The standard battery is a chemical battery. Because of its relatively stable electromotive force and good reproducibility, it has been used as a voltage standard internationally for a long time. Used as a standard auxiliary battery when measuring and calibrating the voltage of various batteries. According to the situation of cadmium sulfate solution in the battery, there are two types: saturated and unsaturated. At 20 ° C, the saturated electromotive force should be in the range of 1.0185-1.1868 volts; the unsaturated electromotive force should be in the range of F1.01860-1.01960 volts. The former is characterized by stable electromotive force and a large temperature F coefficient (temperature vs. electromotive force change); the latter has a small temperature coefficient and is easy to use. Generally for industrial and laboratory use. It was invented by American electrical engineer E. Weston in 1892, so it is also called Weston battery.
The battery test according to the IEC 60950 standard is also different for each country.
