How many kilowatt-hours are needed to fully charge four batteries?
1 Answers
It takes about 1 kilowatt-hour to fully charge four batteries. Here is some relevant information about car batteries: 1. Concept: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The battery referred to here is a lead-acid battery, which is mainly made 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 spongy lead, and the positive electrode is made of a lead plate filled with lead dioxide, with 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 is discharging, the metal lead is the negative electrode, undergoing an oxidation reaction and being oxidized to lead sulfate; lead dioxide is the positive electrode, undergoing a reduction reaction and being reduced to lead sulfate.
