Boston-Power raises $125M for China move News & Analysis 9/20/2011 6 comments GSR Ventures has led a $125-million investment round in Boston-Power Inc., a 2005 Massachusetts startup that has made progress in developing longer lasting, faster charging lithium-ion batteries aimed mainly at automotive applications.
Intelligent sensor, algorithms improve battery management Design How-To 9/19/2011 2 comments More than half of the vehicle breakdowns that are caused by the electrical system can be traced back to the lead-acid battery and could have been avoided by knowledge of the battery state. A battery management system provides the necessary information by fast and reliable detection of the State-of-Charge, State-of-Health, and State-of-Function in terms of cranking capability.
Gel electrolyte promises better battery News & Analysis 9/12/2011 5 comments Researchers at the University of Leeds, England have invented a polymer gel that they claim can be used to manufacture cheaper, flexible lithium batteries without compromising performance.
Mobile measurement supports onboard EHV high-voltage testing Design How-To 9/1/2011 Post a comment On-road EHV testing calls for considerably greater data acquisition and wiring challenges than stationary applications. Onboard or road test data collection within a typical test track environment subjects instrumentation to higher-than-usual shock and vibration inputs, placing greater mechanical demands upon components and systems.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
