“…The HVB and PE module thermal management loops are circuits designed to actively control the operating temperatures of the HVB and PE modules by utilizing a chiller and a radiator. These circuits use a mixed coolant (ratio of water to ethylene glycol = 50:50) as the working fluid, which has been reported to achieve stable and efficient cooling performance under various climatic conditions [29,30].…”

With an increase in global warming, battery electric vehicles (BEVs), which are environmentally friendly, have been rapidly commercialized to replace conventional vehicles with internal combustion engines. Unlike traditional internal combustion engine vehicles, the powertrain system of BEVs operates with high efficiency, resulting in lower heat generation. This poses a challenge for cabin heating under low-temperature conditions. Conversely, under high-temperature conditions, the operating temperature of a high-voltage battery (HVB) is lower than the ambient air temperature, which makes cooling through ambient air challenging. To overcome these challenges, in this study, we proposed an integrated thermal management system (ITMS) based on a heat pump system capable of stable thermal management under diverse climatic conditions. Furthermore, to assess the ability of the proposed ITMS to perform thermal management under various climatic conditions, we integrated a detailed powertrain system model incorporating BEV specifications and the proposed ITMS model based on the heat pump system. The ITMS model was evaluated under high-load-driving conditions, specifically the HWFET scenario, demonstrating its capability to perform stable thermal management not only under high-temperature conditions, such as at 36 °C, but also under low-temperature conditions, such as at −10 °C, through the designated thermal management modes.

“…A passive air cooling system is not efficient for BTMS. In an active air cooling system, additional components are required like a fan, blower, and duct to circulate working fluid effectively [51]. Due to low heat capacity and thermal conductivity, the air-based cooling system may not be efficient in maintaining the battery in a safe operating temperature range.…”

Lithium-ion batteries are frequently utilized in electric vehicles because of their high energy density and prolonged cycle life. Maintaining the right temperature range is crucial since lithium-ion batteries' performance and lifespan are highly sensitive to temperature. This study discusses a practical battery heat control system in this setting. The phenomenon of heat generation and significant thermal problems with lithium-ion batteries are reviewed in this work. The studies on various battery thermal management systems (BTMS) are then thoroughly analysed and arranged into groups based on thermal cycle possibilities. Direct refrigerant two-phase cooling, second-loop liquid cooling, and cabin air cooling are all components of the BTMS. Phase change material cooling, heat pipe cooling, and thermoelectric element cooling are all future parts of the BTMS. The maximum temperature and maximum temperature differential of the batteries are examined for each BTMS, and a suitable BTMS that addresses the drawbacks of each system is discussed. Finally, a novel BTMS is suggested as a practical thermal management solution for lithium-ion batteries with high energy density.

Summary Electric vehicle thermal management system (EVTMS) is a promising method to solve cabin thermal comfort and electronics waste heat. In this paper, an integrated EVTMS combining heat pump, battery cooling, and motor waste heat recovery was proposed. EVTMS performance tests were firstly carried out in the environment chamber with variations of refrigerant charge, electronic expansion valve (EXV) opening, compressor speed, environmental temperature, and waste heat amount. Moreover, the comprehensive energy, exergy, and thermo‐economy analyses for EVTMS were performed based on the experimental results. The results demonstrate that the optimum refrigerant charge for baseline EVTMS is 810 g, and the optimum EXV opening is in the range of 70% to 90%. Accordingly, the percentage of cooling capacity reduction (PCCR) and the percentage of waste heat recovery (PWHR) are in the range of 26.3% to 32.1% and 18.73% to 45.17%, respectively. The exergy destruction ratio of the scroll compressor and external heat exchanger is more than 80%. With the utilization of the proposed EVTMS, the operation cost per hundred kilometers for heating mode is decreased 20.83% compared with that of positive temperature coefficient heaters.
