Automotive Electrical EquipmentEnglish version1 Battery《Automotive Electrical Equipment》 Wuhan University of Technology Chen Bifeng IntroductionBasic c

from voltage fluctuations and surges.2. Structure and principle of battery(1) Structure:a. Positive plate: lead dioxide (PbO2)b. Negative plate: lead (Pb)c. Electrolyte: dilute sulfuric acidd. Separator: porous material to prevent short circuit between platese. Container: plastic or rubber material to hold electrolyte and plates(2) Principle:When the battery is charged, lead dioxide on the positive plate combines with sulfuric acid to form lead sulfate and water. At the same time, lead on the negative plate also combines with sulfuric acid to form lead sulfate and water. When the battery is discharged, lead sulfate on both plates reacts with the electrolyte to form lead and lead dioxide, releasing electric energy.3. Types of battery(1) Flooded lead-acid battery: traditional battery with liquid electrolyte(2) Absorbed glass mat (AGM) battery: battery with electrolyte absorbed in glass mats(3) Gel battery: battery with electrolyte in gel form4. Maintenance of battery(1) Keep battery clean and dry(2) Check battery terminals for corrosion and clean if necessary(3) Check electrolyte level and add distilled water if necessary(4) Check battery voltage and charging status regularly(5) Replace battery if it is more than 3-4 years old or if it fails to hold a charge
