Description
Technical Field
The utility model relates to a lithium battery technology field, in particular to lithium battery pack that can charge and discharge under low temperature-40 environment.
Background
Lithium batteries are a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a negative electrode material. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of science and technology, lithium batteries have become the mainstream nowadays. Lithium batteries can be broadly classified into two types: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain lithium in the metallic state and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and the safety, specific capacity, self-discharge rate and cost performance of rechargeable batteries were all superior to those of lithium ion batteries. Due to its own high technical requirement limits, only a few national companies are producing such lithium metal batteries today.
The conventional lithium battery pack cannot be charged in an environment with the temperature of-40 ℃.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide a lithium cell group that can charge and discharge under low temperature-40 environment can effectively solve the problem among the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a can charge and discharge lithium cell group under low temperature-40 environment, includes lithium cell group, heating module, circuit board and temperature probe, lithium cell group with circuit board electric connection, heating module with circuit board electric connection, temperature probe with circuit board electric connection, heating module locates the lithium cell group outside, temperature probe locates inside the lithium cell group.
Preferably, the lithium battery pack has a waterproof rating of IP 67.
Preferably, the shell of the lithium battery pack is made of PC plastic resistant to low temperature of-60 ℃.
Preferably, the lithium battery pack is provided with a pressure relief module.
Compared with the prior art, the utility model discloses following beneficial effect has: this kind of lithium cell group that can charge and discharge under low temperature-40 environment through setting up heating module, circuit board and temperature probe, can realize that when the temperature is lower, heating module gives lithium cell group heating, is convenient for charge of lithium cell group.
Drawings
Fig. 1 is a schematic diagram of the overall structure of a lithium battery pack capable of being charged and discharged in a low temperature-40 ° environment according to the present invention.
In the figure: 1. a lithium battery pack; 2. a heating module; 3. a circuit board; 4. a temperature probe.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, a lithium battery pack capable of being charged and discharged at a low temperature of-40 ° comprises a lithium battery pack 1, a heating module 2, a circuit board 3 and a temperature probe 4, wherein the lithium battery pack 1 is electrically connected with the circuit board 3, the heating module 2 is electrically connected with the circuit board 3, the temperature probe 4 is electrically connected with the circuit board 3, the heating module 2 is arranged outside the lithium battery pack 1, and the temperature probe 4 is arranged inside the lithium battery pack 1.
The waterproof grade of the lithium battery pack 1 is IP 67; the shell of the lithium battery pack 1 is made of PC plastic resistant to low temperature of-60 ℃; be equipped with the relief valve on the lithium cell group 1, when lithium cell internal pressure was too big, the relief valve was opened automatically, derived the external world with lithium cell internal pressure, made lithium cell group can last, safe work.
It should be noted that the utility model relates to a can charge and discharge lithium cell group under low temperature-40 environment, when lithium cell group 1 charges, temperature probe 4 gives 3 signals of circuit board, when temperature probe 4 detects lithium cell group 1 temperature and is less than 0 degree centigrade, external circuit gives heating module 2 power supplies, heating module 2 gives lithium cell group 1 heating, when 1 inside temperature of lithium cell group rises to more than 0 degree centigrade, circuit board 3 gives external power supply system signal, begin to charge for lithium cell group 1.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
