× 32 db mérőkártya (LMU) kezelésére képes (32×8=256 cella)
× CANOpen hálózaton át kapcsolódik a jármű (pl. elektormos autó) kommunikációs hálózatára
× az akkumulátor töltő(ke)t analóg, illetve PWM jellel vagy CAN-en át vezérli
The system is designed around a distributed architecture with a master board communicating over a galvanically isolated RS485 bus with up to 32 slave boards. Each slave board can connect 3-8 cells in series and 2 temperature sensors. The s-BMS hardware has been designed with special consideration to EMC and temperature performance. All connections to and from the boards are protected by transient voltage suppression circuits (TVS). The operational temperature is from -40oC to 85oC for which the hardware is certified. The system is also available as housed units with IP61 protection.
The PC configuration and diagnostic software is the gateway to the s-BMS providing a wide range of system configuration tools easy to use as well as displays for monitoring battery and BMS performance.
To simplify integration, a powerful, fully user-configurable CAN bus platform is included allowing CAN messages to be constructed at "
A key function of any BMS is safety. The s-BMS provides notification and user-definable system responses for 27 different fault and 17 warning conditions in charge and discharge mode, separately.
