Solar street lamps mainly protected mode

As we know, is the main energy of the solar energy solar street lamps, so it is the most environmentally friendly in the street, because it is the day the sun on the solar cell, convert light energy into electrical energy storage in the battery, again by battery at night for the LED street lamp ( Light emitting diodes) Provide power supply. Below, solar lights solar lighting factory zhongshan technical personnel for you parse solar street lamps mainly protected mode:

model a

straight, straight charge point voltage charger also called quick charger, belong to the quick charge, usually in the low storage battery voltage large current and relatively high voltage of battery charging, but there is a control point, also called guard point. Direct charge point voltage is also commonly & other; The overcharge protection point & throughout; Charging voltage, voltage of the battery cannot be higher than that of the guard point, otherwise it will cause of charging, the battery is damaged.

mode 2, all charge control point voltage:

straight after the charge, the battery is normally charge and discharge controller let stand for a period of time, make its voltage natural fall, the fall & other; Recovery voltage & throughout; Value, will enter the state of charge. All charge, i. e. , & other; Equalizing charge & throughout; 。 All filling time shoulds not be too long, generally for a few minutes to ten minutes, time setting too long harmful. Equipped with a piece of two pieces of small battery system, are filled. So. Solar street lamps controller should generally do not set all, only two phases.

mode 3, floating control point voltage:

generally is all finished, battery was also stand for a period of time, make its voltage across the natural, when the whereabouts to maintain voltage & throughout; O 'clock, I entered a floating state. Is similar to a small current charging, low battery voltage is charged on a bit, low charge on a bit, to the a shares, in order to avoid the battery temperature rising, this is protective for battery.

pattern four, discharge termination voltage protection:

battery discharge can not be lower than the national standard of the specified value. Although battery manufacturers have their own protection parameters, but ultimately want to national standard.

to be on the safe side, the 12 v battery discharge protection point voltage plus 0. 3 v as the zero drift correction of temperature compensation and control circuit, so the 12 v battery discharge protection point voltage is: 11. 10 v, 24 v system put protection point voltage is 22. 20V。

that is zhongshan solar solar lighting lamp factory to provide you with the mainly several kinds of protection mode of solar street lamps, solar lights solar lighting factory zhongshan group focus on manufacturing ten years solar street lamps, high quality, good reputation, trustworthy.
