Effects of circuit parameters and initial SOC on heating performance were analyzed. LIBs can be heated from −10 °C to 0 °C in 120 s with little capacity degradation. Unbalanced initial SOCs of the battery packs can improve the heating rate and SUR. Polarization is a major problem for lithium-ion batteries (LIBs) at low temperatures.
Designing a reasonable thermal management scheme based on the temperature variation and temperature field distribution of lithium batteries is urgently needed , but the battery temperature is significantly affected by the current and ambient temperature.
Unbalanced initial SOCs of the battery packs can improve the heating rate and SUR. Polarization is a major problem for lithium-ion batteries (LIBs) at low temperatures. To realize rapid preheating of LIBs at low temperatures, a self-heating strategy based on bidirectional pulse current without external power is proposed.
Schematic of the Lithium-ion battery. Lithium-ion batteries (LIBs) are being intensively studied and universally used as power sources for electric vehicle (EV) applications.
In this paper, a simulation model of a lithium battery with thermal characteristics is established. This thermal model is coupled with a temperature-dependent 2-RC equivalent circuit model to form an electro-thermal model for lithium-ion batteries. The hybrid pulse power characterization test is used to estimate the equivalent circuit parameters.
The heating power is studied for different BPC parameters. A novel non-destructive BPC heating method is developed. Low temperatures seriously affect the performance of lithium-ion batteries. This study proposes a non-destructive low-temperature bidirectional pulse current (BPC) heating method.
