Aiming to the issue of charging difficulty and capacity fading for lithium-ion battery at low temperature, this study proposes a preheating strategy using variable-frequency pulse.
Using high-frequency AC to charge or discharge LIB can effectively address the issue of battery aging due to voltage imbalances. The AC heating strategy provides a feasible solution for rapidly heating lithium batteries at low temperatures, which is particularly significant for promoting and advancing electric vehicle adoption in cold regions.
Abstract: In electric vehicles (EVs) and other applications, lithium-ion batteries experience variable load profiles with frequencies up to several kilohertz, as caused by power electronics. It is crucial to know if certain frequencies accelerate battery degradation and should be avoided.
This new finding may help us to reduce the costs of products with complex battery systems, such as EVs. In electric vehicles (EVs) and other applications, lithium-ion batteries experience variable load profiles with frequencies up to several kilohertz, as caused by power electronics.
Abstract: The performance capability envelope of a variable-frequency, permanent-magnet synchronous motor drive with field weakening is dependent upon the product of maximum current and direct-axis inductance.
This applies in particular for EV batteries with an expected lifetime of more than ten years. This study investigates the influence of alternating current (ac) profiles on the lifetime of lithium-ion batteries. High-energy battery cells were tested for more than 1500 equivalent full cycles to practically check the influence of current ripples.
