| description | The invention provides a lithium ion battery thermal characteristic analysis system and method. The system comprises a battery testing device, an infrared thermal imaging detection device, a temperature protection device and an alarm device, and the devices can perform mutual feedback to obtain a surface temperature distribution image of the lithium ion battery in the charging and discharging process, so that the surface temperature data of the lithium ion battery is obtained through analysis. And alarm and protection control are carried out when the surface temperature exceeds the highest use temperature. According to the scheme, continuous surface measurement can be carried out on the overall temperature of the lithium ion battery, the measurement precision is high, more visual temperature change data can be rapidly obtained through analysis so as to control the charging and discharging process, and therefore the thermal runaway risk of the lithium ion battery is reduced, and support is provided for battery |
