• About 26650 lifepo4 related issues

    Lithium iron phosphate (LiFePO4) has become one of the most widely used cathode materials for lithium-ion batteries due to its high energy density, low cost, stable charging and discharging platform, environmental friendliness, and high safety. However, due to the low ion diffusion rate and poor electrical conductivity of LiFePO4, the rate capability and low temperature performance of LiFePO4 are greatly affected. How to improve its output power, energy density and service life at low temperature is the main challenge for lithium iron phosphate cathode materials. Since Good enough’s research on LiFePO4 cathode materials in 1997, many researchers have carried out in-depth and extensive research on the modification strategies of LiFePO4 materials. So far, the modification methods of LiFePO4 mainly include ion doping, surface coating, morphology control, adding lithium supplementary materials and so on.

  • Home Battery Installation Near Me(Photovoltaic power generation installation)

    Home distributed photovoltaic power generation design and installation steps   1.Design of distributed photovoltaic power generation system   1.Design the power of the panel according to the user’s needs.For specific design standards,please refer to the relevant regulations in GB 50797-2012″Code for Design of Photovoltaic Power Stations”.   Before installing a distributed photovoltaic power generation system,the power of the panels should be designed according to the needs of users.First of all,the daily electricity consumption of the user must be considered.The solar photovoltaic power generation must first meet the household electricity consumption of the user.Only in this way can excess electricity be uploaded to the national grid.   At present,the average monthly electricity consumption of each household of urban residents is about 150 kWh(1 kWh=1 kWh,the same below),that is,the daily electricity consumption is 5 kWh.According to the calculation of the 2000-watt panel system,assuming that the average daily light is 6 hours,the power generation per hour is…

  • Ups Battery Packs in Parallel(Pros and Cons)

      Nowadays,UPS power supply with parallel batteries has become a choice for most users,but what are the advantages and disadvantages in terms of UPS power supply design and UPS battery application?Today,the plb editor will introduce it to you in detail.   When the same charging voltage is the same,when two groups of batteries are connected in parallel,the charging current obtained by each group of batteries is different.In this case,it is possible that the battery pack with small charging current is often in a state of insufficient charging and discharging.After a long time,the internal resistance of this battery pack will increase.Because of long-term power shortage,the greater the internal resistance,the smaller the charging current.,the battery life will be greatly shortened.This situation does not exist when using only one set of batteries.   Therefore,it is recommended that users do not use two sets of batteries in parallel when they can use one set of batteries to…

  • UPS power installation process and precautions

    1) UPS requirements for operating environment The UPS is best installed in a separate room with no conductive impurities and air conditioning, and the operating environment must be clean, dry and protected. The air must be free of dust and corrosive gases. Air circulation must also be maintained when the system is running, and the installation environment must meet a series of conditions: Operating relative humidity: 0~95%, no condensation Operating temperature: within the range of 0~40℃ 2) Unpack and install the cabinet Check for damage Check the packaging to see if there is any damage or wrong installation, if so, you should contact the supplier in time. Unboxing 3) Unscrew the screws at the top and bottom of the side panel of the package, and remove the side panel; 4) Check whether the model on the front door matches the model ordered; 5) Record model data for future use.

  • UPS battery bank connection and UPS battery connection method

    UPS battery connection method The red pole of the UPS battery is the positive pole, and the black pole is the negative pole. The batteries are connected in series in the battery box, that is, the positive pole of one battery is connected to the negative pole of the other battery. According to this connection method, there will be two lead wires, one positive and one negative, which are connected to the battery discharge port. Pay attention to one-to-one correspondence. Generally, the left is positive and the right is negative. When connecting, pay attention to the short circuit of the battery. Water entering the UPS battery in a short period of time will not affect the battery performance. Water is a weak electrolyte and has very weak conductivity. However, it must be wiped dry immediately, otherwise the battery will be oxidized and the battery will fall off, causing damage to…

  • UPS Battery Configuration Guide

    In short, the first thing is to confirm the power of the equipment that people want the UPS to carry, and then the power of the UPS can be confirmed. Generally speaking, the recommended load power is 30%~80% of the UPS power. If the load is too large, the UPS power supply may be overloaded when starting at the same time. If the load is too small, it will not only cause waste, but also be bad for the performance of the battery. How UPS works​​At present, there are three common working methods in the market: backup, online interactive, and online double transformation (line pure online). The details are as follows:​​1 Backup UPS, without voltage regulator, there is a conversion time when the mains and battery are converted, generally used for personal computer protection, or when the performance requirements of the UPS power supply are not high, this type of…
