APP Function Description

1. Charge curve is adjustable :
   These four items are set values for NPB charging CC.CV.FV.TC, which can be modified to meet the actual charging requirements

2. Set the voltage point for restarting the charge after full charging ON/OFF selection: When the restart charging button is in the open state, after the completion of charging, when the battery voltage drops to the restart charging set voltage value, NPB will restart the charging process from the CC stage; This voltage value can be set according to the actual application and must be lower than the FV setting value.

3. 2 or 3 stage charging options: The button here can set 2-stage or 3-stage charging.

4. Intelligent voltage detection charging mode ON/OFF selection: Here, when the button is in the open state, the intelligent voltage detection mode can be turned on, and the charger will detect the battery voltage; For the detailed description of the smart voltage detection mode, please refer to the relevant content of NPB manual Page 36; If it is in the off state, that is, it is in curve charging mode, and the setting of charging parameters takes effect at this time.

5. NFC burning password setting: The password is not set before delivery. The user can set the password by himself.

CANBus address setting: The default communication address is 0x00; Can set the communication address of NPB model, after setting up to 16 devices to support CANBus multi-machine communication,Can set the address 0~15(0x00~0x0F); When the address accumulation function is turned on, the communication address of the NPB model will be accumulated in turn.

7. Return to factory Settings: Click the original preset button to restore the NPB parameters to factory Settings; The burning button is the necessary operation for burning after each parameter setting.
   Note: 1. Please refer to NPB manual page36-42 for detailed function and parameter description.
   2. Intelligent voltage detection is only applicable to lithium batteries with built-in BMS(Battery management system).

Attention:

1. Read and burn parameters can be AC or not, when the AC is powered on burning operation, parameters will not take effect immediately, only power off and restart to take effect.
2. If you forget to burn the password, you can reset the password through the hardware mode to restore the factory Settings, the specific setting method, please refer to the NPB manual Page 36 on restoring the original factory. Settings;
