AI Customer ServiceFor the voltmeter protection, use a series resistor to limit current and a shorting diode to prevent reverse voltage. It will let a reverse voltage equal to the forward voltage drop of the diode through. Assuming the series resistance of the voltmeter is very high, the series resistor will not require any correction in the voltage measurement.
Using current sense resistors such as the Bourns® CSS series for battery management provides a very accurate and cost-efective method to meet these needs. They provide low ohmic at less than a milliohm, meeting the low voltage drop and high accuracy requirements. Current sense resistors can handle the high current of a 100-1000 Amp engine starter.
Current sense resistors work by detecting and converting current to voltage. These devices feature very low resistance values, and therefore, cause only an insignificant voltage drop 10 to 130 mV in the application. A shunt resistor is placed in series with the electrical load whereby all the current to be measured will flow through it.
Assuming the series resistance of the voltmeter is very high, the series resistor will not require any correction in the voltage measurement. When the diode is reverse biased (up to the breakdown voltage) it effectively be open.
Different shunt sense resistors can monitor different current ranges, yet be scaled through gain settings to provide the same range of output current in each direction. This is ideal for battery charging application where the charging current has a much smaller range than the battery load current.
Placing this component in series with the current being measured develops a proportional differential voltage as the current passes through the resistor. The remaining blocks in the signal path are selected based on how this measured current information is to be used by the system.
