Solar street light battery life extension technique

Solar green development is growing stronger day by day, because the solar energy resources, is a lot of people also because of the sun and survival, is life, so how to increase the service life of battery? The life of the battery solar street lamps mainly and the depth of discharge dense

solar green development is growing stronger day by day, because the solar energy resources are a lot of, people also because of the sun and survival, is life, so how to increase the service life of battery?

the life of the battery solar street lamps mainly is closely related to the depth of discharge. Such as solar street light discharge above 80%, and the battery charge and discharge times is more than 300 times, but if can be 60% charge and discharge frequency can reach 800 times, 20% discharge depth is poor poor cycle count nearly three times.

to extend battery life skills solar street lamps are as follows:

1, preventing overcharge

the life of the battery solar street lamps and performance is closely related to the heat accumulation of internal, charging to put some control, to achieve the necessary skills.

2, prevent charging less than

and overcharge on the contrary, under charge is mainly caused by charging voltage setting is low or too low. Or the rack system.

3, discharge charge of safe sex

in the process of charging and discharging, cannot appear too high and too low voltage signs.

4, control the environment temperature when the battery temperature, electrolyte activity intensifies, the battery internal resistance is reduced, the float charging flow increase led to increasing conductive component corrosion, reduce life; On the other hand, the activity is abate, electrolyte battery internal resistance increases, the battery's ability to discharge the load is reduced. Therefore, solar street light, the battery temperature monitoring and control and environmental temperature and keep is very necessary.

5, watch the rain into the

battery packaging must be sealed, enough to watch the rain in.

6, timely replace defective batteries

because of the differences of each monomer technology, may by degrees gradually under the floating backward for a long time, so in monitoring unit will have on a regular basis for battery charge management function, in order to activate the backward monomer, make it no longer lag behind. But often lag behind, may become failure batteries.

method above is about to extend battery life, hope for your help.
