Accurate battery state of charge (SOC) estimation can contribute to a reasonable charging/discharging strategy for battery management systems (BMSs). It can also prevent severe damage to the battery (pack) caused by over-charging or over-discharging. This work develops a battery SOC estimation method based on a simplified electrochemical model. Simulated validation under dynamic current loads at room...
Accurate prediction of battery's remaining useful life (RUL) is significant for the reliability and the cost of systems. This paper presents a new Particle Filter (PF) framework for lead-acid battery's RUL prediction by incorporating the battery's electrochemical model. An electrochemical model that simulates the charging and discharging of lead-acid battery is introduced. The effectiveness of both...
Accurate battery state of charge (SOC) estimation conduces to establishing an ideal charging and discharging strategy for battery management system (BMS). And it can also prevent serious damage to battery (pack) from over-charging or over-discharging. This paper firstly establishes a simplified mechanistic model for LiFePO4 battery. Parameter identification conditions are originally designed based...
In recent years, Li-ion rechargeable batteries are well liked to be used in BMS (battery management system) of EV (electrical vehicle) and satellite due to various advantages. As battery is aging during the whole life cycles, it is essential to estimate discharge capacity to ensure high performance. This paper presents a discharge capacity estimation model for Li-ion battery based on PF (particle...
