Integrate the individual models you have created above and simulate the performance of the integrated system. The nature of EV charging is that the amount of current delivered to the battery is regulated by the EV$$s onboard system. You should therefore investigate the behaviour of the charging system at a range of power settings, ranging from $10$ kW to $50$ kW$.$ You should provide results and commentary related to: $1.$ Evaluation of the overall efficiency of the system across the specified range of outputs. $2.$ Analysis of the harmonic content of the input current drawn from the supply. $3.$ Calculation of the power factor of the system. $4.$ Evaluation of the system based on the above and any other relevant factors you wish to consider, to include any recommendations for how the system could be improved.
