As an energy storage component, the battery plays increasingly important role in new energy industry.
Charging and discharging system is the vital part of the application of the battery, but the charge and discharge are
always designed separately and carried by different part in the traditional application. Additionally, most battery
discharge mode and method are always simplified which cannot ensure to meet the demand of power utilization. In
the actual energy storage system, the design of the energy converter, which make the power storage and supply as a
whole and the design of the charge and discharge method, will play an important role in efficient utilization of the
battery system. As a part of the new energy system, the study makes battery and the charging and discharging
system as a whole to store energy, which can store and release electric energy high efficiently according to the
system state and control the bidirectional flow of energy precisely. Using TMS320F2812 as the control core, the
system which integrates charging and discharging with battery monitoring can achieve the bidirectional Buck/Boost
power control. It can achieve three-stage charging and selective discharging of the battery. Due to the influence of
the diode reverse recovery time, current oscillation will appear. In order to eliminate the oscillation, we can set the
circuit to work in critical conduction mode. The experimental result shows that the system can achieve the charging
and discharging control of lead-acid battery and increase the battery life time further.
Key words: Buck/Boost, critical conduction mode control strategy, DSP, lead-acid battery, three-stage charge, ,
