Sponsored by AVL Because integrated validation is only carried out during vehicle tests, development and validation of individual electrical components and the interaction of the overall system is often time-consuming. Using integration test stands, AVL is changing this process for electric drives. The majority of OEMs examine electrical and electronic drive components individually during the… Read more »

ClipperCreek’s new advanced control interface for HCS series charging stations
EVSE manufacturer ClipperCreek has unveiled a new expansion card for its HCS line of Level 2 charging stations. COSMOS, which can be added to any HCS series charging station for $184, was designed for developers, system operators, and system integrators – it features a simple digital load management interface, as well as UART Serial Communication… Read more »
Alta Motors says its electric dirt bike has world-class energy density
Alta Motors claims that its dirt bikes have a battery pack with energy density that’s among the highest of any production vehicle. With help from Scheugenpflug’s custom production equipment and Wevo-Chemie materials, the motorcycle builder says its thermal design was the key to achieving that. Seven years ago, a group of motorcycle and off-road dirt… Read more »
Leclanché’s new marine battery system earns international certification
Swiss battery-maker Leclanché’s new Marine Rack System (MRS), a modular Li-ion battery system, has won approval by the international certification body DNV-GL. Leclanché will use the MRS on the E-ferry in Denmark, the world’s largest electric ferry, which is equipped with a 4.3 MWh Leclanché lithium-ion battery, and is scheduled for launch later this year….

Southwest Research Institute consortium conducts independent battery benchmarking
Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
AKASOL says its battery modules ace long-term endurance tests
German battery builder AKASOL subjected the latest generation of its battery modules, AKAMODULE 46Ah and 53Ah, to an eight-month endurance test featuring a range of brutally extreme conditions. The test showed service life to even longer than expected. At 50 to 55 degrees, the battery components worked for 1.5 years in full cycles at a… Read more »
Converting bulk alloys to oxide nanowires could produce cheaper battery membranes
Image: Alloy in solvent A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could enable the production of thermally stable, strong battery membranes able to withstand temperatures of more than 1,000° C. In “Transformation of bulk alloys to oxide nanowires,” recently published… Read more »
MIT researchers investigate mechanics of sulfide-based solid electrolyte material
IMAGE: Using specialized equipment, a team from MIT did tests in which they used a pyramidal-tipped probe to indent the surface of a piece of the sulfide-based material. Surrounding the resulting indentation (seen at center), cracks were seen forming in the material (indicated by arrows), revealing details of its mechanical properties. Battery scientists are the world are exploring… Read more »
Volvo sells 8 electric buses to Harrogate in the UK
The Harrogate Bus Company of the UK has placed an order for eight Volvo 7900 electric buses. The vehicles will operate in Harrogate, 90 km northeast of Manchester. When the vehicles enter service in 2018, the project will be the first in the UK to use opportunity charging via the common interface OppCharge. The charging stations can also be… Read more »
Could a new supercapacitor technology replace batteries?
Supercapacitors, which feature long cycle life and high power density, are a common topic here at Charged – many foresee them working together with batteries. However, researchers from Augmented Optics in collaboration with the University of Surrey and the University of Bristol, have developed new electrolytes that they believe could be used to create supercapacitors… Read more »
