Battery role: 1, battery effect: in parallel with the generator to power electrical equipment. 2, the vehicle battery when the engine start, the power supply to the starter and the ignition system. 3, in the case of the generator not generating power or low voltage power to the electrical equipment. 4, when the generator is overloaded automotive battery manufacturers to assist the power generator 5, the electric storage battery is insufficient, and also when the generator load is less, it may be a generator of electrical energy into chemical energy stored (i.e., charge). 6, the battery is equivalent to a large-capacity capacitor (played a role in stabilizing the vehicle system voltage) the basic working principle of a battery, the battery's basic operating principle ---- chemical reaction PbO2 + Pb + 2H2SO4 2PbSO4 + 2H2O 2, Description: chemical substances involved in the battery reaction: positive electrode plate: PbO2; negative plate: Pb; Electrolyte: aqueous solution of sulfuric acid discharge: positive electrode plate and the negative electrode plate PbO2 Pb PbSO4 electrolytic solution H2SO4 reduced density. Charging: positive electrode plate PbSO4 restored to PbO2; returns to the negative electrode plate PbSO4 Pb. H2SO4 electrolyte solution increases, the density decreases.
