Technical Field

[0003] The present invention relates to the technical field of battery processing equipment, and in particular to a battery restraint charging and discharging water-cooling constant temperature integrated machine. Background Art

[0004] With the rapid development of new energy vehicles, the demand for batteries is increasing. Batteries release a large amount of heat during charging and discharging, raising the ambient temperature and leading to inaccurate battery capacity measurements. They also produce a large amount of gas, causing battery expansion and affecting battery quality. Existing equipment addresses this expansion by using a restraint machine to restrain the tray. However, adding a complete restraint system significantly increases costs and takes up more space. Traditional fans provide limited cooling performance and are insufficient to meet these requirements.

[0005] After searching, it was found that there is no constant temperature equipment specifically for battery restraint charging and discharging equipment on the market in the existing technology. How to ensure that the temperature inside the battery restraint charging and discharging equipment remains constant during normal operation, ensure that the test results are not affected by the ambient temperature, and improve the quality and efficiency of battery production are problems that need to be urgently solved in this field.
