Keeping the b attery safe and sound has become one of the biggest concerns of new energy vehicles. There are 4 types of n ew energy vehicles: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV) and vehicles of other new energy sources (high-efficiency energy storage devices, like …
What is a battery? A battery is a self-contained, chemical power pack that can produce a limited amount of electrical energy wherever it''s needed. Unlike normal electricity, which flows to your home through wires that start off in a power plant, a battery slowly converts chemicals packed inside it into electrical energy, typically released over a …
If we are willing to understand the basic principle of battery properly, first, we should have some basic concept of electrolytes and electron affinity. Actually, when two dissimilar metals or metallic compounds are immersed in an electrolyte, there will be a potential difference produced between these metals or metallic compounds.
