Investigation of the integrated fuel cell, battery, and heat pump energy systems

The integration of an advanced fuel cell battery electric vehicle was proposed to extend the driving range, increase overall energy efficiency, and produce additional cabin space heating service for on-board application in winter. adopted heat pump absorbs from during charging discharging scenarios at pump's cold end transfers it supply air heating. A numerical model system developed validated by published experimental results. comprehensive evaluation influence output current, rate, ambient temperature, evaporator coolant inlet temperature refrigerant subcooling degree on Coefficient Performance (COP), outlet Equivalent Effective Battery Capacity (EEBC) were conducted. In addition, this study, a detailed comparison previously existing systems carried out terms COP, capacity, EEBC, operating price order examine advantages system. Results showed that not sensitive but had greatest impact compared other defined independent variables. maximum COP 6.07 could be observed when 32 °C. Although increasing current rate would decrease as well. single cycle running 4-hour period estimated. Compared conventional Electric Vehicle Air Source Heat Pump (EVASHP) Positive Temperature (PTC) heaters, has lowest cost which £10.40per while others are £13.8 £19.2 respectively providing same EEBC capacity. Additionally, payback 10,500 cycles. Overall, study provides potential solution efficient vehicles extremely weather with twice EVASHP 2.8 times PTC both ?20 °C is also 1/3 lower than EVASHP. Meanwhile, 2.3 systems. It can sufficiently range electrical winter eliminate anxiety.
