Hello, I'm looking for a high current sensor which be able to measure 500A (DC measurement) in the ambient temperature range between -40°C to 80°C with high accuracy. I want this sensor to measure a current in an electric vehicle battery.
I made a research and I found that I can use a shunt resistor or Hall effect sensor or fluxgate sensor. I thought to use shunt resistor with an isolation amplifier to ensure galvanic isolation. Is this solution better than other method of measurement? or it's better to use Hall effect sensor or fluxgate sensor since they ensure galvanic isolation ?
