WHAT IS EV, HEV, PHEV, AC and DC?
Electric cars are already updating and improving.
Since we know that the terms EV, PHEV, BEV, MHEV, which appear especially in electric vehicles, can be encountered in daily life, let's look at these terms:
EV: EV (Electric Vehicle) It is an abbreviation for all electrically driven vehicles. These vehicles are powered by electric motors to provide movement.
ICE: It is the abbreviation for vehicles that run on gasoline, diesel, biofuel and even gas, and refers to the engines we know today.
HEV: Expression used for hybrid engines. In such vehicles, electric propulsion engine or conventional internal combustion engines can provide power by working separately or together. In this type of vehicle, the energy required for the electric batteries is supplied by the vehicle itself by recycling. Such vehicles make a great contribution to fuel economy.
PHEV: These plug-in hybrid electric vehicles differ from HEV model vehicles in that they are rechargeable. These vehicles can be driven by both an electric drive engine and a conventional internal combustion fossil source engine. The difference with standard hybrid vehicles is that their batteries can be charged with an external power source. Models that can be used like a normal hybrid vehicle when the batteries are empty can only be used for certain distances with the electric motor when charged.
BEV: The term BEV is used under EV vehicles for electric variants with an internal combustion fossil-sourced engine or powertrain driven only by rechargeable batteries, without a fuel tank. These models need to be connected to a power source in case they need to be charged.
MHEV: (Mild hybrid) In this type of vehicles, the electric motor is used to support the internal combustion fossil sourced engine. Motion cannot be achieved using only an electrically driven motor.
FCEV: It is the expression used for electrically driven vehicles with fuel cells. Since this type of vehicle works with an electric motor, it is considered in the EV class. The electrical energy produced as a result of the contact of the hydrogen element in the fuel cells with the oxygen element is transmitted to the batteries in the vehicle. FCEV cars produce their own energy with a hydrogen engine without the need for an external electrical support.
kW and kWh: One kilowatt is 1000 watts and is a commonly used measure of power in electric vehicles. 1 kW corresponds to approximately 1.34 hp. Electric vehicles consume approximately 15-23 kWh of electrical energy per hundred km. Kw is a measure of engine power in engines, such as hp or hp, and battery capacity in kilowatt-hours (kWh) is like fuel tank capacity in liters.
AC and DC: Used to mean AC Alternating Current and DC direct current. Charging stations for electric vehicles are either AC or DC. While electric vehicles store electrical energy as DC, the current from the grid is always AC. It converts the energy from Alternative to Direct current and directs it to the batteries with the converter in the electrically driven vehicles. For this reason, charging times from home sockets is a very time-consuming process for electric vehicles.
