Embodiment 1

[0034] Such as figure 1 As shown, the present embodiment discloses a battery pack 1, the battery pack 1 is provided with a heat dissipation air duct, and the heat dissipation air duct passes through as many heat-generating electronic components as possible without affecting the normal use of the interior. Such as power field effect tube and so on. The battery pack 1 is provided with an air inlet 11 and an air outlet 12 , and the two ends of the cooling air duct are respectively connected to the air inlet 11 and the air outlet 12 . The battery pack 1 is provided with a window hiding device at the air inlet 11 and the air outlet 12. When the window hiding device is closed, the corresponding air inlet 11 and the air outlet 12 are closed. When the window hiding device is opened, the corresponding air inlet 11 And air outlet 12 is opened. Such as figure 2 As shown, this embodiment also discloses a charger 3 matched with the aforementioned battery pack 1, the charger 3 is provid...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that this embodiment discloses a charging and heat dissipation control method for a battery pack that is controlled by a battery pack to automatically open and close a window hiding device, such as Figure 5 As shown, the control method includes the following steps:

[0052] Step S1000, detecting that the charger has been plugged in.

[0053] Step S2000, perform protocol pairing with the charger.

[0054] Step S3000, after the pairing is successful, open the air inlet and outlet, and start charging until the charging is completed. During the charging process, the fan of the charger keeps blowing air to cool the inside of the battery pack.

[0055] As an optimization, step S3000 specifically includes: after the pairing is successful, determine whether charging is required, if not, feed back to the charger and stop interacting with the charger, if so, turn on the power supply and fan, and start charging until the...

Abstract

The invention discloses a battery pack, a charging and heat dissipation control method thereof and a charger, belonging to the technical field of batteries. The battery pack is provided with a cooling air duct, an air inlet and an air outlet, and the two ends of the cooling air duct are respectively connected to the air inlet and the air outlet. When the device is turned on, the corresponding air inlet and air outlet are opened; the charger is provided with a fan inside, and the charger is provided with a fan outlet at the corresponding fan position, and the position of the fan outlet is the same as the position of the air inlet of the battery pack. Corresponding. The battery pack in the present invention utilizes the fan of the charger to dissipate heat inside the battery pack during the charging process, effectively ensuring the safety of the battery pack during charging, effectively protecting the performance of the battery pack and increasing the battery life. The service life is longer, and the air inlet and outlet are hidden when not charging, effectively reducing and preventing dust and debris from entering the battery pack.

Description

technical field [0001] The invention relates to the field of battery technology, and more specifically, it relates to a battery pack, a method for controlling charging and heat dissipation thereof, and a charger. Background technique [0002] Various existing rechargeable battery packs, when the battery pack is being charged, will generate heat during the charging process due to the impedance of its internal cells, connecting wires, contact points, and various electronic components. Severe heating will cause its performance to decline, shorten its life, and may even cause a fire. Contents of the invention [0003] The object of the present invention is to provide a battery pack, its charge and heat dissipation control method and a charger, so as to solve the technical problems that when the battery pack is seriously heated during the charging process, its performance will decrease, its lifespan will be shortened, and it may even cause a fire. [0004] Above-mentioned tech...
