Led Street Light Housing suppliers will introduce the voltage in different modes:
1. Direct charging protection point voltage: 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 large current. However, there is a control point, also called protection point. The voltage of the direct charge protection point is generally the voltage of the "overcharge protection point". When charging, the voltage of the lithium battery terminal cannot be higher than this protection point, otherwise it will cause overcharging and be harmful to the lithium battery.
2. Floating charge control point voltage: Usually, after the equalization is completed, the lithium battery can also be allowed to stand for a period of time, so that its terminal voltage naturally drops. When it drops to the maintenance voltage point, it enters a floating state. Similar to small current charging, the battery voltage is low. Fill it up, fill it at a low point, and then connect in series to avoid the battery temperature rising continuously, which is very beneficial for lithium batteries.
3. Uniform charging control point voltage: After the charging is completed, the lithium battery is generally placed by the charging and discharging controller for a period of time, so that its voltage naturally drops. When it drops to the "recovery voltage" value, it will enter a uniform state of charge. Charging at the same time, that is, "balanced charging". The filling time should not be too long, generally 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. The led street light controller is generally not fully charged, only two stages.
4. Over-discharge protection termination voltage: Lithium battery discharge should not be lower than national standards. Although lithium battery manufacturers also have their own protection parameters, they must eventually 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 the 12V battery is 11.10V, and the overdischarge 24V system GE protection The point voltage is 22.20 volts.
