“…It generally allows a better battery temperature control than air-cooling, especially at higher charging and discharging rates. Direct liquid cooling the cells or battery pack is stored in a fluid environment, whereas in an indirect liquid-cooling system, the coolant is circulated between the battery pack and a heat sink [77]. The efficiency is mostly influenced by fluid flow rate, fluid temperature, flow channel structure and cooling medium.…”

Heat generation and therefore thermal transport plays a critical role in ensuring performance, ageing and safety for lithium-ion batteries (LIB). Increased battery temperature is the most important ageing accelerator. Understanding and managing temperature and ageing for batteries in operation is thus a multiscale challenge, ranging from the micro/nanoscale within the single material layers to large, integrated LIB packs. This paper includes an extended literature survey of experimental studies on commercial cells investigating the capacity and performance degradation of LIB. It compares the degradation behavior in terms of the influence of operating conditions for different chemistries and cell sizes. A simple thermal model for linking some of these parameters together is presented as well. While the temperature appears to have a large impact on ageing acceleration above room temperature during cycling for all studied cells, the effect of SOC and C rate appear to be rather cell dependent.Through the application of new simulations, it is shown that during cell testing, the actual cell temperature can deviate severely from the reported temperature depending on the thermal management during testing and C rate. It is shown, that the battery lifetime reduction at high C rates can be for large parts due to an increase in temperature especially for high energy cells and poor cooling during cycling studies. Measuring and reporting the actual battery (surface) temperature allow for a proper interpretation of results and transferring results from laboratory experiments to real applications.

“…The operating temperature of the battery is considered important because it can discharge power (during startup and acceleration). Temperature and humidity levels greatly affect the performance, safety, and lifetime of battery cells, thus making control of them a major challenge for battery integration into vehicles [21]. In addition, the battery management system (BMS) is essential for battery electric vehicles (BEV) due to the fragility of lithium-ion batteries.…”

The electric vehicle industry is expected to increase from year to year. Electric vehicles used energy stored in battery packs. The battery requires a long energy charge when the energy in the battery runs out. The solution to this energy charging time is a battery swap system. The purpose of this study was to analyze the parameters of the quality requirements for the development of a national standard battery for electric vehicles. The sampling method was carried out by non-probability sampling with a purposive sampling method. Respondents consist of various types of stakeholders who are directly related to electric vehicles so that this approach is expected to be able to answer the needs of the standard parameters of electric vehicle swap batteries in Indonesia. Data were analyzed using descriptive analysis. Based on the research results obtained several parameters, namely the type of battery, battery size and dimensions, security system requirements, communication, protection against electric shock, equipment construction requirements, electromagnetic compatibility, and marking and instructions. It is expected that these parameters can be taken into consideration for inclusion in the Indonesian National Standard governing battery swap in electric vehicles.

“…Air cooling can be obtained in a number of configurations, including forced or natural convection and ambient or conditioned air. Three sources of air can be considered: ambient air, air from the air conditioning system and a dedicated VCC unit [13,131]. In [132], an experimental campaign has been realized to compare the effectiveness of forced or natural convection.…”

Vehicle electrification demands a deep analysis of the thermal problems in order to increase vehicle efficiency and battery life and performance. An efficient thermal management of an electrified vehicle has to involve every system of the vehicle. However, it is not sufficient to optimize the thermal behavior of each subsystem, but thermal management has to be considered at system level to optimize the global performance of the vehicle. The present paper provides an organic review of the current aspects of thermal management from a system engineering perspective. Starting from the definition of the requirements and targets of the thermal management system, each vehicle subsystem is analyzed and related to the whole system. In this framework, problems referring to modeling, simulation and optimization are considered and discussed. The current technological challenges and developments in thermal management are highlighted at vehicle and component levels.
