Solar street light parts are mainly composed of solar panels, batteries, light sources and so on. Because the solar street light is installed in the outdoor, so maintenance is particularly important, especially the battery.
The maintenance of the battery is mainly two avoidance of a control
Two avoid: avoid over-discharge, avoid over-charging
Over-discharge: the deeper the depth of over-discharge, the number of charge and discharge cycles, that is, the shorter the service life, because over-discharge will allow the battery pressure rise, resulting in the reversibility of the positive and negative active material received destruction, electrolyte synthesis, negative lithium buildup, resistance will also increase, even if the charge can only partially recover, and its capacity will be significantly decayed, and will be directly scrapped.
Overcharge: overcharge is the battery charging current is greater than the battery can withstand the current, this overcharge will be converted into heat and let the battery temperature rise, long-term this is easy to cause "thermal runaway", so that the battery capacity is reduced and deformation, and there is an explosion, extinguishing the hidden danger, so we must avoid battery overcharge, in strict accordance with the rules to Provide the voltage value of charging, and do a good job of overcharging maintenance.
A control refers to the control of the ambient temperature of the battery.
Ambient temperature whether too high or too low is also affected by the battery capacity, shorten its service life, first in the battery selection as far as possible to choose lithium batteries, rather than colloidal batteries, lithium batteries, whether it is cold or heat resistance performance are better.
If the battery is buried in the open, to be buried deeper, at least in the center of 40 centimeters, on the one hand, to reduce the impact of temperature, on the other hand, can also avoid being flooded to prevent the impact of water on the battery.
Solar street light battery maintenance must pay extra attention to the over-release is not desirable, likewise, overcharge is not, must pay attention to the solar street light battery two avoid a control.
