How to prolong xingxian in actual application make the battery solar street lamps

Solar street light system, the battery provided the highest cost, its service life is the shortest at the same time, the length of the service life of the battery has become the most important factor of solar street light system used. Therefore, we must reasonable use battery, has extended its

in the solar street light system, the highest cost of battery, the shortest service life. The service life of the battery has become one of the most important factors in the solar street light system used. Therefore, we must reasonable use of battery and prolong its service life. In the practical application of how to extend the service life of the battery solar street lamps? 1, the reasonable calculation of battery capacity before installing solar street light, we must design the battery capacity of solar street lamps. According to the system requirements, parameters such as night lighting time, the local climate conditions and the number of rainy days. , we should calculate the required capacity battery. The type of battery capacity choose not too small or too large. Battery capacity is very small, often excessive discharge, capacity is very large, often without charge, and always in a state of power cuts. Should firmly to avoid improper battery capacity design can lead to serious loss and excessive discharge batteries, which can lead to change inside the battery, will affect the service life of the battery. Therefore, reasonable calculation required capacity battery is the premise of guarantee the battery life. 2, the service life of batteries to cut off the battery discharge voltage control to the depth of discharge. For 50% of the service life of the battery discharge depth than the battery discharge depth is 100% longer. The shorter the discharge depth is larger, the service life of the battery. In order to reasonably control the battery discharge voltage, discharge voltage of battery solar street lamps general control in 11. 2 to 11. Between 5 v, which is helpful to control the battery discharge depth, prolong the service life of the battery. 3, the service life of the battery cell temperature control is also closely related with temperature. Industry experience is generally thought that, compared with 25 ℃, environment temperature rise every 10 ℃, half will shorten the life of the battery. Low temperature has no effect on the service life of the battery, but will affect the effective capacity of the battery. Therefore, in order to battery to provide a more ideal working environment is particularly important. Battery deep underground, can effectively solve the problem of the temperature of the battery. Study found that in certain depth below the surface, because of the existence of geothermal temperature affected by ambient temperature change is small, when ambient temperature is higher, the temperature is lower than the ambient temperature below the surface, and when the outside temperature is low, the surface temperature is higher than the ambient temperature under. Because of the summer sun too hot, winter cold temperature is too low, can affect the service life of the battery solar street lamps, should try to avoid the battery on the solar energy light pole body. 4, pay attention to waterproof battery shell itself has waterproof function. At the same time, the design of solar battery waterproof wire also can prevent water from entering the wires. However, if the battery in water for a long time, the service life of the battery will still be affected. 5, pay attention to monitor the battery solar street lamps voltage when the solar street light for a few days not bright, check the battery voltage. If the voltage is too low, lower than the control by the discharge voltage, and less than 10. 8 volts, the serious battery discharge. In this case, the system should be inspected carefully, see if solar panels to work properly, the controller if there is any problem. If no problem, other parts should be remove the lamp line. Solar panels should be under the control of the controller with 5 - 7 sunny electricity to recharge the battery. Test battery voltage. If the voltage is normal, the cord should be connected to normal use. Don't let the battery in the absence of supervision to death, because the battery voltage is too low. The battery will not be charged, its service life will be affected.
