Embodiment Construction

[0035] The battery pack control unit 12 is electrically connected to each battery of the battery pack 11, and is used to detect data such as the voltage of each battery and the temperature of the battery pack, and judge the working state of the battery pack based on these data. The control unit 12 may be a logic circuit composed of components to realize corresponding functions, or a microprocessor integrated with programs and instructions. In this embodiment, the battery pack control unit 12 is a processor, which generally includes a microprocessing module (MCU), a read-only memory (ROM) module, a random access memory (RAM) module, a digital / analog conversion unit ( A / D converter) module, timer (timer) 221 module, input / output port (I / O port) module etc., because the function and working principle of these modules are all familiar to those of ordinary skill in the art, so apply People will not repeat them here. It should be noted that in this embodiment, the voltage of each b...

Abstract

The invention relates to a battery pack which is used for supplying power for wireless electric apparatus by discharge, or is charged by being connected with a charge unit. The battery pack comprises a plurality of batteries, positive and negative terminals that are in series connection with the batteries, electronic control units connected with the batteries, and status indicating terminals connected with the electronic control units, wherein the electronic control units are used for detecting the voltage and the temperature of the batteries, judging the working status according to the detected voltage and temperature and generating status indicating signals representing the working status of the battery pack; and the status indicating terminals are used for outputting the status indicating signals. The battery pack can effectively reduce design and manufacturing costs by such an arrangement.

Description

technical field [0001] The invention relates to a battery pack, in particular to a rechargeable battery pack. [0002] The invention also relates to a combination of a battery pack and an electrical device, in particular to a rechargeable battery pack and an electrical device matched with the battery pack. Background technique [0003] In recent years, with the development of battery material technology, the capacity of batteries has been greatly improved, and its application range has also extended from some low-power electronic electrical devices to some high-power power electrical devices, such as electric tools wait. In this way, the electric tool using the high-rate battery can be freed from the shackles of cables and can be used anytime and anywhere. In order to improve the utilization rate, these batteries usually adopt rechargeable batteries, such as nickel-cadmium (Nickel-cadmium, NiCd) batteries, nickel-metal hydride (Nickel-Metal Hydride, NiMH) batteries, lithiu...
