The CSA that uses an external sense resistor has a classic, difference amplifier at its input to sense the small voltage drop across R SENSE . Figure 1 shows a generalized CSA circuit using an ...

Both new solutions focus on protecting the battery and/or on battery parameter retention. This year, Continental will begin to manufacture the all-new high-voltage Current Sensor Module (CSM).

The resistance of the shunt-based current sensor is 25 µΩ, while the Hall-based component is galvanically isolated, with accuracy of 2% at 500 A and 5% at 2,000 A.
