Key Document
Description
This reference design is a small-sized cell supervision demonstrator design for a centralized battery management system (BMS). Its configurable capacitive isolation daisy chain solution enables monitoring and protecting cells ranging from 6-series to 96-series, which allows its use in BMS systems ranging from 24 V to 400 V . In hybrid or electric vehicles (HEV/EVs), a high voltage lithium ion battery stores the energy required for traction and housekeeping. The lithium ion cells in the battery must be monitored while charging and discharging. This design provides a solution for monitoring lithium ion cell voltages accurately and communicating the data externally via various interfaces such as CAN and bqStudio.
Features
- Scalable cell supervision circuits from 6s to 96s
- Accurate leakage current estimation
- Estimated isolation resistance
- Accurate high-voltage measurement
- Scalable to multiple batteries
