Portable EV Fast Charger DC-DC Converter
No full textCharging electric vehicles (EVs) with direct current (DC) offers significant advantages over alternating current (AC) charging. One benefit is faster charging speeds due to the DC charger’s ability to deliver a higher voltage directly to the vehicle\u27s battery, bypassing the need for on-board conversion resulting in faster, more efficient charging. Additionally, DC chargers can operate at various charging levels, making them suitable for a range of charging conditions, from quick top-ups to full charging sessions. This flexibility is essential for the ever-growing and diverse needs of EVs and lifestyles, from fast-charging stations along highways to overnight charging at homes. However, one of the common roadblocks seen in EV ownership is running out of charge far from a vehicle charger. That is the problem that OpenRoad, the company sponsoring this research, aims to solve by providing a portable EV fast charger which can fit in the trunk of a car. This thesis revolves around designing and testing the power converter circuit which sits between the portable battery pack and the vehicle. Design, simulation, circuit board development, and testing were performed to create the high-power converter, and while the development is still ongoing, the initial results are a positive sign that the converter will function as the intermediary between the final portable battery pack product and the electric vehicle’s internal battery
