Smart EV Chargers Could be Used to Tax Future Electric Car Owners

By Gary Cutlack on at

The next generation of smart electric car chargers come with the ability to throttle charging rates to alleviate potential bottlenecks in local areas, but there's one additional tool within the chargers that could herald a future in which EV drivers are taxed for their power.

The government-sponsored public chargers could, or at least they have the technical ability to, send a signal back to the electricity supplier to tell it how much power is being used by an electric car. This is currently so demand can be managed, with charging rates limited or charging delayed entirely by a few hours if there are too many EVs all arriving at work or home and trying to reload their batteries at the same time.

However, this information exchange could become a mechanism to tax the pumping of power into batteries, as a government of the near future faces apocalypse once the petrol and diesel tax income begins to dry up. Experts suggest that this may only be applied to charging at higher rates while on the go, which could mean electric drivers of the future learn to prefer daisy-chaining extension leads and trickle charging their cars at home on the slow, were public chargers to attract more expensive taxed rates.

It's all hypothetical right now, at least, even though the system that could allow the taxing of the fuelling of EVs appears to be being put into place. [Autocar]
