Problems solved by technology

When the battery continues to work at 45 ° C, its cycle life is reduced by about 60%, which is more obvious when charging and discharging at a high rate
[0004] In the prior art, temperature sensors are often used to detect the temperature of the battery cells in the battery compartment to monitor the temperature of the battery cells. This method can only detect the overall temperature of the battery compartment, but cannot monitor the temperature of the battery cells, which is inconvenient. Fine adjustment, and can not monitor the local overheating caused by abnormal battery cells

Abstract

The invention relates to an infrared field evolution monitoring system of a battery management system. The infrared field evolution monitoring system of the battery management system comprises an infrared monitoring system, wherein the infrared monitoring system comprises a plurality of thermal infrared imagers arranged in a battery bin; according to the invention, the temperature of the battery unit is detected by using the infrared monitoring system, the temperature field of each point of the battery unit can be detected, fine adjustment is achieved, local overhigh temperature caused by abnormity of the battery unit can be effectively detected, the temperature field data is uploaded to a big data cloud server, the big data is integrated for modeling analysis, and the intellectualizationof management is improved.

Description

technical field [0001] The invention belongs to the technical field of battery management, and in particular relates to an infrared field evolution monitoring system of a battery management system. Background technique [0002] Lithium power batteries, the key components of electric vehicles, have defects such as poor material stability, safety problems and unsatisfactory use costs. The most important factor affecting the performance of the power battery is the temperature, so it is necessary to use the battery management system and the thermal management system to manage it reasonably and effectively. [0003] Due to the wide variety of lithium batteries, their optimal operating temperature ranges are also different. For lithium iron phosphate batteries, theoretically, its normal operating temperature range is -10°C to 60°C, but experiments have shown that it cannot drive electric vehicles at low temperatures (below 0°C). Therefore, the temperature control range of lithiu...
