Battery The battery is the center of the onboard Audi 80 electrical system. Various consumers of food use a stock of its energy, and the battery from the generator is charged. Principle of work The electrode (lead plate) contacts to the divorced sulfuric acid (electrolyte) and gives under the influence of solution positive ions, that is the chastets electrically loaded, to electrolyte. Thereby between electrolyte and a lead plate voltage is created. However it is, not enough, tension created as a result "voluntary" transition of charged particles and on the accumulator give a charge voltage. As a result of it sulfate of lead of the discharged battery turns on a positive electrode into lead dioxide, and on the negative – into spongy lead. At the same time in electrolyte sulfuric acid, an external sign of almost complete process of charging – emergence of vials of gas is again formed. At a discharge of the accumulator there is the return process. Dioxide of lead of a positive plate and spongy lead negative again turn into lead sulfate, and sulfuric acid is spent, and water is formed. Therefore with a discharge of the battery acid density decreases. Designation of the battery In the Audi 80 models with 4-and 5-cylinder engines the battery is located behind on the right in a motor compartment. In models with the 6-cylinder engine: the accumulator is located at the left ahead in a motor compartment. On installation sites it is protected by a cover.
Battery parameters Tension and capacity: 12 B/40 Ach the first (12 V), of course, specifies tension in designation. Behind inclined line the current which the accumulator is capable to give for a unit of time is specified – Ach means ampere-hours. It is the nominal capacity of the battery measured according to standard conditions. In practice it is necessary to count only on 2/3 specified ampere-hours; at older accumulator only on a half. |
