Is the charging method of lead-acid battery and UPS lithium battery the same?

Is the charging method of the lead-acid battery the same as the UPS lithium battery? Is the charging method of the lead-acid battery and the UPS lithium battery the same? The charging control method of the lead-acid battery and the UPS lithium battery charger is different, and the difference lies in the data used. The principle of discharge is also different. The charging and discharging of batteries and lithium batteries will directly affect the electrical performance and service life of the batteries. This article is about the difference between batteries and lithium batteries. Is the charging method for lead-acid batteries and UPS lithium batteries the same? There are two types of lead-acid batteries and UPS lithium batteries on the market. These two chargers cannot be used at the same time, otherwise the batteries will be directly scrapped. Because the charging method of the lithium battery charger and the lead-acid battery charger are different. Lithium batteries are charged at constant current and voltage, and lead-acid is charged at three levels. Since lead-acid battery chargers are usually set to a two- or three-stage charging method, the voltage levels of lithium batteries and lead-acid batteries do not match. Lithium battery UPS also has a variety of battery performance, and the parameters of the battery protection board may be different. Therefore, there is no universal charger for lithium batteries like lead-acid batteries. Generally speaking, lithium batteries are transported through special chargers. In order to protect the lithium battery, please use a dedicated charger. The UPS charging control of the lithium battery is first charged according to a safe current, and then when the battery voltage rises to 4.2v, the voltage will not rise, the charger needs to detect the current, assuming that the current is less than a certain value, the charging ends. Lithium charging is active, so the protection circuit is messed up. The maximum charging rated voltage of a single nominal 3.6v battery is 4.2v, and the maximum allowable error is less than 1%. Lead-acid batteries are ambitious charging current pulses. Pulse charging grids are used in the United States for 50 to 60hz power rectifiers without direct filtering. The pulsating DC charging is best (this is based on short circuits and low capital), because of the self-discharge of lead-acid batteries. The rate is very large, choose the labor frequency to charge, the safe voltage charging method is the usual flow) (also must be limited. Lead-acid battery: Lead-acid battery is a chaotic chemical reaction system. The size of the charging and discharging current and its working temperature, etc. External factors will affect the performance of the battery. Calculating the state of charge value of the battery according to parameters such as the car's working conditions and determining the working mode of the car is one of the key technologies for electric vehicles. Lead-acid batteries have the longest history before use, and they are also the most precise. The lowest cost battery has been processed in batches. However, it has lower energy, higher self-discharge rate and lower cycle life. Lead-acid battery charging methods: 1. Pulse charging is simple and economical. This method has a large charging current and a fast charging speed. The disadvantage is that the charging current is not firm when the grid voltage is not maintained. 2. During constant current charging, in order to prevent the internal temperature rise of the lead-acid battery from being too high, the electrolyte loss is too large, and the charging current The adjustment is relatively small, and it takes a long time to charge. On the other hand, if the charging time is too long, overload will occur. In order to prevent overcharging the battery, another overload test or punctual circuit should be set up. 3. Constant voltage charging. Both theory and practice It is proved that when the charging voltage is lower than the upper limit of the charging voltage (for 12V batteries), constant voltage charging is safe. UPS lithium battery: The lithium battery UPS power supply needs to be charged with a supporting charger. In the industrial supporting market, because each product is also It is not common to pack separately. Therefore, the corresponding charger should be selected according to the use of lithium battery packs, and the charging requirements should be strictly followed. No matter in the industrial or commercial market, the basic principle of lithium battery charging is the same, so lithium battery charging Steps and specifications can be specified. In general, the nominal voltage of a lithium battery is 3.7v, and the full voltage is 4.2v. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
