The Battery Management System (BMS) plays a critical role in the widespread adoption of electric vehicles (EVs), as it directly impacts key aspects of battery performance, such as driving range, service life, and power output. The BMS is responsible for protecting the battery, extending its lifespan, and ensuring optimal performance in its intended applications.

One of the most important components in a BMS is the current sensor, which must offer extremely high accuracy. Cyntec provides a range of current sensors for BMS applications, including shunt sensors, shunt sensors with connectors, and shunt sensor modules. The shunt module is an ideal solution for current sensing due to its easy installation, screw-fixing design, wide measurement range, high accuracy, and fast refresh rate.

Cyntec also offers signal transformers for daisy-chain connections, CAN-BUS common mode chokes for CAN-BUS connectivity, and power chokes for BMS DC-DC power solutions.
