Maintenance method of waterproof wall light outdoor wall lamp battery

With the gradual improvement of the application of waterproof wall light outdoor wall lamp in urban roads, road lighting must not only meet the requirements of use and enhance the taste of the city, but also be safe, reliable, durable, provide people with a good travel and living environment, and create social benefits. , Save maintenance costs. Because the waterproof wall light outdoor wall lamp is installed outdoors, maintenance is particularly important. As a very important part of the waterproof wall light outdoor wall lamp, the battery needs to be maintained. What are the maintenance methods for waterproof wall light outdoor wall lamp batteries? The following is the sharing of the editor of Century Sunshine Lighting:

　　 1. Prevent insufficient charging

　　 In addition to preventing overcharging, solar cells must also prevent undercharging. If the charging has been insufficient, it may also be caused by a problem with the rack system or a low voltage. Frequent undercharging will reduce the number of cycles of the battery and shorten the life of the battery.

　　2, to prevent overcharging

The battery life of waterproof wall light outdoor wall lamp is not only dependent on the external maintenance, but also closely related to the internal heat accumulation. If the solar battery is overcharged, the temperature inside the battery will rise step by step, and thermal runaway will occur. The phenomenon. If it is serious, it may greatly shorten the life of the battery, or even make the battery useless. If we want to prevent the battery from overcharging, we must strictly follow the manufacturer's instructions to provide the charging voltage value.

　　 3. To prevent over-discharge

　　The depth of discharge of a battery is closely related to the number of charge and discharge cycles (service life) of the battery design. To make a ratio, if the depth of discharge is 10%, the number of cycles is 10,000, and when the depth of discharge is 70%, the number of cycles is only 500. The greater the depth of discharge, the fewer the number of cycles.

　　 If the over-discharge is serious, the life of the battery will be shorter. If it is serious, the battery may not be able to be activated to a good state, or even be scrapped at once. In order to prevent the battery from over-discharging, it is necessary to install a BMS system in the battery, so that the voltage of the battery can be adjusted, the voltage and current between the batteries can be balanced, and there will be no situation of starving and starving.
