Interest in electric vehicles returned during the oil energy crisis of the 1970s and 1980s, but the cars never achieved mass production.Still, electric vehicles have been making a comeback since 2008, with the introduction of fully electric cars such as the Tesla Motors Roadster (and, subsequently, the Model S), and the Nissan Leaf..pass_color_to_child_links a.u-inline.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-relative.u-absolute.u-absolute--center.u-width--100.u-flex-inline.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.web_page .u-hover-bg--black-transparent:hover.
Many of today's electric vehicles run on rechargeable lithium-ion batteries — the same kind found in most laptops.
These are replacing the cheaper lead-acid batteries used in most older models of electric vehicles.
It will be interesting to see where they are five years from now, Litster said.
Everyone’s saying it: The future of driving is electric.
And normal cars for regular people are going the same way.
Combined, Ford and GM plan to offer 34 full electric models in the next five years.
The main disadvantages of today's hydrogen fuel cell vehicles are the lack of sufficient infrastructure for hydrogen refueling, and the cost of the catalysts, Litster said.
Platinum is one of the most commonly used catalysts for fuel cells, but it's very expensive, Litster said.
Battery swapping — in which a depleted battery is exchanged for a fully charged one — is one possible solution, and Tesla Motors has begun using this option.
Battery technology has improved dramatically, but "batteries are still too heavy and expensive, and don't have enough energy, which means a shorter range," Peng said.
