Energy storage System Can Recover Subway Energy?

First of all, take a good look at the entire energy storage system. The whole energy storage system is merely an enormous energy storage tank. It is mainly made up of a battery pack, power conversion system, battery management system, and monitoring and control system. The battery pack is the core of any energy storage system, typically consisting of a great many high-performance battery monomers such as lithium-ion batteries and lead-acid batteries. The characteristics of different types of batteries are different, with each type having its own application scenarios. Lithium-ion batteries have high energy density and long cycle life and relatively light weight, making it suitable for applications that are very demanding in terms of space and weight. Lead-acid batteries possess the advantages of low cost, mature technology, and high reliability.

The power conversion system is responsible for the energy conversion between the battery pack and the external grid or other power equipment and plays a key role in the charging and discharging process. The battery management system is the “guardian” of the battery pack, which monitors the status of the battery at any time to ensure that the battery works safely, reliably, and efficiently. For example, it monitors the voltage, temperature, and current of a single battery cell, manages the balance of the battery, diagnoses faults, and protects it. It monitors and controls the whole energy storage system in real time and automatically controls the charge and discharge process according to the pre-set strategies and external requirements. Now, let’s take a look at the energy problem in subway operation.

 Subway, as an indispensable means of transportation in modern cities, undertakes a large number of passengers every day. However, it cannot be separated from strong electric power support in an efficient operation. In the process, there are some problems of energy waste, however. When the subway brakes, a lot of energy will be generated, which usually dissipates in the form of heat, just like the most precious wealth is wasted-it is really regrettable.

But with the addition of energy storage systems, this changed dramatically. An energy storage system is much like an enormous energy treasure house capable of recovering the energy generated during subway braking, properly storing it, and then releasing it right on target to provide power when the subway needs it. Just like in our daily life, items that are temporarily not in use are sorted and put in a suitable place, then taken out and used when needed; this is very convenient and efficient.

Let’s take a look at the example of Guangzhou Metro first. In this southern bustling city, the subway network crisscrosses and provides great convenience for people to travel. Guangzhou Metro has actively introduced advanced energy storage systems in an attempt to improve energy efficiency. When the train is at high speed on the track and needs to brake, huge energy will be transferred to the energy storage system in a very short time. A set of high-performance batteries, like hardworking small guards, is always ready to receive and store this precious energy.

They are characterized by a very high energy density with very long cycle life for large electrical energy storage safely and stably. If acceleration of the train or other occasions necessitates additional power, energy will not hesitate to emit immense power support for the running vehicle. In this way, Guangzhou Metro not only greatly reduces its dependence on the power grid and saves energy consumption but also makes an outstanding contribution to the environmental protection cause of the city. According to statistics, since the establishment of the energy storage system, the energy consumption of Guangzhou subway has significantly decreased, which also indirectly reduces the demand for traditional energy and lays a solid foundation for sustainable development in the city.

Look at Shenzhen metro. Full of innovative vitality, this city has been at the forefront of both subway construction and operation. Shenzhen Metro continues to actively explore the energy storage system application by consistently innovating and optimizing technologies in order for the energy storage system to recover and release the energy more efficiently and stably. During the operational processes of Shenzhen Metro, it is an unknown hero from behind the scenes that allows the subway to work not only safely but also effectively.

The energy storage system of Shenzhen Metro adopts advanced control technology, which can automatically adjust the energy recovery and release strategy according to the running status and energy demand of the train. For example, in sections with frequent train braking, energy storage systems are more aggressive in recovering energy to ensure maximum use of these valuable resources. When acceleration or uphill climbing is required, the energy storage system will respond in real time to provide enough power for the train. This intelligent operation mode improves not only the efficiency of energy use but also reduces the operating cost and injects new vitality into the sustainable development of Shenzhen Metro.

In addition to Guangzhou and Shenzhen, there are many other cities in the country that are also gradually introducing energy storage systems. For example, the subway networks of major cities such as Shanghai subway and Beijing subway are also actively exploring and trying the application of energy storage systems to improve energy efficiency, reduce operating costs, and contribute to the green development of the city.

The benefit of recycling subway energy by the energy storage system is not reflected in energy conservation, it also has a positive impact on the overall development of the city. First, recycling the braking energy of the subway will reduce the dependence on traditional energy and reduce the pressure on the energy supply of the city. It is all the more important in today’s increasingly tight energy situation. The application of energy storage system can reduce carbon dioxide during subway operation, contributing to improving the quality of urban environment. With the improvement of environmental awareness of people, green traveling has become the fashion and trend. As a green and efficient transport system, the subway has further enhanced its green attributes by adopting an energy storage system, setting an example for the sustainable development of the city.

In addition, the application of energy storage system can also improve the stability and reliability of subway operation. This is because the energy storage system can provide emergency backup power for the subway in case of power grid failure or insufficient power supply, ensuring the normal operation of the train. This is of great significance to ensure the life safety and convenience of passengers.

In a word, Energy Storage System applied in Subway Energy Recovery brings a new change to our urban transportations. It not only made subways more energy-efficient and environmentally friendly but also furthered the improvement of efficiency and reliability in subway operations, greatly contributing to the city’s sustainable development. In the future, people believe that when technology has been progressing continuously and increasingly, energy storage systems can be applied to more places to offer us a bright future. Let’s look forward to more significant roles that can be taken by the energy storage system in the field of urban transport so that people’s travels can be green, fast, and time-saving.
