China Mobile 2.5 billion to purchase lithium iron phosphate batteries for communications
On March 4, China Mobile issued a bidding announcement for the centralized procurement of lithium iron phosphate battery products for communications in 2020. The procurement of lithium iron phosphate batteries for communications totaled 610.2 million Ah (3.2V specification), and the procurement requirements will be met for one year.
The bidding announcement stated that the project has set a maximum price limit, and the maximum bid price limit does not include tax and the amount is 250,815.20 million yuan. The bidder’s bid price is higher than the maximum bid limit price Its bid will be rejected.
It is understood that the communication backup power supply is usually installed in the computer room of each base station in the form of a battery cabinet. It provides power when the mains power of the base station is interrupted to ensure the normal operation of the base station. Communication is smooth.
After years of development, the current battery technologies used in the communications field include traditional lead-acid batteries, lithium-ion batteries, fuel cells, flow batteries, etc.
Among them, lead-acid batteries have been used in the communications industry for nearly 25 years, and their drawbacks have become increasingly apparent, especially for the computer room environment and post-maintenance requirements.
Compared with traditional lead-acid batteries, lithium iron phosphate batteries have high energy density, strong safety, high temperature performance, high power output, long cycle life and environmental protection. Etc.
Lithium iron phosphate batteries for communications generally adopt a modular structure. A 48V/50Ah battery pack module is generally composed of 15 or 16 50Ah battery cells in series.
The announcement also shows that the bidding does not divide the bidding section, and adopts the share bidding.
