tesla model 3 teardown reveals impressive batteries and electronics — and serious design flaws

Tesla Inc.
Chief executive Elon Musk said his company is forming an edge in its ability to make electric vehicles at low cost and high efficiency.
These statements look more suspicious.
The latest blow to Tesla\'s production qualifications comes from Munro & Associates, a small company in Detroit.
Regional company that disassemble the new car and analyze its nuts and bolts.
Founder Sandy Munro has picked out the Model 3 sedan and praised them for their battery packs and electronics, but converted most of the other vehicles into expensive, heavy and poorly built ones.
For Tesla, the ability to develop mass production
Making a car is the key to its ability to survive.
Musk predicted that his electric robot
Automakers are leading other industries in the automotive industry, but face repeated delays and huge losses.
If Munro is right, Musk may have a more persistent problem in his hand: the first model he designed for the masses may be more important and expensive than the competitive model being developed.
\"Mechanically, I have nothing to say,\" Munro said last week in \"automatic launch after work\", a weekly show broadcast by Detroit Metro Radio.
\"If it could become more decent, they would drag the ground with everyone.
But they don\'t.
\"The weight of the Model 3 exceeds any vehicle of its size, in part because Tesla uses unnecessary materials and increases costs,\" Munro accepted Michigan at its factory in Auburn Hills on Wednesday. The long-battery-
The mileage version of the car makes the scale weigh more than 3,800 pounds, about 250 pounds more than GM.

A Tesla spokesman said that since production began last year, the company has been improving the Model 3 manufacturing process, and the standard deviation of all gaps and offsets of the car has increased by nearly 40 cents on average, special gap improvements can be seen in the trunk, rear lights and rear quarter panel areas.
The battery design and industry of Model 3 is very good.
According to Munro, the leading electronics company detailed his findings at an event at the Automotive News Association on Wednesday.
Its packaging is better in terms of power and efficiency than made by Samsung SDI Co. or LG Chem Ltd. , he said.
The two companies offer batteries to BMW\'s i3 and General Motors.

The circuit board of Tesla\'s latest sedan is also in terms of density with mobile phones, high-
Terminal computers or military fighters, Munro said.
Other car manufacturers should pay attention.
Mark Ellis, battery expert at Munro & Associates, said that the battery pack of Model 3 has more than 4,400 batteries, which may be used more than other car companies due to its new and unique chemical composition
He said the company\'s power, the Tesla Model S, was about 50 cents higher.
Ellis said the Model 3 also replaced a lot of wiring by using small printed circuit boards.
This makes the design not as complicated as it is used by other automakers.
\"It\'s not a Mickey Mouse costume you can fire,\" Munro said on the \"automatic production line.
\"Ignore Tesla\'s electronics and you\'re in danger.
\"The challenge for Tesla will be how to make cars efficiently at Musk\'s own assembly plant that says it uses too much automation.
In an interview with CBS earlier this month, the CEO said excessive use of robots was one of the factors that prevented the company from producing more Model 3 s.
Musk may have to follow his intuition and hire more humans.
This is not unprecedented, Munro said.
GM had called him to check the robots that the company had tried to use years ago, long before the company\'s 2009 bankruptcy.
The cars were not made with a lot of robots, he said, and eventually the car makers took them out of the factory.
Munro also has some harsh wording on the design of Model 3, which he says seems to be done by someone who lacks experience in physical engineering.
He said the sedan had eight to ten panels welded together, which produced weight without increasing strength.
The gap between the car body panels purchased and analyzed by Munro & Associates is inconsistent, and Munro says this may indicate that people on the assembly line are not properly trained.
A Tesla spokesman said the car body production of the new model is fiercely competitive with German luxury cars, and the company is working to make them more closely produced.
Electric vehicles have special requirements for protecting battery packs, and customer safety is a top priority for the company, she added.
Tesla\'s first-line hope is that the company\'s biggest weakness may be fixed: There are many experts who can buzz Tesla\'s factory.
\"It\'s hard for them to accept that I classify dinosaur technology as mechanical,\" Munro said last week . \".
\"We have hundreds of people in this area who can help them solve this problem.
I want them to choose one. Bloomberg.
