A battery unit, a terminal device, and a battery verification method. The battery unit includes: a battery interface unit configured to connect with a terminal part and provide power to the terminal part; and a battery management unit configured to perform a connection between the battery unit and the terminal part. The battery is matched and supports a first battery verification mode and a second battery verification mode, wherein when the terminal part is connected to the battery unit, the battery management unit receives a random signal from the terminal part through the battery interface unit. verification code; the battery management unit determines the length of the random verification code; and determines whether to perform battery verification through the first battery verification mode or the second battery verification mode based on the length of the random verification code, and Feed back the battery verification response to the terminal part.
Description
technical field [0001] The invention relates to a battery unit, a terminal device and a battery verification method. Background technique [0002] Currently, with the popularity of terminal equipment such as laptops, more and more counterfeit batteries appear in the market. Using counterfeit batteries may affect the battery life and service life of the terminal device. Therefore, currently there are various battery verification technologies to verify whether the battery of the terminal device is a legitimate battery. Here, since different types of terminal devices (such as Thinkpad or Ideapad) usually use (support) different battery verification technologies, it is necessary to design batteries supporting different battery verification technologies for the above-mentioned terminal devices, resulting in that the above-mentioned batteries cannot be used in different types of devices. common in terminal equipment. Contents of the invention [0003] In order to solve the ab...
