- Multiple options for working voltages and voltage isolation. Not all transformers are suited for all applications. Pulse offers a range of transformers for BMS, including HM2100NL, HM2101NL, HM2102NL, HM2103NL, HM2106NL, HM2112ZNL, and HM2113ZNL.
- Meets AEC-Q200 requirements for automotive applications. The Automotive Electronics Council has put several industry standards in place to assure the reliability of electronic components used in vehicles. Our products meet AEC-Q200 standards. Our components are designed for durability, as well as their ability to resist thermal shocks and high temperature and humidity.
- Operating temperatures from -40 C to 125 C. The temperature of a circuit can vary considerably. Pulse Electronics’ BMS transformers operate efficiently in a wide range of temperatures, to assure the battery’s reliability and safety in a variety of conditions.

Components for Electric Vehicles
To meet the demand, Pulse introduced a new series of components specifically designed for the most stringent requirements of battery managment (BMS) for electric vehicles and energy storage systems. In large battery pack applications with daisy chain connections, the number of cells connected in series is very high. And, the large voltage differences demand component to component isolation. The serial communication links betwee circuit boards need to be isolated by transformers coupling circuits instead of capacitor coupling.
