Problems solved by technology

[0003] Large-scale lithium battery packs will generate more heat when they are overloaded, and there is a risk of fire or even explosion when they are overloaded for a long time
At present, the maintenance of large lithium battery packs is generally carried out through manual regular inspections, and the impact of the surrounding environment of the battery pack is rarely considered.
There are inherent defects in this method: 1. The time interval of manual detection is long and the detection accuracy is low, so it is difficult to find the faults and hidden dangers of the battery pack and its circuit, especially when testing a large number of lithium battery packs; 2. The working status parameters of the lithium battery pack cannot be fed back in real time, and the fault cannot be warned or dealt with in time; 3. The influence of the surrounding environment of the battery pack is ignored, and the potential safety hazards caused by light and temperature to the battery pack are not foreseen

Embodiment Construction

[0028] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0029] Such as figure 1 As shown, a lithium battery pack protection device, the large lithium battery pack 10 is provided with positive and negative output terminals, the protection device includes a processor 1, a sensing module 2 and an output connected in series to the positive output terminal of the battery pack 10 Switch 3 , the processor 1 controls the on-off of the output switch 3 according to the working state signal of the lithium battery pack 10 fed back by the sensing module 2 .

[0030] The above scheme can monitor the lithium battery pack in real time, and realize timely early warning and processing of faults, so as to ensure the safety of the battery pack and the storage space of the battery pack; compared with the manual detection method, its detection accuracy is higher, and the monitoring is more comprehensive. Feedback is more timely.

Abstract

The invention provides a lithium battery pack protector. A positive output end and a negative output end are arranged on the lithium battery pack. The protector is characterized by comprising a processor, a sensing module and an output switch which is in series connection with the positive output end of the battery pack, and the processor controls on or off of the output switch according to a lithium battery pack working state signal which is back fed by the sensing module. By means of the lithium battery pack protector, the lithium battery pack is monitored in real time, a fault can be timely and early warned and processed, the safety of the battery pack and battery pack storing space can be guaranteed, and compared with manual detecting methods, the lithium battery pack protector is higher in detecting accuracy, further comprehensive in monitoring and more timely in feedback.
