Tesla Battery Failures Make ‘Bricking’ a Buzzword - 24 volt lifepo4 battery pack

Bradley bermanmarch 2, 202an uproar recently caused a stir on the car blog because of a post about the Tesla sports car whose battery has been parked by the owner for more than two months
The battery that has been fully discharged cannot be recovered.
Although the controversy surrounding the incident continues
Bloggers argue about the responsibility of car owners to keep their batteries charged and the motivation to disclose details --
Tesla has confirmed the basic facts of the situation.
The event created a buzzword "bricking", a term from the top
The technology industry is often used to describe electronic devices where damaged software becomes useless.
In this case it's 1,000-pound lithium-
Ion battery pack for electric sports car-
A car, which costs about $110,000, has now finished production --
This is actually a brick.
At an electric car Conference in San Diego last month, Tesla Chief Technology Officer J. B.
Straubel told reporters that all batteries may be affected by this total failure mode, but less than 10 sports cars may be "vulnerable" to this problem.
He added: "If you run your traditional engine without oil, who would be wrong?
It should be the owner.
Since then, technical experts and E.
Car enthusiasts have been debating whether it is possible for the battery pack of an electric vehicle to be drained irrevocably and under what circumstances.
A few weeks after the Chevrolet Volt lithium fire
Due to federal crash testing under laboratory conditions, these failures provide material to critics who question the feasibility of the batterypowered cars.
Here are the answers to some of the questions raised by Tesla's battery situation: Q.
How did all this begin? A.
A description of a Tesla sports car in California, the battery of the car is completely invalid. com.
The key to the problem is that Tesla refuses the warranty because the owner does not insert the car in accordance with the owner's manual and other materials when parking.
According to a letter from J. , vice president of Tesla services, the replacement battery of Tesla's Los Angeles service center is priced at "about $40,000"Joost de Vries. AdvertisementQ.
How many Tesla sports cars have experienced this failure? A. According to J. B.
Straubel, Tesla's chief technology officer, said that "less than 10 cars" were "vulnerable ".
In an online report, the owner accused several battery failures that caused the car to be completely incapacitated.
Tesla spokesman Khobi Brooklyn said she could not confirm the number of battery failures. Q.
If you don't drive, why is the battery of the electric car running out? A.
All modern cars, not just electric cars, have systems to get power even when the car is closed and parked.
Clocks, anti-theft alarms, and audio systems are just a few devices that traditional car batteries can power at any time.
Electric Power System vehicles, including plug-in
In a hybrid, there are usually batteries
A management system that is always active.
These nannies monitor and adjust the temperature and charging level of the battery.
The challenge for automotive engineers is to minimize these consumption on batteries.
Called parasitic loss
Keep all systems running at the same time. Q.
Under what circumstances will the battery of the electric car run out and not save? A.
Tesla said that the battery of electric vehicles will be completely invalid only in extreme cases.
This happens if the battery is "discharged for a long time.
The chemical changes that occur will make it impossible to charge.
The electronic vehicle log on a sports car with faulty batteries records 36 days, from charging to zero to Tesla indicating a need for a full replacement. Q.
Why can't the battery of Tesla sports car be restored? A.
Because sports cars are missing 12-
Volt backup battery and wake up-
According to Jon Bereisa, the upfunction is a former GM engineer and is now the president of automotive marketing. That wake-
The Up function enables the technician to regain the exhausted battery.
"So, there is no need for a 12 volt voltage, no computer, no charge . "
Bereisa said in an emailmail.
"The Dead Computer means locking the steering, locking the parking, and locking everything.
He added: "So unless you get 12-
12 volt battery in-
Volt socket and leave it in the car for traction, the car will remain locked and the trailer will have to drag it to the plate carrier with brute forceforce winching. Advertising q.
Can this problem be prevented? A. Yes.
Electric vehicles can use faults-
The security system has a variety of features to prevent full discharge, said Tom Gage, chief executive of EV Grid. V.
America and the grid.
They include the ability to isolate the battery from any load (except monitoring) when the power is reduced, using backup 12-
Volt battery and separate wake-up-
Up "function, sometimes external 9-
The volt battery of the vehicle system can be restarted.
"The battery must be slow at this point --
But it can be completely restored . "Gage said. Ms.
Tesla's Brooklyn says more than 2,000 sports cars produced since 2008 "have no facilities to stop this complete discharge ".
Tesla said it plans to adopt the "deep sleep" model and other protection systems in the new S-car.
Tesla's company blog explains the failure.
The safety regulations for the new model are as follows: "The Model S does not allow the battery to be less than about 5%.
By then, the car will be able to sit for a few months.
Of course, you can charge the Model S to 0%, but even in this case, the battery will recover normally if you plug in within 30 days. ”Q.
How about a failure-
Security system work? A. A fail-
Safe basically disconnected E. V.
Battery packs for other vehicle systems that run out of batteries.
When cut off with the rest of the car, the battery will still run out, but it may take a year or more before the battery loses all power. Q.
All electric vehicle batteries that reach zero-of-
Brick charging? A. No. E. V.
Engineers say that in most cases, even if there is a loss of battery life, the battery whose power has dropped to zero level can be restored. As Mr.
"To brick the battery, it really has to be sucked dry," said geqi of the electric vehicle grid.
"Even if it runs out, there is hope, according to Prabhakar Patil, chief executive of battery company Compact Power and former chief engineer of Ford hybrid technology.
"If a battery is in zero charge for a few months, it does not in itself prevent you from charging," Mr. Patil said.
However, in order to save the battery, the vehicle must design a recovery process for this situation.
This may include the use of on-board 12-
Volt batteries or electrical connectors enable the vehicle's control system to return to service life, making it possible to charge the propulsion battery.
(Tesla sports car does not use the traditional 12-volt battery. ) Mr.
Bereisa of GM said. M.
The scrapped EV1 electric car used 12-
The Volt motorcycle battery can wake up the control system of the car and allow the power grid to charge. AdvertisementQ.
How long can the Tesla sports car stay without plugging in before the battery is completely exhausted? A.
According to data from February
Published 24 articles on Tesla's company blog, "if parked at a charging speed of 50% without plugging in, the earliest sports car will take more than two months to unload.
"Exhaustion is not linear, so it is difficult to determine how long it will take to reach zero from other charge levels.
At the Tesla sports car online forum, several owners reported an average loss of about 0. State 5%-of-charge per day. That half-
Experts generally believe this number is high. Q.
What systems did Tesla create to prevent the collapse of sports cars? A.
Tesla's main strategy is customer education.
At the time of purchase, the owner must sign a document confirming that the car needs to be inserted when parking the car for a long time.
The owner's manual explains the same requirements.
E-remind customers regularly
Insert during mail and service calls.
When the battery reaches a low charging state, the owner receives a sound and visual warning signal.
Tesla said it started with the production of Sports Cars 2.
0 (after the first car of about 500), a wireless communication system was added to inform the company of the battery that was about to run out. Q.
What did Tesla say to the owner of the sports car about the potential of bricking and how to prevent it? A.
Tesla's basic advice to customers is simple: if you're going to store a sports car, plug it in.
If for any unforeseen reason, the car will be unplugged
When the car is interrupted, the warning lights and beeps on the car will warn the customer that wireless communication (on later models) will inform Tesla and then Tesla will contact the owner.
Tesla will then try to contact the owner to charge the car. Q.
Is the brick sports car battery under warranty? A. No.
"Because this problem is avoidable, it is not covered by warranty," Tesla said . ".
"Again, the burning vehicle needs to change the oil regularly, otherwise the engine will be destroyed.
This is the responsibility of the owner. ”Q.
Are all types of electric vehicle batteries potential victims of complete irreversible failure? A.
If the battery is consumed slowly for many years, all batteries will eventually fail, but bricking can be avoided due to failure
Can maintain a certain level of security supply for many years.
Nissan said in a statement that Leaf's battery pack "will never be fully discharged" due to advanced batteries"
A management system designed to protect the battery from damage.
Kathryn Zachary, Nissan spokesman, said, "never.
