Abstract

The invention discloses a hybrid electric storage device used for storing solar energy, which comprises a solar panel. The solar panel is connected with a maximum power tracking module which is connected with a control device and a charging switching module; the charging switching module is connected with a super capacitor bank and a storage battery which are connected in parallel; the super capacitor bank is connected with a DC / DC(Direct Current-Direct Current) power module; the DC / DC power module and the storage battery are connected with a discharging switching module; the discharging switching module and the charging switching module are connected with the control device; and the discharging switching module is connected in series with a load and the solar panel. The hybrid electric storage device adopts the super capacitor bank and the storage battery for hybrid energy storage, and the super capacitor bank and the storage battery form a solar energy storage device, so that the storage battery is protected, the service life of the storage battery is prolonged and the hybrid electric storage device reaches the purposes of making full use of the solar energy, saving energy and protecting the environment.

Description

technical field [0001] The invention relates to a solar energy storage device, in particular to a device for hybridly storing energy by a supercapacitor and a storage battery. Background technique [0002] At present, batteries are widely used as energy modules for yellow flashing lights, flashing lights, movable traffic lights and other equipment with low power consumption and low-voltage power supply for a long time. The battery charge and discharge times are generally only more than 500 times, and the maintenance cost is high. Poor discharge characteristics, easy to damage and so on. [0003] Supercapacitors can solve this problem by replacing batteries. Supercapacitors are between batteries and ordinary capacitors. They have the characteristics of high-current fast charge and discharge of capacitors, and also have the characteristics of energy storage of batteries, and they have a long repeated service life. However, supercapacitor energy storage does not There are m...
