Balancer 3 Click

Balancer 3 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This application is device for 2-series cell lithium-ion battery.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Balancer3

Example Key Functions

• balancer3_cfg_setup Config Object Initialization function.

void balancer3_cfg_setup ( balancer3_cfg_t *cfg ); 

• balancer3_init Initialization function.

balancer3_init ( balancer3_t *ctx, balancer3_cfg_t *cfg );

• balancer3_enable_cell_balance Cell Balance Enable function.

void balancer3_enable_cell_balance ( balancer3_t *ctx, uint8_t state );

• balancer3_check_overvoltage Overvoltage Condition Check function.

uint8_t balancer3_check_overvoltage ( balancer3_t *ctx );

Application Init

Initializes device coummunication and enables cell balancing.

void application_init ( void )
{
    log_cfg_t log_cfg;
    balancer3_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    balancer3_cfg_setup( &cfg );
    BALANCER3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    balancer3_init( &balancer3, &cfg );
         
    balancer3_enable_cell_balance( &balancer3, BALANCER3_CELL_BALANCE_EN );
    log_printf( &logger, "* Normal operation - Cell balance enabled *\r\n" );
    
    log_info( &logger, " Application Task " );
}

Application Task

Checks if overvoltage is occured and disables cell balancing. If overvoltage doesn't occur it enables cell balancing.

void application_task ( void )
{
    static uint8_t old_ov_state = 0;
    uint8_t ov_state = balancer3_check_overvoltage( &balancer3 );
    if ( old_ov_state != ov_state )
    {
        old_ov_state = ov_state;
        if ( BALANCER3_OV_COND_NOT_DETECTED == ov_state )
        {
            log_printf( &logger, "* Normal operation - Cell balance enabled *\r\n" );
            balancer3_enable_cell_balance( &balancer3, BALANCER3_CELL_BALANCE_EN );
        }
        else
        {
            log_printf( &logger, "* Overvoltage condition - Cell balance disabled * \r\n" );
            balancer3_enable_cell_balance( &balancer3, BALANCER3_CELL_BALANCE_DIS );
        }
    }
    Delay_ms ( 1 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
