Mild hybrids – Mhev (Mild hybris electric vehicle)

What is a Mhev ? (also known as power-assist hybrids, battery-assisted hybrid vehicles or BAHVs) is not an electric vehicle. Mhev vehicles are generally cars with an internal combustion engine equipped with an electric machine (one motor/generator in a parallel hybrid configuration) allowing the engine to be turned off whenever the car is coasting, braking, or stopped, and then quickly restarted once power is again required. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine (ICE), but mild hybrids do not have an electric-only mode of propulsion.

What are electric vehicles?

-Electric vehicles are battery electric vehicles (BEVs)

-Electric vehicles are plug-in hybrid electric vehicles (PHEVs)

-Electric vehicles are hydrogen  converted to electricity by the fuel cell (FCEVs)

-Electric vehicles are plug-in fuel cell electric vehicles (PFCEVs) that combine features of battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs)

all they use electricity to improve vehicle efficiency and can significantly reduce city pollution by having zero emissions.

Electric – Bev (Battery electric vehicle)

What is a Bev? A battery-powered electric car is an automobile which is propelled by electric motors. Although electric cars often give good acceleration and have generally acceptable top speed, the lower specific energy of production batteries available in 2015 compared with carbon-based fuels means that electric cars need batteries that are a fairly large fraction of the vehicle mass but still often give a relatively low range between charges. Recharging can also take significant lengths of time. For journeys within a single battery charge, rather than long journeys, electric cars are practical forms of transportation and can be recharged overnight.

Electric-PHEV (Plug in hybrid vehicle)

What is a PHEV? A plug-in hybrid electric vehicle is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Compared to conventional hybrid electric vehicles (HEVs), PHEVs have a larger battery pack that can be charged from the power grid, which is also more efficient and can cost less than using only the on-board generator, and also often have a more powerful electric output capable of longer and more frequent EV mode driving, helping to reduce operating costs. A PHEV's battery pack is smaller than all-electric vehicles for the same vehicle weight (due to the necessity to still accommodate its combustion engine and hybrid drivetrain), but has the auxiliary option of switching back to using its gasoline/diesel engine like a conventional HEV if the battery runs low, alleviating range anxiety especially for places that lack sufficient charging infrastructure.

Electric – FCEV (Fuel cell electric vehicle)

What is a FCEV ? A fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as zero-emissions vehicles that emit only water and heat. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. The first commercially produced hydrogen fuel cell automobile, the Hyundai ix35 FCEV, was introduced in 2013, Toyota Mirai followed in 2015 and then Honda entered the market.

Electric – PFCEV (plug in electri vehicle)

What is a PFCEV ? This vehicle is very similar to Fuel Cell Electric Vehicle but has a socket and can be recharged from the grid. Battery likely is significantly larger - comparable to Plug in Hybrid Electric Vehicle. This vehicle type can be used solely on electricity charged by plugging in or solely on electricity generated by fuel cell.

Plug-in fuel cell electric vehicles (PFCEVs) combine features of battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs). With a 40-mile battery electric range (BER), the PFCEV provides unusually efficient driving.  The fuel cell and hydrogen fuel facilitate long range and quick refueling, removing range limitations. With a small battery and fuel cell, the PFCEV maintains weight low and efficiency high.
