Electrical features of the engine starting system

Keywords: engine, starting system, battery, starter, electrical parameters


The article describes the electrical properties of the engine starting system, that is the acid battery and the electric starter. The dependencies of battery voltage on independent variables affecting them, i.e. capacity, current, temperature or charge status, are discussed. The principles of operation of the battery and electric starter were described and its characteristics were presented, taking into account the properties of the load in the form of a resisting torque and being a source of battery energy. The possibilities of describing the characteristics of the starting system and determining the electrical parameters of the battery and the starter as components of the circuit, i.e. the electromotive force of the battery, resistance, inductance and capacity, are indicated.
