First look at Tesla’s new battery pack architecture

https://electrek.co/2017/08/24/tesla-model-3-exclusive-battery-pack-architecture/

Interesting, thanks for sharing!

I’d like to see someone do a video driving a Tesla 2800 miles from New York to Los Angeles. Including all the charging stations, planning, trials and tribulations along the way. Then calculate the average the speed. I wonder if they’d be able to make it across the Rocky Mountains without having to be towed to a charge station. A long up hill incline for 20 miles at 60mph would eat up a lot of battery juice I would think.

This comment below the article has me excited:

_BMW 21700 Lithium Cells specs:

· 60% more capacity than conventional 18650 cells
· 400% current capability compared to conventional 18650 cells
· Lighter than 18650 cells
· More active cell material
· Double total lifetime_

We live in good times! I’m really jazzed about how the new cell technology will change so many of the items we use each day.

Edmunds team sets cross-country electric record in Tesla

A team of drivers from car-shopping site Edmunds.com says it set a record for cross-country travel in an electric car, driving a 2013 Tesla S from Redondo Beach, Calif. , to New York, N.Y. in 67 hours and 21 minutes.

Edmunds says that broke the previous record of 76 hours and 5 minutes set by a team from Tesla.

Edmunds.com’s director of vehicle testing Dan Edmunds and photo editor Kurt Niebuhr stopped at 23 Tesla Supercharger stations during the trip.

The Edmunds team had no backup or support team, counting on the Tesla being reliable and the high-power recharging stations being frequent enough.

Edmunds and Niebuhr documented their run on the Edmunds site. They say Tesla was uncertain they’d make it because they were using a charging corridor that Tesla considered undeveloped.

ROAD REPORT: Cross-country record for electrics

Tesla S has a long range — well more than 200 miles — but the battery pack to store that much energy requires a long recharge. Tesla’s Supercharger stations use high power to fill the batteries in an hour or so instead of taking multiple hours.

The team figured the battery pack would fill faster if close to empty, so only put in as much juice as needed to reach the next Supercharger, rather than filling the battery pack as full as possible.

Often they arrived at the next plug-in with only a few miles of range remaining.

The drivers ate while the car recharged and took turns sleeping in the car.

They figure they lost an hour fussing with toll booths across the Eastern U.S.

They claim they didn’t dawdle, but avoided needlessly fast and aggressive driving that drains batteries quickly. Cross-country, on batteries, by the numbers:

Distance: 3,331.9 miles
Total time: 67 hours, 21 minutes.
Driving time: 52 hours, 41 minutes
Average driving speed: 63.2 mph
Total Supercharger plug-In time: 14 hours, 40 minutes
Average Supercharger plug-in time: 38.3 minutes
Number of Other Stops: 0
Total energy consumption: 1.06 Megawatt-hours
Total fuel cost: $0 (thanks to Tesla’s free Superchargers, available to all Tesla owners)

I could drive over 90% of my drives with an electric car with under 100miles of usable power at a time.

Everyone dislikes the electric cars limited range - why not keep the family´s 2nd car a petrol then, just in case :slight_smile:

Too bad the 35K Tesla will be sold here for atleast 60-70K so no electric vehicles for me during the next decade or so :confused:

They went Interstate 40 route instead of I-70. But it looks like they’ve installed charging stations in several places along the I-70 route through the Rocky Mountains. They would need them.

A bit off-topic, but a MUST SEE movie is “32 Hours 7 Minutes”.

I started watching it late-night just to “preview” the video quality, and stayed up to watch it start to end, it was that gripping.

Ftr, Alex Roy is mentioned in the article from theverge above.

So if one of the 18650 battery shorts, could that result in a fire?

The nice thing about a Tesla is it calculates range remaining depending on usage, then directs you to a charging station automatically so you will never run out of juice unless you ignore the display and drain it intentionally, similar to purposely running out of gas in a regular car. In english you drive at high speed with maximum heat and AC the car takes that into account, figures out how much further you can go and alerts you to go to the nearest station and tells you where it is with a map and has calculated you won’t run out of juice before you get there.

Also they want to do a coast to coast driverless EV test before the end of this year. I think they may be a bit optimistic on the time frame but this will include not running out of juice as well as having no driver.

You have inspired me to revive an old thread

No, since the cells have individual fuses.
