Tesla has scored what could be a major sales boost in China. Shanghai’s municipal government has ruled that Model S buyers will be exempt from the $12,000 registration fee required to obtain license plates. A city official told Bloomberg (via Green Car Reports) that 400 Tesla buyers have already received the free plates. Like many large Chinese… Read more »

2014 Mercedes-Benz B-Class Electric Drive
After a gradual build-up, Daimler’s automotive brands are now showing their stuff in the EV arenas of three continents. Stateside, the spotlight lands on the new, competitively priced Mercedes-Benz B-Class Electric Drive. Daimler AG, the parent company of Mercedes-Benz USA (MBUSA), hasn’t been the most visible mover or shaker in electric mobility up to this… Read more »
Freudenberg Group’s new line of Li-ion battery separators
The separator is a critical component of a battery. It provides a barrier between the anode and the cathode while enabling the exchange of ionic charge carriers from one side to the other. For over 40 years, the Freudenberg Group has been producing separators for nickel-based batteries, such as the nickel-metal hydride (NiMH) cells widely… Read more »

This article is an excerpt from Tesla Motors: How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution by Charged Senior Editor Charles Morris. This 270-page book is a comprehensive history of Tesla, told by the entrepreneurs who made it happen, as well as an assessment of the company’s lasting influence… Read more »
Siemens saves weight and space with integrated motor and inverter
The latest idea for reducing vehicle weight comes from the German engineering colossus Siemens, which has developed a way to integrate an EV’s motor and inverter in a single housing. An inverter, which converts the battery’s direct current into alternating current for the motor, is a key component of any EV. Siemens’ Sivetec MSA 3300… Read more »
Sendyne’s new SFP101 precisely measures current using shunt of any material
A battery management system requires precise current measurements in order to derive State of Charge (SOC) and other important battery state information. To date, commercial shunt measurement systems are limited in their accuracy by two main factors. First, accuracy is affected by changes in temperature caused either by the environment or by the self-heating of… Read more »
Electric buses begin to take over the public transit world
The humble city bus is quietly (also smoothly and emissions-free) going electric. In the past couple of months alone, Chicago, Washington DC, Portland, Oregon and London have begun trials of battery-electric buses, and the Chinese city of Hangzhou has placed an order for 2,000. China’s BYD is building buses in California and planning a factory… Read more »
European EV sales – a very different selection from the US
The US and European auto markets differ in several significant ways, so it’s not surprising that the sales figures for the various plug-in models available look quite different across the water. One of the biggest differences is size. We Americans love our pickups and SUVs, while Europeans love cute little cars that would be laughed… Read more »
Livingston Products develops battery self-cooling system
Illinois-based Livingston Products has developed a new liquid cooling pump system that uses the heat from a battery to propel a proprietary cooling fluid through a system of tubes. The Transthermal Heat Bridge, the subject of more than ten individual patents pending, can be scaled to fit almost any battery configuration, according to the company,… Read more »
New imaging technique gives researchers an unprecedented look at the inner workings of batteries
Scientists around the world are testing new ways to look inside lithium-ion batteries to gain a better understanding of what happens during charging and discharging. A team of chemists and engineers at Ohio State University claims to be the first to use Neutron Depth Profiling (NDP) to track the flow of lithium ions into and… Read more »
