The energy storage technology of solar garden lights
is necessary to ensure stable lighting at night or in low light conditions. Its energy storage technology comprehensively uses advanced battery technology, battery management systems, charge controllers and charge management algorithms and other elements. This complete system ensures efficient collection and storage of solar energy and provides a reliable source of electrical energy for night lighting, making solar garden lights an environmentally friendly, efficient and long-lasting outdoor lighting solution.
Battery type: Common solar garden lights use lithium-ion batteries as the main energy storage device. Lithium-ion batteries are the first choice in many applications due to their high energy density, lightweight and long life. Compared with other traditional battery technologies, lithium-ion batteries are superior in energy density and cycle life, providing reliable power storage for solar garden lights.
Battery Management System (BMS): In order to ensure the safety and stable performance of the battery pack, the solar garden light is equipped with a battery management system (BMS). BMS monitors and controls the charging and discharging process of the battery, as well as the status of the battery. It is responsible for balancing the charge and discharge of battery cells, preventing overcharge, over-discharge, over-temperature and other problems, and improving the overall performance and life of the battery pack.
Charge Controller: The charge controller is an important bridge between the solar panel and the battery pack. It monitors the output of the solar panels and adjusts the current and voltage through sophisticated control algorithms to ensure the battery pack is optimally charged. Charge controllers often feature maximum power point tracking (MPPT) to maximize solar collection efficiency.
Charging management algorithm: The intelligent charging management algorithm in the energy storage system is the key to optimizing the charging process. These algorithms use data from light and temperature sensors to dynamically adjust charging rates to ensure efficient charging of the battery pack in varying environmental conditions. This helps maximize the use of solar energy resources and improve energy efficiency.
Self-discharge rate control: In order to reduce energy loss, the energy storage system of modern solar garden lights is committed to reducing the self-discharge rate of the battery. The self-discharge rate of a battery is the rate at which the battery discharges itself without a load connected. By using advanced battery technology and reasonable battery management, the self-discharge rate of modern battery packs has been effectively controlled, ensuring long-term storage of electrical energy.
