TIDA-010990
Pack-level electrochemical impedance spectroscopy (EIS) excitation reference design
TIDA-010990
概覽
This reference design features a bidirectional isolated, multi-port dual active bridge (DAB) DC/DC converter designed for battery pack EIS excitation and active pack balancing. The design can generate a sinusoidal current from 0.04Hz to 2000Hz with up to 10A peak-to-peak amplitude. Additionally, the design supports both constant current (CC) and constant voltage (CV) modes to achieve efficient active pack balancing.
特點
- Bidirectional dual-active-bridge with simple singlephase-shift (SPS) control scheme
- PI + PR control for closed loop control for 0.04hz-2000hz sinusoidal current
- Supports SPI and CAN communication
- Supports up to 104s battery pack
- TMS320F28P55 controller for digital control
- One rack can do APB and EIS at the same time and have no effect on the other
