Problems solved by technology

Usually when the vehicle is parked for a long time, the owner needs to unplug the battery negative line, otherwise the battery will be fed and the vehicle will not start
However, it is time-consuming and labor-intensive to manually disassemble the battery negative line.
In addition, frequent disassembly and assembly of the negative pole of the battery will also damage the negative pole of the battery and affect the life of the battery

Embodiment 2

[0035] refer to Figure 4 The second aspect of the present invention, there is provided a method of controlling a power protection system according to a first aspect of the low-voltage lithium battery assembly, comprising the steps of: S100 the mobile terminal sends a power down request to the T-BOX; S200.. the T-BOX power down request signal is converted to power-down;. S300 battery management system in accordance with power-down signal emitted by T-BOX, low pressure lithium batteries powering down.

[0036] Further, in step S300, the battery management system according to the power-down signal emitted by T-BOX, low pressure off the lithium battery group specifically comprises: a battery management system in accordance with the power-down signal T-BOX issued to positive or negative low voltage lithium batteries powering down.

Embodiment 3

[0038]refer to Figure 5 In a third aspect of the invention, an electronic device includes: one or more processors; storage means for storing one or more programs, when the one or more programs are subject to one or more The processor is executed such that the one or more processors implement the method of the second aspect of the present invention.

[0039] The electronic device 500 can include a processing device (e.g., a central processor, a graphics processor, etc.) 501, which may be based on the program stored in the read-only memory (ROM) 502 or from the storage device 508 to the random access memory (RAM) 503. The procedure performs a variety of appropriate actions and processes. In the RAM 503, the various programs and data required for electronic device 500 are also stored. Processing device 501, ROM 502, and RAM 503 are connected to each other through bus 504. The input / output (I / O) interface 505 is also connected to the bus 504.

[0040] Generally, the following devi...

Abstract

The invention relates to a power-off protection system of a low-voltage lithium battery assembly, and a control method thereof. The system comprises a mobile terminal, a T-BOX and the low-voltage lithium battery assembly, and the low-voltage lithium battery assembly comprises a battery management system and a low-voltage lithium battery pack; the mobile terminal is used for sending a power-off request to the T-BOX; the T-BOX is in communication connection with the mobile terminal and the battery management system and is used for receiving a power-off request sent by the mobile terminal and converting the power-off request into a power-off signal; and the battery management system is used for powering off the low-voltage lithium battery pack according to the power-off signal sent by the T-BOX. Through interaction of the mobile terminal, the T-BOX and the battery management system, non-contact power-off protection of the low-voltage lithium battery pack is realized.

Description

Technical field [0001] The present invention belongs to the automotive battery protection and control, particularly to low-voltage lithium battery power protection system and control method. Background technique [0002] With the development of the automotive industry, domestic carbon neutral, so that the EU ban lead to further strengthening the requirements for environmental protection. Compared to lithium batteries, free of heavy metals and rare metals, non-polluting and non-toxic, in line with industry trends, the traditional lead-acid batteries. In the future, the vehicle traditional lead-acid battery will gradually be replaced by low lithium. When the vehicle is usually parked for a long time do not, the owner will need to unplug the battery negative line, otherwise there will be a battery feed, the vehicle can not be started. Artificially negative battery disassembly line, time-consuming. Further frequent access to the battery negative line, the negative electrode pole of t...
