Problems solved by technology

This results in a high cost of the digital battery system
At the same time, in terms of shape and volume, the internal space of small batteries is limited, especially for small cylindrical batteries, it is not easy to set up additional communication terminals.

Abstract

The embodiment of the invention provides a battery type identifying method and device and a power system, and relates to the technical field of batteries. By means of the battery type identifying method and device and the power system, by receiving an attribute parameter signal sent by a rechargeable device, and then demodulating the attribute parameter signal to obtain a type identifying signal,the center frequency of the type identifying signal is obtained, when the difference value of the center frequency and the preset frequency is smaller than or equal to a preset threshold value, a mismatching signal is generated to remind that a charger of a user is not matched with the rechargeable device, the occurrence of a short circuit and the like is avoided, and the safety coefficient of thepower system is increased; meanwhile, since the attribute parameter signal is a photoelectric signal, an electric quantity signal or the type identifying signal or the like can be transmitted, the type identification of the rechargeable device is achieved without addition of a data transmission terminal to the rechargeable device, and thus the size of the rechargeable device can be easily reduced; meanwhile, the cost for manufacturing the rechargeable device is saved.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery type identification method, device and power supply system. Background technique [0002] Batteries are widely used in various digital products, household appliances, instruments, toys and other devices. With the improvement of people's living standards, the number and types of batteries used are also increasing. Batteries are divided into primary batteries and rechargeable secondary batteries. Due to performance and environmental protection requirements, secondary batteries can be more widely developed and applied. [0003] In many application modes, the battery needs to be charged through a charger or a charging stand. The most basic and important requirement is to protect the safety of the user and property. With the increase of battery materials and voltage types, the safety hazards in the battery charging process have risen sharply, such as dry batteries...
