Existing battery charging or discharging processes generate heat, necessitating temperature control of both the apparatus and its installation space, which is inefficient and poses challenges in maintaining optimal conditions for production efficiency and safety.
Innovation Solution
An apparatus and system that incorporates an air treatment unit to cool the charging or discharging module and includes a controller to manage airflow through a module hole based on equipment and zone temperature, current usage, and time parameters to maintain temperature within preset limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the apparatus for charging or discharging operates to charge and discharge battery cells, then productivity is improved, but heat generation increases causing temperature to rise
Solution Approach 1:
The patent utilizes the heat generated during charging/discharging operations to pre-heat air that will be discharged into the installation space. The air treatment unit heats air using the apparatus's own thermal energy, then discharges this warmed air to raise the temperature of the installation space, thereby converting harmful heat into a beneficial heating effect for the surrounding environment.
Solution Approach 2:
The air treatment unit is designed to perform multiple functions: it cools the apparatus during high-temperature operations, heats air using waste thermal energy, and discharges conditioned air into the installation space. This multi-functional approach allows the same component to address both equipment temperature control and space temperature management.
2Temperature
If separate air conditioning equipment is provided for the installation space, then temperature control of the space is improved, but device complexity increases
Solution Approach 1:
The patent merges the air treatment unit with the charging/discharging apparatus, integrating space air conditioning functionality into the equipment's existing thermal management system. The air treatment unit serves both the apparatus cooling function and the installation space temperature control function, eliminating the need for separate air conditioning equipment.
Solution Approach 2:
The air treatment unit is designed as a multi-functional component that simultaneously cools the apparatus and conditions the installation space air. By making this single unit perform multiple roles, the system avoids the complexity of adding separate dedicated air conditioning equipment for space temperature control.
