How to improve the reliability of lithium-ion battery packs?
There are many approaches being used to improve the reliability of lithium-ion battery packs (LIBPs). Among them, fault-tolerant technology based on redundant design is an effective method [4, 5]. At the same time, redundant design is accompanied by changes in the structure and layout, which will affect the reliability of battery packs.
What is a reliability optimization method for lithium-ion battery pack?
A novel reliability optimization method for lithium-ion battery pack is proposed. This method combines multiphysics simulation and response surface methodology. Collaborative optimization of redundancy and layout is implemented efficiently. A optimal redundancy scheme with optimal layout of a battery pack is determined.
Do vibration and temperature influence performance in lithium-ion batteries?
However, there has been limited research that combines both, vibration and temperature, to assess the overall performance. The presented review aims to summarise all the past published research which describes the parameters that influence performance in lithium-ion batteries.
What is an automotive lithium-ion battery pack?
An automotive lithium-ion battery pack is a device comprising electrochemical cells interconnected in series or parallel that provide energy to the electric vehicle. The battery pack embraces different systems of interrelated subsystems necessary to meet technical and life requirements according to the applications (Warner, 2015).
Can a lithium-ion battery pack be vibration tested?
However, previous research acknowledges that different vibration tests proposed in standards and regulations for lithium-ion battery packs vary substantially in the levels of energy and frequency range (Kjell and Lang, 2014) so there is still a big challenge to emulate a test that represents the real working condition of electric vehicles.
What are the parameters of a battery?
The state of the battery is mainly defined by two parameters: state of charge (SOC) and, state of health (SOH). Both parameters influence performance in the battery and are dependant on each other (Jossen et al., 1999).
