Optimal charging strategy design for lithium-ion batteries considering minimization of temperature rise and energy loss A framework for charging strategy optimization using a physics-based battery model Real-time optimal lithium-ion battery charging based on explicit model predictive control
While multiple charg-ing strategies for single battery cells have been demonstrated recently, the effects, feasibility, and cost of implementing them in battery packs have not been get examined well.
As hinted at above, another benefit of a higher pack voltage is a reduction in the size of the wires needed for the charging cable for a given power output (i.e. charging rate).
An enhanced fast-charging strategy can overcome these limitations. This work proposes a novel fast-charging strategy to charge lithium-ion batteries safely. This strategy contains a voltage-spectrum-based charging current profile that is optimized based on a physics-based battery model and a genetic algorithm.
Subsequently, the intel-ligent charging method benefits both non-feedback-based and feedback-based charging schemes. It is suitable to charge the battery pack considering the battery cells’ balancing and health. However, its control complexity is higher than other lithium-ion battery packs’ charging methods due to its multi-layer control structure.
