| Abstract: | A new method was proposed to solve the issue that service life of energy storage sys tem in ordinary leadacid battery solar LED streetlights was short. In this method, the battery charging and discharging process was controlled using super capacitors hysteresis voltage compar ison method and taking lithium iron phosphate batteries as energy storage system innovatively. The simulation results of control part in lithium iron phosphate battery solar LED streetlights re vealed that the method could store disturbance signal energy into the super capacitor when the light intensity was low and unstable and then charged the battery, finally improve the energy effi ciency and service life of solar LED streetlights. |
