientists from GE and Lawrence Berkeley National Laboratory (Berkeley Lab) are collaborating to develop a water-based, flow battery for electric vehicles that could sell for one-fourth the price of car batteries available today and power an electric vehicle for 240 miles or more.

The flow battery would derive its power from an electro-chemical reaction that resides safely in a bath of water. Visit https://vine.co/v/hiJX6QlQOLQ to view a video demonstrating the technology.

The proposed flow battery uses water-based solutions of inorganic chemicals that are capable of transferring more than one electron, providing high-energy density. Discharge and re-charge of such flow batteries occur in electrochemical cells separated from energy storing tanks, which makes them safer.

China lab certifies PowerGenix

August 30, 2013  by  

PowerGenix announced that its batteries have achieved certification by China National Laboratory’s Tianjin Automotive Test Center.

Tianjin Automotive Test Center completed a comprehensive test matrix covering all aspects of advanced micro-hybrid vehicles to validate NiZn’s potential performance improvements.

The Tianjin Automotive Test Center certification indicates that PowerGenix’s NiZn batteries have passed all of the corporate standards and requirements for micro-hybrid vehicles, which are traditional gasoline or diesel-powered cars with automatic battery-powered stop-start systems.

According to PowerGenix, Tianjin’s certification gives PowerGenix a competitive edge in penetrating the growing micro-hybrid market in China.

dSPACE eases battery management system development

July 5, 2013  by  

 

Battery Cell Voltage Measurement and Balancing system performs high-precision measurement and control of cell voltages in Li-ion batteries.

New rapid control prototyping (RCP) offerings from dSPACE are said to simplify the development of critical battery management algorithms by enabling precise, fast measurement and control of cell voltages for modern Li-ion batteries.

Quick iterations with maximum control

Battery management systems (BMS) interact with several vehicle systems such as the powertrain, energy management, vehicle safety, infotainment, etc. These systems cannot be developed in isolation, but require easy-to-use, in-vehicle rapid control prototyping (RCP) systems that allow quick iterations with maximum control capability. dSPACE is extending its RCP portfolio to fulfill this need by introducing its Battery Cell Voltage Measurement and Balancing system.

Romax software streamlines driveline design

April 30, 2013  by  

 

Romax Technology announced a new version of CONCEPT, its software for planning, developing and testing gearboxes, transmissions and other sophisticated driveline components.

Romax also introduced CAD FUSION, a plug-in for moving model data quickly and easily between CONCEPT and Romax’s flagship product, RomaxDESIGNER, or third-party CAD and gear design applications and tools, and it introduced Dynamic FUSION, software said to improve the speed and accuracy of driveline-related multibody dynamic (MBD) analysis.

Gearboxes and transmissions

Romax focuses on the planning, design and manufacture of drivelines, including gearboxes and transmissions.

Intelligent battery sensor reference design from ams

 Intelligent battery sensor reference design enables use of latest ARM core automotive MCUs

ams AG released a reference design implementing a complete automotive Intelligent Battery Sensor (IBS) based on its AS8515 data acquisition front end. The reference design is suitable for monitoring the state of charge (SOC) and state of health (SOH) of the latest lithium-iron-phosphate automotive batteries as well as conventional AGM (lead-acid) batteries.

TI introduces multi-phase synchronous boost controllers

March 18, 2013  by  

Texas Instruments Incorporated (TI) introduced three wide-input voltage synchronous boost controllers with high efficiency and high power density.

Widest input/output voltage range

The LM5122Q multi-phase boost controller features the industry’s widest input and output voltage range, according to the company. The low quiescent-current TPS43060 and TPS43061 boost controllers feature 1-MHz operation and a small QFN package.

Increase efficiency up to 10%

TI’s new synchronous boost controllers increase efficiency by up to 10-percent over non-synchronous boost controllers by replacing the freewheeling diode with a synchronous switch. Lossless inductor DCR current sensing further improves efficiency and reduces heat dissipation to save board space and lower bill of materials cost. Each boost controller features thermal shutdown, frequency synchronization, hiccup-mode current limit and an adjustable line under-voltage lockout.

A collective approach can solve the EV industry challenge

December 3, 2012  by  

By Erik J. Spek, Chief Engineer at TÜV SÜD

Skeptical voices on the future of electric vehicles, or what I call “custodians of the status quo,” are numerous and often headline-making. After all, it is easier to point out flaws in an innovative concept than to offer solutions to improve what remains perhaps the most promising alternative to traditional fossil fuelled cars.

No one is denying the challenges the electric vehicle industry is facing, whether it is range, cost or safety; but a shift in perception is needed to accelerate the development of electric vehicles and mass-market adoption. Unconstructive criticism is counterproductive.
