METHOD FOR CALCULATING RESIDUAL CAPACITY OF SODIUM-SULFUR BATTERY

摘要

If residual capacity (Qr) is found by the following expression (1), the residual capacity of a sodium-sulfur battery can be correctly and accurately calculated even if the sodium-sulfur battery is applied to the fluctuation compensation use of the power generated by a natural energy generator. Qr = 100 × (1 - (Qu/(Qa - Qsf))) ??? (1) Qu: Usage capacity Qa: Product capacity Qsf: Residual capacity of final year Qsf = f1 (Cef) ??? (2) f1 (Cef): Transform function to find the residual capacity (Qsf) of the final year on the basis of an equivalent cycle (Cef) of the final year
