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.

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.

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.

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.

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.

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.

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.
