Library Description

This library allows user to perform a control of the Balancer 3 Click board and to check the Overvoltage condition status. This click also can be used for power supply with the voltage range from 6V to 8.4V. For more details check documentation.

Key functions:

  • void balancer3_gpioDriverInit( T_BALANCER3_P gpioObj ) - This function initializes GPIO driver.
  • void balancer3_enable_cell_balance( uint8_t state ) - This function allows user to enable or disable Cell Balance (cell mismatch correction circuitry).
  • uint8_t balancer3_check_overvoltage_cond( void ) - This function checks the Overvoltage condition.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes GPIO driver and sets the time interval variable (time_inter) to the 0, which is used for OV condition message logging.
  • Application Task - (code snippet) - Allows user to enter a commands that can enable or disable cell balance and check the overvoltage condition. When OV condition is not detected, the status message will be sent after every 8 seconds. When OV condition is detected, the status message will be sent after every 2 seconds. Press '0' when you want to disable cell balance. Press '1' when you want to enable cell balance. Press '2' when you want to check the OV condition status immediately. Note : The voltage of each cell in a 2-series cell battery pack is compared to an internal reference voltage. If either cell reaches an overvoltage condition, the Balancer 3 click starts a timer that provides a delay proportional to the capacitance on the CD pin, in our example it's about 2 seconds. Upon expiration of the internal timer, the OV condition will be detected. If enabled, the Balancer 3 click performs automatic cell imbalance correction where the two cells are automatically corrected for voltage imbalance by loading the cell with the higher charge voltage with a small balancing current. When the cells are measured to be equal within nominally 0 mV, the load current is removed. It will be re-applied if the imbalance exceeds nominally 30 mV. The cell mismatch correction circuitry is controlled by the user.

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

Rotary B 2 Click is a compact add-on board that allows you to add a precision input knob to your design. This board features the TLC5925, a low-power 16-channel constant-current LED sink driver from Texas Instruments that, combined with a high-quality rotary encoder from ALPS, the EC12D1564402, allows you to add a precision input knob to your design. It also features an LED ring composed of 16 individual blue LEDs that can be used to represent the encoder position more visually.
