Electrochemical energy storage battery parameter table

Electrochemical class energy storage dissolved in liquid electrolytes has become the focus of attention in recent years, and has also gained many practical applications. At present, electrochemical energy storage mainly includes a variety of secondary batteries, including lead-acid batteries, lithium-ion batteries, sodium-sulfur batteries and flow batteries, and most of these batteries are relatively mature in technology. Lithium ion battery is actually a lithium ion concentration battery, the positive and negative electrodes are made of two different lithium ion embedded compounds. During charging, Li+ is deembedded from the positive electrode into the negative electrode through the electrolyte. At this time, the negative electrode is in the Li-rich state, while the positive electrode is in the Li-poor state. On the contrary, Li+ deimpinges from the negative electrode and embeds into the positive electrode through the electrolyte. The positive electrode is in the Li-rich state and the negative electrode is in the Li-poor state. Electrochemical energy storage system is mainly composed of battery pack, battery management system (BMS), energy management system (EMS), energy storage inverter (PCS) and other electrical equipment. BMS is one of the core components, which is mainly used for intelligent management and maintenance of each battery unit, real-time monitoring of the operating state of battery SOC, SOH, etc., to prevent the safety risks of the battery body or system, and facilitate the safe and efficient use of energy storage batteries. Energy storage BMS industry is a knowledge - and technology-intensive industry, involving battery management technology, automatic control technology, power electronics technology, communication technology and other technical fields, requiring a large amount of professional knowledge and experience precipitation, with high technical barriers, in which software algorithms and the combination of software and hardware are the core competitive factors. Some customers consult energy storage manufacturers quotation list, today the author to iron phosphate lithium battery as an example, for you to introduce the energy storage manufacturers quotation.
