The main steps in battery thermal management system design follow: Identification of objectives and constraints in design of the battery thermal management system (e.g., dimensions, geometry, orientation, number, heat transfer medium, maximum pressure drop, need for ventilation, and cost).
One of the most challenging barriers to this technology is its operating temperature range which is limited within 15°C–35°C. This review aims to provide a comprehensive overview of recent advancements in battery thermal management systems (BTMS) for electric vehicles and stationary energy storage applications.
In all mobile applications of battery systems, including marine, aviation and road vehicles, thermal management of battery cells is an important factor in vehicle design. The battery thermal management system maintains the battery temperature within the desired operating range. There has been much research on battery thermal management systems.
Fig. 5.1 briefly describes illustratively the thermal behavior of a battery system. Heat generation in a battery is seen to originate from four sources: (i) intercalation and deintercalation of active ions (i.e., entropic heating), (ii) heat of phase change, (iii) overpotentials, and (iv) heat release due to mixing.
In addition, refrigerant-based battery thermal management systems constitute a type of PCM-based battery thermal management system that is capable of removing high heat loads at high C-rate operating conditions compared to air-based and liquid-based battery thermal management systems.
A Battery Thermal Management System, or BTMS, helps to maintain a battery pack at its optimal temperature range of 20 o to 45 o C regardless of ambient temperature. For each vehicle design, the required performance and cycle life of the battery pack will be considered to determine the specific set point for the battery pack temperature.
