Wurth Electronics has introduced the WE-BMS series signal transformer for battery management systems, which achieves an insulation strength of 4300 VDC/1 min and an operating voltage of up to 1000 VDC, suitable for energy storage systems, electric bicycles and electric scooters.the operating temperature range of the product has been widened to -40 ° C to 125 ° C, with sizes ranging from 7.6 x 9.5 x 5.5 mm to 15.1 x 15.4 x 3.45 mm
In addition to transformers, the new WE-BMS line of products has a built-in common-mode inductor to filter out common-mode noise. Wurth Electronics has a longer creepage range than its market counterparts, but the package is compact, offering a thin model with a height of 3.45mm.
As indicated in the product code WE-BMS, this series of signal transformers is specifically optimized for battery management systems (BMS). Battery management ensures reliable system operation and provides charging status information. Each cell in the battery pack is connected in series, as are the corresponding BMS controllers. Voltage difference and electromagnetic interference will be generated between the series components or circuit boards.
WE-BMS transformers are used to connect the components electrically isolated and suppress EMI. Target markets include energy storage devices such as solar installations, and uninterruptible power supplies (UPS). The WE-BMS series meets the AEC-Q200 standard and is therefore also suitable for electric vehicles. WE-BMS supports serial Daisy chain, isoSPI, and SPI communications.
