Electric cars

Quantum batteries could charge electric cars faster than it takes to queue for gas

While electric cars can be great for fuel economy and the environment, one of their biggest shortcomings is the need to regularly recharge their batteries.

High-power charging stations in public areas can fully charge them in around 30 minutes, but home charging can take up to 10 hours.

All of that could change if scientists manage to successfully develop quantum battery technology.

Researchers theorized that if they could harness the mysterious power of quantum physics, it would be possible to charge an electric car in just minutes.

Currently, car batteries have “cells” that are charged in parallel independently of each other.

Quantum batteries would be able to charge all of these cells at once, dramatically speeding up the charging process.



Charging some electric cars can take up to 10 hours

It would work similarly to quantum computers, which process all equations simultaneously rather than in a slow, linear fashion.

The Institute for Basic Science presented their idea as follows: “A typical electric vehicle with a battery containing about 200 cells.

“Using this quantum charge would result in a 200x speedup compared to conventional batteries, which means that at home the charging time would be reduced from 10 hours to around 3 minutes.

“In high-speed charging stations, charging time would be reduced from 30 minutes to seconds.”

A common complaint from electric car owners is shorter-than-expected battery life on some models.

A driver who spent around £62,000 on an electric car has complained that the battery only lasts a few hours and is unable to take long motorway journeys without recharging.

After swapping his BMW Diesel for the new flash car, the Essex driver complained to the Telegraph that his car’s battery, which is supposed to have a range of 285 miles, only has a maximum range of 145 miles.

The disgruntled driver claimed his drive north to see his family over Christmas took ‘nine hours each way’ and was a ‘nightmare’.
