Note the details of the battery in the use of solar street light fixtures.
Solar street light fixtures are the most common solar products in our daily life. The battery is one of the main pieces of equipment for solar lamps. It exists to preserve the energy converted from sunlight and convert it into light energy at night to serve our daily lives. Therefore, the quality of the battery and the specification and attention to detail determine the service life of the solar street light fixture.
The maintenance-free lead-acid battery component in solar street light fixtures is very important. It is also known as a valve-regulated sealed lead-acid battery. It has safety and reliability and is not afraid of vibration, low water loss, low self-discharge rate, and good low-temperature startup performance. Of course, the service life of solar street light fixtures is generally comparative, but many friends have responded that batteries often fail, so what are the prevention methods? Here are a few ways to share with you, I believe it will help a lot of friends.
1, solar street light fixtures to prevent excessive discharge
The depth of discharge of the battery is closely related to the number of charge and discharge cycles designed by the battery at that time. Generally, the charge and discharge cycle of the lithium battery is twice or three times that of the ordinary battery, and its service life is relatively long. An excessive discharge will cause the battery to no longer be activated to its best condition or even scrapped.
2, solar street light fixtures to prevent overcharging
The life and performance of a solar street lamp battery are closely related to the accumulation of heat generated inside it. The heat source inside the battery is mainly generated by the power loss of the internal electrochemical reaction, and the product of the charging voltage and the charging current can be simply seen. In the oxidation reaction, the float charge flow is increased to generate more heat, and during constant voltage charging, the float charge flow increases with temperature, thereby further raising the temperature. The thermal runaway phenomenon is a special phenomenon caused by the structure of the valve-controlled sealed battery. Thermal runaway often causes serious damage, and in serious cases, the battery is scrapped.
In the process of using solar street light fixtures, as long as you pay attention to the above two points, you can effectively prevent damage to the battery and avoid the service life is greatly reduced, resulting in increasing use costs.
