A three-electrode battery is constructed for study. A low-temperature charging framework is developed. This paper proposes a novel framework for low-temperature fast charging of lithium-ion batteries (LIBs) without lithium plating. The framework includes three key components: modeling, constraints, and strategy design.
Within this framework, a novel low-temperature charging strategy is devised. Notably, this strategy enables intelligent switching between BPC heating and charging while facilitating synergistic optimization of BPC heating parameters and charging current.
These observations collectively suggest that the low-temperature charging strategy proposed in this study is reliable and feasible. Another important validation concerns the absence of lithium plating. Fig. 10 (H) illustrates the results for the graphite negative potential of the three-electrode battery.
These findings underscore the necessity of elevating battery temperature to facilitate rapid charging in low-temperature environments. Since the total charging time is uniform across all strategies, the order of charging speed aligns with the order of charging cut-off SOC.
To enhance the charging efficiency of the battery at low temperatures, heating is imperative. Presently, battery heating methods primarily encompass external heating and internal heating .
Fast charging at lower temperatures (10-20 C) must be done very carefully, as the pressure within a cold cell will rise more quickly during charging, which can cause the cell to release gas through the cell's internal pressure vent (which shortens the life of the battery).
