The power generation energy of lithium ion solar wall light 97 led is solar panel, which is one of the important components of solar wall light 97 led. Solar wall light 97 led is a high-efficiency solid-state light source based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, it injects holes in the P area and injects into the N area. After the electrons diffuse to the active area, they recombine by radiation to emit photons, which directly convert electrical energy into light energy. Solar wall light 97 led manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar wall light 97 led will become the choice for energy-saving road lighting. During the daytime, sunlight shines on solar panels, converting light energy into electrical energy and storing it in lithium batteries, which are then stored in lithium batteries. Solar wall light 97 led manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, solar wall light 97 led will become the choice for energy-saving road lighting. The battery powers the solar wall light 97 led light source at night. Below, solar wall light 97 led technicians will analyze the main protection modes of lithium battery solar wall light 97 led:

Mode 1. Direct charging protection point voltage:

Direct charging is also called fast charging. This is a fast charge. When the voltage of the lithium battery is low, the lithium battery is usually charged with a high current and relatively Gaodianya battery. However, there is a control point, also called a protection point. The voltage of the direct charge protection point is generally the "super-electric protection point" voltage. When charging, the terminal voltage of the lithium battery cannot be higher than this protection point, otherwise it will cause overcharge and be harmful to the lithium battery.

Mode II, floating charge control point voltage:

Generally, after the equalization is completed, the lithium battery can also be left to stand for a period of time to make its terminal voltage drop naturally. When it drops to the sustaining voltage point, it enters a floating state. Similar to low current charging, the battery voltage is low. Fill it up, fill it at a low point, and then connect it in series to prevent the battery temperature from rising continuously, which is very beneficial for lithium batteries.

Mode 3. Uniform charge control point voltage:

After the direct charging is over, the lithium battery is generally left for a period of time by the charge and discharge controller to make its voltage drop naturally. When it drops to the "recovery voltage" value, it will enter a uniform state of charge. Simultaneous charging, which is "balanced charging". The filling time should not be too long, usually a few minutes to ten minutes. The time setting is too long and harmful. For a small system with two lithium batteries, neither is important. and so. Street solar wall light 97 led controller is generally not fully charged, only two stages.

Mode 4, over-discharge protection termination voltage:

Lithium battery discharge should not be lower than national standards. Although lithium battery manufacturers have their own protection parameters, in the end they must be closer to national standards.

For safety reasons, the overdischarge protection point voltage of 12V lithium battery is usually artificially added with 0.3V as temperature compensation or zero drift correction of the control circuit, so that the overdischarge protection point voltage of 12V battery is 11.10V, and the overdischarge 24V system GE protection The point voltage is 22.20 volts.
