Floating charge indicator is a power supply (discharge) mode of battery pack.
< br >
The system connects the battery pack with the power line in parallel to the load circuit, and its voltage is generally constant, only slightly higher than the terminal voltage of the battery pack.
< br >
A small amount of current provided by the power line compensates for the loss of the local action of the battery pack, so that it can often be kept in a satisfied state of charge without overcharging.

Floating characteristics:
< br >
A battery pack is a charging device that provides a floating charge stream to the battery pack in addition to supplying power to the conventional load.
< br >
This mode of operation is called the full floating charging mode, referred to as floating charging operation.
< br >
Therefore, the battery pack can be charged and discharged with the fluctuation of the power line voltage.
< br >
When the load is light and the power line voltage is high, the battery pack charges. When the load is heavy or the power supply is unexpectedly interrupted, the battery pack discharges to share part or all of the load.
< br >
In this way, the battery pack plays a role in voltage regulation and is in a standby state.
Power indicator: The AC power supply is switched on.
Charge indicator: indicates that the battery is being charged.
Floating charge indicator: indicates that the battery is about to be full, and charges at constant voltage. The reason why the charger indicator light is always green when the electric tricycle is charging is that the model is wrong and the voltage is not matched. The charger's polarity protection may be broken. The line is dead. Output line false break.
This is unusual. The charger is broken and the output voltage is much lower than the normal no-load voltage. The reason why the indicator light is not on after the electric car charger is plugged in is:
1, the power supply line is broken, check the plug to the charger circuit, test the charger is normal 220V;
2, rectifier circuit failure;
3, the circuit fuse in the charger is broken;
4,305V voltage is abnormal, the power management chip is damaged;
5, the charger has no output.
