Problems solved by technology

Therefore, if the packed battery pack is overheated during storage or transportation, unless the battery pack explodes or catches fire, warehouse managers or delivery personnel will not be able to detect the overheating of the battery pack
Therefore, once the battery pack in the box is thermally out of control, it will cause a serious fire

Abstract

The invention provides a temperature monitoring system, comprising a battery monitoring device and at least one stored battery pack, wherein the battery monitoring device comprises a warning notification unit, and each battery pack comprises at least one battery cell, a controller and a temperature sensor. When the controller of the battery pack monitors that the temperature of the battery cell is higher than a safe temperature value by utilizing the temperature sensor, a warning signal is generated; the warning signal is directly transmitted to the battery monitoring device in a short-distance wireless communication mode or is transmitted to the battery monitoring device in a short-distance wireless communication mode through multi-point jump transmission of other battery packs; and after the battery monitoring device receives the warning signal, the warning signal is presented by the warning notification unit. Thus, the temperature of the stored battery pack is monitored in real time, and the probability of spread combustion or explosion of the battery pack is reduced.

Description

technical field [0001] The invention relates to a temperature monitoring system and method, in particular to a system and method for temperature monitoring of battery packs in packing and storage. Background technique [0002] During the production process of battery packs, the production line is usually equipped with a battery monitoring system. Use the battery monitoring system to monitor the temperature of the battery pack to avoid overheating during the production of the battery pack. After each battery pack is manufactured successively, the producer takes out the manufactured battery packs from the production line and stores the manufactured battery assembly boxes in a stacked manner. [0003] In the past, battery packs and their storage boxes were usually not provided with communication-related interfaces. When the battery is assembled into the box, the battery pack will be completely isolated from the outside world. Therefore, if the packed battery pack is overheat...
