During the use of solar energy storage lamps, overheating of solar energy storage light battery is a problem that needs attention, which may affect the life of solar energy storage light battery and even cause safety hazards. The following are some effective countermeasures.
First, optimizing the heat dissipation design is the key. In the structural design of solar energy storage lamps, sufficient heat dissipation space should be reserved, such as using a well-ventilated shell to allow air to circulate freely around the solar energy storage light battery and take away the heat. At the same time, heat sinks or thermal conductive silicone can be added to quickly conduct the heat generated by the solar energy storage light battery and reduce the temperature of the solar energy storage light battery. Some high-end solar energy storage lamps are also equipped with small fans to actively enhance air convection and further improve heat dissipation efficiency.
Secondly, reasonably control the charging current and voltage. Excessive charging current and voltage will cause the solar energy storage light battery to heat up more, so make sure that the solar charge controller can accurately adjust the charging parameters to match the specifications and characteristics of the solar energy storage light battery. When the solar energy storage light battery is close to full, gradually reduce the charging current and use trickle charging mode to avoid overheating caused by overcharging. Also, check and calibrate the charge controller regularly to ensure that it works properly.
In addition, choose a suitable use environment. Avoid installing solar energy storage lights in high-temperature areas with direct sunlight and no shielding, such as the metal surface of the roof, and try to choose places with certain shade or good ventilation. In the hot summer, the working hours of solar energy storage lights can be adjusted appropriately, such as reducing the duration of strong light exposure during the day, and using the lower temperature at night to charge and store energy to balance the temperature changes of the solar energy storage light battery.
Finally, strengthen the monitoring and maintenance of the solar energy storage light battery. Install a temperature sensor to monitor the temperature of the solar energy storage light battery in real time. When the temperature exceeds the set threshold, issue an alarm in time and take corresponding measures, such as suspending charging or starting the heat dissipation device. Regularly inspect and maintain the solar energy storage light battery, clean the dust and debris on the surface of the solar energy storage light battery, ensure that the heat dissipation channel is unobstructed, and check whether the connection line of the solar energy storage light battery is loose to avoid additional heat due to poor contact.
Through the comprehensive use of the above-mentioned effective means, the overheating problem of solar energy storage light battery can be effectively solved, the service life of solar energy storage light battery can be extended, the performance and safety of solar energy storage lamps can be improved, and it can play a stable and reliable role in more scenarios.
