Abstract: With the application of the Internet of Things (IoT), smart charging piles, which are important facilities for new energy electric vehicles (NEVs), have become an important part of the smart grid.
Since it takes a long time to charge the battery to the cut-off voltage in the first stage, several studies replace it with specifically optimized terminal voltages as the transition condition to reduce the total charging time , . Customized number of stages are provided in studies , , .
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.
Currently, two solutions are available to decrease the capacity degradation caused by charging batteries at low temperatures: (1) reducing the charging current based on traditional charging schemes ; (2) preheating the battery with external devices before charging .
The study verified that the five-stage constant current charging has the best performances at normal temperatures in terms of charging time and charge efficiency.
