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

Embodiment Construction

[0038] Below in conjunction with accompanying drawing, structure principle and working principle of the present invention are described in detail:

[0039] see figure 1 , figure 2 , image 3 and Figure 4, are the structure diagram of the battery monitoring system of the present invention, the circuit block diagram of the battery monitoring device of the present invention, the circuit block diagram of the battery pack of the present invention, and the operation state machine of the controller of the battery pack of the present invention. The battery monitoring system 100 of the present invention includes a battery monitoring device 10 and one or more battery packs 30, such as: battery pack A1, battery pack A2, battery pack A3, ..., battery pack A N . When one of the battery packs 30 is overheated, the overheated battery pack 30 will actively issue a warning signal 315 , and the warning signal 315 will be transmitted to the battery monitoring device 10 by means of short-ra...

Abstract

The present invention provides a temperature monitoring system, comprising a battery monitoring device and at least one battery pack in storage, the battery monitoring device comprising a warning notification unit, and each battery pack respectively comprising at least one battery cell, a controller and a temperature sensor , when the controller of the battery pack uses the temperature sensor to monitor that the temperature of the battery cell is higher than a safe temperature value, a warning signal is generated, and the warning signal is directly transmitted to the battery monitoring device by a short-distance wireless communication method or a short-distance wireless communication method. The communication method is transmitted to the battery monitoring device through multi-point hopping transmission of other battery packs. After the battery monitoring device receives the warning signal, it uses the warning notification unit to present the warning signal. Then, the present invention monitors the temperature of the battery pack in storage in real time. In order to reduce the probability of the battery pack burning or exploding.

Description

technical field [0001] The present invention relates to a temperature monitoring system and method, in particular to a system and method for monitoring the temperature of a battery pack in a box. Background technique [0002] During the production process of the battery pack, the production line is usually provided with a battery monitoring system. The battery monitoring system is used to monitor the temperature of the battery pack to avoid overheating during the production of the battery pack. After the battery packs are produced one after another, the manufacturer takes out the produced battery packs from the production line and stores the produced battery packs in a stacking manner. [0003] In the past, battery packs and their storage boxes are usually not provided with relevant interfaces for communication. When the battery is assembled into the box, the battery pack will be isolated from the outside world. Therefore, if the packed battery pack is overheated during s...
