Extreme low temperature charging is a problem, and American electric car owners complain that “driving EV in winter is a big test”

Many countries around the world are solving the problem of charging electric vehicles, accelerating the construction of charging facilities to make charging more convenient, and car manufacturers are constantly improving battery technology. However, when encountering abnormal low temperatures, electric vehicles may become a stumbling block for car owners. Lithium-ion batteries in electric vehicles don’t like freezing temperatures. Recently, they have faced extreme cold in the United States. Some Tesla owners have reported that the battery capacity has dropped significantly during the freezing weather and they cannot be charged.
A Tesla owner said to foreign media that when the outdoor temperature was 19°F , about minus 7°C, and the battery power was 40% , he charged it before going out, but the battery power did not change much after charging for 2 hours. Low, the charging efficiency became lower and lower, and finally stopped charging completely. His car had only 19 miles of cruising range at the time, so he was forced to cancel his vacation plans.
Another Taiwanese tech worker working in New York also reported Tesla’s battery problem in the community during the ice storm in New York. He bluntly said, “Winter is really a big test for electric cars. Model Y even prompts for AC charging when the temperature is below zero. You have to heat the battery first. In the past, only DC fast charging needed to be warmed up first, which caused the overall charging speed to be greatly reduced. If the car is parked in the parking lot and left on overnight in sentry mode , the power loss can drop to nearly 10% . “
Due to the chemistry of lithium-ion batteries, charging below freezing can damage the battery by causing lithium plating, so in cold weather the charging process spends some time heating the battery to the proper temperature, so it needs to be replaced Long charging time. The available power will be less at low temperatures. Some electric vehicle manufacturers, such as Tesla, will limit the battery power that can be used when the battery temperature of the electric vehicle is too low. The reserved power can be restored to normal when the battery heats up. The purpose is to Protect the battery.
Therefore, driving an electric car in a cold climate will greatly reduce the cruising range. The American Automobile Association (AAA) tested the Tesla Model 3 in a winter environment , and the average driving range was reduced by 41% in 20°F weather . The experiment involved stopping the Model 3 and allowing the cabin to cool down, so that when it was restarted, part of the battery power had to be used to heat the cabin, resulting in less actual cruising range of the vehicle, but the Tesla model was not equipped with it at the time of the experiment. Heat pump system, so the current car heating efficiency will be a little higher than resistance heating.
Batteries have limits
According to the Norwegian Automobile Federation, half of all new cars in Norway are electric vehicles. Tests have found that electric vehicles lose about 20% of their mileage in winter and take longer to charge in cold temperatures. Experts and car dealers provide electric vehicle owners with the ability to maximize cold driving mileage in winter, including plugging in the car at any time when not in use to keep the car warm, and setting a departure time to allow the car to warm up and the battery to charge first.
But batteries have their limits. The director of the Energy Institute at the University of Michigan said that batteries are like humans and like the same temperature range as people. Anything below 40°F (about 4°C) or higher than 115°F (about 46°C) is not will perform optimally.
Although it’s cool to drive a Tesla, it’s not a problem to charge it when it’s warm, and there are some driving guides you can refer to when facing severe cold weather occasionally, but if there are more and more chances of encountering abnormally low temperatures in the future, you don’t want to be entangled in so many technological settings. People, it may be more suitable to drive a gasoline car.

Decline in GameStop’s Quarterly Revenue

According to financial data, digital gaming sales growth at the Grapevine, Texas, store is not compensating for a drop in in-store purchases.
Despite the company’s best attempts to offset the fall in physical sales with growth in digital transactions, GameStop Corp. just reported its worst quarterly revenue dip in two years. In the three months leading up to October 29th, net sales dropped 8.5% to $1.19 billion, which was lower than the $1.39 billion predicted by two analysts. Loss per share after adjustments came in at 31 cents, which was higher than the predicted loss of 29 cents. The company is only worth $7 billion, and its stock is extremely volatile, therefore very few analysts cover it.
Since becoming chairman of the board this year, Ryan Cohen has been working to reinvigorate GameStop’s growth in Grapevine, which has slowed as customers switch from purchasing game CDs to purchasing digital downloads. To make matters worse, COVID-19 lockdowns crippled GameStop’s retail operation, and supply shortages on consoles have further impacted profits.
According to market research firm NPD Group, overall spending in the gaming business fell 5% in the third quarter compared to the same period a year ago.
Earlier this week, Axios reported that GameStop has begun a new wave of layoffs, with a particular focus on the team developing the company’s blockchain wallet. GameStop also announced layoffs of an undisclosed number of employees and the departure of CFO Mike Recupero in July.
In its earnings release, GameStop said nothing about layoffs
Cohen has been trying to get GameStop involved in digital assets, but it’s been difficult. The company began transitioning into nonfungible tokens in September, when it announced a partnership with cryptocurrency exchange FTX US. The parties agreed to work together on some new e-commerce and online marketing projects and stock some stores with FTX gift cards. However, the crypto market went into a tailspin in November after FTX imploded with $9 billion in liabilities and filed for Chapter 11 bankruptcy.
CEO Matt Furlong stated on an earnings call with analysts that GameStop does not have “a meaningful balance of any cryptocurrency.” We have not and will not put significant shareholder capital at risk by entering this market.
Furlong has stated his optimism for the continued development of digital assets
GameStop became a symbol of the meme-stock mania that swept the retail trading community during the pandemic, in which the price of specific stocks was driven up by online discussion of such stocks on Reddit and other social media platforms rather than by any actual business fundamentals. The stock price, which is down 40% so far this year, rose by around 1% in after-hours trading on Wednesday in response to the news.

Case of the alphabet U.S. drone operations expansion: Wing wants FAA’s blessing D.C. (Reuters)

The Google subsidiary Wing Aviation has applied for a waiver from some FAA drone regulations so that it can expand its operations beyond a single small city in Virginia, according to a notification published by the FAA on Friday. As of early 2019, Wing has supplied a multitude of services for locals of Christiansburg, Virginia, including both scheduled and emergency deliveries. With the goal of serving more people, “Wing is now aiming to expand and improve upon these operations,” the company claimed in its request for waivers from some FAA drone regulations. The organization promised to listen to petitioners before reaching a final call. The FAA was informed by Wing that the company had “made major investments targeted to strengthen both the safety and capacity” of drone operations in the United States. More than 17 months have passed with no reported incidents. Wing seeks FAA clearance to move remote pilot activities “to regional operations centers that can monitor and safely handle a greater number of airliners at once. When it grows, Wing aims to utilize a variant “that has been demonstrated to be dependable in commercial operations and is extremely comparable in its operating characteristics,” Wing said. Yet “to identify and accept this alternate aircraft version,” approval from the FAA is required.
In addition, during the interval, Wing requested that the FAA conduct operator line inspections once every 12 months rather than every three. According to the report, “current limitations will make it infeasible to grow a light-footprint, distributed operation across a neighborhood,” therefore the amendments “will assist assure that more American homes may experience the benefits of (drone) technology.” Small drones can now legally fly over people and at night without special permission under new FAA regulations that went into effect on Wednesday. The long-awaited guidelines require remote identification technology in most situations to enable drone identification from the ground, which is intended to alleviate security concerns.
