Abstract

The invention relates to a battery protection plate and a manufacturing method thereof, a battery and a terminal. The battery protection board comprises: a hard circuit board; the at least two connectors are respectively connected with the hard circuit board and an external charging and discharging circuit; the hard circuit board is provided with a battery cell connecting end which is used for being connected with a battery cell of a battery; and the at least two connectors are respectively connected with the battery core connecting ends on the hard circuit board through at least two groups of current paths. According to the scheme provided by the embodiment of the invention, charging and discharging shunting of the battery is realized through the at least two connectors and the at least two groups of current paths in the circuit board, so that the temperature rise is reduced while the charging power is improved.

Description

technical field [0001] The present disclosure relates to electronic product technology, and in particular, to a battery protection board and a manufacturing method thereof, a battery, and a terminal. Background technique [0002] With the increase of fast charging and high-capacity requirements of batteries, the battery protection board needs to withstand a larger current, so the battery protection board needs more space and more protection devices in parallel to reduce the temperature rise of the protection board. However, to be compatible with the battery capacity, in the same space, the larger the space occupied by the protection board, the smaller the cell capacity, that is, the smaller the battery capacity; correspondingly, the larger the battery capacity, the smaller the space occupied by the protection board, so It is more difficult to guarantee the charging rate of the battery. SUMMARY OF THE INVENTION [0003] The present disclosure provides a battery protection ...
