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.
Numerical experiments validate the effectiveness under extreme temperatures. This article presents an integrated control strategy for optimal fast charging and active thermal management of lithium-ion batteries (LiBs) in extreme ambient temperatures, striking a balance between charging speed and battery health.
The lithium battery should first be exposed to test temperatures of 40 °C, 25 °C, 10 °C, −5 °C, and −20 °C for 10 h before being charged with a constant current of 1C to the charging cut-off voltage (4.2 V) and then switching to constant-voltage charging. When the current rate is less than 0.05C, charging should be stopped.
Battery charge performance and aging using the proposed approach are evaluated. Lithium-ion battery fast charging issues have become a main bottleneck of large-scale deployment of electric vehicles. This paper develops a polarization based charging time and temperature rise optimization strategy for lithium-ion batteries.
Second, a polarization based charging time and temperature rise optimization strategy for lithium-ion batteries is proposed to equilibrate charging speed and lifetime. Finally, genetic algorithm (GA) is wielded to search for the optimal charging current trajectories, taking temperature rise constraint and charging time into account.
Lithium-ion batteries have been widely used in electric vehicles and consumer electronics, such as tablets and smartphones . However, charging of lithium-ion batteries in cold environments remains a challenge, facing the problems of prolonged charging time, less charged capacity, and accelerated capacity decay .
