CATL Connects World's First and China's Largest BESS Multi-Mixed Energy Power Station (100MWh) to the Grid


GOLMUD, China, Jan. 30, 2019 /PRNewswire=KYODO JBN/ --

Contemporary Amperex Technology Co., Limited (CATL), a China-based manufacturer

of lithium-ion batteries, has delivered world's first and China's largest

battery energy storage system (BESS) multi-mixed energy power station ("the

Station") as part of the Luneng Haixi Multi-mixed Energy Demonstration Project

("the Project"), which is the first of its kind in China to integrate wind

(400MW), photovoltaic (200MW), concentrated solar power (50MW), and an energy

storage system (ESS) (100MWh) into one unified system on the grid.

The Station coordinates three different renewable, with fluctuating and

particularly unstable, sources of energy and is required to respond

consistently to fluctuating demand, making its batteries and battery management

system crucial to the reliability of the system. CATL, the exclusive battery

supplier for the Project, overcome the requirements during product design and

development stage and took merely 17 days to test and commission the BESS to

the grid.

Huang Shilin, Vice Chairman and Chief Strategy Officer of CATL, said, "The

Station is the first of its kind - a multi-functional, centralized power plant

integrated with an electrochemical energy storage system. Its technical

reliability and affordability will promote further global deployment of

different renewable energy applications."

The first priority when building an energy storage station is safety. By

selecting reliable materials, CATL minimize the possibility of failure incident

and second damage explosion. CATL also follows the Potential Failure Mode and

Effects Analysis(FMEA) design process to identify risks and execute risk

mitigation plans in early stages of product development, manufacturing and

management to ensure safe operation of the battery system with well-designed

battery cell, module, cabinet and control system. Utilizing a three-layer relay

protection system, CATL further assures performance of the battery system from

damages caused by over-charging/discharging, over-current, mitigate over and

under temperature working conditions.

One of the key challenges of safety and performances that CATL and the industry

face is thermal management. The Station, installed at Golmud where temperature

varies from -33.6 to 35.5 degrees Celsius. To ensure 15 years of battery

performance, CATL has deployed a cooling system that uses air passages and air

flow designs to maintain a consistent cabinet temperature. A battery management

unit will kick-in the battery cooling system as soon as it detects thermo

concerns, while pre-stored electricity protects the battery from capacity loss

or lithium plating caused by charging in cold temperatures.

In addition, the Project has tough structural requirements, as Golmud lies in

an active seismic zone, which calls for vibration and shock absorption. CATL's

state of the art Test & Validation Center carried out rigorous testing and

simulation to prove its batteries are able to withstand a potential earthquake

of magnitude 8.

According to Dr. Hui Dong, Chief Scientist of China Electric Power Research

Institute, the Station is "the World's first and China's largest

electromechanical energy storage station with virtual synchronous generator."

With the Station as an important part and an expected annual electricity

generation amount of 126,250MWh (401,500 tons of coal generated energy), the

Project is expected to be a good showcase of different new energy applications,

thereby setting standards and smart grid applications around the world.

About CATL

CATL is China's largest battery provider specializing in the manufacturing

lithium-ion batteries for electric vehicles and energy storage systems. It's

devoted to promoting new energy, changing the world via EV & ESS battery

technology. CATL's annual sales volume includes EV & ESS batteries amounted to

12GWh in 2017, EV battery installation volume of 2018 was 23.43GWh.
