摘要	To improve the charging efficiency of lithium iron array batteries, a novel limiting voltage pulsed constant current equalizing charger is designed and developed, which is based on the time division multiplexing (TDM) technology. The proposed charger consists of high speed pulsed generator model, TDM signal generator model, constant current model and protection model, et al. In addition, the charger is combining with high speed analog proportional-integral-derivative (PID) feedback, which has the ability of regulating charging currents in each battery independently. In terms of software, digital discrete Ziegler-Nichols proportion-integral-derivative (PID) control algorithm is utilized, which can reduce the un-identity of battery characteristic, obtain the equalizing charging and enhance its using life much longer. Utilizing the proposed charger, a charging experiment is performed on four lithium ion batteries with the capability of 24V/24AH. The experimental results show that the stability of drive current is better than 410-5A, linearity of the power system is better than 99.97%, which can guarantee the quick charge of lithium iron array batteries.
