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.
