3 terms, definitions and symbols

4 Principle of the method

Under certain conditions, the use of a certain amount of exposure to the indoor simulation of light irradiation of the battery, so that the initial light attenuation. By comparing the photochromic

The maximum output power of the battery under standard test conditions is calculated before subtracting and attenuating the battery, and the initial attenuation rate of the battery is calculated. Standard test strips

The maximum output power of the battery at 1000W/m2, 25 ° C, AM 1.5 is measured according to IEC 60904-1.
