The paper presents the results of the mathematical model approbation of the cell of a high-voltage traction car battery. A series of experiments was carried out to obtain the characteristics of the storage battery cell. Experimental studies were carried out in laboratory conditions at the constant temperature of 25 C maintained with a thermostat. The work of the battery cell under load is investigated, for which the characteristics of the output voltage are obtained. Experiments were carried out on charging and discharging a battery cell with a pulsed current - charge with a current of 50A, discharge with a current of 50A, cycle of full discharge and charge. Experimental dependences are obtained which are used to assess the reliability of the mathematical model of a cell created in the MATLAB Similink environment. The input parameter of the model is the load current and the output parameter is the voltage of the battery cell. Comparison of experimental dependencies and the results of mathematical simulation modeling was identified. Moreover, the error of the model was determined, which is <1%, relative to field experiments, which makes it possible to use the model when creating software and hardware complexes for mathematical simulation of vehicle electric system.
