This paper puts forward a new method to collect internal resistance of Li-ion battery

at the same time

designs a online system which can monitor internal resistances of a great many Li-ion batteries.It gives a specific hardware schematics and software algorithm of the low-power system which is composed of digital signal processor(DSP).After utilizing the phase lock loop circuit and the benchmark resistance compensating technology

the result of test shows that the the accuracy of the system improves evidentl...
