The traditional approach for measuring current is to us a shunt but these fall down when higher (250A+) currents are involved. Because of power dissipation issues shunts need to be low resistance. WebA straightforward way to determine SOC is to keep track of the current flowing in and out of a battery, a method known as coulomb counting. Compared to other methods such as voltage or impedance monitoring, coulomb counting is simple to implement, does not require complex algorithms and is independent of cell chemistry. touw specialist
