Экспресс-диагностика электрохимических аккумуляторов энергоустановок подвижных объектов

Abstract

Essentiality of method of express-diagnostics of electrochemical accumulators is considered. The results of experimental studies of nickel-cadmium batteries with different charge level shown. Rapid diagnosis base on the impact on the battery variables in the sign of the current pulses, allows you to define the parameters and characteristics of the battery in a short time, on a range of parameters and without interfering with the battery operation. The main experimental results of nickel-cadmium batteries are presented. These results were included in the mathematical model of determining the state of the electrochemical batteries as a part of power plants. A mathematical model for the diagnosis of an electro-chemical battery is built. The comparison of the calculation results with the experimental results conducted.
