Automotive high-voltage BMS reference design: 18S wired or wireless cell supervisor unit
TIDA-020076
概覽
This reference design implements a cell supervision unit for up to 18 cells. The unit can be daisy-chained to cover typical high-voltage battery ranges used in passenger cars, commercial vehicles, and two- and three-wheelers operating at voltages higher than 72V. The reference design features both wired and wireless interfacing options to enable side-by-side comparison of wired and wireless battery management system (BMS) performance.
特點
- Cell Supervision Unit (CSU) for 6 to 18 cells, stackable for high-voltage BMS. Optional bus-bar support
- High-accuracy cell voltage measurement and integrated cell-balancing
- Wired: Isolated differential daisy chain with optional ring architecture, capacitive and inductive isolation
- Wireless: wireless state of charge (SoC), ISO26262 and IEC61508 certified on system-level Automotive Safety Integrity Level D (ASIL D) capability
- Various additional interfacing options for communication and environmental sensor integration: universal asynchronous receiver transmitter (UART), serial peripheral interface (SPI), general purpose IO (GPIO), I2C
- Optional DCDC for increased system efficiency during key-off and active states
