Battery Isolated IsoSPI CAN Converter Unit
(Battery Communication Unit)
SAYKAL’s IsoSPI-to-CAN Converter is a high-voltage isolation module that facilitates safe communication between battery cells/modules and BMS systems. Using the IsoSPI protocol, it ensures noise immunity and electrical protection in harsh EV environments. This converter is crucial for maintaining reliable communication in 400V–800V battery architectures, especially in multi-cell series designs where isolation is mandatory.
