Volt, Electric, and Hybrid Car Acronyms.

  1. ABS - Antilock Brake System. Prevents the wheels from locking up (ceasing rotation) when a driver steps hard on the brakes and avoids uncontrolled skidding.
  2. ACC - Automatic Cruise Control. Sometimes called TACC - Traffic Aware Cruise Control
  3. AER - All-Electric Range mode. The vehicle is driven with motor only (with the combustion engine off), range is the total miles driven electrically before the engine turns on for the first time.
  4. AGM - Absorbed Glass Mat battery (the 12 volt battery), sometimes called a gel battery. See VRLA battery: http://en.wikipedia.org/wiki/VRLA_battery
  5. Ah - Amp Hours. The measure of battery capacity as in "1800 mAh".
  6. APM - Accessory Power Module. A 12V DC-DC converter.
  7. AT - Automatic Transmission
  8. AT-PZEV - Advanced Technology Partial Zero Emission Vehicle. For California HOV. Also many upper east coast states adopt CA standards.
  9. BEV - Battery Electric Vehicle. Example: the Nissan Leaf. No backup power supply, when the battery is empty, the car stops.
  10. BMS - Battery Management System. Monitors the battery voltages, temps, charging etc.
  11. BTCPITW - Battery Too Cold, Plug In To Warm. Displays during extremely cold temperatures, when the vehicle will not start until the high voltage battery is warm enough to conduct electricity. Protects the battery. If very cold, but not extreme cold, the car will start but you may see a Propulsion Reduced message until the battery is warmed by normal car operation.
  12. BURPING - After a full battery charge, disconnecting and reconnecting (after waiting a minute) the charge cord for a bit of extra charging. Unlike a baby, nothing spills on your shoulder.
  13. CARB - California Air Resources Board. Established 1967 by then-governor Ronald Reagan. A department within the cabinet-level California Environmental Protection Agency. Other states are permitted to follow CARB standards. Establishes standards for low and zero emission vehicles: LEV, ULEV, SULEV, PZEV, AT PZEV, ZEV.
  14. CAVUTO - Cloddish, Asinine, Vapid, Uninformed, Thick-Headed & Out to lunch. An idiot. As in, “Look at that CAVUTO with his gasoline powered teleprompter”. See http://mediamatters.org/blog/201108230004
  15. CD - Charge Depleting mode. An operating mode in which the energy storage state-of-charge (SOC) may fluctuate but, on average, decreases while the vehicle is driven.
  16. CDH - Blended or Charge-Depleting Hybrid mode. An operating mode in which the energy storage SOC decreases, on average, while the vehicle is driven; the engine is used occasionally to support power requests.
  17. CEL - Check Engine Light. A malfunction indicator light, a.k.a. MIL.
  18. CHMSL - Center High Mounted Stop Light
  19. CS - Charge-Sustaining mode. An operating mode in which the energy storage State of Charge may fluctuate but, on average, is maintained at a certain level while the vehicle is driven. This is the common operating mode of commercial Hybrid Electric Vehicles.
  20. DIC - Driver Information Center (Instrument cluster example where you see your current MPH.)
  21. DOD - Depth of Discharge. The amount of usable battery available to drive the car : http://nissan-leaf.net/2010/08/04/le...-of-discharge/Also see SOC.
  22. DRL - Daytime Running Lamps.

  24. EDR - Event Data Recorder. A device in some automobiles used to record information related to vehicle crashes or accidents.
  25. EMM - Engine Maintenance Mode. Runs the engine to keep it in good working condition after approximately six weeks of no or very limited engine operation.
  26. ERDTBT - Engine Running Due To Battery Temperature. The engine will kick on to power the car while the battery is warmed after a deep freeze. Once the battery is thawed, it takes over and the ICE shuts off. This action appears to be independent of the Outside Temperature Sensor and relies on the battery's own set of temperature sensors.
  27. ERDTT (also ERDTCT, ERDTLT) - Engine Running Due To Temperature (variations: Engine Running Due To Cold Temperature, Engine Running Due To Low Temperature). Engine Assisted Heating in the owners manual. The engine will kick on for a short time to provide warmth to the cabin's heating system. Depending on Volt model year, this action is triggered by the Outside Temperature Sensor seeing 15°F, or 35°F (MY2013+), 25°F (MY2011/2012). It does not warm the battery, only the cabin.
  28. EREV - Extended Range Electric Vehicle. An electric vehicle that can continue traveling after the battery is depleted. Example: the Volt. Also see REX.
  29. ESC - Electronic Stability Control. A computerized sytem to detect and reduce loss of tire traction (skidding).
  30. EV - Electric Vehicle. A vehicle that is moved by electric motors. The Volt is an EV.
  31. EVER - Electric Vehicle with Extended Range. Fisker's rearrangement of EREV to distinguish its Karma from the Chevy Volt. A distinction without much of a difference.

Ge = gallon of gasoline equivalent = 34.02 kWh.
MPGe = miles traveled by expending 34.02 kWh of energy, equal to the energy content of one gallon of gasoline.

Alternatively:

MPGe = possibly the most confusing measurement unit ever invented by committee.

I've been wondering about this for a while. I was going to make a post asking this question. Just stumbled on to this thread today. Thanks for the info.

Acronyms are tool for people to appear smart and exclude people by confusion and disorientation.

They are the bane of business, and in the end save no time.

CAVUTO is not a Acronym... By the way (NOT-BTW! :))

One I'm seeing a lot that is becoming confusing is FFE. Traditionally it stood for Ford Focus Electric. However, it can also now stand for Ford Fusion Energi. So you really have to look at the context on that one.

OR! The person creating the context could just type it out. :)

Different battery types might be useful too.

LMO = lithium manganese oxide
NMC = lithium nickel manganese cobalt
LTO = lithium titanate

What is RPT ? It's to the left of radio off on button on a 2013 volt with nab.
I wonder if your owner's manual would explain dash controls and how they work?
