Comparison between the ICE, HV, and EV
ICE HV EV
Efficiency Converts 20% of the energy stored in gasoline to power the vehicle
Converts 40%, of the energy stored in gasoline to power the vehicle.
Converts 75% of the chemical energy from the batteries to power the wheels
Speed (average top speed)
198 km per hour (km/hr)
176 km/hr 48-152 km/hr
Acceleration (on average)
0-96 km/hr in 8.4 seconds
0-96 km/hr in 6-7 seconds
0-96 km/hr in 4-6 seconds
Mileage Can go over 480 km before refueling. Typically get 8.37 kmper liter
Typically get 20.29 to 25.36 km per liter
Can only go about 160 to 320 km beforerecharging

Comparison between the ICE, HV, and EV
ICE HV EV
Maintenance • Wheels/tires • Engine • Fuel/gas• Bodywork/paint• Electrical• Lights• Dash/instrument warning lights
Same as ICE. Does not require as much maintenance because it does not use a gasoline engine. No requirements to take it to the Department of Environmental Quality for an emissions inspection
Cost (on average) 456,400 THB to 554,200 THB
619,400 THB to 815,000 THB
Extensive range, 195,600 THB to 3,260,000 THB

Advantages and Disadvantages of the EV
Advantages Disadvantages
Fuel can be harnessed from any source of electricity, which is available in most homes and businesses.
Limited in the distance that can be driven before the complete failure of the battery.
It reduces hydrocarbon and carbon monoxide, responsible for many environmental problems, by 98%.
Accessories, such as air conditioning and radios drain the battery.
Also reduces pollution. Heavier car due to the electric motors, batteries, chargers, and controllers.
Does not produce emissions. Important in urban cities, where cleaner air is much needed.
More expensive because of cost of the parts.

EV Charging Level 1
Input : normal voltage and low current and low power
Recharge : 8-14 hrs. to fully recharge.
Advantage : Easy to charge with household outlet Disadvantage : Long time charging
![Page 31: Electric Vehicle Technology: Present and Future · Electric Vehicle Technology: Present and Future Dr. Surin Khomfoi Associate Professor in EE.

Input: normal voltage medium current and medium power
Recharge: 4-8 hrs. to fully recharge
Advantage : Charging Speed.: Charger will found in common place (eg. House, public parking, employment setting)
Disadvantage : Charging time increasing in cold weather.: Heat from charging will decrease battery life
EV Charging Level 2

Impacts of fast charging station
Requires a bigger amount of power capacity from the supplying electrical grid.
Needs more supplies from medium voltage (MV) grid.
Needs to be constructed alongside motorways in a similar way than the gasoline stations exist today.
The extra load caused by the chargers might overload the grid components and/or cause voltage quality issues when the voltage drop is higher than permitted.
The most serious issue is the overloading of the secondary cable connecting the LV mains of the twin stations and the MV / LV transformer supplying these stations.
