Busbar Shunts - Current Measurement in E-Mobility

Busbar Shunts - Current Measurement in E-Mobility

The automotive industry is currently undergoing a transformation. Electromobility is gaining in importance in all vehicle sectors – from passenger cars to commercial vehicles and passenger transportation. The focus here is primarily on the complete electrification of vehicles and less on the hybrid technology that has been widespread to date. Accordingly, pure
electric motors and their components must become increasingly powerful, precise, reliable and durable.

Both hybrid and electric vehicles are typically high-current applications in which an accurate battery management system (BMS) is of great importance. Three central parameters must be recorded as accurately as possible in the BMS in order to provide accurate information about the range of an e-vehicle: the cell voltage, the cell temperature and the current flow.

Isabellenhütte’s busbar shunts and analog sensors are suitable for measuring high currents. This white paper covers the features, characteristics and possible applications of the different busbar shunt variants. It explains what distinguishes the components of the Isabellenhütte component as well as their specific use cases.
