EV dynamics

How a car moves in response to the forces acting on it is a fundamental determinant of safety, comfort, energy efficiency and driver engagement, and electrification of the powertrain profoundly affects that dynamic behaviour. This influence results from differences in the vehicle’s overall mass and its distribution, when compared with IC-engined vehicles, along with the speed and precision of response inherent in electrical machines.

Towards a 1000-mile range

One thousand miles is a nice, round number, and as a range for a battery EV it is a marketing department’s dream. However, there is real value in such a long range if it can be achieved by a production roadcar in representative trim rather than niche vehicles and technology demonstrators.

ZeroAvia hydrogen-electric aircraft

As detailed in the first issue of this publication (Winter 2018) through our discussions with Pipistrel about its Alpha Electro aircraft, it is just as feasible to develop (and certify) a two-to-four seater plane to run on battery power as it is with a roadcar. While serious optimisation of the battery and overall system weight must be undertaken to make small battery-electric planes flightworthy, it is empirically achievable.

Honda to start battery-sharing service for electric rickshaws

Honda has announced plans to begin a battery-sharing service for electric rickshaws in India in the first half of 2022, using the Honda Mobile Power Pack e: (MPP e:), its new portable and swappable battery. There are more than 8 million auto rickshaws in India, and they are an essential means of daily transportation for people. In urban areas, they are powered mainly by compressed natural gas and have been a key challenge for electrification.
