I'm seeing a few acronyms in these forums that I don't recognize:

AV - ?
PEV - same as PHEV?

Sorry if this is posted elsewhere!

No attempt to create an exhaustive lexicon of forum acronyms will ever be complete, as Jack rather humorously pointed out above ;) ...but here's my first-draft attempt. (I hope Gooki does not object to me repeating what he's already posted; a single list is more user-friendly than several different lists.)

(Sadly, this list is too long to fit into a single post. AAAAARGH! :mad: o_O :()

EV Forum Acronyms: A-L

4WD -- four wheel drive

ABS -- 1. automatic braking system; 2. anti-lock braking system

A/C -- air conditioner (the term "HVAC" is preferred, to avoid confusion with "AC" for Alternating Current)

ACC -- Adaptive Cruise Control

ADA -- Automobile Dealers Association

AP -- Autopilot (Tesla's suite of driver assist/ semi-self-driving features)

AV -- autonomous vehicle (a self-driving vehicle)

AWD -- all-wheel drive

CARB -- California Air Resources Board (the "clean air agency" in the government of California)

CCS -- Combined Charging System (an EV DC (direct current) fast-charging protocol)

Cd -- coefficient of drag (aerodynamic drag on a car is figured as ACd, or (frontal) area x Cd. Cd alone is not an adequate indication of drag force, altho it is often misused as if it is.)

CHAdeMO -- (an EV DC (direct current) fast-charging protocol. Literally "CHArge de MOve", a Japanese play on words. "O cha demo ikaga desuka" translates as "How about a cup of tea?", referring to the time it would take to charge a car)

CO2 -- carbon dioxide

DC -- 1. Direct Current (electricity, as opposed to AC (alternating current)); 2. (Tesla) Destination Charger (a DCFC with lower power level than a Tesla Supercharger)

DCFC -- direct current fast-charger (a powerful type of EV charger, providing DC (Direct Current) electricity directly to the battery pack; more powerful than is generally found in home installations)

DOE -- U.S. Department of Energy

EAP -- Enhanced Autopilot (enhanced version of Tesla's Autopilot suite of driver-assist/ semi-self-driving features)

EPA -- (U.S.) Environmental Protection Agency

EREV -- extended range electric vehicle (a longer-ranged PHEV such as the Chevy Volt or the Honda Clarity PHEV)

EVSE -- Electric Vehicle Supply Equipment (an offboard EV charger)

FCEV -- fuel cell electric vehicle

FCV -- fuel cell vehicle (= FCEV)

FSD -- full self-driving (an aspirational option which can (or formerly could) be purchased for Tesla cars, altho it won't be functional until some unknown future date)

FUD -- Fear, Uncertainty, and Doubt (Wikipedia defines FUD thus: "Fear, uncertainty and doubt (often shortened to FUD) is a disinformation strategy used in sales, marketing, public relations, politics, cults, and propaganda. FUD is generally a strategy to influence perception by disseminating negative and dubious or false information and a manifestation of the appeal to fear." Please note that accusing someone of posting FUD is more or less the equivalent of accusing them of trolling. Our forum moderator, Domenick, gets annoyed when I call someone a FUDster, so best to avoid that.)

FWD -- 1. front wheel drive; 2. falcon wing doors (Tesla Model X only)

GF (or Gf) -- (a Tesla) Gigafactory

GF1, GF2, GF3 -- (GF1 = the first Gigafactory, in Nevada, now designated Gigafactory 1; GF2 = Tesla's solar panel factory, in Buffalo, NY; GF3 = China (Shanghai) Gigafactory)

HEV -- hybrid electric vehicle (usually refers to a "mild hybrid"; a non-plug-in hybrid)

HUD -- head up display

HV -- high voltage

HVAC -- heating, ventilation, and air conditioning (the climate control system in a vehicle or building)

HW1, HW2, HW3 -- (refers to hardware versions of Tesla's Autopilot; see AP)

ICE -- internal combustion engine

ICEd (or ICED) -- (an invented term indicating an ICEV occupying an EV charging stall)

ICEV -- internal combustion engine vehicle

IIHS -- Insurance Institute for Highway Safety (for safety ratings)

IP -- intellectual property (i.e., patents and trade secrets)

J1772 -- (a type of EV charging plug)

kW -- kilowatt (1000 watts. A unit of power, not to be confused with...)

kWh -- kilowatt-hour (a unit of energy. Please note the abbreviation "W" (Watt) is always capitalized; "kw" and "kwh" are incorrect.)

L1 -- Level 1 (EVSE, around 10-12A @ 120V AC (common wall outlet). ~4 miles/hour charge rate.)

L2 -- Level 2 (EVSE, Around 32-50A @ 240V AC (dryer outlet). ~25 miles/hour charge rate.)

L3 -- Level 3 (An older, now outmoded term for a DCFC)

LA -- lead-acid (battery type)

LHD -- left-hand drive

LI (or li-ion) -- lithium ion (a specific type of battery chemistry)

LR (or LRM3) -- long range (the Tesla Model 3 with the largest ("Long Range") battery pack size)
