Within electric vehicles, the lifespan of a battery hinges on the effectiveness of the battery management system (BMS).  Monitoring parameters such as charge/discharge voltage, current, and temperature in each individual cell is crucial.  Effective testing of BMS performance before installation is critical, and the P41000 high voltage transducer from Knick Interface is a vital tool in the testing process.

P41000 series high voltage transducers: Knick Interface

Precision and Safety with Voltage Signal Conversions

The P41000 is designed to convert voltages from +/- 50 mV up to +/- 100V to standard unipolar/bipolar output signals, (i.e., +/- 10 V and 4...20 mA,) with exceptional accuracy, possessing a gain error <0.1% of measured value.  Its robust design ensures protection against high voltages, seen with its working voltage (continuous isolation) specification of 3600 VDC.

Flexibility for Changing Test Scenarios

With calibrated switching of up to 16 input/output ranges, P41000 allows for seamless adaptation to changing testing scenarios.  This means that it can act as a single solution for multiple conditioning and isolation applications within BMS testing environments.  Use cases have included voltage testing and temperature simulation (mV signals seen with RTDs) in Power Hardware in the Loop (P-HIL) configurations.

 Reliability in High Voltage Environments

Through its continuous isolation capabilitiy to 3600 VDC, P41000 can confidently handle applications seen today, while remaining ready for future demands, as technological advances in the electric vehicle industry continue to push voltages higher.  With its precision, safety features, flexibility, and reliability in high voltage environments, it is the ideal solution for ensuring efficiency of BMS through testing.
