Abstract

The embodiment of the invention discloses a battery charging method and a device. The method comprises the following steps: performing detecting processing on battery parameters of a battery to be charged, so as to obtain the type of the battery to be charged; stopping charging the battery when the type of the battery is a primary battery; and starting up a charging circuit to charge the battery to be charged when the type of the battery is a secondary battery. The device comprises a detecting module, a first charging control module and a second charging control module, wherein the detecting module is used for performing detecting processing on the battery parameters of the battery to be charged, so as to obtain the type of the battery to be charged; the first charging control module is used for stopping charging the battery when the type of the battery to be charged is a primary battery; and the second charging control module is used for starting up a charging circuit to charge the battery to be charged when the type of the battery to be charged is a secondary battery. The embodiment of the invention ensures that the adaptive capacity of a terminal product is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a battery charging method and device. Background technique [0002] Generally, AA-type batteries can be divided into primary batteries and secondary batteries. Among them, primary batteries are generally divided into alkaline batteries and acid batteries, which are cheap and easy to use; secondary batteries are generally divided into rechargeable batteries such as nickel metal hydride and nickel cadmium. Due to the high voltage of the primary battery and its unstable characteristics, it cannot support secondary charging. If the terminal charges the primary battery forcibly, it may cause safety risks such as explosion. For terminal products, charging is usually only for a specific secondary battery, and cannot support the use of primary batteries, which greatly limits the flexibility of users. Therefore, in order to support the cooperative use of the primar...
