Lithium electricity solar street light has its particularity, energy storage, lithium batteries, active demand is high, more need to make sure the system work stable and reliable, so need special attention in the design. First, the solar battery components solar cell components of the voltage with the temperature of the



lithium electricity solar street lamps 【 Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Has its particularity, energy storage lithium battery 'Lithium battery', is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution. 】 Strong activity and high requirements, more need to make sure the system work stable and reliable, so need special attention in the design.

first, solar cell' Solar cells can effectively absorb solar energy and convert it into a power semiconductor components. 】 Component

the sun battery voltage will decrease with the increase of temperature and component, due to the influence of high temperature, the voltage loss of about 2 v battery components, and the charging process controller on the pressure drop of the diode 0. 7 v, so choose to 18 v working voltage component. Due to the particularity of solar street lights, solar panels, Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 Generally installed on the light pole, for the light pole, are generally not more than 5 meters, the center of gravity is higher, and most of the solar panels are installed using on the top of the street lamp light pole, to enhance the whole set of equipment was, generally choose 1 or more blocks of power of solar panels required for a complete set of system components.

2, lithium electric controller

controller is the key components of the street lamp system ACTS as a manager, it is the biggest function of comprehensive management for lithium battery, good controller shall, according to the characteristics of lithium batteries, setting the key parameters, such as lithium battery overcharge, discharge points, restore points and SOC discharge control and so on. In choosing a street lamp controller' Main street lamp controller is to control the street lamp on and off, open to turn off the lights is a kind of energy saving of science. 】 Restore points, need special attention controller parameters, due to the lithium battery voltage from the restore feature, when the lithium battery in the over discharge state, the controller to cut off the load, then the lithium battery voltage, if some point when the controller parameters Settings, may appear flicker of lamps and lanterns, shorten the life of lithium battery and the light source.

the third, the lithium battery

when choosing the lithium battery, due to the lithium battery activity, must choose normal manufacturer batteries, need to consider the discharge rate
