The PC-controlled application board enables designers to easily build their own battery management system. It is controlled by an Atmel ATmega128 controller board via a GUI. Software control of the application board is done via the PC's serial port or USB port.
Features:
The PC acts as operating system with a powerful GUI to demonstrate and evaluate ATA6870, featuring:
BMS board hardware:
- 3 ATA6870 for up to 18 battery cells in a stack
- BMS Board stackable, up to 16 ATA6870
- Includes battery cell emulator for 18 battery cells
- MOSFETs for charge balancing
- Potentiometer to emulate temperature measurement
- Serial gateway to PC for GUI operation
- Power down mode
Presentation mode – in Standard User Panel:
- Real time waveform plot of 6 cells
- On the fly discharge of individual cells
- Selectable over / undervoltage limits
- Cell status of every cell in matrix
- Data logging e.g. excel format
Advanced User Panel mode:
- Register level control of ATA6870
- De-/Activating dischargers
- Power down
- Single ADC / burst readings
- Temperature reading
- CRC check
- Single SPI commands / script mode for SPI command batch
