Tesla acronyms, abbreviations, terms and what they mean

WTTWOT! Or in plain English, Welcome To The World of Tesla! As you dip your toe in researching your much anticipated Tesla purchase online, or pull up for your first ever supercharge and strike up a conversation with the owner in the next (but one) stall, you’ll soon come across a new language: TWAs (Tesla World Acronyms). If you hadn’t stopped here, you might be scrabbling for words to keep up, but luckily you did stop here, and we’ve got you covered. You’ll be aware of some general EV (Electric Vehicle) and ICE (Internal Combustion Engine) abbreviations already, but if you want to know your SCs from your SuCs and more Tesla-specific TWAs, you’re in the right place.

Charging

CCS

Combined Charging System - a newer charging port that has become the standard in Europe and other markets

CHAdeMO

CHArge de MOve, a popular DC charging standard

J1772

AC power charging connection standard by SAE

MC

Tesla's Mobile Connector that was previously included with vehicles. Older generations are called the Universal Mobile Connector (UMC)

HPWC

Tesla's wall connector used to be called the High Power Wall Connector, but it is now just referred to as the Wall Connector

SC

OK, so this abbreviation comes up a lot in the Tesla community. And there are three possibilities with SC, so context is everything. SC can refer to the Service Center, which you hopefully won’t need. It can also refer to a SuperCharger in the Tesla network. Finally, it is occasionally used to refer to SolarCity, a solar energy company that was acquired by Tesla in 2016.

SuC

You might see this as an abbreviation for a Supercharger that helps to differentiate it from a Service Center.

SOC

State of Charge. The percentage your battery is charged.

PPU

Pay Per Use, for charging either at Superchargers or other public chargers

Electricity & Energy

AC

Alternating Current - the electricity in your house uses alternating current

DC

Direct Current - energy stored in batteries uses direct current

NEC

The National Electrical Code is a common standard for electrical wiring and equipment in the US

NEMA

The National Electrical Manufacturers Association is the largest association of electrical equipment in the US

NEMA 14-50

This common plug is often used to charge EVs and provides a maximum 50 amps of power, however EVs should only use up to 40 amps due to a constant load.

kW

Kilowatt (1000 watts, a unit of electric power)

kWh

Kilowatt-hours on the other hand refers to how much energy has been consumed in total. It is an absolute figure, equivalent to gallons or liters of gas burned in an ICE car.

Wh/mi

Not a Tesla-exclusive term, but an important one for EV owners. Watt-hours per mile is the EV equivalent of MPG, and tells us how much energy is being used per mile. Lower is better.

Regen

Again, an EV term rather than Tesla only, but you’ll see it used a lot in the Tesla community. It’s short for Regenerative Braking, and refers to the re-capture of kinetic energy by the battery when slowing down, or going down a steep hill. Regen is often the biggest thing new Tesla owners notice and have to adapt to. Once you do, there is no going back!

Uber Now Uses Tesla API Data To Show a Range-Based Trip Planner

Uber now has access to Tesla vehicle data that allows it to limit trips within range

Uber

In a monumental move towards the future of ridesharing, Tesla and Uber have unveiled a new feature — a range-based trip planner. This integration allows Tesla drivers to connect their vehicles to the Uber app and schedule rides based on the remaining battery charge of their electric vehicles. This innovation is set to redefine the experience of both drivers and passengers in the ridesharing space.

Bridging Tesla and Uber: The New Age of Ridesharing

First observed by Tesla enthusiast and former Uber driver Sofiaan, this range-based planner enables Tesla owners to accept rides in the Uber app based on their vehicle's current charge. The feature is activated only when users permit it, and once enabled, it assigns rides that can be comfortably completed with the existing battery level, leaving a small buffer to reach a Supercharger.

While introducing this feature marks an exciting leap in integrating electric vehicles into the ridesharing world, it has raised some eyebrows over privacy and data concerns. The new feature requires drivers to allow Uber access to their vehicle's data through the Tesla API. While it may cause some apprehension, this innovation is a significant aid for drivers who may be unsure about their Tesla's range or those experiencing range anxiety.

The Driver's Perspective: The Challenge of Balancing Charge and Availability

Driving for Uber or Lyft with an EV can be challenging. Rideshare drivers need to balance the need to recharge their vehicles with the necessity to remain available for passenger pick-ups. This new range-based planner alleviates some of this stress by intelligently allocating rides based on the remaining battery life. Such a feature could be particularly advantageous for those operating in areas with limited fast-charging infrastructure.

This range-based planner promises to improve the rideshare experience for Tesla drivers. With it, drivers will only be offered rides they can complete with their existing charge. This eliminates the dilemma of declining rides due to insufficient battery life, which could result in a penalty from Uber.

Ridesharing and the Future of Autonomous Vehicles

As we look toward the future, this development prompts larger questions about the ridesharing landscape and the advent of autonomous vehicles. Companies like Tesla, Uber, and Lyft, along with emerging players such as Waymo, Cruise, and Ford's new autonomy division, continue to innovate and compete. With the ongoing shifts towards electric and autonomous vehicles, these new technologies and collaborations will play an essential role in shaping the future of transportation.

This initiative by Tesla and Uber is a vital step toward integrating electric vehicles into the mainstream. As we anticipate the further transformation of ridesharing services, one thing remains clear — the ride toward green transportation is accelerating, and Tesla and Uber are at the forefront of this revolution.

An Early Look at Tesla's 2023.20 Update and Its Features

Tesla is introducing the ability to track your tire mileage in update 2023.20

Preparations are underway for Tesla's next software update, version 2023.20. Although currently in testing, this update has been drawing attention since it was first noticed last week. Considering Tesla's 2023.12 update brought numerous new features, it appears this next may be smaller. However, we now have our first look at some of the features included in Tesla's 2023.20 update.

Ability to Track Tire Mileage

A noteworthy improvement under the upcoming update pertains to tire service tracking. Post-update, vehicle owners can track how many miles have been driven since their last tire service. This feature can prove valuable for monitoring mileage since your last tire rotation, changing to new tires, or switching between season-specific tires.

You or your service center will need to manually reset the counter each time your tires are serviced. You can view the mileage traveled or reset your counter by navigating to Controls > Service.

The official release notes state:

Go to Controls > Service to see how many miles it's been since your last tire service.

When you get your tires rotated, replaced, or swapped, tap 'Reset' to reset the counter.

Furthering Global Reach: Text Size Adjustment

Another feature gaining more ground is text size adjustment. While 'Text Size' was introduced in the 2023.12 update, the ability to adjust the size of the text in the vehicle's UI was limited to select languages. The feature has now been extended to all languages supported by Tesla. This expansion affirms Tesla's commitment to accessibility for its global user base, ensuring a seamless experience across different regions and languages.

While the Text Size feature in update 2023.12 only applied to the Model 3 and Model Y, it's not clear whether update 2023.20 also introduces the feature to the Model S and Model X. Based on Tesla's feature release history, this feature will likely apply to at least the redesigned Model S and Model X in the futre, but it's not immediately clear whether that is happening with this update.

The release notes for 2023.20 state:

Large text size feature is now available in all supported languages.

To update your settings, go to Controls > Display > Text Size.

Release Date

Although Tesla does not provide release dates for upcoming software updates, we may see update 2023.20 start rolling out in the next week or two. This timing can change if Tesla uncovers issues that need to be addressed before a public release.

2023.12 Update: A Look Back

As we anticipate the rollout of 2023.20, it's worth reflecting on the last major update - 2023.12.1. This update significantly enriched Tesla's features, particularly for Model 3 and Model Y. One standout was steering wheel customization. A long press on the left scroll button revealed a host of adjustable settings and functions.

Moreover, introducing the new search function facilitated more accessible access to controls and settings, along with points of interest that included photos and reviews. The ability to adjust wipers using the steering wheel scroll wheel emerged as a valuable, undocumented feature.

Perhaps one of the most user-friendly updates was the option of Standard or Large text sizes for the touchscreen display, which now applies to all languages under the 2023.20 update.

Other improvements included optional gear chimes for Model 3/Y, the transition of Tesla's Spotify player to a web-based format, enhanced phone call controls, and vision-based speed assist feature expansion. Tesla also broadened Zoom availability to more countries, added writing support for legacy Model S and Model X in China, and continued to make user interface enhancements.

While this is an early look at the upcoming features update 2023.20, it provides a glimpse into Tesla's continuing pursuit of improving user experience and convenience. There may be additional features in this update that are not listed here since not all Tesla features are available for every vehicle or region.

As we wait for the public release, it's evident that Tesla continues to push boundaries in its software development, setting high standards in the electric vehicle market.
