Allocative efficiency of high-power Li-ion batteries from automotive mode (AM) to storage mode (SM)

We investigated a two-phase model from AM to SM, and seven 60 Ah batteries with different compositions were tested under various conditions. Data Envelopment Analysis (DEA) was used to evaluate the best shift point from AM to SM. The experiment was affected by six factors: AM/SM capacity decay, price per kWh, electrical conductance, total kWh generated, and SOH%. Considering all conditions and a price sensitivity analysis from 2009 to 2022, the battery was used in a 1:1 ratio (time in AM to time in SM) to maximize its value.
