Abstract

The invention provides an intelligent control method for a cooling system. The intelligent control method comprises the following steps of: acquiring a temperature sampling signal Vtemp; comparing the temperature sampling signal Vtemp with a first threshold voltage V1, controlling the work of a refrigerating device and starting the refrigerating device when the Vtemp is higher than or equal to the first threshold voltage V1; and comparing the temperature sampling signal Vtemp and a second threshold voltage V2, controlling the work of an overtemperature protection device, starting the overtemperature protection device, closing power battery charging equipment and keeping the overtemperature protection device in an on-state when the Vtemp is higher than or equal to the V2. The invention also provides an intelligent control device for the cooling system. The intelligent control device and method provided by the invention realize intelligent control on the system through a simple analog circuit, achieve an intelligent control effect in a complicated electromagnetic environment or on a power equipment supply without the support of a non-intelligent chip, and have the advantages of favorable stability, simple circuit and low cost.

Description

technical field [0001] The invention relates to the field of electric vehicle power batteries, in particular to an intelligent control device and method for a cooling system of power battery charging equipment. Background technique [0002] In recent years, the research and development of electric vehicles has become the trend of research and development in the automotive industry. Among them, as a key component of electric vehicles, power batteries have become the focus of research and development. The power battery works in a wide ambient temperature range from -40°C to 70°C. When the temperature exceeds a certain level, the charge and discharge efficiency is greatly reduced. Therefore, the charging equipment of the power battery includes a cooling device and an overheating protection device. Correspondingly, the charging equipment for the power battery needs a control device and method for a cooling device and an overheating protection device. [0003] Current control ...
