CTECHi small lifepo4 battery 12v customized for solar energy

3.2V 140Ah Rechargeable Prismatic LiFePO4 Cell the application solution as following: (1) Outdoor integrated iron battery power solution The outdoor communication base station is directly exposed to the sun. The life of the built-in lead-acid battery is usually less than 2 years. This solution uses lithium iron phosphate battery, which has excellent high temperature resistance and a life expectancy of 5-10 years. In this scheme, the battery has the advantages of small volume, light weight, high temperature resistance and long service life, and achieves the purpose of energy saving and emission reduction in three aspects of “energy saving”, “material saving” and “land saving”, and effectively reduces maintenance and operation costs. (2) Non-air-conditioned base station power supply solutions such as Murong The base stations of the village-to-project are located in remote rural areas. They are small in size and small in configuration. Basically, there are no air conditioners, and power outages are frequent. Lead-acid batteries have short life, frequent replacement, and high maintenance costs in remote rural areas. The use of iron batteries, high temperature performance, deep charge and discharge, long cycle life, small size, light weight, light installation, can achieve energy saving and emission reduction in the three aspects of "energy saving", "land saving" and "material saving". It also improves the quality of network power. (3) Space-intensive indoor macro base station power solution The number of indoor macro base stations is large, covering a large area, requiring reliable power supply, so there are generally two sets of battery backup power. The lead-acid battery in the station has a large area and a heavy weight. When the traffic volume increases and the capacity is increased, the space inside the station restricts the possibility of adding new equipment. If an integrated switching power supply is used with the iron battery, the power supply and battery footprint in the equipment room can be reduced to meet the needs of equipment expansion. At the same time, the iron battery has excellent high temperature resistance, and can increase the starting temperature of the air conditioner in the station to about 35 degrees, which can reduce the energy consumption of the air conditioner, effectively reduce the operating cost by saving electricity costs, and achieve the three aspects of “energy saving”, “land saving” and “material saving”. The purpose of energy saving and emission reduction. (4) Indoor coverage / distributed station power solution The indoor coverage of the original 2G network, coupled with the continuous construction of 3G and WLAN hotspots, will further increase the number of indoor coverage stations. Since the indoor coverage site is generally close to selecting the mains, the 48V communication battery module or the iron battery UPS for power supply can effectively solve such problems. (5) High-voltage DC power supply system (HVDC) power supply scheme for communication For the power supply scheme of the data center, industry experts proposed a 240V/336V high-voltage DC power supply system for communication. The system's requirements for batteries are characterized by high voltage (240V/336V), short time, and high current discharge. If you use a rack-type lithium iron phosphate battery pack, you have the following advantages: (a) Light weight and save the cost of equipment room reinforcement; (b) It is small in size and can be placed side by side with the HVDC system in the form of a column head cabinet. It is not necessary to establish a battery room separately, and the floor space of the power supply system can be saved, and the installation rate of the communication equipment rack can be improved; (c) The iron battery can discharge at a high rate and reduce the capacity of the battery configuration; (d) The iron battery discharge platform is stable, and the stable input voltage in the battery power supply mode prevents the device from causing an abnormality due to a wide range of fluctuations in the input voltage. (6) Embedded UPS AC power system power supply scheme For small and medium-sized data centers, developed countries in Europe and America also have an embedded UPS distributed power supply scheme, that is, using a small power UPS and a network cabinet to supply power to the server in units of cabinets. Choosing an iron battery UPS has the following advantages: (a) Light weight and save the cost of equipment room reinforcement; (b) Small size, 3KVA iron battery machine UPS only accounts for 2U space of the network cabinet, increasing the server installation rate; (c) The long life of the battery, the mainframe and battery life are almost the same, reducing the cost of battery replacement; (d) Good safety, iron battery can not ignite or explode, meet the high security requirements of IDC equipment room
