Problems solved by technology

[0003] However, there are various restrictions in the actual design that make it impossible to use the complete parallel connection of each PACK. Some reasons are due to the limitation of the maximum cooling water flow. For example, the capacitor system and the vehicle share the air conditioner, the water flow is generally small, and the full parallel connection cannot be used. Meet the minimum cooling water requirement of PACK; others due to layout space constraints, such as no space for parallel pipeline arrangement; or if parallel pipelines cannot be evenly and symmetrically arranged to ensure equal water flow of each package PACK, it is necessary to design a considerable amount in the system Flow valve and flow meter, and need to correct the flow regularly or use electric control valve for real-time control

Description

technical field [0001] The invention relates to a capacitor pack or battery pack cooling system and a control method thereof. Background technique [0002] For a system composed of multiple supercapacitor packs or battery packs (hereinafter referred to as PACK) connected in series and parallel, in order to ensure the temperature balance of the individual cells in each PACK, the best cooling solution for the system is to use a parallel water circuit design for each PACK. [0003] However, there are various restrictions in the actual design that make it impossible to use the complete parallel connection of each PACK. Some reasons are due to the limitation of the maximum cooling water flow. For example, the capacitor system and the vehicle share the air conditioner, the water flow is generally small, and the full parallel connection cannot be used. Meet the minimum cooling water requirement of PACK; others due to layout space constraints, such as no space for parallel pipeline ...
