Embodiment 1

[0020] This embodiment discloses a fast charging battery pack, which includes a single battery 1 , a casing 2 for accommodating the single battery 1 and a cooling fan 3 . The casing 2 is provided with a housing chamber 21, and the bottom of the housing chamber 21 is provided with a PCB board 22. The single cells 1 are arrayed on the PCB board 22, and a number of cooling holes 23 are provided between the single cells. On the PCB board 22 and through the housing 2 , a resistor 7 is provided at the middle of the bottom of the housing cavity 21 .

[0021] The cooling fan 3 is an axial flow fan, which is a prior art, and will not be further described here. There are two cooling fans 3 , both of which are arranged on the top of the accommodating cavity 21 . A positive pole 4 , a negative pole 5 and a charge-discharge switch 6 are also provided on the side of the housing 2 , and the positive pole 4 and the negative pole 5 are arranged on the same side of the housing 2 .

Embodiment 2

[0027] This embodiment discloses a fast charging battery pack. In this embodiment, the cooling fan 3 is an axial fan, including a motor and a fan blade 31, and the motor is arranged in the rotating shaft of the fan blade 31; the side of the fan blade 31 close to the accommodation cavity 21 is a plane, and a PCB board is arranged on the plane. Like several single batteries, the fan blade 31 is a smooth curved surface on the side away from the accommodating cavity 21 .

[0028] Other structures of this embodiment are the same as those in Embodiment 1.

[0029] In this embodiment, a unit battery 1 is provided on the side of the heat dissipation fan 3 close to the accommodating chamber 21 to make full use of the space in the battery pack and increase the capacity of the battery pack. This embodiment can also improve the heat dissipation efficiency of the single battery 1 .

Abstract

The invention discloses a quick charging battery pack. The quick charging battery pack comprises a plurality of single batteries, a housing for accommodating the single batteries and a cooling fan. Byadopting the battery pack mode, single batteries in the battery pack can be directly charged by external voltage during charging, so that the charging efficiency is high, and the charging speed is high. Meanwhile, the cooling fan is arranged in the battery pack, and the battery pack can be cooled in time, so that the cooling efficiency is high, and the cooling fan can be widely applied to the field of rechargeable batteries.

Description

technical field [0001] The invention relates to the field of rechargeable batteries, in particular to a fast charging battery pack. Background technique [0002] With the continuous development of science and technology and people's increasing concern for the environment, traditional fuel vehicles have been difficult to meet people's needs for a healthy life, and new energy vehicles represented by electric vehicles are becoming more and more popular. [0003] An important issue hindering the development of electric vehicles is the battery technology of electric vehicles. Ordinary rechargeable batteries have short battery life and long charging time. People need to spend several hours to fully charge the battery, which seriously affects people's travel experience and the widespread popularization of electric vehicles. [0004] Therefore, the market is badly in need of a rechargeable battery that can be charged quickly. Contents of the invention [0005] The purpose of the...
