**5. Results and Discussion**

The experimental results of battery and HVAC heating performances for the integrated system with serial and parallel circuits are comprehensively discussed in this section. Battery and HVAC heating performances of the integrated system with parallel circuit are discussed in Sections 5.1 and 5.2 elaborates the battery and HVAC heating performances of the integrated system with serial circuit. The comparison of integrated system with serial and parallel circuits for battery and HVAC heating performances is presented in Section 5.3. Section 5.4 discusses the results of ANN model for prediction of battery and HVAC heating performances in the case of an integrated system with serial and parallel circuits.
