Abstract：A high speed energy equalizer for battery pack based on mixed chopper circuit is proposed in this paper. This unique circuit structure makes the equalizer performance excellent. The energy equilibrium of charging, discharging and static state are realized by different chopper circuits in those battery charging state, discharging state and static state respectively. In order to improve the equilibrium speed and the charging-discharging capacity of battery pack effectively, the different energy equilibrium strategies are adopted in different working states of battery pack. The balanced current is continuous and controllable, the equilibrium circuit is easy to control and implement. The principle of the energy equalizer is analyzed in detail. The experiment platform is set up to carry out the charging and discharging equilibrium experiments for series of lithium-iron phosphate batteries. The experimental results of equilibrium prove that the energy equalizer is available.
