This reference design is a small-sized cell supervisiondemonstrator design for a centralized batterymanagement system (BMS). Its configurablecapacitive isolation daisy-chain solution enablesmonitoring and protecting cells ranging from 6-seriesto 96-series, which allows its use in BMS systemsranging from 24 V to 400 V. In hybrid or electricvehicles (HEV/EVs), a high-voltage lithium-ion batterystores the energy required for traction andhousekeeping. The lithium-ion cells in the battery mustbe monitored while charging and discharging. Thisdesign provides a solution for monitoring lithium-ioncell voltages accurately and communicating the dataexternally via various interfaces such as CAN andbqStudio.
In response to the latest changes in global environmental conditions and efforts to reduce greenhousegases, there is a need to have hybrid or electric traction units, which have very low or zero emissions. In ahybrid electric vehicle (HEV) or electric vehicle (EV), high-voltage batteries are used as storage elementsto power the wheels. Onboard chargers or external DC converters are used to source the power, andhigh-voltage lithium-ion batteries are used to store that energy. DC/DC converters and motor control
