What is a BMS Transformer?
A transformer is a device that transfers electric power from one circuit to one or more other circuits, and it can increase or reduce the voltage during the transformation. A BMS (Battery Management System) Transformer is a specialized transformer used in battery management systems to provide isolation, voltage conversion, and signal transmission between different sections of a battery pack and its control electronics, widely used in electric vehicles (EVs), energy storage systems (ESS), and industrial power solutions.
BMS Transformer Advantages
• Functional insulation
High safety distance suitable for 1500V operating voltage, available in functional insulation, basic insulation, and enhanced insulation. Circuit topology: TR+CMC, CMC+TR, etc.
• RoHS Compliant & AEC-Q200 Qualified
Our BMS transformers ensure that they are environmentally friendly and have reliability and performance in demanding environments.
• SMT Package contains transmit transformers
These BMS transformers are optimized for efficient signal transmission, reducing signal loss and improving
• Quality guaranteed
Mentech's battery management system transformers are of excellent quality, with a laser peeling process. Made by FIW+NY wires, they have AEC-Q200 test certification.
• Customized Turns Ratio
Mentech offers custom transformers for BMS to match specific voltage conversion and isolation requirements.
• Wide temperature range
Our BMS transformers operate reliably in harsh environments, from -40°C to 125°C.
BMS Transformer Applications
• Automotive
Battery management system transformers are widely used in battery management units (BMUs) to monitor cell voltage, balance charge, and ensure safety for electric vehicles (EVs) & hybrid EVs (HEVs).
• Energy storage systems (ESS)
BMS transformers can be used in renewable energy storage, such as solar energy and wind energy, to achieve safe and efficient power conversion in solar and grid energy storage.
Introduction: Mentech BMS Transformer
As a transformer manufacturer in China, Mentech specializes in the development and production of BMS transformers, and single-channel, dual-channel, and multiple-channel products are available. Also, we offer different insulation-grade products, including functional insulation, essential insulation, and reinforced insulation.
Mentech uses FIW wires as the material of battery management system transformers, which have better softening breakdown temperature and tensile strength than conventional QPN wire.
With more coatings, these FIW wires can achieve not only zero porosity but also better wear resistance by adding nylon.
To meet clients' requirements, Mentech offers a flat design, and the transformers keep low loss and good filtering effects. We provide customizable services to provide clients with solutions. Feel free to contact us for more details.
