Efficient Drivetrains expands California facility to support 5,000 drivetrains per year

Efficient Drivetrains, Inc. (EDI), a provider of hybrid and electric drivetrain solutions, will be moving its Dixon, California vehicle engineering and support operations into a new 10,000-square-foot space in February. The expansion will support the manufacturing of up to 5,000 drivetrains annually, as well as large numbers of vehicle engineering and upfit projects. The company… Read more »

Nanoscale measurement of lithium metal could lead to suppressing dendrite formation

Lithium metal, which can store more energy than carbon, would seem to be an ideal anode material, except for one serious flaw: dendrites, tiny needle-like branching structures that can grow through the battery, eventually causing a short circuit. Now, a joint team of researchers from Caltech and Carnegie Mellon University has measured the strength of… Read more »

Batteryuniversity has the tools to test the biggest batteries

German firm Batteryuniversity (BU) has introduced new test benches capable of testing the largest EV batteries. BU’s new 120 kilonewton shaker can handle a weight of 800 kg, and can test random profiles, sine sweep, superimposed sine and shock impulses. Frequency can be set between 5 and 2,500 hertz. A large low-pressure chamber (8x3x3 meters)… Read more »

New concept for current and voltage sensors could enable simpler battery packs

Engineers at Germany’s Ruhr-Universität Bochum (RUB) have developed a new concept for current and voltage sensors that may be particularly relevant to EV batteries. Battery monitoring typically requires as many current and voltage sensors as there are individual cells. RUB’s system uses only one of each, regardless of the number of cells. Moreover, both sensors… Read more »
