Glossary of Terms
Acronym Definition
AC Alternating Current: The standard type of electricity in homes and the most effective way of powering an EV. In AC circuit the voltage swings between positive and negative meaning current flows in both directions (hence 'alternating')
AFV Alternate Fuel Vehicle A vehicle powered by fuel other than gasoline or diesel. Examples of alternative fuels are electricity, hydrogen, and CNG.
BEV Battery Electric Vehicle: See EV below, An electric vehicle whose electricity is exclusively stored in batteries rather than a fuel cell or generator.
BMS Battery Management System: mini onboard computer to monitor entire battery system and each individual battery. Also may be built into charging system.
CARB California Air Resources Board  California Air Resources Board
CCID Charge Circuit Interrupting Device a safety device that will disable utility power to an EV charger in the event of a loss of isolation is detected.
DC Direct Current: A form of electricity where current only flows in one direction. This is the form of electricity produced by batteries and the most common system used in EV conversions.
DOD Depth of Discharge: A measure of how much energy has been withdrawn from a battery. It is expressed as a percentage of the total battery capacity. For example - if you use 25ah of a 100ah battery, that is running the battery to 25% DOD.
E-Situ Energy Stored At The Site  Renewable energy generated and stored at the site acting as a distributed energy resource and functioning as a vehicle charging station interconnected to the grid
Ebike Electric powered Bike, Cycle, Scooter
ELV Electric Light Vehicle Encompasses Electric Vehicles, powered by battery and motor combination, weighing less than 500 pounds; e.g. ebike, e-scooter, e-moped, e-motorcycle, e-ATV, golf cart,e-velomobile (3wheels)
EREV Extended Range Electric Vehicle an electric vehicle with a rechargeable battery as well as an on-board gas powered generator to recharge the battery for extended mileage.
Eroute  Route that an electric vehicle will travel. Intercity public/private transportation route with recharge station/stop. Note that an E-route may additionally denote a nominally "safe" street or paved thoroughfare. It may optionally be marked with easily seen and high-visibility signage.
Etaxi Electric powered Taxi/Tricycle 
EV Electric Vehicle: usually referring to registered passenger vehicles but can refer to any vehicle that is powered exclusively by an electric drive train.
EVC Electric Vehicle Consultant – A good EVC knows all aspects of obtaining, sizing, delivery, training and roll out of private (single) and public (mass) Motorcycle and EV transportation systems. Including infrastructure and route (Eroute) planning.
EVD Electric Vehicle Driver 
EVITP Electric Vehicle Infrastructure Training Program a not for profit, volunteer, EV Industry collaborative, designed to deliver a structured platform to facilitate training and certification for the installation of Electric Vehicle Supply Equipment (EVSE) across residential, commercial and public markets.
EVSE Electric Vehicle Supply Equipment  the charging equipment used to obtain a charge for an EV or BEV battery system.
FCV Fuel Cell Vehicle: A vehicle powered by a fuel cell, usually hydrogen. This is essentially an electric vehicle but using a liquid to store energy rather than a battery.
GHG Green House Gases A gas that in the atmosphere prevents heat from radiating back into space, and thus warms the earth (the greenhouse effect). Carbon dioxide (CO2) is the most common greenhouse gas. Methane (CH4) is another GHG, and has approximately twenty times the greenhouse effect as CO2 in the atmosphere.
HEV Hybrid Electric Vehicle: A vehicle which is powered by both electricity and another fuel, usually petrol/gas (eg Toyota Prius). This is usually just a more efficient way of using the standard fuel as there is no external source of electricity.
HEV Hybrid Electric Vehicle  A vehicle that combines conventional power production (e.g. an ICE) and an electric motor.
ICE Internal Combustion Engine: the standard way to power a vehicle, this part is removed when converting to an electric car.
J-1772 Standard The North American SAE standard for the design on the Charge Coupler.
KW Kilowatt a measure of power. Power is energy per time.
Level 1 EVSE Level 1 Electric Vehicle Supply Equipment 120 volt Charging Equipment. Can fully charges EV in about 18 hours a PHEV may charge to capacity in six (6) hours.
Level 2 EVSE Level 2 Electric Vehicle Supply Equipment 240 volt Charging Equipment. A faster and preferred way to Charge EVs or BEVs in no more than 8 hours depending on battery and vehicle type.
Level 3 EVSE Level 3 Electric Vehicle Supply Equipment High voltage DC Charging Equipment. Requires three-phase electric service. The fastest way to recharge an EV or BEV to 80 percent capacity
Li-ion Lithium Ion  Or Lithium-ion polymer battery. are a type of rechargeable battery in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and from the cathode to the anode when charged.
LiCoO2 Lithium Cobalt Oxide battery chemistry
LiFePO4 Lithium Iron Phosphate battery chemistry
LiPo Lithium Polymer battery chemistry
N/A Range Anxiety The concern that one does not have enough stored energy in their EV or BEV to reach their destination without having to seek a recharging location.
NCM Nano Crystalline Motor – Conducts energy approx 10 times more efficiently than Iron core motors.
NEV Neighborhood Electric Vehicle. Used for short trips around ones community. Church, School, meeting, etc
NiCd
NiCad
Nickel Cadmium battery chemistry
NiMH Nickel-Metal Hydride battery chemistry
Pb-Acid Lead-Acid battery chemistry
PHEV Plug-in Hybrid Electric Vehicle: A hybrid electric vehicle with a substantial battery pack which is able to be charged by an external source other than its fossil fuel (i.e. plugged into household electricity). These vehicles often have the ability to travel is a 'pure electric mode' without using any conventional fuels.
PWM Pulse Width Modulation: a high-efficiency technique for controlling voltage output in a motor controller.
PZEV Partial Zero Emissions Vehicle PZEVs meet SULEV tailpipe emission standards, have zero evaporative emissions and a 15 year / 150,000 mile warranty. No evaporative emissions means that they have fewer emissions while being driven than a typical gasoline car has while just idling.
RBS Regenerative Braking Systems – An EV with a braking system that uses the braking RPM load to charge the onboard batteries.
SAE Society of Automotive Engineers  a non-profit educational and scientific organization dedicated to advancing automotive technology.
VRLA Valve Regulated Lead Acid 
ZEV Zero Emissions Vehicle ZEVs have zero tailpipe emissions are 98% cleaner than the average new model year vehicle. These include battery electric vehicles and hydrogen fuel cell vehicles.
