| Abstract: | The test algorithm of parameter identification internal resistance for alternating current (AC) injection model was described. The control core of the scheme was STM8SOO3 embedded micro controller unit(MCU),loading AC in Li-ion battery and collecting real time current, voltage. The discharge curves, internal resistance and other parameters of the Li-ion battery were measured by the paiameter identification algorithm. Compared with the AT526B battery, the relative error of output voltage, discharge capacity for 18650 type Li-ion battery was less than 1%, while the relative enor of internal resistance was 3.11%. |
