Problems solved by technology

[0002] As the power source of wireless power tools, battery packs have always been the main link restricting the development of wireless power tools. In the past, battery packs often only had an output voltage below 30V. When they were driving high-power power tools, they often caused insufficient power and battery life. bad question
There is still no battery pack with an output voltage exceeding 30V and a safe and reasonable structure, as well as a charger suitable for the battery pack

Embodiment Construction

[0067] refer to Figure 1 to Figure 7 As shown, the battery pack 100 of the present invention includes: a battery case 11, a cell assembly 12, a connecting terminal 13, and a main control circuit board 14; the battery pack 100 has an output voltage of at least 56V. In terms of output voltage capability, it can output an output voltage of at least 56.

[0068] Wherein, the cell assembly 12 includes more than one cell unit 121, and the cell assembly 12 is a whole composed of a plurality of cell units 121 with a certain electrical connection relationship and arranged according to a certain structure, which is arranged in the battery case 11 as the power source of the battery pack 100. Of course, it is not excluded that the battery cell assembly 12 contains only one battery cell unit 121 .

[0069] The battery pack 100 should form a relatively compact structure in three-dimensional space, making it easy to carry, and also easy to plug into the corresponding charger 200 and elect...

Abstract

The invention discloses a battery pack and a charger suitable for the battery pack, wherein the battery pack includes: a battery case, a cell assembly, and more than two connecting terminals capable of transmitting electric energy or / and signals, and the battery case includes: The plug-in case wall, the cell combination includes: more than one cell unit; the plug-in case wall includes: the plug-in structure and the terminal interface, the plug-in structure has at least one plug-in direction, and the maximum projection of the plug-in direction and the cell combination The surface or / and the direction of the largest dimension form an included angle greater than or equal to 0 degrees and less than or equal to 45 degrees; the charger and the electric tool have a suitable structure, and the present invention is beneficial in that it provides a battery pack with a safe and reasonable structure and The charger suitable for this battery pack ensures the safe use of the battery pack during charging and discharging while achieving high voltage and high energy capacity.

Description

technical field [0001] The invention relates to a battery pack, a charger and a charging combination. Background technique [0002] As the power source of wireless power tools, battery packs have always been the main link restricting the development of wireless power tools. In the past, battery packs often only had an output voltage below 30V. When they were driving high-power power tools, they often caused insufficient power and battery life. bad question. There is not yet a battery pack with an output voltage exceeding 30V and a safe and reasonable structure and a charger suitable for the battery pack. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a charging combination with an output voltage exceeding 30V and a safe and reasonable structure. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A battery pack, t...
