Video Summary
Here's a summary of the video review:Battery degradation is inevitable in electric cars, just like engine degradation in gasoline cars.
The reviewer's Tesla Model Y Long Range has about 48,000 miles on it after two years.
The Tesla app, with a Test Logic box, shows battery degradation, which is about 8.1% for this vehicle.
Batteries degrade fastest when new and then level off.
Tesla technicians suggest not worrying too much about battery degradation in Teslas.
The main cause of degradation is cell balancing, since battery packs have thousands of small cells.
Tesla recommends using the daily charging limit set by the car for regular use. It says to avoid charging it beyond 80% on a daily basis.
For long-range NCM battery packs, the reviewers are advised not to go below 30 % or 20 %.
Tesla recommends you occasionally drop the battery charge to near 0% and then charge it all the way to 100%. This is to have the computer determine where the true top and bottom of the batteries are.
Even at 0%, there is some buffer, so you won't get stuck. Tesla service says it is safe to get to a low state of charge.
The speaker notes the importance of using disk brakes in order to prevent the calipers from seizing.
He notes plans for future videos, including a look at 1200-mile road trips and general maintenance tasks.
Finally, this demonstration improved the battery health.
The maximum available power out of the battery increased.
