“…As two tunable control inputs of the cooling system, q w and q a represent the coolant and cooling air flow rates, respectively, which can be adjusted by controlling the speed of the coolant pump and cooling fan. The engine thermal dynamics (4) is derived from first principles and it is an improved version of the model presented in [23]. The cooling system parameters are presented in Table I, most of which are based on [23], while the remaining ones are estimated.…”

“…On the other hand, thermostat control strategy (TCS) [12]- [14], power follower control strategy (PFCS) [15]- [17] and electric assist control strategy (EACS) [18]- [20] are the most popular rule-based SCSs. However, it is worth noting that most of these conventional energy management approaches are mainly focusing on the drivetrain optimization, and the power consumption of powertrain cooling system is usually neglected or considered separately [21]- [23].…”

“…As the primary power source of HEVs, the ICE converts around two thirds of chemical energy into waste heat which needs to be removed by the cooling system [23]. The engine cooling system thus also plays an important role in the fuel consumption of HEVs [23]- [25]. Therefore, to improve the overall fuel economy, it is worth to consider the engine cooling system together with the drivetrain in the energy management.…”

In this work, a supervisory control strategy is proposed for parallel hybrid electric vehicles (HEVs). The control strategy is based on the equivalent consumption minimization strategy (ECMS) but it also considers the power consumed by the engine cooling system to optimize the overall fuel economy of the vehicle. To verify its effectiveness, the proposed cooling-sensitive ECMS is implemented on a through-the-road (TTR) HEV, after the mathematical model of the TTR HEV is developed based on power flows, and engine thermal dynamics is also included. Simulations are performed with different drive cycles, and the results show that the cooling-sensitive ECMS is able to improve the fuel economy by 2.7% compared to the baseline ECMS. Furthermore, it is shown that cooling-sensitive ECMS operates in a charge-sustaining manner provided that the equivalence factors are optimally selected.

Due to significant impact of energy consumption of air conditioning system on driving range of electric vehicles, study on air conditioning system of electric vehicles is of great importance. However, the research existing is not comprehensive enough, which is limited to the performance and experimental research of the electric air conditioning components. As for influences of air conditioning systems on electric vehicle, model-based multi-parameter analysis is still a lack. In this paper, a thermal and humidity model of electric vehicles is firstly proposed, followed by control strategy of the air conditioning system. Energy consumption analysis of electric vehicles under different driving and ambient conditions is conducted based on simulation results. Keywords-electric vehicle; thermal and humidity systems; control strategy; energy consumption analysis I. that emitted by the passengers and d Q is the heat emitted by the electronic devices.

Abstract:With the increasing demands for vehicle dynamic performance, economy, safety and comfort, and with ever stricter laws concerning energy conservation and emissions, vehicle power systems are becoming much more complex. To pursue high efficiency and light weight in automobile design, the power system and its vehicle integrated thermal management (VITM) system have attracted widespread attention as the major components of modern vehicle technology. Regarding the internal combustion engine vehicle (ICEV), its integrated thermal management (ITM) mainly contains internal combustion engine (ICE) cooling, turbo-charged cooling, exhaust gas recirculation (EGR) cooling, lubrication cooling and air conditioning (AC) or heat pump (HP). As for electric vehicles (EVs), the ITM mainly includes battery cooling/preheating, electric machines (EM) cooling and AC or HP. With the rational effective and comprehensive control over the mentioned dynamic devices and thermal components, the modern VITM can realize collaborative optimization of multiple thermodynamic processes from the aspect of system integration. Furthermore, the computer-aided calculation and numerical simulation have been the significant design methods, especially for complex VITM. The 1D programming can correlate multi-thermal components and the 3D simulating can develop structuralized and modularized design. Additionally, co-simulations can virtualize simulation of various thermo-hydraulic behaviors under the vehicle transient operational conditions. This article reviews relevant researching work and current advances in the ever broadening field of modern vehicle thermal management (VTM). Based on the systematic summaries of the design methods and applications of ITM, future tasks and proposals are presented. This article aims to promote innovation of ITM, strengthen the precise control and the performance predictable ability, furthermore, to enhance the level of research and development (R&D).
