Chongqing Power Leads Industry with AI-Driven Battery System for China’s CR450 High-Speed Train

Industry Leader! Changhong Power Pioneers AI “Pulse” Battery System to Support China’s CR450 Trains

May 13, 2025 – As the wave of artificial intelligence sweeps across various domains, robots are increasingly becoming part of everyday life. From the robot that performs tricks on stage during Spring Festival galas to those transporting goods in factories and even robotic dogs that can shake hands at exhibitions, these technologies are capturing public attention. A key component that enables these robots to function reliably is their battery.

As a company focused on the research and development of new energy system technologies, Sichuan Changhong Power Co., Ltd. (hereinafter referred to as “Changhong Power”) has been actively seizing the high ground in future equipment technology. Its self-developed AI lithium-ion battery packs are now widely used in robots and robotic dogs.

Battery Management

“AI power can provide continuous energy to AI robots, much like a human heart,” explained a representative from Changhong Power. Robots often operate in complex environments that include extreme conditions such as low temperatures, humidity, and vibrations. Lithium-ion batteries, known for their excellent environmental adaptability, maintain stable performance in these challenging conditions, making them the optimal choice for robot power sources.

Changhong Power’s AI lithium-ion battery packs boast high energy density, excellent environmental adaptability, high safety, long lifespan, and relatively lightweight and compact designs. These features ensure the normal operation of robots, while the high safety standards help prevent risks associated with extreme conditions, such as overload, deep discharge, and overheating.

Producing high-performance batteries is one aspect; enhancing their performance to promote efficient energy use and optimal configuration is another challenge. Thanks to breakthroughs in the next generation of AI technology, significant changes are underway in this area. “In broad terms, battery management equates to artificial intelligence; in specific terms, we aim to use technology for extreme control of battery management,” the representative added. Through an AI energy system, the battery packs can achieve unified management, control, and coordination. “Like a human brain, it can detect battery issues in real-time and adjust parameters such as voltage, current, and temperature accordingly.” Changhong Power utilizes cutting-edge technologies like AI to implement collaborative management of batteries, reducing wear and extending their lifespan.

Monitoring and Enhancing Battery Health

In terms of battery safety, the representative stated that during the discharge process, batteries produce heat and encounter uncontrollable factors, requiring constant health monitoring. “Like a doctor, we need to monitor the health status of the batteries continuously. If any abnormalities occur, we must issue timely warnings.” Changhong Power has developed a low-temperature lithium-ion battery pack equipped with an intelligent BMS management device that can take preventive measures like early warnings and “active balancing” to enhance battery safety.

In January of this year, the CR450 train prototypes were unveiled in Beijing, featuring a battery system independently developed by Changhong Power. Compared to traditional nickel-cadmium battery systems of similar capacity, the CR450 lithium battery system is over 57% lighter. This breakthrough in lightweight design is crucial for energy conservation and noise control in rail transport.

Notably, Changhong Power has pioneered the industry’s PHM technology, which, leveraging strong computing power, enables the storage, computation, analysis, and visualization of large amounts of battery system historical data. “We have added a smart health management terminal to the traditional BMS battery management architecture, essentially giving the battery system a more advanced ‘brain,’” said Peng Qiu, the deputy chief designer at Changhong Power. This technology improves battery health management and fault prediction, allowing AI monitoring to assess the battery cell’s “health,” thus extending battery life.

The battery system on the CR450 train not only aids the CR450 in leading globally but also significantly contributes to the localization of equipment manufacturing. It is reported that Changhong Power’s systems equip 60% of China’s high-speed trains, subways, and maglev trains, with extensive use in export locomotive projects in countries like Australia, Argentina, New Zealand, Turkmenistan, and Sudan.

Today, Changhong Power stands as a leading enterprise in China’s aviation power systems, with domestic capabilities in the research and development of power systems and battery products at the forefront of the industry. Its products are widely applied in aerospace, rail transport, industrial support, and energy storage sectors. Looking ahead, Changhong Power aims to further enhance battery management, continuously develop new technologies and materials, and focus on higher voltage and capacity battery systems. The goal is to comprehensively boost core competitiveness and drive the company towards leapfrog development, aspiring to become a globally recognized provider of power system solutions, thereby propelling Chinese manufacturing onto the world stage.
