STUDY OF THE THERMAL PROCESSES OF THE BATTERY DURING VEHICLE OPERATION IN LOW TEMPERATURES

The article discusses the problem associated with the operation of a vehicle in a cold climate, where we should take special measures to maintain a favorable temperature mode of the battery of the internal combustion engine. Examines factors affecting the condition of the engine and car battery. The analysis of factors influencing starting of the vehicle in conditions of low negative temperatures. The degree of influence of internal resistance of the battery to start the vehicle. The article deals with the problem associated with the operation of the car in conditions of low negative temperatures, the necessity of taking special measures to maintain the optimum temperature regime of the battery is justified. The analysis of the factors influencing the launch of the car in conditions of low negative temperatures is carried out. The factors affecting the state of the vehicle’s battery are considered. The influence of the value of the internal resistance of the battery on the power indicators of the electric starter system and, accordingly, on the probability of starting the engine of the car is shown. To confirm the theoretical assumptions, experimental investigations were carried out, during which the dependences of the internal resistance of the battery on the temperature of the electrolyte and the degree of its charge were obtained. According to the results of the study, it is proposed to use a device that provides pre-start preparation of the battery to increase the probability of starting the engine in conditions of low negative temperatures.
