Supercapacitor breakthrough suggests EVs could charge in seconds but with a trade-off

Published

on

Supercapacitors may be providing an alternative to electric-car batteries sooner than expected, according to a new research study. Currently, supercapacitors can charge and discharge rapidly over very large numbers of cycles, but their poor energy density per kilogram —- at just one twentieth of existing battery technology — means that they can’t compete with batteries in most applications.

That’s about to change, say researchers from the University of Surrey and University of Bristol in conjunction with Augmented Optics. They have announced a breakthrough in supercapacitors, which are said to be between 1000 and 10,000 times more powerful than equivalent lithium-ion batteries and considerably quicker to recharge. However, they lack the storage capacity found in traditional automotive-grade lithium-ion batteries used in today’s electric cars. But Jim Heathcote, chief executive of Augmented Optics Ltd and Supercapacitor Materials Ltd, says consumers would likely still be happy with the trade off by having faster charging times. “A lot of people would be more happy with a half the range of a 300-mile, lithium ion-batteried EV, but a fast charging time”. If their research can be translated into the consumer market, EVs could re-charge in a time quicker than filling a vehicle with a tank of gasoline.

Tesla CEO Elon Musk has remarked in the past about the use of supercapcitors in electric vehicles, “If I were to make a prediction, I’d think there’s a good chance that it is not batteries, but super-capacitors.” The recent research could be a first sign that Musk’s prediction from five years ago could one day come to fruition.

Why a combination of batteries and supercapacitors is essential to a sustainable future

In the next few decades, fossil-fueled cars and home-heating systems will need to switch to electric power to avert catastrophic climate change. Electricity has tremendous benefits but also one significant drawback: it’s relatively difficult to store in a hurry. Batteries can hold large amounts of energy, but they take hours to charge. Capacitors are a solution to this dilemma, as they charge nearly instantaneously.

A supercapacitor solves the problem of storing a reasonable amount of energy for a relatively short period of time. Supercapacitors have been typically used as energy reservoirs to stabilize power supplies to electrical and electronic equipment. But supercapacitors can also be connected to batteries to regulate the power they supply. However, up until this point, they have only been able to store minuscule amounts of energy.

To truly have a feasible electric-powered lifestyle in which we can store and release large amounts of energy very quickly, we need efficiency in both batteries and supercapacitors. Supercapacitors help to solve the “energy versus power” conundrum. “Energy” is the capacity to do work. In physics, work is the act of exerting a force over a distance. While energy measures the total quantity of work done, it doesn’t say how fast you can get the work done. “Power” is the rate of producing or consuming energy. Supercapacitors can bridge that divide and solve the inherent trade-off between EV energy and power.

Dr. Brendan Howlin of the University of Surrey said: “There is a global search for new energy storage technology and this new ultra-capacity supercapacitor has the potential to open the door to unimaginably exciting developments.”

They hope to have a working prototype by spring 2017. “We are now actively seeking commercial partners in order to supply our polymers and offer assistance to build these ultra-high-energy density storage devices,” said Heathcote. In current form, the high energy density supercapacitors could make it possible to recharge mobile phones, laptops, or other mobile devices in just a few seconds.

A fleet of supercapacitor-equipped buses is already in use in China, although they do not achieve the range proposed by the Surrey research team.

Kia gains Tesla Supercharger access and issues a big apology

Kia gained Tesla Supercharger access and respect from Tesla fans in the same day.

Published

Kia EV6, EV9 and Niro Owners Gain Access to Over 21,500 Tesla Superchargers

Kia has announced that owners of the EV6, EV9, and Niro EVs have officially gained access to over 21,500 Tesla Supercharger locations in North America.

However, its announcement also contained an apology to Tesla.

First, Kia said that its three EV offerings will have access to Tesla’s expansive Supercharger Network. More than 40,000 DC fast chargers are available to Kia EV drivers, a major uptick as Tesla Supercharger access nearly doubles the number of accessible piles.

Sean Yoon, President of Kia North America and Kia America, said:

“Kia is committed to an exceptional ownership experience, and expanding the network of available DC fast chargers to our EV customers is an important component to maintaining the brand’s leadership in electrified mobility. Now, with access to the Tesla Supercharger network of DC fast chargers, our EV owners can feel even more confident in their decision to purchase or lease a fully electric Kia vehicle.”

Kia owners who have a CCS1 Charging Port will have access to an NACS adapter through dealerships. This will enable compatibility, as current inlets are not NACS, the port that Tesla utilizes.

However, Kia will eliminate the need for this adapter starting with the 2025 EV6 and 2026 EV9. These will come standard with NACS inlets.

We mentioned Kia included somewhat of an apology to Tesla, which is related to social media posts from “certain Nordic distributors,” as the company puts it:

Kia said in its announcement:

Kia America is aware of marketing posts by certain Nordic distributors. These initiatives were developed entirely independently by those distributors, without direction from Kia AmericaKia Europe or Kia Global. We want it to be clear that these posts do not reflect the position of Kia America, and we remain committed to clear and professional communication that reflects our values.”

The company also said that it “condemns the recent attacks that disrupt the availability of convenient and affordable charging for our customers.”

Tesla adds new child protection feature to mobile app

Tesla is rolling out within its mobile app a new feature that aims to save the lives of those forgotten in the car.

Tesla is bolstering its in-car safety system with the addition of a new feature that aims to protect children left in the vehicle, an extension of a feature it introduced with the addition of 4D radar systems.

Children are, unfortunately, victims of accidents even when a vehicle is not in motion. A report from 2024 noted that 37 children under the age of 15 die each year because they are left in cars, usually dying from heatstroke.

Tesla has made a few attempts to eliminate the possibility of this happening. Back in September, coding from Software Update 2024.32 noted that the company would be using an alert system to warn people of children left behind:

Tesla set to roll out new child safety and navigation features, coding shows

This was enabled by the use of a wave sensor within the cabin, a piece of tech Teslarati found in a filing back in 2021 with the FCC.

The entire idea behind this addition to the vehicles was to alert owners if there were passengers left in the car.

Now, Tesla is adding another level of this to its mobile app, according to a decompile of the Version 4.44.0 update, which is rolling out to customers now.

Tesla App Updates on X revealed a “Child Left Alone Detection” feature in the new app version, which has a few strings from a software perspective:

  • Cannot turn off climate when Child Left Alone Detection is active
  • Climate failed to start. Climate is unavailable when Child Left Alone Detection is active.
  • Climate controls are disabled when Child Left Alone Detection is active
  • Unable to start software update while a child is detected in your vehicle

It appears that, if the vehicle detects a child or another occupant in the car, climate controls will be disabled through the app in an attempt to maintain a proper cabin temperature. Turning the temperature up or even turning climate control off from the app will not be possible.

This is a major update to this feature as it only bolsters the safety of the occupants in the event that they are left behind. Of course, many of us might ask, “How do you leave a child in the car?”

However, it happens, as past events have shown, and this is a great way to eliminate it from happening in Tesla vehicles.

Tesla FSD ruins other intelligent driving systems for NIO Superfan influencer

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands,” Lee wrote.

Tesla Full Self-Driving (FSD) has been making waves in China, with owners pushing the system to its limits on what appears to be a regular basis. Videos of Tesla drivers in China show FSD navigating the trickiest of roads, from busy city streets to narrow, unpaved paths in rural areas.

And as per an influencer and NIO superfan, FSD is ruining other driver-assist systems from other automakers in China.

FSD Ruins It For Influencer

China-based influencer and NIO superfan Andy Lee recently shared his thoughts about FSD on social media. As per Lee, Chinese intelligent driving systems are overhyped by marketing. But once he personally experienced FSD’s capabilities, he became disillusioned with the offerings of domestic carmakers.

“Since I drove FSD, I have been disenchanted with all the ‘driving assistance’ of domestic brands. I once thought that the ‘driving assistance’ of domestic brands could beat FSD in seconds, but it seems that I was wrong. Not only did they fail to outperform FSD, they were actually crushed in reverse,” Lee wrote in his post.

FSD could very well become Tesla’s moat since even cars that are equipped with the same hardware would not be able to perform similarly unless they have access to the company’s training data and software. Tesla’s fleet is ever-growing as well, which means that FSD will only get better over the years.

Unsupervised on the Horizon

Tesla is already using FSD Unsupervised for its vehicles that are produced in the Fremont Factory and Gigafactory Texas. As per Elon Musk during the Q1 2025 earnings call, he expects Tesla to be able to roll out FSD Unsupervised to consumers before the end of this year. He also highlighted that Tesla is being extremely careful with FSD Unsupervised’s rollout.

“Before the end of this year. Not necessarily — I say within the U.S., like we do want to test — at Tesla, we’re absolutely hardcore about safety. We go to great lengths to make the safest car in the world and have the lowest accidents per mile in. 

“So we want to be very careful. We want autonomy to be definitively safer than manual driving. So it’s not enough that it just be as safe. It needs to be meaningfully safer than if the car’s manually driven,” Musk stated.
