A Battery Management System (BMS) plays a critical role in the adoption of electric vehicles (EVs), as it directly influences key aspects of battery performance, such as range, lifetime, and power output. The BMS is responsible for protecting the battery, prolonging its lifespan, and ensuring optimal performance for its intended application.

One of the most important components of a BMS is the current sensor, which must deliver exceptional accuracy. Cyntec offers a series of current sensors for BMS applications, including Shunt Sensor, Connectorized Shunt Sensors, and Shunt Sensor Modules. A shunt module is an ideal solution for current sensing due to its ease of installation, screw-mounted design, wide measurement range, high precision, and fast refresh rates.

Cyntec also delivers Signal Transformers for daisy chain and the CAN-BUS Common Mode Chokes for CAN-BUS connections, and the Power Chokes for BMS DC-DC power solutions.
