The telecom base station requires 24 hours of uninterrupted electrical equipment. The battery pack is an important part of the base station to achieve DC uninterrupted power supply.
At present, mobile base stations use valve-regulated sealed lead-acid batteries (VRLA batteries for short) developed at the end of the 20th century. In the early stage of promotion of this kind of battery, the supplier called it a “maintenance-free” battery. Some maintenance personnel think that this kind of battery does not require maintenance.
This misunderstanding still has an impact today. Judging from the current use of major operators such as China Mobile, China Unicom, and Netcom, it is common for the battery capacity to drop too quickly and the service life to be short. Originally, many maintenance-free lead-acid batteries with excellent design and materials have a theoretical life of 15-20 years or more for floating charge, but there are probably very few batteries that can achieve such a life in use.
Therefore, scientifically strengthening the maintenance and maintenance of this battery pack is still very important to improve its availability.
In order to extend the service life of the battery, the previous method is to cool the entire base station space. In order to meet the constant temperature environment in the base station, 3 or 5 HP air conditioners are usually installed. Cooling in summer and heating in winter.
In this way, the annual energy consumption for base station air conditioners is considerable. According to statistics, there are more than 300,000 base stations in the country, and the annual electricity consumption of air-conditioning in each base station is about 10,000 yuan, a total of close to 3 billion, which has become one of the important expenditures of the communications industry.
Therefore, energy conservation, emission reduction, and cost reduction have received more and more attention from the communications industry. In order to reduce energy consumption as much as possible without affecting the service life of the battery, a variety of methods have been adopted both inside and outside the industry, and there is still no one-size-fits-all solution.
Hop Technology achieves a constant temperature effect by placing the battery in a separate cabinet and using an integrated cabinet air conditioner to cool the cabinet.
The advantages of cabinet air conditioner is that it can reduce a lot of electricity consumption and achieve the effect of energy saving. Reduce energy consumption costs by more than 60%.
Due to the small size of the battery box, the power consumption is a few tenths of the previous one. Two environments of battery working area and non-battery working area are realized. The energy consumption of the entire base station is greatly reduced, thus achieving the original intention of saving energy without affecting the service life of the battery. According to test data, a 600W air conditioner is usually installed in a single-door cabinet, and a 1000W air conditioner is usually installed in a two-door cabinet. Therefore, compared with traditional temperature control methods, the installation of battery compartment air conditioners can save energy consumption by at least 60%
