Aging mechanisms and service life of lead–acid batteries
1.. IntroductionThe lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode [1] and Berndt [2], and elsewhere [3], [4].The present paper is an up-date, summarizing the present understanding.
How do batteries work? A simple introduction
What are the main parts of a battery? The basic power unit inside a battery is called a cell, and it consists of three main bits.There are two electrodes (electrical terminals) and a chemical called an electrolyte in between them. For our convenience and safety, these things are usually packed inside a metal or plastic outer case. There are …
The Automotive Ignition System
The distributor is a rotating part that distributes the spark to the correct spark plug at the right time, based on the firing order of the engine. The spark plug wires connect the distributor to the spark plugs, delivering the spark to each plug. And the spark plugs themselves are responsible for actually igniting the fuel in the engine.
