Mahidol Engineering Research Team Invent an innovative prototype of EV Quick Charger for electric vehicles. It is a fast charging system at home that takes less than 2 hours.
Electric vehicles (EV: Electrical Vehicle) in the global market is growing exponentially. Automakers are increasingly focusing on developing technologies and innovations related to electric vehicles. For Thailand, the National Electric Vehicle Policy Committee Prepare measures to promote the use of electric cars It aims to produce 30% by 2030, which is expected to bring the price of EVs down as much as a combustion engine. with tax measures Establishment of additional charging stations and standard testing centers
Assoc. Prof. Dr. Chakkrit Suthakorn Dean of the Faculty of Engineering Mahidol University said global warming, which many countries are aware of the impact of climate change (Climate Change) that is more severe every year Driving the automotive world to the electric vehicle (EV), with many countries setting goals to switch to electric vehicles faster than before. The trend of using electric cars is increasing continuously. because it saves energy costs reduce pollution in the environment reduce oil imports and jointly create a Low-Carbon Society
The research team of the Faculty of Engineering Mahidol University which consists of Dr. Samnida Phatranun and Ajarn Thanathip Ounon The professors of the Department of Electrical Engineering and the student team are Korawan Yishun and Lalisa Eakvorachat have studied and developed innovative prototypes An alternative fast charging system for electric vehicles (Alternative Design of EV Quick Charger) to shorten the time of charging electric vehicle batteriesfor housing It is designed to suit the needs of electric train users in Thailand. And expect that charging the battery to full takes less time. can be further developed to make it more convenient to use
Dr. Somnida Pattranun Lecturer at Department of Electrical Engineering Faculty of Engineering Mahidol University said the study found that There are not enough electric vehicle charging stations in Thailand. Most of the electric car users are so interested in charging their batteries in their homes with the EV Home Charger device that has a charging time of up to 10 hours. The research team has started a study to develop innovations. An alternative fast charging system for electric vehicles
which consists of Power Converters It is designed to convert alternating current to direct current suitable for direct charging into the lithium-ion battery inside the electric vehicle. by controlling the work ofSolid State Devices Inside the converter in the form of CCCV (Constant Current Constant Voltage) that can help reduce the charging time and usePI Controller To control the current and voltage while charging to suit the lithium-ion battery (Li-ion Battery). how to use The device must be operated with a three-phase power system. The side that is connected to charge the electric vehicle will be the connector.Type2 CCs Type2 Generally, the house is a 1-phase, 15(45) amp system, you have to ask for electricity to change to 3 phase 30(100) amps.
Prosof An alternative fast charging system for electric vehicles (Alternative Design of EV Quick Charger) is to charge the battery withDC power without passing the On Board Charger inside the electric car, makingfast chargingUnlike most EV Home Charger devices on the market that charge using AC power through the On Board Charger inside an electric vehicle. which makes the charging time approximately 6 – 10 hours
fromtest resultsA prototype circuit of an alternative fast charging system for electric vehicles. Able to charge lithium-ion batteries (Li-on batteries) used in small electric cars. It takes less than 2 hours to charge the battery from 0 to 100%. In the future, Thailand will be self-reliant in electric vehicle equipment technology. and develop designs to be suitable for use in residential homes Convenient for continuous use
