Lead carbon battery

as a new kind of energy storage battery

improves the weakness of leadacid battery that can’t be charged or discharged at high rate.In this paper

the experimental platform using NEWWARE battery test system is set up on the basis of introducing basic operating principle lead carbon battery to perform such experimental test as constant current charging and discharging as well as pulse charging and discharging etc on certain type of lead carbon battery with power at 300 Ah.The second-order equivalent circuit model of this battery is set up by adding a RC parallel structure in the first-order model.According to the experimental data

the parameters of each element of the second order circuit model are calculated by the use of Matlab fit tool so to complete the setup of the simulation circuit model.The output end voltage of the battery for simulating charging and discharging of the battery model is calculated and the actual battery data is compared and correctness of the model is verified.This paper lays foundation for the performance of subsequent series battery.
