Embodiment Construction

[0116] see figure 1 , which is a circuit block diagram of the charging module 10 in an embodiment of the present application.

[0117] Such as figure 1 As shown, the charging module 10 includes a first circuit board 11 , a second circuit board 12 , a third circuit board 13 and a battery module 100 including a battery cell 14 and a first battery protection board 15 . The first circuit board 11 , the second circuit board 12 and the third circuit board 13 cooperate to process the charging voltage and current received from the outside into a voltage and current suitable for charging the battery module 100 . The battery module 100 receives the processed voltage and current and charges and stores electric energy. At the same time, the battery module 100 can also release the stored electric energy to the third circuit board 13 for discharging, providing power for the third circuit board 13 and other functional circuits. (not shown) provide driving power.

[0118] Specifically, the...

Abstract

The embodiment of the invention discloses a battery module supporting high-power fast charging. The battery module comprises a battery cell, and the battery cell comprises a battery cell body, a first tab, a second tab and a third tab. And the first tab, the second tab and the third tab are electrically connected with the battery cell body respectively. The first tab and the third tab have a first polarity, and the second tab has a second polarity. And the second tab and the first tab are matched to input voltage and current to the battery cell body or output voltage and current from the battery cell body. And the second tab and the third tab are matched to input voltage and current to the battery cell body or output voltage and current from the battery cell body. The first polarity is different from the second polarity.

Description

technical field [0001] The embodiments of the present application relate to charging technologies, and in particular to a battery module supporting high-power fast charging, a charging module, and an electronic device. Background technique [0002] Currently, the charging system used in the electronic terminal includes a processing circuit and a battery cell. The processing circuit processes the charging voltage and charging current received from the outside and supplies them to the battery cell. The battery cell performs electric energy storage according to the charging voltage and charging current. In the prior art, each cell includes a positive tab and a negative tab, and the positive tab and the negative tab provide a charging path and a discharging path for the cell. [0003] With the increasing demand for fast charging of batteries, in order to solve the problem of fast charging, the existing technology can increase the charging speed by adding batteries and processi...
