Sodium-sulfur cell batch detecting system

Abstract

The invention discloses a sodium-sulfur cell batch detecting system. The sodium-sulfur cell batch detecting system comprises a plurality of batch detecting furnaces, an intelligent control system, temperature controllers, collection controllers, and a charging-discharging device, wherein sodium-sulfur cells to be tested are arranged inside the batch detecting furnaces, the temperature controller and the collection controller are all arranged on each batch detecting furnace and are respectively connected with the intelligent control system, the charging-discharging device is respectively connected with the sodium-sulfur cells to be tested inside each batch detecting furnace and is connected with the intelligent control system. The sodium-sulfur cell batch detecting system enables the collection controllers to be separated from the batch detecting furnaces and the charging-discharging device so that the charging-discharging device does not need to be accompanied around the batch detecting furnaces in the process of temperature rise and temperature fall, and accordingly detection of voltage and temperature of a single cell in the period can be achieved. Data such as the voltage and the temperature of the single cell collected by the collection controller, guide the operation strategy of the charging-discharging device.

Description

technical field [0001] The invention relates to a sodium-sulfur battery detection system, in particular to a sodium-sulfur battery batch detection system. Background technique [0002] The sodium-sulfur battery is a high-temperature solid-state electrolyte battery with an operating temperature of 300-350°C. The molten elemental sulfur and metallic sodium are used as the positive and negative electrodes of the battery, respectively, and the ceramic tube is used as the diaphragm. The use of sodium-sulfur batteries is based on battery modules. Multiple sodium-sulfur battery cells are placed in a dedicated incubator to form a battery module through a special series-parallel connection. In order to obtain stable electrical performance, the battery module requires sodium-sulfur batteries. Monomers have higher consistency. The production of sodium-sulfur battery cells goes through many processes, such as powder making, molding, sintering, electrode active material injection, glass...

AI Technical Summary

Problems solved by technology

[0004] The current sodium-sulfur battery batch test system does not have a separate acquisition controller, so the charging and discharging equipment needs to be accompanied by the batch testing furnace during the batch testing process; in addition, the charging and discharging equipment does not have a temperature detection and control function, which cannot be realized when the temperature is abnormal.
