A review of novel thermal management systems for batteries

Abstract

SummaryIn the recent years, significant developments in the electric batteries have made them one of the most promising storage technologies for electrical energy. Among the various rechargeable batteries that are developed, lithium ion batteries stand out due to their capability of storing more energy per unit mass, low discharge rate, low weight, and lack of a memory effect. The advantages that batteries offer have promoted the development of the electric and hybrid electric vehicles. However, during charging and discharging processes, batteries generate heat. If this heat is not removed quickly, the battery temperature will rise, resulting in safety concerns and performance degradation. Thermal management systems are developed to maintain the temperature of the battery within the optimum operation range. This review paper focuses on novel battery thermal management systems (BTMSs). Air, liquid, phase change material, and pool-based BTMSs are considered. Air-based thermal management systems are discussed first. Liquid cooling systems and phase change-based systems are discussed subsequently, and then the recently proposed evaporating pool-based thermal management system is considered.

An updated review of energy storage systems: Classification and applications in distributed generation power systems incorporating renewable energy resources

“…The large demand of Li‐ion batteries is because these are very portable and economical which make them suitable for small electronic devices, but the cost increases significantly for large‐power applications owing to the requirement of distinctive packaging and protection . These batteries suffer from poor heat handling capability and thereby thermal instability at high temperatures besides premature aging …”

A review on research status and key technologies of battery thermal management and its enhanced safety

“…Given the high energy density and extended cycle life, lithium‐ion battery is regarded as the ideal power source of the green‐energy vehicle, especially the electric vehicle . The battery life span and working performance can be adversely affected by temperature, especially when it is out of the optimum temperature range .…”

“…In recent years, the use of lithium‐ion batteries has become widespread since they fulfill end user requirements. Lithium‐ion batteries own several advantages over other battery types as (1) having lower mass densities, (2) not having memory effects, (3) lower self‐discharge rates, higher energy density, and being in smaller sizes compared with others . Therefore, lithium‐ion battery cells are heavily favored in portable electronics (laptops, tablets, and cell phones), electric vehicles (EVs), and hybrid electric vehicles (HEVs).…”
