ELECTRIC VEHICLE BATTERY CHARGING SYSTEM

Abstract

Every day, battery technology advances, and the pace of battery utilization rises. Battery usage will rise, especially as electric vehicles become more common. In general, battery based systems are made up of a large number of battery cells. In systems with multiple battery cells, it is critical to ensure that the batteries can be charged and drained in the same amount in order to maximize total energy efficiency and extend battery life.The design is done in such a way that it detects the amount of charge stored in the battery and alters the charging voltage accordingly. Several safety precautions have been built into the design to protect both the battery and the charger. PROTEUS software was used to simulate the situation. The simulation results reveal that the design system charges the batteries efficiently and effectively. The model of the proposed paper is such that it is possible to increase or decrease the output voltage by reducing the duty cycle through variables. Since our lithium ion battery is 12 volts, we need to charge 20 percent more than the input voltage, so we have 14.5 outputs. The Voltage graph is shown in Figure 5.4. The y-axis shows the voltage values and the x-axis shows the simulation time values. The graph shows that the value of voltage rises straight up from 0.1 time point to 14.5 volt. So we can see from the graph that the output value of voltage is 14.5 volt. The current graph is shown in Figure 5.3. The y-axis shows the current values and the x-axis shows the simulation time values. The graph shows that the value of current is slightly curved upwards from 0.1 time point to 0.96 ampere. So we can see from the graph that the output value of current is 0.96 ampere. The value of the output current is less than 0.9 to 1 ampere. Every day, battery technology advances, and the pace of battery utilization rises. Battery usage will rise, especially as electric vehicles become more common.
