What Should Be the Charging Voltage and Current for a Car Battery?
1 Answers
Car battery optimal charging voltage is 16V. Here is the relevant introduction about car batteries:1. Concept: Car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Generally, the term "battery" refers to a lead-acid battery, which is mainly composed of lead and its oxides, with sulfuric acid solution as the electrolyte.2. Working Principle: The negative electrode is made of a lead plate filled with sponge lead, and the positive electrode is made of 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 the battery discharges, metallic lead acts as the negative electrode, undergoing oxidation and being oxidized to lead sulfate; lead dioxide acts as the positive electrode, undergoing reduction and being reduced to lead sulfate.
