High-voltage breakout module needs no power meters or current transformers

Measurement and data technology company CSM has unveiled a new HV breakout module designed to meet the international safety standards required for the use of equipment in HV applications on EVs. The company says it simplifies the instrumentation, improves accuracy and reduces costs compared with systems that have not designed for in-vehicle use. When combined […]

Sono Motors’ Sion gets more powerful battery with greater range

Munich-based mobility provider Sono Motors has announced it will use a more powerful, 54 kWh, battery for use in its Sion solar EV. The new LFP (lithium iron phosphate) battery extends the vehicle’s total range by up to 305 km and its maximum charging power by up to 75 kW. The additional range provided by […]

GM to use US lithium for next-generation EV batteries through closed-loop process

General Motors has agreed to form a strategic investment and commercial collaboration with Controlled Thermal Resources (CTR) to secure local and low-cost lithium. The lithium will be produced using a closed-loop, direct extraction process that results in a smaller physical footprint, no production tailings and lower CO2 emissions than traditional processes such as pit mining […]

Thermal Management 2020

Peter Donaldson reports on the methods and materials for keeping EV batteries and other components in their optimum temperature range. Thermal management is the art and science of moving heat energy around to keep various components of a vehicle – and its occupants – at safe, efficient and comfortable working...

Battery Testing

Battery test systems are proving key to speeding up the development times for new batteries, as Nick Flaherty explains. At the heart of testing battery cells, modules and packs are the levels of voltage and current. Temperature and pressure are increasingly important conditions ...

Battery materials

Nick Flaherty reports on how recent advances in materials are leading to EV batteries with ever-growing energy densities. Battery systems for e-mobility platforms are based largely around lithium chemistry. Liquid lithium salts with graphite anodes and composite metal cathodes are the dominant combination for battery cells...

Liebherr ETM Series

Developing these all-electric cement mixer trucks has meant blending the bespoke with the off-the-shelf. Rory Jackson reports. The conventional cement truck is a diesel-powered vehicle that spends much of each working day at a standstill. However, whether it is having concrete...

Electrolyte detection outs cell leaks

Cell leakage in lithium ion batteries is bad news, so battery makers want to find any that happen during manufacture or assembly so their quality control teams can prevent early failures and minimise warranty costs, while drivers need confidence, safety and low servicing costs. Sandra Seitz from vacuum analysis and test instrument specialists Inficon explained […]

vRbikes vR3

Rory Jackson looks at how this three-wheeler has been designed to carry as much cargo as possible in the smallest footprint possible. Given that an electric powertrain brings with it lower maintenance times and costs compared with ICE powertrains, so more and more EV developers are looking to ‘right-size’ their vehicles into smaller and more compact architectures, for ease of use and...
