Self-protection Analysis Of All In One Solar Street Light
All In One Solar Led Street Light Supplier would like to share Self-protection Analysis Of All In One Solar Street Light
I believe many people know that the energy of municipal LED solar street lamp comes from solar energy, so it is more environmentally friendly in the LED street lamp industry, because it relies on the sunlight in the daytime on the solar cell, the light energy is converted into electric energy and stored in the battery, and then the battery provides power for the LED of the street lamp at night. No matter how convenient and simple the product is, we need to carry out protection.
1. Direct charge protection point voltage
Direct charge is also called quick charge, belongs to the rapid charge, generally is in the battery voltage is low when the large current and relatively high voltage to the battery charge, but, there is a control point, also called the protection point. Direct charge protection point voltage is generally "overcharge protection point" voltage, when charging the battery terminal voltage can not be higher than this protection point, otherwise it will cause overcharge, the battery is damaged.
2. Voltage of even charge control point:
After the direct charging, the battery will be charged and discharged by the controller for a period of time, let its voltage fall naturally, then fall to the "recovery voltage" value, will enter the state of even charge. Equalizing charge, or "equalizing charge". All charge time is unfavorable and too long, it is a few minutes commonly ~ 10 minutes, time setting is too long harmful instead. For a small system with one or two batteries, both charging does not make much sense. So. All In One Solar Street Light controller is generally not set to charge, only two stages.
3. Voltage of charging control point:
Generally, after the completion of charging, the battery is also static for a period of time, so that its terminal voltage fall naturally, when falling to the maintenance voltage "point, it will enter the floating charging state. Similar to small current charging, the battery voltage a low charge on a point, a low charge on a point, a stream to avoid a continuous rise in the battery temperature, which is very good for the battery.
4. Over-discharge protection termination voltage:
Battery discharge can not be lower than the specified value of the national standard. Although battery manufacturers have their own protection parameters, but the back or to draw close to the national standard.
