EV battery replacement rare, most covered by warranty [Study] By Techagents

Battery replacements are rare in electric cars, and most replacements occur during the life of the vehicle’s warranty, concludes a recent study by Recurrent Motors, which provides battery health reports and range estimates for used electric cars. does.

Based on a sample of 15,000 cars, recidivism researcher Liz Najman found that only 225 cars (1.5%) had their batteries replaced outside of a battery recall.

The study also found that battery degradation is not linear. This happens rapidly in the first few years of a vehicle’s life, then slows down as it ages.

Battery replacement can be a serious issue for the EV owner. A new battery can cost from US$5,000 to US$22,000 and up to US$100,000 for a luxury brand like Jaguar.

Although car makers say EV batteries should last 20 years, Najman wrote, there is little understanding of how they degrade over time, but so far, it seems that EV batteries are far from spec. have a very high lifespan because there are so few of them replaced even after the eight-year, 100,000-mile warranty period expires.

“EV batteries are exceeding basic expectations because battery management systems are more sophisticated than most people realize, and early adopters are well educated about battery health,” Andy Gerberson, head of marketing at TechNewsworld, told TechNewsworld.

stay away from fast chargers

Edward Sanchez, senior analyst for automotive at TechInsights, a global technology intelligence company, explained that engineers design modern EV batteries to last a typical vehicle lifetime of 150,000 miles.

“Some are long gone,” he told TechNewsWorld.

The auto industry, however, appears to be adjusting its outlook on vehicle lifespans.

“The industry is recognizing that most vehicles are on the road for much longer than 10 years and 150,000 miles,” said Sam Abuelsamid, principal analyst for e-mobility at Guidehouse Insights, a market intelligence company in Detroit.

“The average age of a vehicle on the road in the US is more than 12 years, and it is not unusual to have vehicles with 200,000 to 300,000 miles,” he told TechNewsWorld.


“The industry knows that, and it wants to reduce the risk of the owner replacing the battery during the useful life of the vehicle,” he continued. “They’re trying to align battery life with the life of the rest of the vehicle.”

EV batteries can last for the life of the car if they aren’t “cooked,” said Rob Enderle, president and principal analyst at the Enderle Group, an advisory services firm in Bend, Ore.

“The battery that cooks are Level 3 fast chargers, like the battery in your smartphone will wear out faster if you’re constantly charging it,” he told TechNewsWorld.

Abuelsamid also recommended reducing the use of fast chargers. “If you charge a battery at a slower rate, you’ll put less strain on it,” he said.

Charging your battery is a physical process that moves lithium ions and electrons around in the cells. At faster charging rates, physical processes are more forceful, and battery materials are subjected to greater physical stress or microscopic damage.

With very high voltage charging, such as DC fast charging, a lot of heat is also generated, which is not ideal for battery longevity, it continued. DC fast charging is the double bacon cheeseburger of charging: great on road trips but best avoided on an everyday basis.

heat is a battery killer

Experts recommend never to discharge the battery below 10% capacity or charge it above 100% so as not to stress the battery and cause premature dendrite formation.

“Battery corrosion is typically caused by the formation of dendrites, which are metal projections that can form on a lithium surface and penetrate the solid electrolyte, eventually moving from one electrode to another and shorting out the battery cell.” Can,” Sanchez explained.

He added that the exception to the 100% rule is Lithium Iron Phosphate (LFP) batteries, which are recommended to be 100% charged for the battery management system to obtain more accurate readings.

He noted that LFP batteries typically operate at a lower voltage than those with other chemistries.

Lithium-ion batteries used by EVs differ in several ways from those used in consumer devices. Consumer appliance batteries are engineered to last only two or three years, whereas an EV Li-ion can drive a vehicle for 150,000 miles and still retain 70% capacity.


One of the most important differences between lithium-ion batteries used in consumer devices and EVs is thermal management, Abulsamid noted.

“Laptop and phone batteries have no thermal management,” he said. “There is nothing to control its temperature over the lifetime of the battery.”

“The faster you charge a battery, the more heat goes into that battery,” he continued. “Heat is a killer for batteries. If a cell gets too hot, it damages the cell internally.”

“In a vehicle, the battery has a lot of sophisticated thermal management that works hard to keep the battery temperature at its optimum, neither too cold nor too hot,” he explained.

Avoiding the Solid Waste Apocalypse

As batteries degrade, the study found that the range of an EV declines. For example, Tesla’s Model S, with its 100 kilowatt-hour battery pack, loses about 75 miles of range after 100,000 miles on average.

However, the older Model S, which has smaller 70- and 85-kilowatt-hour battery packs, lost almost no driving range after covering the same distance.

By comparison, the 2014 and 2017 models of the BMW i3s clocked 100,000 with about 80% of their original battery capacity remaining.

Meanwhile, the 2021 Hyundai Ioniq 5 lost about 15 miles of range over the first 20,000 miles, but saw no further decline through about 90,000 miles.

While some see EVs as a necessary step toward addressing climate change, others see a deluge of hazardous waste generated by vehicles. According to some experts this should not be the case.


“As EV production increases, there will inevitably be end of life materials management, but companies like Redwood Materials – founded by Tesla co-founder JB Strobel – Li-Cycle and others are working to move beyond this issue and Recycle responsibly and recover EV batteries,” said Sanchez.

“Some utilities also repurpose used EV batteries as a means of load-leveling the grid and night-time renewable energy storage,” he continued.

“Those who claim that EV batteries will be a catastrophic environmental disaster do not factor in the value of reclaimed elements and metals from EV batteries, which will have significant demand in the future,” he said.

Abuelsamid agreed that we can avoid the solid waste problem.

“You can recover 98% of the important minerals in a battery during recycling,” he said. “Since it is unreasonable to expect that we are going to meet all future demand for batteries with new materials, the industry will rely heavily on recycled materials.”

“We don’t want to throw batteries in landfills,” he declared. “It’s not a viable option.”

More bots, more money, rare talent By Techagents

More online fraud, recession-resistant budgets and continued talent shortages can be expected in 2023, according to cybersecurity professionals who spoke with TechNewsWorld.

Online fraud, driven by persistent supply chain constraints and bot proliferation, will continue to rise in the coming year, predicted Benjamin Fabre, co-founder and CEO of Datadome, a bot and online fraud protection solution maker in New York City.

“If you look at the volume of threats, they’re going through the roof, and it’s not going to slow down,” he told TechNewsWorld.

Scarcity caused by supply chain constraints has driven up the prices of many commodities creating an attractive environment for fraudsters. “We are seeing limited stocks of products creating a bubble around their prices, driving more bots and online fraudulent activity, which I expect to continue in full force into 2023,” Fabre said.

The use of bots is gaining momentum in the new year. “We’ve only recently started to see this shift,” said Fabre’s colleague, Datadome’s head of research Antoine Vastel, where a lot of individuals have started using the app to monitor changes in housing prices, monitor the availability of gaming consoles, and more. Created their own bots to scour the markets with browser extensions.”

“We don’t think it’s going to stop, because it’s getting easier and easier to build advanced bots,” he told TechNewsWorld.

spend optimism

Wastel also forecasts the expansion of scaling activities and the use of scraper bots in 2023.

“While influence scaling is mostly used to affect concert tickets, it has spread to more and more products – sneakers, gaming consoles, GPUs, luxury items,” he explained. “I anticipate that with current product shortages and supply chain challenges, scaling will accelerate as the ability for resellers to raise money expands to new items and products across industries.”

He also said that more and more tools are appearing to make it easier to build advanced bots. “Whether it’s open-source libraries that enable attackers to mine their fingerprints or bots as a service that make building advanced bots as easy as making an API request, we think it’s time for scraper bots to take off.” will support construction,” he said.

Despite warnings of a recession by Cassandra, there remains optimism in the cyber security community about spending in 2023. Alberto Yepez, co-founder and managing director of Forgepoint Capital, a venture capital firm in San Mateo, California, pointed out that in 2021, cyber security spending is expected to increase by 12% from the previous year to about US$150 billion, and by 2022 spending is expected to cross $156 billion.

“This trend will continue into 2023 as the threat landscape becomes increasingly more dynamic and complex,” he told TechNewsWorld.

“With ransomware skyrocketing, organizations will look for support in modernizing their defenses and reengineering threat detection and response capabilities realizing that attacks are now inevitable,” he explained.

Yépez continued, regulatory compliance standards, cloud migration, and global digital transformation in business and government will further drive the market, especially as the hybrid workforce model evolves from a pandemic response to a regular way of doing business.

“All of these components help organizations meet business needs, but at the same time complicate their cyber security posture and create the need for a design-to-scale approach,” he said. “As a result, cyber security will continue to solidify itself as a key enabler in business operations, and organizations will prioritize proactive investment in 2023.”

Dangerous Cost Reduction

JD Hanson, CIO and CISO of Code42, a national endpoint security and data protection company, admits that some organizations will want to cut corners by cutting cybersecurity budgets, but stresses that they do so at their own risk.

He told TechNewsWorld, “Once the rumble of economic uncertainty starts rolling in, wary CFOs will start looking for areas of unnecessary spending to keep their company ahead of the game.”

“To the uninformed C-suite, cyber security spending is sometimes seen as an added expense rather than an essential business function that helps protect a company’s reputation and bottom line,” she continued. “These organizations may seek to cut costs by reducing their investment in cyber security equipment or talent, effectively reducing their company’s ability to properly detect or prevent data breaches and making them potentially catastrophic.” Can open up to the results.”

“This should be of particular concern amid continued ransomware attacks, and 2023 is expected to be another challenging year,” she said. “Companies that retain efficient cyber security resources will do better in the long run than companies that make sweeping cuts.”

Fabre said he does not see a negative impact on cyber security to the economy in 2023 because the cost of not investing in cyber security is too high. “Companies have a lot to lose – financially, reputationally, competitively – if their or their customers’ data is breached.”

“When you consider the rapidly changing legal and regulatory environment companies are now operating in,” he continued, “the risk of not being able to conform or secure privacy outweighs the short-term benefits of reducing cyber security budgets.”

The talent gap will continue

As in the previous years, in 2023 also the workforce problem in the cyber security industry will continue. generations to enter the field,” said Carolyn Vignolet, senior vice president of research and development at OneSpan, an identity security company in Chicago.

“Cyber ​​security education is important, and while we see more universities developing cyber courses, they are still very small compared to the significant challenges organizations face,” he told TechNewsWorld.

“For this new generation to be successful,” she continued, “universities must expand cyber education and provide real practical cyber training, not just theoretical training.”

He said that companies and employees also need to play their part. “Every person in an organization plays a role – even if it’s just raising awareness of phishing emails and avoiding unsecured links,” she said.

Vignolet urged organizations to better support their cyber teams. “As cyber leaders, we have a responsibility to create a safe environment and to make this known to anyone who is interested in this area,” he said.

“In fact, one of the most important key performance indicators to look for within employee engagement surveys is whether employees feel comfortable talking to leadership,” she said. “This is the strongest way to avoid burnout as this growing talent gap continues through 2023.”
