Concept of the Day: Jaguar I-Pace
November 15, 2016 § Leave a comment
On the road in 2018, Jaguar says: the I-Pace has a useful claimed range of over 500km, 0-60mph acceleration in around four seconds, twin motors giving 400hp/700Nm, and all-wheel drive. Proper performance car stuff, then, though it’s a crossover-style high-riding five-seater hatchback rather than a sports coupe or saloon. The motors – which drive each axle – and 90kWh lithium-ion battery pack were designed in-house by JLR, and it’s rapid-charge compatible, of course; a full charge takes just over two hours for 220 miles or so. It’s on display this week at the Los Angeles auto show; more here. And more to follow from LA…
- BMW is about to embark upon phase 2 of its ‘ChargeForward’ trial with Pacific Gas & energy, to further explore grid-balancing and optimisation, load-shifting, adjusting charge timing to prioritise use of renewable electricity, and incentives to drivers for participation. Phase 1 – 100 i3 EV drivers in the SF Bay Area, July 2015-Oct 2016 – saw a 92% satisfaction rate when drivers were encouraged to delay their charging by up to an hour a day to reduce load on the grid; they were messaged according to their charging needs, and supplied with a static [second-life] battery to store solar energy. In 94% of the ‘demand response events’ – when PG&E requested drivers to hold off from charging – the required 100kW load reduction was achieved, and July 2015-August 2016, over 19,000 kWh were ‘shifted’ to avoid the use of carbon-generated electricity. Rundown here.
- Researchers from Stanford University and TUM [Munich] have concluded that – when required infrastructure is taken into account as well as electricity generation – plug-in electric vehicles are a better carbon-saving bet than hydrogen fuel cell cars. They modelled scenarios in 20 or 30 years’ time, and concluded that total energy use and carbon dioxide emissions in a community – for buildings as well as transportation – would be greater-reduced, and fossil fuel elimination more likely, if there was large-scale adoption of electric vehicles. Battery vehicles were also judged to be the more economically-attractive choice, given the growing economies of scale, and the cost of hydrolysis tech to produce hydrogen; although the latter could be made using ‘spare’ solar energy, the use of hydrogen as energy storage would be limited. In the analysis, battery vehicles were judged to be cost-competitive against ICE from 2025, and to require less than half the electrical energy. More on the study (in Energy, vol 114) here.
