Pulse Electronics’ newest BMS transformers, at 3.45mm high, are the markets lowest profile packages and complement the current BMS range of products.
The new options are ideal for use in EV (Electric Vehicle), marine, aviation and ESS (Energy Storage) applications where multiple large battery packs are connected in series and space is at a premium.
BMS transformers protect the digital controller boards from large potential voltage differences which may occur between battery packs. For the BMS to monitor and control each cell/pack, serial communication links between boards are used and these need to be isolated by transformer coupling circuits instead of capacitor coupling due to the high voltages, and in EV applications, a longevity of 15years.
The two newest single channel transformers are qualified with the serial bus communications transceivers from Texas Instruments
Parts areAEC-Q200 certified meeting all automotive reliability requirements and can be manufacture in an ISO/IATF16949 facility.
