Shunt Resistors for Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems require accurate and stable DC current measurement for safety, performance monitoring and long-term reliability. Shunt Europe manufactures high-precision current shunt resistors for industrial and utility-scale energy storage.

Where shunt resistors are used in BESS

  • BMS current sensing for charge/discharge monitoring
  • Protection and diagnostics: overcurrent detection and fault analysis
  • Efficiency monitoring in DC distribution and power conversion
  • Validation on test benches and commissioning systems

Key requirements

Selecting the correct shunt depends on electrical, thermal and mechanical constraints. Typical selection parameters include:

  • Current range (A) and overload profile
  • Voltage drop (mV): commonly 50mV / 60mV / 75mV / 100mV
  • Accuracy / tolerance and temperature drift requirements
  • Operating temperature range and duty cycle
  • Mounting and integration: panel / busbar / compact OEM design
