Embodiment 1

[0024] An intelligent battery pack, including a battery pack 1 with multiple batteries, 5 batteries in this embodiment, a main control module 2, a step-up / down module 3 and a voltage level detection module 4, the overall battery pack 1 The output of the main control module 2, the step-up / down module 3 and the voltage level detection module 4 are electrically connected to provide working power for each device, and the output terminal of the voltage level detection module 4 is electrically connected to the input terminal of the main control module 2. Connect to the main control module 2 for providing voltage information required by different electrical products, the main control module 2 is provided with a PWM unit 5, the output terminal of the PWM unit 5 of the main control module 2 is connected to the step-up / down module 3 The input end of the step-up / down module 3 is electrically connected to adjust the output voltage of the step-up / down module 3, and the output end of the ste...

Embodiment 2

[0035] An electric tool, taking an electric drill as an example in this embodiment, includes a body 14 on which the smart battery pack described in Embodiment 1 is installed.

[0036] Preferably, the smart battery pack further includes a casing 15, and the casing 15 is detachably mounted on the body 14 of the electric drill. This setting not only enables the electric tool body 14 to be produced separately from the smart battery pack, but also greatly improves production efficiency by utilizing the versatility of the smart battery pack. The smart battery pack is all that is needed, which is more convenient to use, and when any of the smart battery pack or the body 14 is damaged, there is no need to replace it as a whole, and the maintenance is more convenient.

Abstract

An intelligent battery pack includes a battery pack having a plurality of cells, characterized in that: the intelligent battery pack also includes a master control module, a step-up / step-down module and a voltage level detection module, the output of the integral battery pack and the master control module, the step-up / step-down module and a voltage level detection module are electrically connected, the output end of the voltage level detection module is electrically connected with the input end of the main control module for providing voltage information required by different electrical appliances to the main control module, the main control module is provided with a PWM unit, the output terminal of the PWM unit of the main control module is electrically connected with the input terminal of the step-up / step-down module for regulating the output voltage of the step-up / step-down module, and the output terminal of the step-up / step-down module is electrically connected with the power inputterminal of the electric appliance product. The output voltage of the intelligent battery pack is adjustable, the design and production cost are reduced, and the versatility is good. In addition, theinvention also provides a power tool with adjustable output voltage of a battery pack, low design and production cost and good versatility.

Description

technical field [0001] The invention relates to an intelligent battery pack and an electric tool with the intelligent battery pack. Background technique [0002] Power tools with different voltage levels usually need to use their own standard battery packs, which is less versatile. Battery packs designed for different voltage levels require different numbers of batteries and occupy different spaces. Therefore, both the PCB board and the mounting shell need to be redesigned to meet the needs of different sizes, which undoubtedly increases design and production. the cost of. Therefore, there is an urgent need to design a smart battery pack with adjustable output voltage to meet the needs of power tools with different voltage levels. Of course, the design principle of the smart battery pack is also applicable to other electronic products, such as mobile phones, digital cameras, and notebook computers. Contents of the invention [0003] The technical problem to be solved by...
