With the acceleration of the 5G era, supporting 5G base stations are also being launched on a large scale as "new infrastructure." As several major telecom operators in the country accelerate the construction of 5G base station energy storage, the demand for lithium iron phosphate batteries that meet the needs of 5G base stations has surged.

Tower and Telecom release lithium iron phosphate test announcement

Recently, China Tower and China Telecom issued an announcement stating that China Tower and China Telecom will jointly organize the procurement of lithium iron phosphate batteries for backup power. In order to improve procurement efficiency and ensure product procurement quality, the two parties will jointly launch lithium iron phosphate batteries for backup power. The first batch of normalized test work for battery products.

The inspection supplier is required to be a manufacturer of lithium iron phosphate battery pack products, and has independent production capacity of lithium iron phosphate batteries. The sample model is lithium iron phosphate battery pack (integrated) with 48V/100Ah backup power. The "Implementation Rules for the Testing of Lithium Iron Phosphate Batteries" require samples of 5 battery packs, 1 BMS and 9 single cells. The testing of lithium iron phosphate batteries for backup power is divided into three parts: system, BMS and platform access. In terms of performance, the battery should not fire or explode under the conditions of resistance to overcharge, deep discharge, impact resistance, high temperature resistance, and short circuit resistance.

It is reported that under the general trend of 5G base station construction, the purchase of lithium iron phosphate batteries for backup power has become a large expenditure for China's towers. As early as March 11 this year, China Tower issued the "2020 Procurement Announcement on Intensive E-commerce Procurement of Lithium Iron Phosphate Battery Pack Products for Backup Power", and will bid for the procurement of 2GWh lithium iron phosphate battery pack products. Eventually, Shuangdeng Group and Nandu Five companies including Power, Penghui Energy, Zhongtian Technology and Shengyang Power won the bid.

Before China Tower, on March 4, China Mobile issued an announcement to purchase about 1.95GWh of lithium iron phosphate battery products for communications at a maximum price of over 2.5 billion yuan. In the end, eight companies won the bid, namely: Zhongtian Technology and Haisi Da, Shuangdeng Group, Yiwei Lithium Energy, Narada Power, Vision Power, Coslight Power, Lilang Battery, the lowest bidding price is about 0.661 yuan/Wh, and the winning bid is 1.368 billion yuan.
