[0023] The online life calculation method of the battery system proposed by the present invention is composed of the following three parts: 1. Input the total charge and discharge energy of the battery system during the entire life; 2. Calculate the total charge and discharge energy currently completed by the battery system; 3. The online life of the battery system is obtained by dividing the above two energies.
[0024] The total charge and discharge energy of the input battery system during the entire lifespan process can calculate the total charge and discharge energy during the entire lifespan of the battery system by obtaining the two parameters of the rated capacity and the number of cycles marked by the battery at the factory;
[0025] The described calculation of the total charge and discharge energy of the battery system currently completed, first integrate the total current flowing into or out of the battery system during each charge and discharge, and use the integral val...
