“…In addition, the battery is a lithium iron phosphate battery (LFP), using lithium iron phosphate (LiFePO 4 ) as the cathode material and a graphitic carbon electrode with a metallic backing as the anode. The methodology explained in the work of A. Broatch et al was followed to determine all parameters of the equivalent circuit [39]. Figure 6 shows the curves of the open circuit voltage V OC during charging and discharging as a function of state of charge (SOC).…”

The potential of e-bus transportation to improve air quality and reduce noise pollution in cities is significant. In order to improve efficiency and extend the useful life of these vehicles, there is a growing need to investigate improvements for the thermal management system of electric city buses. In electric vehicles, there are several systems whose thermal behaviors need to be regulated, such as batteries, electric machines, power electronics, air conditioning, and cabin. In this study, a 0D/1D model of an electric city bus is developed that integrates all sub-models of the powertrain, auxiliaries, and thermal management system. This model is used to evaluate different configurations and thermal management strategies of the electric urban bus by simulating public transport driving cycles in Valencia, Spain, under winter conditions. First, the original thermal–hydraulic circuit of the bus was modified, resulting in an improvement in the battery energy consumption with savings of 11.4% taking advantage of the heat produced in the electric motors to heat the battery. Then, the original PTC heating system of the bus was compared with a proposed heat pump system in terms of battery power consumption. The heat pump system achieved an energy savings of 3.9% compared to the PTC heating system.

“…It has been proven that engine thermal state plays a major role on its performance [137]. In this sense, provided that the engine efficiency (and potentially emissions) are strongly affected by the engine thermal state, the impact of including this variable in the energy management strategy was evaluated.…”
