Battery based electric vehicles of today and tomorrow.

Wall Connectors are nothing but enhanced extension cords.

Tesla.com lists the Tesla Wall Connector for $550. However if one buys a Tesla then a Mobile Connector is included with the vehicle. Am told you now have to order the adapter pigtail to match the outlet, whether NEMA 14-50R or one of the common dryer outlets.

So no Tesla Wall Connector is needed - or of any use - if you already have a welder outlet?

Just buy an adapter pigtail to go between the car's Mobile Connector (intelligent extension cord) and your welder outlet?

Remember: the faster you charge the battery the quicker it will lose capacity. Avoid the fast chargers unless absolutely necessary. Also, the harder you cycle the battery the quicker it will lose capacity. An L2 charger set to no more than 80% with a light foot on the accelerator seems to be the best commuter compromise.

Yes, exactly. I believe this is the connector bundled with the car. The description is accurate and inaccurate in saying it is only 1.3kW. Haters spin that to the max ignoring fact.

Gen 2 Mobile Connector Bundle

The Gen 2 Mobile Connector Bundle allows you to plug into any standard 110v household outlet to begin charging. Features: Max power output of 1.3kW Charging speeds between 2-3 miles of range per hour Includes: 1x Mobile Connector - 20’ cable 1x NEMA 5-15 Adapter 1x storage bag

The bundle only includes the NEMA 5-15 pigtail, hence 1.3kW. Other pigtails bring it up to 32A.

Gen 2 NEMA Adapters

Use a variety of household outlets to charge your Tesla with a Gen 2 NEMA Adapter. Simply attach the appropriate adapter to your Mobile Connector, plug into the corresponding outlet and begin charging. Adapter Max Distance Gained Per Hour of Charge Model S Model 3 Model X Model Y 5-15 3...

Yes but you are splitting hairs over a 9.6kW rate on a 60-100kWh battery.

And just what exactly 80% is is not an industry accepted definition.

Tesla thinks they know what rates are “safe” for Supercharging. We don’t know their definition of safe. They changed the definition for my 2013 S. It will still start at 115kW if SOC is under 40 miles. Tapers off much quicker than it used to. Charge from 40 to 140 now takes 35 minutes. Plus another 30 to get to 200. Takes twice as long as it did before they updated the firmware in my car. Haven’t used it for a long trip since 2019. Burn gasoline instead.

Charges just as fast at home as it ever did.

A truck of a different kind. Not an EV yet but too cool to pass up.

That's what we were taught many years ago.

Really?!?!?

(re: faster battery charge rate increases wear)

But “back then” they were talking about 0.5C, 1.0C, and rates up to 5C. Where C = battery amp-hour capacity / hour.

1C is charging a 1Ah battery at 1A.

My 85 kWh Tesla on 9.6 kW at home is 0.113C, trickle charging by old time rules.

115 kW at Superchargers is still only 1.35C which is only held a few minutes. Quickly drops to 70 kW and keeps falling. Even “many years ago” 1C was considered to be a conservative fast charge rate so long as cell warming was monitored. Today most all battery packs (cellphone, power tools, computer, etc) contain a thermistor for the charger to monitor warming.

This sounds like the kind of land to tie up with solar.
