Tesla acronyms, abbreviations, terms and what they mean

By Kieran Burgess
Tesla abbreviations and defintions

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.

Breaking Tradition: Tesla Hits the Social Media Advertising Road

By Kevin Armstrong
Model Y Advertising
Model Y Advertising
Tesla

Tesla has prepared us for a slower sales year, but just how slow may be showing up on social media. No, I’m not talking about X, which is where 99% of Tesla news comes from, but social platforms owned by a guy that Elon Musk once wanted to fight.

Tesla advertising has been shown on Mark Zuckerberg's Facebook and Instagram accounts. While Musk has talked about utilizing more conventional advertising for more than a year, Tesla has only sporadically shown up on a few digital avenues; now, it appears to be a full campaign.

The Return to Meta and Zuck

The year 2018 marked a significant moment in Tesla's history when Elon Musk, in a move reflective of his disdain for Facebook amid the Cambridge Analytica scandal, deleted Tesla and SpaceX's Facebook pages, both of which boasted millions of followers. Fast forward six years, Tesla has reinstated its presence on Facebook and launched advertising campaigns across Meta-owned platforms.

Musk is now paying Tesla money to a guy he challenged to a cage match and once joked/threatened to drive by his house and fight him. There are two takeaways here: Meta is a dominant force in online advertising, and Musk is willing to do whatever it takes to advance Tesla’s mission to a sustainable future.

Embracing Traditional Advertising Amidst EV Market Changes

Tesla's advertisements, including ads on Cars.com, which highlight the Model Y, demonstrate the company's adeptness in utilizing Meta's sophisticated targeting capabilities to reach potential customers. Tesla's avoidance of traditional advertising was once heralded as a visionary move, saving the company billions and contributing to its mystique.

However, the electric vehicle landscape has evolved, with early adopters now equipped with their chosen EVs, making it imperative for Tesla and its competitors to reach a broader audience. Tesla's advertising initiatives on Facebook, Instagram, and YouTube reflect this strategic adjustment, aiming to capture the attention of potential buyers beyond its core fanbase.

Despite Elon Musk's historically critical view of advertising and his complex relationship with the social media advertising sphere, Tesla's foray into paid advertisements represents a significant evolution in the company's marketing strategy. This shift acknowledges the necessity of diversified marketing approaches in sustaining growth and expanding market reach in the contemporary automotive landscape.

Tesla's foray into private 5G networking places it in an advantageous position in the automotive and tech industries. This strategic move aligns with the global trend towards adopting private 5G networks, which promise to revolutionize industries with their reliability and speed. Tesla's efforts to develop a private 5G protocol stack that integrates with any cellular infrastructure globally will set new industry standards.

With 5G, Tesla vehicles and Optimus robots will benefit from significantly reduced latency, offering under 5 milliseconds compared to the 60-98 milliseconds of 4G networks. This technological advancement is expected to enhance the functionality and responsiveness of Tesla's products, paving the way for advanced autonomous driving capabilities and efficient robot operations.

Tesla's interest in developing a private 5G network is a logical step. By building an infrastructure that supports the fastest connectivity standards, Tesla is preparing for its vehicles and laying the groundwork for sophisticated robotics applications.
