What is the battery model for the Mercedes-Benz E200?
1 Answers
Mercedes-Benz E200 uses a 20-80 model battery. Here are the specific details: 1. Introduction: A battery is a type of storage cell, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. 2. Working Principle: The negative electrode is a lead plate filled with sponge-like lead, and the positive electrode is a lead plate filled with lead dioxide, using 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate, while lead dioxide acts as the positive electrode, undergoing reduction to also form lead sulfate. When charging with direct current, lead and lead dioxide are generated at the respective electrodes. After disconnecting the power source, it returns to its pre-discharge state, forming a chemical cell. Lead-acid batteries can be repeatedly charged and discharged, known as secondary cells. Their voltage is 2V, and typically three lead-acid batteries are connected in series to achieve 6V. Automobiles use six lead-acid batteries connected in series to form a 12V battery pack. Regular lead-acid batteries require the addition of distilled water after some use to maintain the electrolyte's 22-28% dilute sulfuric acid concentration.
