Problems solved by technology
[0008] The embodiment of the present invention provides a power battery pack with intelligent output current, which aims to solve the existing matching scheme of the MCU communication mode of this portable electric tool. Because of the high cost and complicated assembly, few manufacturers adopt it, and generally adopt paired shipments. This makes the power battery pack (PACK) not universal, resulting in a serious waste of resources

Embodiment Construction
[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0042]It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0043] It should also be noted that the orientation terms such as left, right, up, and down in the embodiments of the present invention are only relative concepts or refer to the normal use state of the product, and should n...

The invention is applicable to the technical field of a power battery, and provides a power battery pack and a method for intelligently outputting current. The power battery pack comprises a battery body, a printed circuit board (PCB) control plate and a power transmission interface, wherein the PCB control plate is electrically connected with the battery body, the power transmission interface is provided with a first power transmission pin group, the first power transmission pin group is electrically connected with a second power transmission pin group of a charging interface of an electric tool to be charged, an identification resistor is connected in series between loops formed after the first power transmission pin group and the second power transmission pin group are connected, the PCB control plate is provided with an identification control chip, and the identification control chip is used for acquiring a resistance value of the identification resistor and outputting a power transmission current corresponding to the resistance value to the second power transmission pin group of the electric tool to be charged. With the power battery pack provided by the embodiment of the invention, the problem that an existing portable electric tool cannot be used universally to cause serious resource waste due to shipment in pair is solved.
Description
technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a power battery pack and a method for intelligently outputting current. Background technique [0002] Due to people's increasing attention to environmental protection, the use of nickel-cadmium batteries is being more and more restricted. In order to replace portable electric tool batteries, it has become a top priority to develop new types of safe, environmentally friendly, and economical high-power secondary batteries. In recent years , with the continuous development and application of various new technologies of power lithium batteries, the high power performance, safety and reliability of lithium batteries have been greatly improved, which can meet the basic requirements of electric tools for battery performance, and the cost is constantly increasing. decline, which has effectively promoted and promoted the application and development of lithium batteries...
