Aurora Powertrains eSled

Increasing interest in preserving the world’s Arctic regions has generated strong demand among tour companies and eco-tourists for zero-emissions snow-going vehicles. An electric snowmobile would be quieter, emissions-free, and far easier to maintain than an IC-engined version.

Sigma Powertrain EMAX transmission

Rory Jackson explains how this modular all-electric gearbox can combine two motors to drive any size and weight of EV. High-voltage electric motors produce torque across a wide range of their rpm bands, enabling most electric cars on the road these days to achieve reasonably high power efficiencies with single-speed gear reductions.

Torque sensing

Twists in the tale Ryan Maughan explains the pros and cons of the various ways to measure motor torque As the market for electrified vehicle powertrains develops, so the quest to deliver improved efficiency and performance in electric drive systems continues. Maximising vehicle range for a given battery capacity is a key target of every […]

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.

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.

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 […]

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 […]
