USB power protection:
1. When charging multiple batteries, the USB power supply needs to supply a large current. In order to ensure that no USB power is damaged, the NIUP11TA adds USB power protection. When the USB power supply voltage is pulled down to a certain threshold, reduce the charging current to protect the USB power supply. When the USB power supply voltage rises, adjust the charging current to the maximum value.
2. Short circuit protection and 0 volt battery activation:
NIUP11TA can intelligently detect whether the output is short-circuited and indicate an error. The NIUP11TA allows long-term shorts in the output without damaging any circuitry and USB power, and the output is shorted and maintains low power consumption.
The NIUP11TA has a 0-volt battery activation function that determines a 0-volt battery when the short-circuit is detected for the first time after power-on. The horse activates the 0-volt battery, and the 0-volt battery activates and enters the normal charging process. If the 0 volt battery is not activated, it will be judged to be a short circuit and the indicator light will start flashing.
Battery protection:
1. If the battery voltage is higher than 1.35V, the battery is considered to be close to full capacity. After plugging in, it will not be charged, and the indicator light will be extinguished to prevent the battery capacity from dropping due to the memory effect of the nickel-cadmium battery.
2. After the battery is connected, the number of battery packs will be judged. If the voltage is not within the corresponding range, charging will not be performed.
Charging process:
1. Battery insertion detection
When the charger is powered up, it will automatically detect the presence or absence of battery insertion. After detecting the 0-volt battery, it will be activated automatically. When the short-circuit is detected, an error will be indicated. If the number of battery packs is not matched with the circuit, an error will be reported. After the correct battery pack is inserted, normal charging will be performed.
2. Pre-charge
If the battery pack connected to the battery pack is less than 1V, it indicates that the battery is discharged too much. It needs to be activated after a small current is activated to prevent damage to the battery. Pre-charging requires a current of 100 mA and a fast charge when the single cell voltage is greater than 1V.
3. Fast charging
If the battery pack connected to the battery pack is already greater than 1V, it indicates that the battery has passed the precharge threshold and can be quickly charged. Fast charging requires current to be controlled at 250mA. The fast charging process should periodically detect the battery voltage and charging current, and detect the battery voltage -v or 0△V, and jump to make up the charging.
4. make up the charge
Fast charging has been used to charge the battery voltage to 1.3V or higher with a large current. If fast charging is used, the temperature of the battery will rise rapidly. It needs to be changed to a smaller current to make up the charge. At this time, the current is controlled at 200mA. Make up the charging time for 20 minutes, and then jump to trickle charging after the end of the charge.
5. trickle charging
In order to make up for the self-discharge of the battery, it will enter the trickle charge after the end of charging. The trickle charge current is 40mA. After entering the trickle charge, the indicator light has been extinguished. When the user removes the battery, it will enter the next charge cycle.
6. Battery take-out detection
When charging is entered, the system will continue to take the battery removal test. After detecting that the battery is removed, it will enter the next charging cycle.
