Method for determining state of charge of lead battery based on fixed correlation between no-load voltage and state of charge |
摘要 |
Regular measurements of on-load voltage U1 and current I1 are made and values for the no-load voltage U0 derived using the algorithm :- U1 = U0 + R*I1 + 1/C Idt where R is a resistance value and C a capacitance. Then with a group of the measured voltages and currents the parameters U0,R and C are varied in such a manner that the sum of the square of the error variation between the values of U1 derived above and the values measured U(t1) are minimized
