This paper has designed a temperature-aware charging strategy with adaptive current sequences to improve the charging performance of lithium-ion batteries in cold environments. An integrated battery model with time-varying parameters is established to reveal the relationship among battery electrical, thermal, and aging features.
Design of a novel adaptive framework for battery charging in cold environments. Impacts of battery temperatures on model parameters are experimentally identified. Number of charging stages and the associated transition conditions are adaptive. A trade-off between charging time and battery aging at low temperatures is achieved.
At extremely low temperature conditions, the electrolyte might even freeze, leading to discharge failure [19, 20]. Charging at low temperatures can lead to undesirable anode lithium plating [21, 22], and hence a reduced battery lifespan.
Charging at low temperatures can lead to undesirable anode lithium plating [21, 22], and hence a reduced battery lifespan. For instance, operating in low-temperatures can reduce the lifetime of lithium-ion batteries to around 90–140 cycles . In addition, operating at low temperatures can also lead to capacity losses.
