How to prevent the self-discharge of electric vehicle batteries?

How to prevent the self-discharge of electric vehicle batteries As more and more electric vehicles are used, some problems with the characteristics of electric vehicles have also been highlighted. Quite a few users show that the battery is clear and sufficient, but it has not been used for a week, and when it is used, it becomes more than 90%. What is going on? According to the self-discharge situation, professional electric vehicle battery processing technicians said that self-discharge is the general condition of electric vehicle batteries. This is not the defect of the product itself. Every battery will self-discharge every day. 1% or 2% power. Reasons for self-discharge 1. Reasons for self-planning Whether it is a lead-acid battery or a lithium battery, there will be more or less self-discharge. This is one of the characteristics of the product. Some positive ions and ions will appear during the storage of the electrolyte. Negative ions, users do not have to worry too much about this. 2. Reasons for electrolyte impurities Every electric vehicle battery manufacturer uses lead-acid electrolyte, but the concentration and purity of the electrolyte vary greatly. Normal large manufacturers, such as Xu sent batteries, use battery electrolyte with very high purity, which basically contains no other impurities. The self-discharge rate of their processed batteries is very slow, even lower than the industry average level of self-discharge of batteries, and some small The electric vehicle battery processed by the factory or informal manufacturer has a lot of impurities in the temporary electrolyte, and the self-discharge speed is very fast. Within a few days, it is taken out as soon as it is fully charged. 3. There are problems with the battery itself or external factors. Those who know the battery of electric vehicles understand that when the conductor of the battery is temporary and some forms of the outside of the body build a bridge, it is easy to have a stronger discharge phenomenon, or accidentally put the iron wire, copper The positive and negative pole connections caused by wires, etc. to the battery may also cause discharge conditions. How to prevent battery self-discharge? 1. Good maintenance Users should pay attention to the daily maintenance of the battery, check its cleanliness and integrity, and find that less than half of the batteries should be charged in time. 2. Customers who buy products with good reputation should buy battery products with good reputation and good quality in the market, such as Solectron battery, which has many agents and retail outlets. Various types and capacities of batteries are available for customers to choose from. More importantly, its super battery life and application life save customers a lot of money. 3. Handle with care and lay flat in daily use. When equipment or transfer batteries, handle with care to prevent battery wires from contacting the outside, and also prevent external metals from being connected to the positive and negative poles.
