Summary: When an energy storage system (ESS) operates in cold conditions, the power and capacity of the battery decrease, and an appropriate battery thermal management strategy (BTMS) is crucial to prevent driving range loss. This study evaluated the trade-off between ESS heating performance enhancement and additional energy consumption. Three BTMSs combined with a secondary heat pump were suggested and analyzed: self-heating, active heating, and heat recovery. The results showed that active heating significantly improved the driving range, while heat recovery reduced the state-of-charge decrease. Battery preheating with the heat pump consumed less power compared to conventional electric heater preheating.

Summary: A hybrid PV/T collector/evaporator was designed and a hybrid system named PV-SAHP/GHP was proposed. Outdoor experiments were conducted to compare the operating characteristics of different modes. The results showed that the GHP-PV/T mode had satisfactory energy-saving effect while the PV-SAHP mode met the temperature demand but had unsatisfactory energy conservation effect. It is recommended to operate the GHP-PV/T mode during intense radiation and the PV-SAHP mode otherwise to balance the thermal performance and energy-saving benefits.

Summary: This study focuses on improving the driving range of electric vehicles (EVs) by using CO2 heat pumps instead of PTC heaters. The research found that frost might lead to a rapid decrease in driving range. To address this issue, a new global performance improvement control method was proposed, which could enhance the driving range by up to 10%. It is recommended to implement this method in regions with low temperatures and high humidity.

Summary: The vehicle thermal management system is a limiting factor for electric vehicle range and battery life. Tesla's waste heat recovery (WHR) thermal management system, the 'Octovalve', significantly reduces energy consumption and battery load during warm-up, but at the cost of overall warm-up time.

Summary: Introducing battery electric vehicles quickly to the market can lead to errors and recalls, which can be avoided by simulating BEVs in an integrated manner. By developing a drivetrain model integrated with cabin, battery, and power electronics models, key system-level outputs are obtained to identify simple energy-conscious actions and quantify energy savings. The integrated model is validated at both component and system levels.

Summary: This article focuses on the thermodynamic concept of exergy, which evaluates the quality of energy and its irreversibilities in machines. It presents simulations of passenger vehicles to understand the exergy destruction in internal combustion engine vehicles (ICEVs) and battery electric vehicles (BEVs), considering different energy mixes. The results show that BEVs have a higher exergy efficiency compared to ICEVs, but EVs in Europe produce more GHG than ethanol-fueled ICE vehicles in Brazil.

Summary: In this study, an optimized fuzzy proportional-integral-differential (Fuzzy PID) algorithm is proposed for a rapid temperature control system in automotive batteries. The algorithm is used to build an intelligent thermal management system with temperature feedback mechanism, employing switchable thermoelectric (TE) devices that offer both heating and cooling capabilities. The battery pack temperature is quickly regulated with the assistance of liquid cooling optimization. Experimental results demonstrate a significant reduction in temperature control time compared to traditional liquid cooling methods.
