For the maintenance of solar street light batteries, you need to pay attention to these 4 points!

December 07, 2022

The development of Solar Street Light is getting better and better. Everyone knows that solar street lights are green and renewable energy, so the tendency to choose solar street lights is relatively large. Not only that, solar street lights are also very popular in rural areas. As long as there is sunlight, they can generate electricity and save people a lot of electricity bills. Who doesn't like such a good product? Speaking of this, we all know that the core of solar street lights is the battery, so how should the battery be maintained?

1. To prevent overcharging

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

2. To prevent insufficient charging

In addition to preventing overcharging, solar cells should also prevent undercharging. Insufficient charging may also be caused by rack system failure or low voltage. Frequent undercharging will result in fewer battery cycles and shorten battery life

3. To prevent over-discharge

The discharge depth of the battery is closely related to the number of charge and discharge cycles (service life) of the battery design. Proportionally speaking, 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, it may cause the battery to be unable to activate to the best state, or even be scrapped at once. In order to prevent the battery from over-discharging, it is necessary to install an additional BMS system in the battery, which can adjust the voltage of the battery and balance the voltage and current between the batteries, so that one will not be full and the other will starve to death.

4. Control the ambient temperature

A particularly high temperature environment will shorten the life of the solar battery by half, so it is very important to control the temperature of the solar battery. The service life of the battery is relatively long in normal temperature weather, but in high temperature weather, the battery will suffer a lot. Pay more attention to the above four points, the battery life of solar street lights will be longer!
