EV Charger Using Modified DAB Converter

There has been an increase in demand for electric vehicles in recent times, and this demand is expected to continue. However, the most serious flaw with EVs will be the time it takes for a battery to be charged by a charger. Therefore, to mitigate this problem, a DC fast charger (also known as an off-board charger) has been introduced to the automotive industry to remedy this issue. There is going to be a great deal of novelty in this project when a 35 KW DC off-board charger is presented with great functionality. In the following material, one can comprehend what components must be included to guarantee that the charger is relatively less expensive with excellent efficiency. The charger consists of three stages: (a) AC/DC converter (b) DC/DC converter (c) Battery controller. Later in the article, these stages are explained in more detail. A lithium-ion battery with a predetermined SOC and nominal voltage is taken into consideration. One can examine how the SOC and voltage of the battery are raised by looking at a simulink block of the entire closed-loop charger.
