The most critical issue for battery control and management is how to obtain the battery states such as SOC, SOE, SOP, SOT, SOH, and RUL. However, these states cannot be measured directly by sensors and can only be obtained by estimating measurable parameters such as voltage, current, and temperature.
The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
The battery management system is key to the safe operation of the battery system and is often equipped to track operating conditions and monitor the battery system for potential faults . Without real-time, effective fault diagnosis and prognosis methods, a small failure can lead to even serious damage to the battery system .
Future research directions in battery modeling and state estimation can be summarized as follows: (1) Establish fast and reliable state prediction models, and study adaptive parameter estimation and self-learning methods that take into account the environment and aging degree, so as to improve the theory of adaptive estimation.
The dilemma mainly includes: (1) for cells and battery packs, the internal heat mechanism is not clear enough and coupled with other mechanisms, such as aging. (2) for battery thermal management system design, system design is complex and costly, making it difficult to ensure heat transfer efficiency.
