Over the next few years, the forecast for demand in electric vehicles (EV) is predicted to dramatically increase. The sales of electric vehicles are expected to surpass the sales of traditional internal combustion vehicles in less than 20 years. In 2017, the UK government announced that they will be banning to sale of any new petrol or diesel cars in 2040.
This means that designers and engineers need battery management systems that are designed for efficient battery capacity and increased battery lifetime. Due to this demand, Pulse Electronics Networking have developed enhanced battery management system components.
How Do Battery Management Systems (BMS) Work?
Large battery packs usually consist of a “daisy chain” structure, meaning that many cells are linked in sequence. The voltage in these cells can differ dramatically between each one. To ensure a safe operation, each component needs to be strictly isolated from each other.
In many modern BMS systems, serial communication links between circuit boards are isolated with transformer coupling circuits, rather than capacitor couplings.
Because of the high number of transformer coupling circuits used in most BMS applications, and the importance of their performance to the life of the battery and the BMS, these components need to be reliable.
Battery Management Systems (BMS) features include:
- Multiple options for working voltages and voltage isolation
- Meets AEC-Q200 requirements for automotive applications
- Operating temperatures from -40 C to 125 C

Automotive manufacturers are expecting an increase in demand for electric vehicles; the quality of the transformers and other components within BMS has a direct impact on the quality of the BMS itself. Components must meet strict industry standards, and be able to operate in a wide range of temperatures. Pulse Electronics have designed several components that meet strict industry standards and are able to operate in a wide range of temperatures, offering engineers multiple options for working voltage and voltage isolation. Not only are these transformers reliable and durable, Pulse Electronics ensures that they are a cost-effective choice to contribute to the improvement of safety, efficiency and longevity of electric vehicles (EVs), plug-in electric vehicles (PHEVs) and hybrid electric vehicles (HEVs).
