Maximum Isolation for Battery Management Systems
Würth Elektronik expands its WE-BMS transformer series for battery management systems with versions for an operating voltage of 1500 VDC. The component design features enhanced isolation in line with IEC 62368-1 with triple-insulated wire (primary and secondary side), as well as galvanic isolation and a test voltage of 6400 VDC. All this makes the new models in the series ideal for use in large stationary energy storage systems from solar and wind farms, in intermediate storage systems in high-power charging stations to balance out peak loads, or for uninterruptible power supplies used in critical infrastructures. The WE-BMS signal transformers are now also available for an operating voltage of 1500 VDC.

Battery management systems ensure safe operation of battery packs and provide information on battery and charge status. The downstream BMS controllers are connected in series, as are the battery cells. As voltage differences and electromagnetic interference can arise between the components connected in series, a BMS transformer helps isolate the components from each other and suppress interference. The latest members of Würth Elektronik's BMS transformer series guarantee this, even in systems with a high operating voltage of up to 1500 VDC. The longevity of the enhanced isolation of the modules as defined in IEC 62368-1 was tested using the partial discharge test in accordance with IEC 60664-1.
The transformers for battery management systems are now available from stock without a minimum order quantity.
