Ampaire flies first hybrid-electric regional aircraft
Ampaire’s Eco Caravan, a nine-seat regional aircraft, has made its first flight on an integrated hybrid-electric propulsion system. Ampaire expects it to be the first electrified regional aircraft to enter commercial service and the first in a series of larger Ampaire hybrid-electric aircraft. Fully electric aircraft are range-limited because of the weight and energy capacity […] More…
Sea Li-ion project sets out aims for electrifying ports
While many shipowners are considering battery power for propulsion, what is holding them back is the availability of shore-side power, the slow speed of charging and the capacity for it. The Sea Li-ion project has therefore been set up to address the knowledge gaps in battery use for ship propulsion. The EU-funded project has now […] More…

HVS unveils hydrogen-electric heavy goods vehicle
Hydrogen-powered commercial vehicle manufacturer Hydrogen Vehicle Systems (HVS) has announced a hydrogen-electric commercial vehicle that has been produced from a clean-sheet design. The Scottish company is showcasing its hydrogen powertrain in the form of a 5.5 t technology demonstrator, intended as a nod to its planned 40 t zero-emissions HGV (heavy goods vehicle) and with […] More…
User interfaces
Display on demand Peter Donaldson explains the essential characteristics for an EV’s user interface to be accessible, effective and intuitive. While governments’ plans to phase out IC-engined vehicles on short timelines is pushing individuals and companies towards EVs, they remain a small proportion of vehicles on the road globally. Most drivers will be new to […] More…
EV battery supply chain problems not all doom and gloom
Although global demand for new EVs is strong, the whole industry is still being disrupted by factors including the effect of the Covid-19 pandemic on supply chains, sanctions in response to the war in Ukraine, and inflation (writes Peter Donaldson). At September’s Battery Show in Novi, Michigan, LMC Automotive’s senior manager, powertrain forecasting, Kevin Riddell, […] More…
Hyundai’s Ioniq 6 design takes inspiration from cars, aircraft and nature
Hyundai Motor Company says its Ioniq 6 EV has a drag coefficient of 0.21 and an all-electric range of 614 km (WLTP-rated) on a single charge, thanks to lessons learned from some of the most streamlined shapes in automotive and aircraft history, as well as in nature. From the automotive realm, it cites the 1947 […] More…

VivoPower International has announced that it and its wholly-owned subsidiary, Tembo e-LV, have entered into a definitive agreement with Energy Trading Company Mauritius (ETC Mauritius) to sell, distribute and market Tembo electrification conversion kits for Toyota 4×4 second-hand vehicles in the Republic of Kenya. Under the deal, ETC Mauritius has committed to sell a minimum […] More…
Modified anodes boost cell cycling
Researchers in South Korea have developed a new method of modifying conventional anodes to improve the cycling performance of a battery cell (writes Nick Flaherty). The team, at the Gwangju Institute of Science and Technology, used a layer of graphene oxide – a single atomic layer of carbon – on a silicon anode to prevent […] More…
Automated battery manufacturing
Just push the button Cutting-edge research and prototype factories are helping to advance the automation of EV component manufacturing, writes Nick Flaherty Some car makers have had fully automated assembly of vehicles for many years, and EV makers are looking to achieve this ‘lights out’ approach, but with added issues for the assembly of lithium-ion […] More…
Bespoke chips for drivetrains
STMicroelectronics has launched a family of microcontroller chips designed specifically for electrified drivetrains (writes Nick Flaherty). The Stellar P microcontrollers are automotive qualified and combine the CAN-XL in-car comms standard to handle the demand for more real-time data with actuation functions. The controllers are built on a 28 nm fully depleted silicon-on-insulator (FD SOI) process. […] More…

Thomas de Lange
As many readers know, competitive engineering of e-mobility systems takes more than just high-quality electric parts: there is far more to an EV than its battery, motor and inverter. Many of the most cutting-edge and game-changing electric road, off-road, sea and air vehicles simply would not exist without innovations in non-electric components. When it comes to maximising actual kilometres per kilowatt, attention has to be paid to subsystems such as transmissions, suspensions, tyres and lightweight materials. More…
Solid-state cell with 3-minute charge

Cummins develops fuel cell e-turbocharger
Pumping air into an engine so that more fuel can be burned is a long-established means of persuading the engine to provide more power and, in the case of turbocharging, greater fuel efficiency (writes Peter Donaldson). These days, the same technique is being applied to fuel cells and for the same reasons. Cummins, for example, […] More…
Sodium Batteries
Research into sodium-ion batteries (NIBs) began in the 1970s and ’80s but was overtaken by lithium-ion battery (LIB) research in the 1990s. However, NIBs have recently re-emerged as a potential sustainable and less expensive alternative to LIBs as the demand for lithium drives up its cost, and there is growing concern over the safety of LIB cells, which can be prone to short-circuits and thermal runaway.
