Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a battery charger for direct charging of photovoltaic components. Background Art

[0002] The battery charger in the photovoltaic module usually refers to the solar charge controller, which is mainly used to manage the process of charging the battery from the photovoltaic panel to ensure that the battery is not overcharged or over-discharged during charging, while maximizing the charging efficiency and battery life. These controllers are usually installed between the photovoltaic panel and the battery to monitor and regulate the transmission of current and voltage to protect the battery and other electronic devices from damage.

[0003] The existing direct charging structure of photovoltaic modules is usually used to directly charge or power mobile batteries, electronic products and electrical appliances, which are often used in outdoor work. The photovoltaic panels need to be unfolded and placed under sunlight for power generation. The existing battery chargers are mostly connected to the photovoltaic panels and need to be plugged into the charger with a connecting cable. However, when using photovoltaic modules outdoors, people are usually in the shade, which means that the batteries, electronic products and electrical appliances need to be used in the sun, which makes it inconvenient for people to use batteries and electronic products while charging, reducing the user experience of charging photovoltaic modules with chargers.

[0015] Preferably, the length of the electric wire is three meters, and the clips are provided in two groups, and one group of the clips is flush with the top of the wire reel.

[0016] By adopting the above technical solution, the length of the wire is set to ensure that there is enough wire to extend for use in the shade, and the wire of appropriate length is convenient for winding and collecting inside the photovoltaic panel for use. At the same time, one of the clips is located on the top of the wire reel, which can position the wire on one side of the wire reel to prevent it from falling apart when the length of the wire is extended.

[0017] Preferably, the four edges of the photovoltaic panel are wrapped with aluminum alloy sheet metal strips, and a handle is welded on the top of the photovoltaic panel.
