AI Technical Summary

Technical Problem

Existing containerized energy storage systems have complex thermal management systems, resulting in low operating efficiency and high energy consumption, especially in cold and high-altitude environments where efficiency and energy consumption issues are more pronounced.

Method used

The design adopts a direct connection between the air intake device and the centrifugal exhaust fan. Combined with temperature and humidity sensing components and control modules, it can quickly exchange heat by introducing low-temperature airflow from the outside. In extremely cold or hot environments, it can coordinate the temperature control equipment to cool or heat, reduce the air conditioning running time, and use the heat of the battery module itself to maintain the operating temperature.

Benefits of technology

It improves the cooling efficiency of the energy storage system, reduces energy consumption, increases operating efficiency by about 2%, and enables rapid temperature control in extreme environments, thereby reducing the overall energy consumption of the energy storage system.

Abstract

The invention belongs to the field of electrochemical energy storage systems, and particularly discloses a mixed heat management system of a container type energy storage system, which comprises an air inlet device, a centrifugal exhaust fan, a temperature and humidity sensing assembly and a control module, and is characterized in that the air inlet device and the centrifugal exhaust fan are arranged on a container body and are directly communicated to form a heat exchange channel; the temperature and humidity sensing assembly is arranged on the container and used for detecting the environment temperature, the environment humidity and the battery cell temperature. The control module is connected with the air inlet device, the centrifugal exhaust fan and the temperature and humidity sensing assembly, and when the environment temperature is larger than T3 and smaller than or equal to T2 and the environment humidity is smaller than preset humidity, the control module is used for controlling the air inlet device to be started to introduce low-temperature airflow for heat exchange and controlling the centrifugal exhaust fan to be started to exhaust heat exchange airflow. The operation efficiency of the energy storage system can be improved.
