Abstract

The invention discloses a battery protection board assembly, a battery assembly and a mobile terminal. The battery protection board assembly comprises a battery protection board for protecting charging and discharging of a battery, and an over-current protection component arranged between the battery protection board and a first electric conductor. Through the battery protection board assembly, the space resources of the protection board can be prevented from being occupied while secondary protection for the battery is realized, so that the battery is more flexible in design and higher in selectivity.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery protection board assembly, a battery assembly and a mobile terminal. Background technique [0002] As a necessary accessory of various terminals, the battery not only directly affects the user's use by its basic performance, but also directly affects the personal and property safety of the user. Therefore, at present, batteries all have protection circuits to protect the batteries from overcharging, overdischarging, and short-circuit and overcurrent protection. In order to make the short-circuit over-current protection more reliable, a secondary protection element, such as a PTC resistor, will be added to the design of the protection board, that is, when the short-circuit over-current protection of the protection circuit fails, it will independently play the role of over-current protection. [0003] The current protection board design generally places PTC resistors on the prot...
