Conventional energy storage systems face inefficiencies in temperature control, leading to reduced working efficiency of battery packs in low-temperature environments, complex system structures, and high energy waste due to faulty temperature control systems affecting the entire system.
Innovation Solution
The system employs multiple independent temperature control systems, each controlling specific battery racks or groups of racks, allowing targeted temperature management and reducing energy waste by isolating faulty components, with flexible control strategies to ensure continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single centralized temperature control system is used for all battery racks, then the system structure is simpler, but the reliability decreases and energy waste increases when faults occur
Solution Approach 1:
The patent divides the temperature control system into multiple independent regional temperature control systems, each responsible for specific battery racks. This segmentation allows isolated operation and maintenance of individual regions without affecting the entire system, thereby improving reliability while maintaining manageable complexity through modular architecture
2Device complexity
If a single centralized temperature control system is used for all battery racks, then the device complexity is reduced, but the energy waste increases when faults occur
Solution Approach 1:
By segmenting the temperature control into independent regional systems, the patent enables selective operation of only those temperature control systems that are currently needed. When certain battery racks are not in operation or are faulted, their corresponding regional temperature control systems can be shut down, eliminating energy waste associated with heating or cooling unnecessary regions
3Reliability
If multiple independent temperature control systems are used for different battery racks, then the reliability and heat dissipation efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent implements segmentation by creating multiple independent regional temperature control systems, each with its own control unit and temperature control device. This modular approach improves reliability through isolation of faults while managing complexity through standardized module design that can be independently installed, operated, and maintained
4Loss of energy
If multiple independent temperature control systems are used for different battery racks, then the heat dissipation efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by providing customized temperature control for different regional battery racks based on their specific heat generation characteristics and operational requirements. Each regional temperature control system can be optimized for its specific location and battery rack configuration, improving heat dissipation efficiency while maintaining overall system manageability through localized control strategies

AI summary
This application provides an energy storage system and a power supply system. The energy storage system includes N battery racks and at least two temperature control systems. Each battery rack includes a plurality of battery packs. Each battery rack can independently perform charging and discharging. The at least two temperature control systems are configured to control temperatures of the N battery racks. Two different temperature control systems in the at least two temperature control systems are configured to respectively control temperatures of two different battery racks of the plurality of battery racks. Herein, N is an integer greater than or equal to 2. In this embodiment, different temperature control systems are independently disposed. In this way, each independent temperature control system has a simpler structure, and can be conveniently replaced and maintained. A probability that the entire energy storage system cannot work can be reduced. When temperature control needs to be performed for a battery rack, only a corresponding temperature control system of the battery rack needs to be controlled to work. This helps reduce power consumption and reduce energy waste. When a temperature control system is faulty, a smaller quantity of battery racks are affected, thereby reducing losses.
