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!

Computing Hardware

CPU

Central Processing Unit - the main chip in a computer responsible for processing data

GPU

Graphics Processing Unit - some computers contain a processor specifically made for rendering graphics

MCU

The Media Control Unit is the big touchscreen in the middle of the dashboard, and the computer that drives it. The car’s various radios, and all the entertainment and drive-related visualizations are routed through here. You may come across some numbers attached to MCU that specify the hardware version.

MCU1

MCU1 refers to Tesla's first Media Control Unit hardware which was used in Model S and Model X vehicles until March 2018

MCU2

This is Tesla's second general Media Control Unit hardware. It was used in Model S and Model X cars after March 2018. The Model 3 and Model Y started with MCU2 and later transitioned to MCU3 in late 2021. Vehicles with MCU1 can be upgraded to MCU2. MCU2 has the Intel Atom processor.

MCU3

This is Tesla's third and latest MCU hardware. It contains AMD Ryzen's chip, making it much faster than MCU2. For the Model S and Model X it also features a dedicated GPU that will be used for high quality games that rival the PS5 and Xbox Series X. There is no official word from Tesla yet, but MCU2 does not appear to be upgradeable to MCU3.

HW1

Hardware 1 refers to Tesla's original hardware for Autopilot. It was supplied by MobileEye and was only available on the Model S and Model X.

HW2

Around October 2016 Tesla transitioned to their own hardware with version 2.0. This was also only available for the Model S and Model X.

HW2.5

Hardware 2.5 was available in the Model 3 and the Model S and Model X around July 2017.

HW3.0

Tesla eventually released hardware 3.0 in April 2019, which features much faster processors. Owners who bought the FSD package (not the subscription) and had hardware 2.5 are given a free upgrade to hardware 3.0.

ECU

The Electronic Control Unit is the hardware in a vehicle used to control various driving functions.

eMMC

Embedded Multi Media Card is flash storage that is used to store certain information.

An Integrated Circuit, is a chip that is integrated onto a circuit board. This could could refer to the Instrument Cluster on a Model S or Model X.

PCB

Printed Circuit Board used in electronic systems.

Driver Assistance System

DAS

Driver Assistance System, in Tesla's case this would be Autopilot

AP

Autopilot is the term that allows Tesla's to perform some level of self-driving. All Teslas today include basic Autopilot that allows the car to use TACC (Traffic-Aware Cruise Control) and Autosteer.

EAP

Enhanced Autopilot is a package that is a subset of FSD. Tesla offered it for a number of years, but it no longer offers it.

Enhanced Autopilot included features such as TACC (Traffic-Aware Cruise Control), Autosteer, Smart Summon, Autopark, automatic lane changes and more. It does not include as much as the FSD package, which allows the car to also navigate on city streets.

FSD

Full Self-Driving. Refers to the package that currently, in beta form, allows Teslas to navigate many more streets and scenarios by itself (with an alert and engaged driver on standby). In Europe and Asia FSD is still limited, but cars with the FSD package are ready to go from a hardware perspective as soon as the regulations allow.

TACC

Traffic-Aware Cruise Control - All Teslas today compare standard with TACC.

These are the Tesla acronyms and abbreviations you’ll encounter most often. Which ones are new to you? Have you come across any others?

UX

UX is the User Experience of a piece of software.

OTA

OTA stands for Over-The-Air, referencing Tesla's ability to download car updates over Wi-Fi or in some cases using the vehicle's cellular data.

Single Stack

A technology stack refers to the technologies used to build a system. A single-stack refers to using the same technologies for multiple applications, instead of having separate technology stacks for each one.

FUD

FUD stands for Fear, Uncertainty, and Doubt and is sometimes used when someone is spreading misinformation to cast fear

Batteries

LFP

This is referring to the battery chemistry in the car’s high voltage pack, specifically the chemical symbols for Lithium (L), Iron (F) and Phosphate (P is actually for Phosphorus on its own, but PO₄³⁻ doesn’t have the same ring to it). Tesla started shifting some of its shorter-range cars (the SR MYs and M3s) to LFP in 2021, away from battery chemistry involving Nickel and Cobalt.

Even if you’re not a chemist, it’s still worth knowing which battery chemistry you have. It is recommended to keep LFP battery charge limit at 100%, unlike the previous Li-ion batteries that are stressed out if charged fully too often.

4680

Staying with the high voltage battery, 4680 refers to the newer battery technology that is being phased in at Giga Berlin, Giga Texas and Giga Shanghai. These batteries offer efficiency, range and cost improvements over the previous, smaller batteries. The numbers come from the dimensions of each individual cell: 46 x 80mm.

Cybertruck to be waterproof and serve as a boat briefly, may also appear in Cyberpunk 2077

Cybertruck may appear in Cyberpunk 2077 game

Cyberpunk

Cybertruck deliveries will start next year, but if you can't wait that long, you may want to head for Night City. Cyberpunk 2077 has teased that the highly anticipated vehicle in the real world may appear in the popular video game. But, if that's not enough, Elon Musk announced another exciting and unique feature for the futuristic-looking truck - it will be waterproof.

Let's start with the floating Cybertruck, which should not be a shock to anyone following the Tesla CEO. He bought the Lotus Esprit that James Bond used to jump off a pier and transform into a submarine in The Spy Who Loved Me. He purchased the movie prop for just under $1 million in 2013 and told USA Today, "I was disappointed to learn that it can't actually transform. What I'm going to do is upgrade it with a Tesla electric powertrain and try to make it transform for real."

In 2016 he tweeted that the Model S "floats well enough to be a boat," but he did not recommend trying it. Now he has claimed the Cybertruck could be used as a boat — briefly. Musk tweeted: Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes & even seas that aren't too choppy.

In a later tweet, he gave some idea of the distance he has in mind: Needs be able to get from Starbase to South Padre Island, which requires crossing the channel.

Twitter user @Erdayastronaut shed some light on why Musk would be singling out that area and distance. The tweet reads: "One of SpaceX's biggest problems is attracting talent to work at Starbase, which is extremely remote. South Padre is an awesome place to live, but it's almost an hour drive to Starbase despite being only 5 miles from Starbase because of the shipping channel." A quick check of Google Maps demonstrates what the user is describing.

South Padre is only five minutes from Starbase if you cross the channel

Google

Musk's tweet also caught the attention of the Washington State Department of Natural Resources. Officials there seem to be a little concerned about the wording. The official account tweeted: Our derelict vessel crews are begging you to understand that anything that "serves briefly as a boat" should not be used as a boat.

CD Projekt RED also noticed Musk's tweet, and the makers of Cyberpunk used the opportunity to show two concepts of the Cybertruck as it would appear in Night City. Musk and Cyberpunk have had an ongoing relationship for a few years. Most recently, he demonstrated the power of the onboard computer's gaming system by playing Cyberpunk in a Tesla. However, CD Projekt RED did not mention if the Cybertruck in Cyberpunk would float.

Cyberpunk 2077 will be playable in the new Model S

Tesla hints at 'Reverse Summon' being available this year

Tesla now mentions 'Park Seek' or what we know as reverse summon on its website

Tesla

Tesla's team of Autopilot engineers is validating significant advancements to Full Self Driving Beta, including parking lot improvements. While Smart Summon and Reverse Summon were not specifically mentioned during the 3.5-hour AI Day 2022 event, parking lots were discussed, and Elon Musk gave a timeline of when enhancements are expected.

Reverse Summon or 'Park Seek' as Tesla appears to be calling it, is the opposite of Smart Summon. Whereas Smart Summon drives to you from a parking spot, users who activate Reverse Summon would have their Tesla drop them off at a location, perhaps closest to the entrance of a mall, and then find a parking spot. This feature was described by Musk on July 1, 2020, when he gave it a two to a four-month timeline.

Ashok Elluswamy, Tesla’s director of the Autopilot program, started the FSD portion of AI Day, saying, “FSD beta software is quite capable of driving the car. It should be able to navigate from parking lot to parking lot, city street driving, stopping for traffic lights and stops signs, negotiating with objects at intersections, making turns and so on.”

Several team members described how FSD has advanced and soon will be an integrated stack, meaning one code base that includes everything the program needs to navigate the car in a parking lot or on a busy highway. Musk is currently using this new stack, “it works quite well for me, but we need to validate it in all kinds of weather, like heavy rain, snow, dust and make sure it is working better than the production stack across a wide range of environments.”

Paril Jain, the Manager of Autopilot Motion Planning, expanded on what else will be included in the integrated stack, “we do expect to also include the parking lot stack as a part of the FSD stack before the end of this year. So, that will basically bring us to you sitting in the car in the parking lot and drive till the end of the parking lot, at a parking spot, before the end of this year.”

It has been previously reported that Reverse Summon would have three different modes to find parking spots that the owner prefers. The methods would include closest to the entrance, nearby a cart return, and the end of the parking lot for those who like to avoid tight spots that cause door dings. Musk said that the integrated stack is on track for release before the end of the year and maybe as early as November.

Tesla has also updated it's website to reflect this news, although no timeframe is given. The Autopilot section of Tesla's site now has a section titled "To your Destination." The description reads "When you arrive at your destination, simply step out at the entrance and your car will enter park seek mode, automatically search for a spot and park itself. A tap on your phone summons it back to you."
